Some rezoning hearings coming up this August

Below are some comments for the Durham City Council meeting tonight, August 1st, and there will be several other rezoning/annexation hearings this month, including for 4150 Old Chapel Hill Road [, at the corner with Garrett Road, among other sites,] August 9th [this is actually a Planning Commission hearing], and the Courtyards at Farrington Civil War Trails site, by the old [Patterson’s Mill] country store, August 15; see: www.durhamnc.gov/AgendaCenter/City-Council-4 [www.durhamnc.gov/AgendaCenter/Planning-Commission-15 ] There is also a Durham Rail Trail comment period and information about ShotSpotter implementation in the news.


Durham County Utility Building at the corner of Highway 55 and TW Alexander Drive

I mentioned this project in a previous post: www.northeastcreek.org/wordpress/where-the-red-fire-pink-blows-and-other-campions-in-the-triangle/ Neither community consultation meeting provided much information, though I felt somewhat better about participating in the second meeting. I thought the County was buying the site to expand the Triangle Wastewater Treatment Plant, and that is what Planning Commission members seemed to think, yet now it is supposed to be a County administrative building. I think WWTP expansion was denied at the meetings, but I could be mistaken. Given that the site was a large hill, there is probably very hard, possibly igneous, bedrock just under the surface and it would be difficult to build on. The treatment plant was rattled back then, according to the staff, and there might be the possibility of damage from renewed blasting. The area is “culturally significant” for me, and presumably for the people who once lived there, and it wasn’t merely clearcut – a large, wooded hill was blasted away night and day more than 10 years ago to build something like 540, with the remainder reportedly being dumped in the abandoned claypit across 55, now acres of mass grading at “55-Hopson” and most likely the reason Northeast Creek is quite opaque yellow at the Grandale Road bridge.

It would be good to preserve the old farmpond on the County site, where I have seen people fishing, which relates to the Community Goals and Objectives about food, accessibility, etc., though those people were probably displaced by the Council’s friends at the nearby Social Security Administration printing facility, as they have tried to do to me. These are apparently still publically-owned roads and the SSA doesn’t own any land south of the railroad tracks, on “Experiment Drive.”

I don’t know that there are any rare species on the County land now, but rare plants grow very close by and red fire pinks, seemingly very rare in Durham, grew just beyond the property lines and probably still grow somewhere in the vicinity. They might like the new openness of the site. Buttercups have been common in the still mostly treeless field where the wooded hill once was. Given that the field doesn’t seem to be mowed, is it treeless after about a decade because there is very little soil? It seems like potential open habitat for meadowlarks, a bird in decline in North Carolina.

The landscaping of an administrative building and the naming could relate to the ‘flavor’ of the local area and/or areas not built on could be managed in a way beneficial for plants such as fire pinks, but that is not addressed at community consultation meetings and probably not at Council hearings. If the site is rocky and denuded of topsoil, it might also be difficult to landscape conventionally and might require more water than usual to sustain lawn grasses and ornamentals. The Main Library had an example of probably xeric herb gardening at the entrance. A large area of mown lawn, with the lake across 55 at the WWTP, would probably attract Canada geese, possibly onto the roads.

This is also a gateway to Durham, formerly with trees and April-blooming blackberries. Other woods were cut on the north side of TW Alexander for a residential area recently and there was a residential rezoning of the old house east of the County site, another area with some wildflowers, mainly early spring woodland species, as well as some ornamental roses, though there is also invasive Vinca minor. Water from the County site drains both north and south, possiby mainly north, so where would the stormwater pond be located? The State Employees’ Credit Union branch a short distance north at the corner of 54 and Alston seems like a good example of stormwater retention pond landscaping, also attracting flocks of geese.

The farmpond drains into a clear, rocky small stream. Despite the small size of the waterway it apparently doesn’t dry up completely during the summer and so supports sunfish of some kind, possibly somewhat rare salamanders, and an abundance of crayfish, as well as having waterfalls over the igneous rock and many wildflowers.

Light pollution from the County site and 55-Hopson would impact the large area of gameland along Northeast Creek on the other side of 55. Would there be large parking lots for County vehicles, lit all night? Again I can’t remember what was said at the meetings about the storage of County equipment; maybe there won’t be storage there. Lit-up parking lots could be a hazard for migrating birds. There seem to be a lot of moths in the area, which would be adversely impacted by adding more lights. Annual National Moth Week was just a last week.

What about chemical spills near Northeast Creek, including road salt and oil or gasoline from County equipment? There might be few beaver ponds in the area to intercept a spill before it reaches the main Creek.

What does 55-Hopson plan to build across 55 near the County site? They voluntarily renounced some uses at 55-Hopson – except along 55, so what are they planning? The government allowed a text-only development plan, so there is no way of knowing now without a whistleblower, and there was just a whistleblower appreciation week. I am observing and will report any possible violations. After recent rains Northeast Creek is very opaque and yellow at Grandale Road from some source, and the hundreds or thousands of people using the Tobacco Trail every week must see it as well. Unlike in other nearby towns the land in southern Durham County seems to bleed readily when mass graded, and everyone can see.

In addition, local government wants to increase traffic on Grandale, and the DOT sprayed herbicide all over, but there is still a danger that someone will be hit by a vehicle at the narrow bridge. Given the the area is already dangerous and a known corridor for wildlife, why do the DCHCMPO’s planners think increasing traffic is a good idea?

It might be good to have an access to the County site on Experiment Drive, unless the County brings in security contractors/domestic mercenaries who behave like the SSA’s, I’m not going to be “displaced.” I think that is where the driveway to the farmhouse on the hill once was. Maybe 55-Hopson will bring over-zealous faceless corporate entity security contractors even closer, in addition to the vigilantes and the policing establishment.


East Cornwallis

Regarding East Cornwallis, from the aerial photo it does seem to be a residential area, or residential adjacent to industrial, though I didn’t know there were Cannabis growing operations in Durham. A car dealership would probably be very bright at night and there would be few trees buffering it, judging by the larger dealerships near Southpoint. On the other hand the site might already be very lit up if there are greenhouses nearby. What about the risk of oil and other toxic spills in the headwaters of Northeast Creek? A car dealership would probably heat up the surrounding area. Climate change is contributing to unusual heat waves, fires, floods, and crop losses filling the news around the world this year, but cutting trees and paving the land will increase local heating quickly and increase electricity demand. Someone commented at the community meeting about the need for sidewalks there, which is probably a good idea.

As with Hopson-55 the Morningstar Law Group is saying that they renounce some uses, leaving unclear what the intention is, though in this case it is a much smaller area and not on the edge of Durham, next to parkland. Too late to comment on Hopson-55 I heard that bobcats and coyotes have been seen adjacent, but it isn’t clear if they will still be there in a few years. I also began to worry about how much earthmoving is envisioned along 55, where there no commitments were made. Has the small area north of the powerline been cleared? They even offered not to build there at the Planning Commission meetiing if not at the City Council hearing, but it was not made a committed element, so did they clear it anyway, and for what purpose? Was all that land clearcut to create biomass fuel for European powerplants? This fuel source has been condemned by some groups. There is what looks like a very large chipper installed across from the construction entrance.


Garrett Road/751

On Garrett Road the application is for only a few townhomes, but paying a fee-in-lieu of open space requirements doesn’t sound good. While there is a vast area of what I assume is protected New Hope Creek floodplain “encumbrance” around the site, if animals need upland areas as well, those have probably largely been built on, as shown in the aerial photo. My impression is that most City or County parks are for things like athletic use, rather than to protect land that would otherwise be built on. There are parks in the Triangle that are supposed to have Catesby’s trilliums in the spring, but I have long wondered why there aren’t any in my area. If they prefer the dry uplands maybe they were plowed under by agriculture and building long ago, though for some reason not in northern Durham and Orange counties.

I expect there is a long history of people living along Garret Road, similar to how people long lived along Fayetteville Road, but they left in recent decades and the old houses have since been razed or covered up. There are also obviously thousands of years of human habitation buried in the ground, and maybe it is a matter of who knows what is buried where and a bulldozer operator probably won’t notice what gets scooped up.


The Courtyards at Farrington

Regarding the Courtyards at Farrington, coming up at the August 15th Council meeting, how can Durham allow the destruction of what is apparently the only Civil War battleground in Durham, with historic buildings, part of the national Civil War Trail and probably with designated historic buildings? What is the exact nature of the Civil War Trail designations on Farrington and at Leigh Farm, cut through by I-40? It reminds me of the NC NHP reports in relation to 55-Hopson. I saw a meadowlark near Farrington Road once, so they could be present on this grassy old farm. Unlike 100′ of woods on Farrington Road, the large hill on the County site probably did block a lot of traffic noise.

Explore upper New Hope Creek around Johnston Mill Nature Preserve

The Triangle Land Conservancy’s Johnston Mill Nature Preserve, established in June 1999, protects 296 acres along upper New Hope Creek. Much of the Triangle is in the New Hope basin, including major tributary Northeast Creek, and most of the Jordan Lake reservoir, a source of water for several municipalities, sits in the valley of the New Hope River. The lower end of New Hope Creek meanders across wide bottomlands in the Triassic Basin, while at Johnston Mill the Creek, still surprisingly wide, is clear and rocky like the Eno and there are stony remains of gristmills. I didn’t see any fish when I visited in mid-February, though I also didn’t make a special effort to find them, but this should be a good place to watch fish building their nests and spawning in the spring and early summer. In February a spring bloom of algae grew on cobbles in shallow sections with the increasing warmth and daylength. Much of the surrounding forest is not especially old, though there are some large and old trees, but it still shelters many rare to threatened species and is very biodiverse; for example more than 125 bird species have been seen and there many species of early-blooming and often very uncommon woodland wildflowers. The mix of fields and old to young forest, ranging from dry hilltops down to riparian edges, heightens biodiversity and the Preserve roughly links segements of Duke Forest for species that need large areas of contiguous forest. Being just north of Chapel Hill and near Durham, this seems to be one of the TLC’s busier preserves, especially near the Mount Sinai Road entrance. I found someone’s painted #Rockhunt cobble hidden between two trees far out on the Old Field Bluff Trail.

The reddish soil has numerous rocks, metamorphic or maybe igneous, unlike the generally sedimentary and relatively soft bedrock laid down in the Triassic Basin. Jagged outcroppings, a few supporting Polypodium ferns, and exposures in creek beds reveal vertically upturned bedrock.

The TLC says Johnston Mill has beech up to 150 years old, and there are large oaks. White and Northern red oaks, along with red maples, are common on the hilltops while lower down there are large, uncarved beech and May-blooming tuliptrees, above summer-blooming sourwoods. Elsewhere sycamores, hackberries, sweetgums, shagbark and other hickories, sugar maples, ash, and three species of pine grow above ironwood, hophornbeam, red cedars, black cherries, and occasional hollies. Black walnuts are most frequent in the younger woods in the northwest of the Preserve, along a high-tension powerline, where the forest intergrades with rural farmland and a few houses. Large lianas dangle from the canopy, including grapes and trumpetcreepers, attracting hummingbirds. These massive vines probably grew together with the original woody old field pioneers, such as the tuliptrees and sweetgums. Early-blooming spicebush and painted buckeyes grow near the streams, especially in the northwest section of the Preserve. There might be fringetrees, which bloom later in April. Elms, almost ready to bloom when I last visited, and a few boxelders and birch border the creeks. Throughout the Preserve what must be crownbeard, a tall yellow composite flower that blooms in late summer, is abundant and there are the stems of last summer’s mullein, mint, millkvine, dogfennel, nightshade, and broomsedge. The NC Natural Heritage Program’s inventory of significant natural areas in Orange County says “this is one of the most pleasing forest areas of its size in the county” and “The diversity of spring-blooming herbs is also extremely high and of great aesthetic value,” and includes early-blooming Hepatica, trout lilies, rue anemones, spring beauties, toothworts, jack-in-the-pulpit, and very rare Catesby’s trilliums (I don’t think I have ever seen any trillium species growing wild). Evergreen Christmas ferns, mosses, clubmoss, wild ginger, and May-blooming pipsissewa stood out in the leafless winter forest.

Shortly after walking in from the Turkey Farm Road entrance I saw a golden-crowned kinglet fluttering, gleaning the bare twigtips, a rare sight for me, though maybe not the first time after all, and it was just where Liz Pullman’s write-up for the Carolina Bird Club says to look for them ( www.carolinabirdclub.org/birdingnc/johnston_mill.html ). A belted kingfisher loudly patrolled along New Hope Creek. I saw, heard, or found evidence of 4 to 5 woodpecker species, white-breasted nuthatches, thrushes, hawks, barred owls, turkey vultures, brown thrashers, white-throated sparrows, what I think were savannah sparrows, possibly a phoebe, and several other species. Many warblers, both summer and scarlet tanagers, flycatchers, vireos, and other birds not often seen in yards can be seen in the bottomlands, especially during migration. Turkeys, bobwhites, hawks, yellow-breasted chats, indigo buntings, and similar blue grosbeaks can be seen in the open areas. According to the NC Natural Heritage Program Inventory 21-23 species nested near Old Field Creek annually during the 80’s, including the more montane broad-winged hawks and worm-eating warblers.

Catawba rhododendrons, galax, trailing arbutus, saprophyte sweet pinesap, and foamflowers (another wildflower I have only seen cultivated) grow a short distance downstream in Duke Forest, at least partially accessible from Mount Sinai Road. There more typically western and montane plants, nesting cedar waxwings, red salamanders, and large red sumo mites meet more eastern dwarf waterdogs, yellow-bellied sliders, and snail bullheads.

Eastern chipmunks live in Duke Forest if not here, and the leafy nests of gray squirrels were very visible in late winter. A dog off-leash flushed out three or more hidden deer, and a small herd stood by Turkey Farm Road in the twilight as I left; the deer warning signs in the area are very appropriate. There were signs of beavers; river otters live in parts of New Hope Creek, possibly including Johnston Mill.

It was sunny and cold, but what were probably upland chorus frogs sang briefly near the Turkey Farm Road bluff in early afternoon. It didn’t feel that cold, but the temperature might have been in the 30’s and the wind picked up later. Marbled and spotted salamanders, Northern cricket frogs, and others breed in the bottomland while four-toed salamanders and gray petaltails, rare and primitive dragonflies, breed in hillside seeps. I saw a pickerel frog, similar to a leopard frog but earth-colored, with rectangular spots, and poisonous to other frogs, in rural Orange County when I was very young and never again anywhere else, though they can supposedly be found statewide, and they have been seen hereabouts. I am also impressed that queen snakes, a species more common in western NC and specializing in crayfish, especially recently molted, ‘soft-shelled’ ones, can be found downstream in Duke Forest.

Despite the lingering cold I found some arthropods, a small brown ant and small gray spider, as well as a large mantis eggmass, possibly from a Chinese or praying mantis, and many hackberry leaf galls. Getting to Johnston Mill small yellow daffodils, brilliant blue bluebirds, and a thrush were out as spring approached.

Seasonal Nature Notes for winter

This is a revised version of an article I wrote for Cathy Starkweather’s South Durham Green Neighbors Newsletter, posted each month on the sdgreenneighbors Googlegroup (there is also a Facebook group), outlining some of the natural sights and wonders people can look out for this winter.

Seasonal Nature Notes

Despite the cold winter weather, some plants regularly or potentially bloom in December. East Asian camellias bloom in yards from fall into spring, depending on the variety. They don’t seem very attractive to insects, but yellowjackets check them out in the fall. Red maples can start blooming well before spring and when they do small insects can be seen flying around the canopy on relatively warm days.  Many years ago pastel pale blue bluets bloomed in December outside Eno River State Park’s main office, though they normally bloom months later. Peaches on the south-facing side of Occoneechee Mountain in Hillsborough also bloomed in winter that year and still developed fruit. There were cold temperatures that winter, and there were frigid and icy mornings on the shaded north side of the small mountain. I was surprised to see a white atamasco or Easter lily, usually a flower of mid-spring, blooming near Little Creek in Orange County in early November 2020, after herbaceous brush had been cleared. Hepatica, a pale lavender to blue, and occasionally white or pink, early spring woodland wildflower often found on rocky hillsides, can bloom in January or February if not December. Witch-hazel, a diminutive relative of sweetgums, also might bloom on hillsides around now. This is also a good time of year to look for evergreen mistletoe, a semi-parasitic bush growing in the bare treetops. It is common on silver and red maples near the intersection of Sedwick and Revere roads and it often appears on oaks along city streets in downtown Durham, Chapel Hill, Cary, and Raleigh. It seems to be most common in built up areas but sometimes grows on red maples around beaver ponds and large waterways. It was unusual to see one high in a Northern red oak surrounded by other trees at Cary’s Hemlock Bluffs Nature Preserve, near but not immediately next to Swift Creek. There are a few deciduous tree species that mistletoe seems to prefer, but it can grow on a range of native and non-native trees. Recently I have been admiring the shape of the fallen leaves, especially those of Spanish or Southern red oaks. There are many species of oak, each with a different leaf shape, and the form of each leaf is individual, depending on how shaded it was, its history during the growing season, etc. Oaks are among the last trees to lose their leaves, probably finishing in early December, and some oaks and other trees regularly retain their earth-colored dead leaves until spring, at least when young. The whitish paperlike leaves of related American beech, increasingly common in Parkwood, are picturesque in brilliantly lit deciduous woods in winter. Lingering winged seeds can be seen in the skyscraping crowns of bare tuliptrees along Northeast Creek and the sweetgum gumballs won’t fall off for a few more months and attract seedeating birds during the winter. Fruit might linger on plants such as greenbriars, hollies, hawthorns, and Japanese privet while December is likely too late for the last American and Asian persimmons. Apparently cedar waxwings can be poisoned during the winter by the red fruit of Nandina, an East Asian shrub with compound leaves.

It seems like live oaks drop their acorns in winter and other oaks might still be scattering the last of their acorns in early December. The official Landscape Manual for Durham recommends against planting Virginia live oaks, native along the coast into Virginia, but those growing around the old Parkwood Shopping Center, at the intersection of Revere and Seaton roads, don’t appear to have any problems with damage from cold temperatures or ice and their acorns, very abundant under the trees around now, sprout if scattered in yards while still viable. The only drawback might be that they grow slowly, at least when somewhat shaded. Live oaks are evergreen, hence their common name, but might have fewer leaves during the winter. Young oaks of many species are often semi-evergreen or retain dead leaves in winter, and water oaks, which are native to Durham and have reached a pretty large size in some yards and on the UNC campus, are a little closer to being evergreen. This is another native oak Durham seems to unfairly malign, claiming that it is prone to “untreatable decay,” and they have problems with the supposedly “exotic” pin oak, which seems to be native in central NC if not Durham. They did not seek public input before updating the manual in 2020. Oaks often turn red in the fall, some species strikingly so, but when fallen leaves are picked up they are usually more brown than red.

This is a good time to look for migratory waterfowl, including American coots, pied-billed grebes, ring-billed gulls, non-resident Canada geese, and ducks such as black scoters, long-tailed ducks, and mergansers. Some species, such as hooded mergansers, can stay well into the spring and might breed here but it seems like the majority of the migrants fly north by or in February. I like to look for them at Crabtree Lake in Cary but they also visit Parkwood Lake, large stormwater ponds, the waterfowl impoundments, and sometimes even small beaver ponds (see my February 2014 article at www.northeastcreek.org/wordpress/784/ ). I sometimes spot unusual shorebirds, terns, etc. at various times at the large reservoirs, but only one or a few at a time and it is easier to search smaller lakes. Migrating shorebirds can also turn up on dry shorelines around small beaver ponds. Small flocks of colorful wood ducks can be seen in Northeast Creek now, but they are very wary and I usually only catch a glimpse as they shriek and fly off. Woodcocks or just their tracks and probings can be found along waterways in winter, though I might see them more often in late winter than now. Seeing a well-camouflaged woodcock usually means not seeing it until one gets close and it flies away, though maybe not with quite the speed of a wood duck. Flocks of turkeys and their tracks can also be found in bottomlands in winter; despite their reputed wariness about 20 landed above me in a swampy area after sunset on a Thanksgiving Day, and I think they didn’t fly off as I left. Maybe they were experienced enough to know I wasn’t hunting. According to John K Terres they roost over water for protection from great horned owls and presumably other predators. Woodcocks start displaying around January and the NC Botanical Garden usually has excursions to see their displays, rising 300 feet in the air above open areas at nearby Mason Farm Biological Reserve as night falls. Barred owls, bald eagles, and hooded mergansers are among the birds that can begin to breed in December or January. The plaintive calls of yellow-bellied sapsuckers are a common winter sound in Parkwood. These migratory woodpeckers spend winter here, chiseling rows of holes in many tree and shrub species for sap; they also eat insects. They breed further north and at high elevations in Western NC. Other birds and insects also visit sapsucker holes, potentially including overwintering butterflies. Wounded trees, as well as fruiting persimmons,are good places to look for butterflies in the fall. The ground can be heavily littered with fruit under untended pear trees, but in my experience they don’t seem very attractive to butterflies and other insects, or maybe it is late in the season.

Winter is also a good time to observe some insect life stages, such as the egg masses of mantises and Eastern tentworms and the large cocoons of some giant silk moth species. I frequently see large cocoons dangling from the twig tips of birch planted around buildings. Some species attach their cocoons to the twigs while others allow their cocoons to fall with the leaves, one reason it is important to leave fallen leaves. For example, both promethea or spicebush and tuliptree silk moth caterpillars can be found on tuliptrees, but promethea caterpillars usually spin their cocoons so they won’t fall while tuliptree moths let them fall. Related polyphemus moth caterpillars usually either travel to the ground to pupate or fall with the leaves. Sometimes they do attach their cocoons to twigs, and these might be the cocoons I see on birch. This group of very large moths can be found in Parkwood and there are plants for their caterpillars, but they seem more abundant in places like UNC and Falls Lake. Insects have many ways of surving winter and one frigid winter morning I jostled a holly and very small green inchworm caterpillars dangled on silk, though the ground below was hard with ice. At other times I have seen insects and spiders out as snow melts. Carolina wrens and other birds can be seen investigating lingering dead leaves. The various species forage in different ways, searching the tips of branches or along trunks and working in different directions, avoiding competition. Galls created by insects or other organisms can be seen on the stems of goldenrods and other plants. Under hickories carefully pruned twigs can be found, cut off by twig girdling beetles. The round exit holes of weevil grubs can be seen in this year’s acorns and other nuts. Don’t bring eggs masses, cocoons, etc. indoors for long or they might hatch early, with disastrous results. It is now safe to examine the nests of social paper wasps, often hidden in brush or under eaves and bald-faced hornet nests suspended from tree branches. I sometimes find the tiny mud vases of solitary potter wasps hidden in closed up wild carrot or Queen Anne’s lace seedheads. Even on what seem like freezing nights some moths can be on the wing, as well as bats. I found a large gray hoary bat roosting at ground level on the outside of UNC’s Greenlaw building one day in mid-January. During warm spells hibernating butterflies and moths can appear and in some cases last year’s caterpillars emerge as adults, possibly too early. Black swallowtail butterflies, especially males, frequently hatch when it seems too early, and it might have been on a night at the end of a warm spell in December, with the wind picking up as a cold front approached, that I saw a large pastel green luna moth unseasonably fly by a streetlight at Eno River State Park.

Depending on the weather early spring frogs can start singing in December. I sometimes hear individual frogs call quietly on mild, cloudy days in the fall and while species such as upland chorus frogs are so loud in late winter and early spring it might be easier to actually see them in the fall and summer. Marbled salamanders silently court and lay eggs in dry depressions in early fall, females guarding their eggs until these vernal pools fill up. The dark brown or black larvae with a collar of frilly gills can be seen, developing front legs first, unlike frog and toad tadpoles. What are probably marbled salamander larvae can be seen in the bottomlands around Northeast Creek and in puddles next to some nearby roads. Like frogs and toads they can breed in pools created by human activity, though they seem to prefer ‘wilder’ pools. Construction destroyed some nearby breeding pools and might have killed off the adults and they also get killed crossing roads to reach their customary breeding locations. Closely related spotted salamanders breed later, dancing underwater in the now brimming pools, and their larvae can be prey for the older marbled salamander larvae. At least in the case of spotted salamanders breeding adults prefer to return to their natal pool, and can follow the same route every year. I haven’t ever found an adult spotted salamander myself, so as far as I know they aren’t found in southern Durham County, but I occasionally find marbled salamanders hidden under debris on moist hillsides near creeks. Spotted salamanders famously breed in large vernal pools at the NC Botanical Garden in Chapel Hill and there are usually tours, which fill up quickly. One or more small salamander species can be found in Parkwood’s streams, possibly only breeding there, but they are well hidden or uncommon so I rarely see them. Salamander biodiversity is very high in North Carolina but they are usually not as conspicuous as frogs and toads.

I think of lizards as animals of summer but Carolina or green anoles are easy to see in the fall and winter. I first noticed them in Parkwood about 10 years ago and several moved into my yard in the summer of 2020. I wonder if this is a sign of climate change, but they were known in Chapel Hill by at least 1995 and according to roadsendnaturalist.com/2021/09/05/yard-mystery/ anoles have lived in that part of Chatham County for at least decades. I started seeing them in Orange County around the same time as in Parkwood and a few years ago they were common in places at Jordan Lake State Recreation Area. I haven’t seen them further north near the Eno, though Falls Lake is a rich in reptiles, including species that I had not realized live in the piedmont. Despite changing color to match their surroundings, anoles are conspicuous and I would have noticed if many had been living around here. Last fall and winter I would often see them on sunny south-facing walls and an air-conditioning unit, even in December, and I was afraid that they might not survive the winter, but they did and were out again this year. Fence lizards live or lived at Parkwood Elementary School, spiraling around trees to escape capture, but otherwise seem very rare in this part of the Triangle. They are common in places at Falls Lake State Recreation Area. I found one near the Eno on a cold, wet day, probably in late fall or early winter, but it seemed dangerously chilled. I can’t recall seeing any skinks out in fall or winter.

The Northern Hemisphere’s winter solstice is Tuesday, December 21st this year, when the night will be longest. Daylength changes little from day to day close to the solstice, but changes faster closer to spring. I thought the first frost was usually in mid-November, and that was the case this year, but some sources ( such as gardening.ces.ncsu.edu/average-first-and-last-frost-dates/ ) say it is earlier. We can get significant snow in December, but the coldest temperatures are usually in the New Year, in late January, when snowstorms are more likely and snow and ice can linger. The Earth’s orbit actually takes us closest to the Sun during the Northern Hemisphere’s winter, but the Earth’s tilt reduces the amount of heating produced by the Sun’s rays and it takes time for the land and oceans to warm or cool. For a few years it seemed like we often had balmy weather in late December. So far mild to warm weather is forecast for much of early December.

Winter is the best time to see atmospheric phenomena created when sun or moonlight interacts with ice crystals in motion, in clouds such as cirrus and cirrostratus, though optical phenomena can appear in any season. There are many kinds, including various haloes around the Sun or Moon, often indicating approaching stormy weather; sun and even moondogs, also called mock suns/moons and parhelia/paraselene, on one or both sides of the Sun or Moon; circumzenithal arcs, like rainbows in the center of the sky; and many other kinds, ranging from relatively common to very rare. Around midday on about November 15, 1996 the sky over southern Durham seemed to be full of lines and I wonder if anyone else noticed. That might have been when I first noticed sundogs. There are also the optical effects created by water droplets; rainbows are more common in the summer, but coronas often form around the Moon when it shines through a thin bank of the mid-level cloud altocumulus.

With the Sun setting early and the trees bare, this is also a good time to see both the colorful sunset in the west and the bands of color in the east as we enter the Earth’s shadow.

The night sky is also interesting and the sky is often limpid if burning cold in winter. Venus, Saturn, Jupiter, and Mercury will be plainly visible in the evening and Uranus and Neptune will be visible through binoculars. Before dawn on the 31st the delicate, gleaming white waning crescent Moon, reddish Mars, and the reddish star Antares, in the heart of the constellation Scorpius, will appear close together low in the southeast. Scorpius appears shortly before the Sun rises now, but is up much of the night during the summer. Comet C/2021 A1 (Leonard) might become bright enough to be visible to the unaided eye, after having spent tens of thousands of years approaching the inner solar system. On the 17th Comet Leonard will appear near Venus. There are other comets in the sky as well, but they are not expected to become very bright. Ceres, the largest object in the Asteroid Belt, will be visible using binoculars in the constellation Taurus. It was the first asteroid discovered, January 1, 1801, and could harbor extraterrestrial life.

There are several annual meteor showers, mostly weak, with only a handful of meteors per hour on average, or even fewer. Some but not all of the showers potentially visible now are listed below, based on David H Levy’s The Sky: A User’s Guide, the American Meteor Society’s website (see below), and other guides. The Southern Taurids already peaked, but can be seen until December 2nd; they are relatively slow-moving and often form bright fireballs. The Northern Taurids are also supposed to end December 2nd. Meteor showers are named for the constellation they appear to radiate from, in this case Taurus, but they can be seen looking elsewhere in the sky. The Leonids are visible November 3rd to December 2nd, peaking November 18th, and these meteors have the greatest speed of any annual shower. Andromedids appear occasionally but not every December and the AMS says this shower ends December 2nd. The Monocerotids can be seen until December 26th, peaking on the 11th. The Geminids are supposed to be the strongest meteor shower of the year, visible December 4th – 17th peaking early on the 14th. The Geminid and Leonid showers are strongest, especially the Geminids, but the Moon and light pollution can lower the count even if it is a clear. Showers can vary in strength and some occasionally produce extraordinary storms of meteors. There is a Leonid storm every 33 years. The Ursids are visible December 17th – 26th and peak on the 22nd. The Coma Berenicids are visible until December 23rd and peak December 15th. The Quadrantids, named for Quadrans Muralis a superseded constellation bordering the Big Dipper or Ursa Major in the north, are visible December 28th – January 7th and peak briefly on January 3rd. Some years I’ve tried to see all of the main showers. 

Satellites and sometimes larger objects, such as the very bright International Space Station, can be seen passing slowly overhead (some of the websites below give the dates and times when the ISS and other objects transit over the area). It is easy to see satellites early in the night and in the pre-dawn hours, when they are bathed in sunlight while we are in shadow. Huge numbers of satellites, mainly “constellations” of communications satellites, are being sent into low Earth orbit now, a growing problem for astronomers and other satellites.

Some of Parkwood’s green areas are good places for stargazing, but are closed at night, though I suggested to  the Parkwood Association that it would be good to have places to look at the sky. There are also more streetlights, but it is possible to request that they be better shielded or removed altogether ( the contacts were listed in the Association’s newsletter a few years ago). Despite streetlights the areas around Revere and Seaton roads; places along Highway 54, such as the watershed between Northeast and Crooked creeks, topped by Barbee Road; large ponds and lakes; and possibly Southpoint Mall, despite all of its lights, have good views down towards the horizon. The Jordan Lake Wildlife Observation Site off Martha’s Chapel Road and the nearby gamelands don’t seem to have closing times and state parks are open all night for campers. CHAOS, the Chapel Hill Astronomical and Observational Society, organizes local events and trips to darker locations and Morehead Planetarium at UNC hosts events.

55-Hopson and MLK rezoning hearings at the planning commission tonight

Tonight (October 12th) at 5:30 the Planning Commission will hear two rezoning requests in the Northeast Creek basin, a large Industrial Light project proposed along the edge of the County around the intersection of Highway 55 and Hopson Road and apartments at the northeast corner of Fayetteville Road and Martin Luther King Jr Parkway.  I have been paying the most attention to the 55-Hopson proposal, but I did not realize its full significance until a few days ago, so this post is at the last minute.  Tonight is not the final hearing.  There are or have been some other rezoning requests along the Creek this year.  This will be an online meeting through Zoom; registration is at:

zoom.us/webinar/register/WN_Az71ESRRSPumnJMjRXPEMg

More information about participating:

I wrote about this and some other proposals earlier in the year at:

www.northeastcreek.org/wordpress/where-the-red-fire-pink-blows-and-other-campions-in-the-triangle/

After the Planning Commission there would be a hearing before the City Council.  Below are some comments.  

Hopson-55 rezoning 

The staff report incorrectly said this site is in the Neuse River basin, but I think this is being corrected to the Haw and ultimately Cape Fear basin.  Legal definitions must be being used at the bottom of page 4, because there are obviously plants, animals, communities, and ecosystems on the site, since it is a location on the living Earth (though after mass grading the site would like more like a tract on a lifeless celestial body).  It is very easy to not find any rare or protected species or historical relevance.   The report lists many items that might be good to have in the planning process, but then they are rendered useless by saying that they do not apply in the absence of a development plan.

There are references to extending Hopson Road west of 55 on page 32, etc.  The rezoning request only covers part of the area discussed at the community meeting, but obviously the applicant must intend to build in the entire area, looking at page 34, etc.   The clearcutting over the last 10 years from 55 to Grandale leads me to suspect that all of this land is being sold, so does the applicant have plans or know something the public doesn’t know?  It’s possible the logging was done so they could then say on page 53 that the communities discussed in the NC Natural Heritage Program reports no longer exist, and without committed elements there are no guarantees about where building would be done on the site.  The area north of the powerline was also clearcut, but they say it will not be built upon.  When was there a hearing on building a new connecting road from 55 to Grandale?  I also heard a rumor late last week that the DOT wants to enlarge Grandale.  I have since been informed that the Durham-Chapel Hill-Carrboro Comprehensive Transportation Plan calls for a “major thoroughfare” from the Hopson and 55 intersection to Grandale, but nothing is listed in the State Transportation Improvement Program from now to 2033.  The NC NHP repeatedly surveyed the public lands along Northeast Creek immediately bordering the proposed rezoning site and recommends that new utility easements not be built (Jordan Lake Inventory 1999) and that “Preservation of upland buffers along the edges of the bottomlands should be given a high priority” (Durham County Inventory 1995).  It seems like building a major new road would have a worse impact on the environment than new utillity easements and there is already a lot of roadkill on Grandale Road around the bridge over Northeast Creek as it is, especially in late spring/early summer.  When was or will the public given an opportunity to comment on road plans?  How much blasting would have to be done to extend Hopson, given that it currently ends at a steep slope, on one of the highest hills in the area?  Will the DOT then want to extend a road across one of the wildest parts of Northeast Creek and the Tobacco Trail to 751?  There is already a connecting route from 55 to Grandale, made harder to use when the intersection was moved north, and the area around the old claypit can be accessed from the existing road.

As I said before, the application includes very little information about what is actually planned.  At the community meeting (see page 41) they said the plan was for office-type biomedical buildings, but Industrial Light allows many applications, including recycling centers, warehouses, freight facilities, junkyards, wholesale, etc.  It is possible a junkyard would actually be more environmentally benign than office buildings, parking lots, and lawn.  Freight or recycling would probably increase roadkill and litter and have other impacts.  What would be done to limit harmful chemical releases?  Would the buildings be built where they would have maximum impact on the adjacent gamelands, and Parkwood and Audubon Park would also be impacted since they aren’t that far away? 

What about the impact on hunting?  If hunting is limited by building, there could be over-population of deer in Parkwood.  Wildlife such as turkeys, wood ducks, prothonotary warblers, beavers (a subject of concern east of Parkwood this year), and possibly otters live adjacent to this site, while further away I saw a breeding female chuck-will’s-widow or whippoorwill, and I thought such birds had been driving out of the Triangle, like bobwhites.  

Would IL zoning allow greenhouses, under research?  I live miles from TW Alexander Drive, but I am already impacted by the light pollution from large greenhouses there, along with the new blue-white streetlights installed this year.  It is less obvious, but I can probably see light pollution from the Southpoint Mall area as well.  Light pollution is very obvious when there are low clouds, such as last weekend, but it reflects off dust, etc, and muddies the sky even on clear nights, so the Milky Way, which should be easy to see is barely if at all visible.  Closer to the site buildings and parking lots would no doubt be lit all night and there would probably be light trespass from poorly shielded lights into the gameland.  If a large greenhouse were built close to Parkwood it would probably be very bright on nearby streets when it is cloudy, and during the winter, even though there is a forested buffer, as happens at the Stonesthrow Apartments, by Burdens Creek.

What about the scientific significance of the claypit?  I can’t remember the details now, but I think paleontologists at local universities have excavated significant fossils there.  I have found plant fossils elsewhere where the sedimentary bedrock has been exposed a few miles away.  The application says there are not any steep slopes or wetlands, but is this true of the entire area they want to build on, from 55 to near Grandale Road?  The aerial photos show water in the old claypit and there are marshes in places under the powerlines, while it seems likely that there would be steep slopes around the claypit and 55.   

There is a small cemetery southeast of the claypit by the road and it is likely that there are archaeological remains where ancient people could overlook the floodplain and watch for game.  There is an old road of some near 55, but I don’t know of any ruins there.    

Even though there is preserved land, development nearby could still cause local extinctions, for example if species are bothered by light, noise, or water pollution; needed the upland habitat on private land as well as the public bottomlands; if they need a larger area of forest than just what is preserved; or if they are harmed by non-native species such as cats, dogs, Norway rats, or English ivy that could come with increased human activity.  

Some but not all of the woods in this area were clearcut over the past 10 years, but young trees have since grown back and species such as deer and red-tailed hawks have probably benefitted, and bobwhites might also like such habitat. Unlike what the application says, when I would go by over 10 years ago it seemed like the claypit was surrounded by forest, though it was relatively young, and some remains.

Apparently tree planting is a significant way to reduce the amount of carbon dioxide in the atmosphere, as the City of Durham supposedly desires, but Durham probably has fewer trees now than it did in 1995, at least in this section (though the amount of forest is probably greater than when agriculture was more prominent in Durham).  Building a new road, instead of using what already exists, and relying on cars, would also contribute to climate change.

I’m not necessarily against building something and I actually find new construction interesting, but very little information is being offered, what would this project mean for nearby “vacant” land, and suddenly there is talk of a new connecting road and expanding Grandale. I am generally against making Grandale a major road and there is already too much roadkill and dangerous conditions for pedestrians and cyclists along Grandale and on Scott King Road, where an elementary school is planned. The speed limit is high, and people speed, coming on to the curved and narrow bridge over the Creek, at one time a one-lane wooden bridge on a long gravel road.  Increased traffic might potentially drive off the huge numbers of  turkey and black vultures that sometimes roost, though it might increase their food supply. The only benefit is that the risk of people being harassed by over-zealous neighborhood watch types and even deputies while doing legal activities might be reduced, as well as illegal dumping, though littering might increase. It might be good to have better parking by the bridge. On the other hand, given that people like or liked to joyride ATVs in the area, including on the site in question, and it borders parkland, maybe it would become Durham’s next Ellis Research Center (on the south side of Ellis Road east of 147), which has private metal signs saying “No Stopping, No Standing, No Parking” along a public road, which reflects badly on Durham and is a threat to the public.

518 Martin Luther King Jr Parkway

I am not very familiar with this site except passing by, but it is in the headwaters of Northeast Creek’s north branch and it would be good if woods were preserved, especially along the roads, the Tobacco Trail, and any streams; native plants used in landscaping; light pollution limited, etc. The woods might not be very old, but a rare pink ladyslipper orchid grew in young pinewoods where Woodcroft Parkway was extended across Fayetteville and some species prefer young or otherwise piney woods. There is already a lot of traffic at the intersection to consider and the ATT has crossings in the area. If there are steep slopes, people might throw their trash over the edge if it is made convenient and without consequences for them. It is good that the applicants say they will preserve some existing trees and include a park, though these probably aren’t binding commitments and it would be good to keep the trees along the roads. The maps show a hill on the site and it might have a good view if cleared, as did the ridge at 54 and Barbee Road, which is the watershed separating the Northeast Creek and Crooked Creek basins.  This area has also become much more densely built-up in recent years, but much of it is in the Third Fork and Crooked creek basins. 

Where the red fire pink blows and other campions in the Triangle

Fire pinks seem to be very rare wildflowers in and around the Northeast Creek basin and possibly throughout the Triangle. I have only come across these bright red flowers with five deeply notched “pink” type petals at two locations in southern Durham County, on the edge of RTP. Fire pinks were the North Carolina Botanical Garden’s 2015 Wildflower of the Year, and free seeds were offered at the time ( ncbg.unc.edu/plants/nc-wildflower-of-the-year/ ; this year’s plant is the American beautyberry), so some might grow near the visitor center, but I haven’t seen them there myself. The first time I came across one of these unusual flowers might have been in May or possibly June off of South Alston not far from the border with Wake County, between the basins of tributaries Burdens Creek and Kit Creek. It might have been on a Sunday morning in late May 2001, also memorable because Sheriff deputies had a roadblock up the road, though there wasn’t much traffic. I stepped off the road along a rocky brook I think of as azalea brook in a somewhat open forest of pines and deciduous trees with sort of ‘dry’ soil where abandoned farmland was reverting back to forest on a late spring/early summer morning. I was familiar with the area because my Dad used to unicycle on a curcuit through the area on Saturday mornings and I sometimes joined by bicycle. The brook flows over slabs of solid bedrock, and the unusual igneous rock intrusions in the area might be the reason fire pinks and other rare flowers have grown there. On a high bank above a sharp bend there was an unusual wildflower maybe 1 to 3 feet high, probably bent over, with sparse leaves and striking red flowers that were sticky on the outside. On another occasion, maybe in the summer, I saw a single small fire pink on the edge of lawn on So Hi Drive near the Creek (maybe this was actually the first one I saw). Several years ago many fire pinks grew in a ditch at the edge of the woods across “Solutions Drive,” former South Alston, from what is now the back gate of the Social Security Administration’s secretive printing facility at 3604 Louis Stephens Drive, but more recently I have only seen yellow Jerusalem artichokes there (native flowers, despite the name). Wildflowers of North Carolina (Second Edition) calls fire pinks “weak perennials” and individual plants don’t seem to live very long. I went back to see the first plant I mentioned one or a few years later and there was no sign of it. I haven’t seen a fire pink in many years; possibly I haven’t been in the right habitat in the right season, but I think they must really be rare or I would come across them more often. They seem to prefer well-drained possibly poor soil with at least part-sun, and being shaded out by trees might be one reason individuals don’t live very long. They might benefit from periodic burning so they can get more sunlight.

Fire pinks (it seems like they could be called firepinks, but at most guides just hyphenate the name), also called Indian pinks and red or scarlet catchflies, are in the pink, campion, or carnation family (the Caryophyllaceae), as is star chickweed, a somewhat common early spring woodland wildflower, and several other sometimes showy flowers that should be found in the Triangle, though I haven’t encountered them myself. Like carnations and other pinks, fire pinks have opposite (paired) leaves and the stems are swollen at these nodes. The leaves are rounded and without serrations and when not in flower the plant is a clump of basal leaves. Fire pinks and related flowers often have a swollen calyx (the green sepals around the base of a flower) to varying degrees. Pink refers to their deeply notched petals, sometimes so deeply notched that they appear to have many petals, as is the case with star chickweed, not to their sometimes pink or red colors. “Pink” probably relates to pinking, as in pinking shears, scissors that make a zigzag cut in cloth, similar to the petal shape of many pinks. Catchfly refers to the stickiness of many of these species, not always around the flowers.

Fire pink’s scientific name is Silene virginica; it is unclear whether the generic name Silene refers to the Greek mythological figure Silenus, chief of the woodland satyrs and foster father and teacher of Dionysus, the god of wine, or to saliva (sialon in Greek), because of the stickiness. Both interpretations could be correct. The eFloras website says these flowers were or are called seilenos in Greek, possibly because Silenus got drunk and foaming. All About Alabama Wildflowers, an informative book that covers propagating and growing many wildflowers, compares distinctive projections low on the petals to hooves, satyrs sometimes sometimes being described as hooved. Both the genus and this species were named by Carl Linnaeus.

There are several species of native and introduced Silene in North Carolina, as well as less closely related flowers. Silene that might be found in the Triangle include the starry campion, also called star silene or widow’s frill (S. stellata); bladder campion or maiden’s-tears (S. cucubalus); sleepy catchfly (S. antirrhina); wild pink (S. caroliniana; it can hybridize with the fire pink); and night-flowering catchfly or sticky cockle (S. noctiflora). None are bright red, but in the Midwest royal catchfly, also called wild pink (S. regia), is another bright red Silene, and there are related flowers in the West that have been called Indian or fire pinks. Non-native bladder campions are named for their very enlarged calyx, and have also been called bird’s-eggs, fairy-potatoes, and rattle-bags. Also in the Triangle there might be non-native corn-cockles (Agrostemma githago) and mullein pink or dusty-miller (Lychnis coronaria). Lychnis comes from the Greek for flame, lamp, or light, another fiery color reference. White campion, also called evening lychnis or white cockle (L. alba), can be found elsewhere in the Carolinas. Species of Lychnis and Silene are very similar and are sometimes classified in one genus. There could also be soapwort or bouncing bet (Saponaria officinalis), both names related to how it produces a soapy lather in water (bouncing bets were washerwomen).

There are many related native and non-native chickweeds, in more than one genus, and while they are probably best known as household weeds star chickweed is a bright white wildflower blooming in older woodlands along Northeast Creek around now, and stands out as the forest floor is cast into shade later this month. Its scientific name is Stellaria pubera; the generic name refers to stars and the specific name might refer to its minute fuzziness or puberulence. It is also called giant or great chickweed, wood starwort (some other chickweeds are also called starworts), winterweed, and birdseed and has five petals, but they are so deeply notched that five seems to be ten. Introduced common chickweed or starwort, S. media, is eaten by chickens and other birds (and so it has been called “the hen’s inheritance,” according to A Sampler of Wayside Herbs), and there is grass-leaf chickweed, also called lesser or common stitchwort, S. graminea, another non-native, as well as native and non-native mouse-ear chickweeds in the genus Cerastium.

Related Dianthus, such as carnations (D. caryophyllus), sweet william (D. barbatus), and the (garden) pink (D. plumarius) are common ornamental relatives from the Old World with many cultural associations around the world, including with International Workers’ Day (May 1st, labor day in many countries), International Women’s Day (March 8th), Mother’s Day (May 9th this year), both weddings and funerals, and carnations are one of January’s birth flowers. Sweet william and pinks grow wild in parts of the Carolinas, and Deptford pinks or grass pinks (D. armeria), another European introduction, can be found in the Triangle, according to the Manual of the Vascular Flora of the Carolinas. D. superbus, native from Europe to Japan, is called nadeshiko in Japanese, and Yamato nadeshiko refers to Japan’s traditional feminine ideal (Yamato is one of the many old names for Japan) and the national women’s soccer team is nicknamed Nadeshiko Japan.

A fire pink flower has five petals (with distinctive projections around the flower’s green throat), five sepals, ten male stamens, three female styles, and the deep tubular throat of the flower is ribbed longitudinally. The flowers are arranged in a wide and loose cluster called a cyme, in which the center flowers open first, and a fire pink probably has blooms over several weeks, producing flowers and ripe seedheads at the same time. Each flower can yield several brown seeds, in a bell-shaped capsule with six teeth at the top. There doesn’t seem to be any special means to spread the seeds, yet they seemed to spread far along that stretch of South Alston in only a few years, though there might have been more plants than I knew about.

According to Wildflowers of North Carolina, fire pinks can bloom April – July. The Illinois Wildflowers website ( www.illinoiswildflowers.info/woodland/plants/firepink.htm ) hypothesizes that they are pollinated by ruby-throated hummingbirds and larger butterflies, which would make sense given their bright red color and tubular shape. It seems surprising that these relatively small flowers growing in dry soil would produce enough nectar to satisfy a hummingbird. The stickiness should deter ants and other insects from stealing the nectar without transferring pollen, as well as deterring pests. Bees can steal nectar by biting through the sides of flowers, such as morning glories and probably also coral honeysuckles, another red spring and summer flower, but fire pinks might be toughened against this. A Field Book of American Wild Flowers (first printed in 1902) says white starry campions attract clouded sulphurs, a medium-sized yellow butterfly, and moths. Some related campions, such as night-flowering catchfly and white campion, as well as soapwort, are stark white and fragrant, to attract moths, specifically including sphinx moths in the case of soapwort (according to A Naturalist’s Guide to Field Plants).

Fire pink flowers have both male and female parts (a perfect flower), but other Silene species have been used in the study of the genetic determination of sex in plants (and they have sex chromosomes similar to our own, though the phenotypic results can be much more complex than just producing male or female flowers) and they suffer from a sexually transmitted fungal disease that causes sterility. Some species of Silene also have exceptionally large or even the largest known mitochondrial genomes (these genes control a eukaryotic cell’s powerplants, the mitochondria, which might have originally been free-living prokaryotic cells).

I haven’t come across any information about herbivores of fire pinks. There are also seemingly few recorded cultural uses or associations with fire pinks. Fire pinks were apparently considered poisonous by some Indian groups, possibly because fire pinks were conflated with pink-root (Spigelia marilandica), also called Indian pink, a five-petalled red and cream-colored flower related to the early spring-blooming and poisonous (if eaten) yellow jessamine vine, South Carolina’s state flower. Pink-root and possibly fire pink were used to drive out intestinal worms. For some reason starry campion was once used to treat copperhead and rattlesnake bites, but this treatment has long been called useless. Old World campions, including bladder campion, were thought to have the power to stun scorpions and neutralize their stings, and maybe this idea was transferred to snakes. The leaves of both bladder campion and chickweeds can be eaten after boiling (some chickweeds are eaten raw). Reportedly people on the Spanish Mediterranean island of Minorca lived on bladder campion after locusts consumed their crops. Chickweed is or was even considered “a delicacy” in Europe, sold in markets and substituted for spinach (according to Wildflowers of the Blue Ridge Parkway). Several of these plants contain saponins, ranging from a poisonous level in soapwort to just adding a little bitterness in bladder campion. Saponins are surfactants and soapwort really can be used for cleaning, and has been called fuller’s herb for its use in the fulling (cleaning and thickening) of wool cloth.

The reason to think about fire pinks early this spring is because three rezoning requests will probably be coming up near where fire pinks have been found. First, a few years ago Durham County bought the large flat field bordered by NC 55, TW Alexander Drive, and two stubs of what was South Alston, “Solutions Drive” and “Experiment Drive.” Until about 13 years ago this was a large hill covered with a young pine forest; a house near the top had a commanding view up and down 55, with a few mimosas, sumacs, black locusts, or the like and winged elms over grass and herbs down to the highway, while blackberries bloomed along TW Alexander in April. The hill was blasted away day and night, reportedly trucked away as fill for NC’s first modern toll road and whatever was left was deposited in the abandoned claypit a short distance southwest across 55, on what was the continuation of South Alston into Wake County. I remember hearing it from miles away on balmy late spring or early summer evenings. When I went by the corner in late May it had already been mostly levelled, with a whitish or pale cliff at the south end. I think they were reported to the police several times for noise heard further west. Blasting the igneous and sedimentary innards of the hill might have rattled the County’s Triangle Wastewater Treatment Plant, across 55 and dumping into Northeast Creek. There were plans for residential construction or a commercial strip mall at the corner, shown on some maps, but nothing was ever built. The site, about 40 acres, is addressed as 451 TW Alexander, 6001 NC 55, and 6026 Experiment Drive, probably where the farm’s driveway was (these parcels can be searched for through Durham’s Interactive Maps durhamnc.gov/1455/Interactive-Maps ). I thought management at the Triangle Wastewater Treatment Plant wanted the land for a sludge-drying facility, a valuable feature the plant currently lacks, but a community virtual meeting February 18th was about rezoning the site to Office and Industrial (from residential, commercial, and office zonings) for “a new Durham County Public Works Administration Building.” I was the only person who ‘attended’ the meeting. The presenters gave basically no information beyond what was in the brief Planning Department announcement about the meeting. I said what needed to be said, but I had a feeling that I had been insulted and there seemed to be little point to the meeting. Based on the very little that was said, I don’t have an objection to building an office building, but as I said then, it would be good if the landscaping fit with the unique features of the site, or if wildflowers were allowed to colonize the site naturally, and it seems likely that an office building wouldn’t take up all of the land. I haven’t seen any fire pinks at the site, but they could be there. Buttercups and probably Lespedeza or bush clover are abundant in the field and woodland spring ephemerals are currently blooming along a rock-lined stream I could call cane stream. The field used to be mown periodically, but even after that ended trees have been slow to return, and probably little real soil was left after the hill and its topsoil was carried away.

Business interests want to rezone a vast area of Triangle Brick Company land a short distance south of the above site, extending from the east side off 55, just south of the intersection of the new Hopson Road and 55, through the abandoned claypit off Greenlevel Church Road (formerly South Alston), as far west as the top of the ridge that can be seen from the Grandale Road bridge over Northeast Creek, a site that could be in all more than a mile across. Some of the land might not be in Durham County, but I think the proposal calls for building only in Durham. I’m suspicious about what such a project would mean for the land owned by the Wrenn family further west, along Grandale and Wake roads. Both of these vast areas were clearcut, the Triangle Brick Co.’s land around summer 2010 and the Wrenn land maybe in 2018 or before. The land immediately around Northeast Creek is owned by the Federal government and managed by the NC Wildlife Resources Commission as gameland and on the west side of 55 a large area is owned by Durham County. I think I was one of only two community members ‘attending’ the virtual meeting on January 26th, but the well-known lawyer Patrick Byker, the main presenter, must not have known I was there. I think the figure given was that this “assemblage” is in all 241 acres, and they want it all rezoned Light Industrial (some of it is currently Rural Residential) and annexed by the City of Durham, to build a business park with five to six short office or industrial buildings (similar to those built recently at the corner of Hopson and 54, I think it was said by the same company), with construction in stages, starting in the spring of 2022. These low-lying gamelands are NC Natural Heritage Program inventory sites, and this discouraged residential construction on Scott King Road near the Tobacco Trail about ten years ago (but a DPS elementary school will soon be built at the “Scott Mill” site). The bottomlands periodically inundated by Jordan Lake for flood control are protected as public lands, but species living on the protected land could be lost if they also need the surrounding rural uplands to live or if they require a larger habitat than just what is preserved on the government lands. A stark example is provided by two very large woodpeckers. Pileated woodpeckers don’t seem to like built up areas, but I often hear their calls along Northeast Creek and elsewhere in the Triangle and occasionally see one, while ivory-billed woodpeckers, which are much larger but similar in appearance, are now more like rumors or apparitions than living birds and might be completely extinct. The related Cuban ivory-billed woodpecker, a subspecies or a separate species, might also be extinct, as might the related imperial woodpecker of Mexico, apparently the largest woodpecker in the world if it still exists. I saw something like a breeding chuck-will’s-widow or whippoorwill in a scrap of woods at the school site on Scott King Road, rural birds that I thought had been driven out of the region (the bird, I assume a hen, was obviously trying to lead me away from a nest or chicks hidden nearby). The NHP inventory reports note nesting black-and-white warblers and probably nesting sharp-shinned hawks and the presence of ribbon snakes as rare animal species in the area, as well as Douglass’ bittercress and other state or regionally rare or unusual plants, and there were otters and mink along the Creek, but the area hasn’t been surveyed since 1999. The most recent Durham report recommends that “Preservation of upland buffers along the edges of the bottomlands should be given a high priority. These slopes provide denning areas for terrestrial species, as well as refuges during periods of high water” while the 1999 Jordan Lake Inventory recommends that “No more utility corridors should be allowed in the area” along Northeast Creek between 55 and 751, and a project south of the Creek there would probably require new Durham water and sewer connections and lift stations to get over the hills, and maybe new electrical infrastructure as well. I think there was discussion of building a utility easement through here for 751 South at one point and earlier there was discussion of a road extension.

Lastly, during this economic crisis there is a rezoning proposal at the intersection of Northeast Creek Parkway and So Hi Drive (2102 So Hi Drive, on the south, RTP side of the intersection), near the Triangle Curling Club building and extending towards the intersection of Northeast Creek Parkway and East Cornwallis Road. Northeast Creek flows through this large, long undisturbed wooded site and the site also includes a small amount of land on the north side of the Parkway. It is owned by Parmer Woodlands 3 LLC, with an address in Carlsbad, California. Similarly named LLCs with the same address own much of the north end of RTP and March 23rd there was a Board of Adjustment hearing over rear parking lot landscaping at a very large project already being built a short distance beyond the Creek, but hidden by the forest (it has the addresses 2152 and 2362 So Hi Drive and 224 Northeast Creek Parkway, but doesn’t seem to connect, at least for now). I must have been the only person ‘attending’ the community meeting, which was also the evening of February 18th. They want the site rezoned as Science Research Park, from Rural Residential, to build two office buildings, but it was not entirely clear if the proposal is to build along the road, so Northeast Creek wouldn’t be crossed. I have seen many locally rare plants nearby, including horsetails, liverwort (the non-flowering plant), toothworts, Hepatica (a pale blue early spring flower sometimes called liverleaf or liverwort), star chickweed, at least one large Catawba Rhododendron (it is unclear if someone planted it long ago or if it really is the last of its kind along Northeast Creek, and a few years ago it was narrowly missed by a logging road), serviceberries (probably done blooming by now; their fruit is apparently a favorite food of chuck-will’s-widows), spicebushes, Penstemons, and umbrellatrees, deciduous magnolias with huge leaves that usually bloom by the start of May. Umbrellatrees seem to be much more common in Wake County than west, and perhaps fire pinks are also more common in the Neuse River basin. There are numerous beaver ponds, some visible from Northeast Creek Parkway near Cornwallis. These two ends of RTP where fire pinks grow (or grew) are also some of the few places where there are pinxterflowers, deciduous native azaleas a bit more common than fire pinks, with elegant honeysuckle-like nearly white to light pink or purple, fragrant flowers in late April, another sight to see before the Silene’s fiery red as summer’s heat begins.

Rainer and West in Planting in a Post-Wild World write:

…[A] new way of thinking is emerging. It does not seek nature in the remote mountain tops but finds it instead in the midst of our cities and suburbs. It looks at our degraded built landscapes with unjaded eyes, seeing the archipelago of leftover land—suburban yards, utility easements, parking lots, road right-of-ways, and municipal drainage channels—not as useless remnants but as territories of vast potential. We pass them every day; their ordinariness is what makes them special. As such, they are embedded in the fabric of our lives, shaping our most recurring image of nature.

The traditional landscaping that we inherited from the early gentlemen and merchants and their gardens evolved into landscape culture of “naturalness” as the picturesque preference for long views, open landscapes, clean edges, and touches of mystery. As a result, the general public has little tolerance for wild, illegible landscapes and plantings, especially in cities and towns. When people encounter highly mixed plantings, they are often reminded of abandoned fields or derelict industrial sites, places often associated with urban decay or neglect.

Rainer and West give us an alternative vision that can begin with our yards and be adapted to our communities.

So what exactly is the planting of the future? Look no further than just outside your front door. Go find a patch of weeds in your neighborhood. Notice the variety of species and how they interweave to form a dense carpet. Or better yet, take a hike in a nearby natural area. Look closely at how plants grow in a meadow or a forest’s edge. Observe the lack of bare soil and the variety of ways plants adapt to their site. Then when you get back to your neighborhood, compare those wild communities to the plantings in landscape or garden beds. There is a difference between the way they grow in the wild and the way they grow in our gardens. Understanding this difference is the key to transforming your planting.

…the solution lies in understanding plantings as communities of species that cover the ground in interlocking layers.

Notice that the question for gardeners shifts from what to plant to how to plant.

By focusing on naturally occurring plant communities, as opposed to those that are purely native, the focus is shifted from a plant’s country of origin to its performance and adaptibility.

All it takes to become a plant community is:

1. All plants should survive in similar environmental conditions.

2. Plants must be compatible in terms of their competitive strategies, the key to having plants that last.

The practice is to cover the ground densely by vertically layering plants. As the light levels drop under a tree, grasses transition to a mass of ferns, maintaining a continuous sea of plants. The bases of trees where traditional planting often piles mounds of mulch can be filled with plants (green mulch) instead. Any space around the base of a plant is a space waiting to be filled. Even low plants benefit from being under-planted with creeping plants.

Rainer and West talk about ” naturally occurring plant communities, as opposed to those that are purely native.” Doug Tallamy in Bringing Nature Home is an entomologist concerned about the insects that consume native plants and support native insectivores, like birds and amphibians. Tallamy goes to the ability of the native insects to survive on the plant, regardless of its origin but notes that even alien plants with similar origins accommodate fewer insect species than native plants. The ability of insects to survive to eat and pollinate the next year’s crops of native plants is critical to the survival of those native plants. As habitat is destroyed in development, as pesticides and herbicides are broadly applied without planning, the links between native plants, native insects, and native birds are broken and we start to notice population declines of birds and popular insects, like butterflies and showier moths. Tallamy describes these relationships in his chapter, “What does bird food look like?”

Whatever else it is, local habitat extinction is a local ecological and horticultural crisis. Having the native plants for native insects is the security for the habitat of the rest of the food web. And whatever impact native insects have on alien plants, alien insects frequently have had devastating impacts on native plants. And alien insects are frequently transported on alien plants.

How did we get so enamored of ornamental exotic species in the first place? Andrea Wulf tells the tale of how, on the British side of the Atlantic, wealthy gentlemen and merchants with networks of correspondents around the world traded plants from one continent to another. Andrea Wulf’s The Brother Gardeners describes how that correspondence and shipment of boxes of plants produced the explorer-botanists who would search out and ship the boxes of these new exotics as they were laying the foundations of the science of botany in the midst of Britain’s expansion of its empire. She then traces that history to the English obsession with gardening that was exported to America.

Peter Collinson had a correspondent in Pennsylvania named John Bartram, who regularly shipped him boxes of native plants from the eastern coast of America. Another correspondent, a Father d’Incarville sent seeds of Ailanthus altissima from China to Collinson in England in 1751; within a few decades, the tree of heaven had arrived in America. Because it is resistant to pollution, it was widely planted. Today it is considered an invasive species. In 1739 the Camellia japonica camellia had arrived in England and was on its way to America. It is one of the mainstays of ornamental exotics and quite well behaved; its popularity increased the replacement of native plants (such as rosemallow) with ever more camellias. In fact, the default landscaping for local gardens tends to be these exotics that are the result of 300 years of globalization.

Wulf’s book introduces some of the early scientific botanists, such as Mark Catesby, whose Natural History of Carolina, Florida, and the Bahama Islands, (London, 1731-48) contains some of the earliest paintings of native plants and animals in the Carolinas. She follows the obsession with gardens that spread from France to England to America; a subsequent work of Wulf’s describes the gardening obsessions of the four first US Presidents, to whom much of our current styles of landscaping owe inspiration.
