Conservancy functions preserve the quality and integrity of the natural and cultural environment of the Northeast Creek basin through research, conservation, preservation, and restoration.

What a Thirteen Years It Has Been

In February 2006, I and ten others gathered at the Grandale Road bridge over Northeast Creek to do stream monitoring and go on a hike to see spring ephemerals. Michael Pollock had a water sampling kit from City of Durham Stormwater Services, and after we tested samples from the west side of the bridge, led us on a hike.

Walking along the Corps of Engineers boundary trail on the south side of Northeast Creek, we saw trout lilies and foamflowers that had just begun blooming. Walking up the natural gas easement back to Grandale Road, we could look northwest across the creek valley to where the gas easement crossed Scott King Road.

In April we tested Northeast Creek at an accessible meander just north of Sedwick Road. And then we went for a hike to see the budding trees and the spring flowers. The red maples glowed pink; the oaks were light green; some of the trees had a bluish cast. Stepping along the soggy ground of the sewer easement was challenging, but the world of the Parkwood wetland that we were walking alongside offered more natural beauty to explore.

In May, we tested again at the Grandale Road bridge. This hike explored the east side of Grandale Road and up the powerline maintenance access road. Toward the top of that hill, we crossed over to the Northeast Creek stream channel, which we viewed from rock bluffs on the south edge of Parkwood.

I was hooked. Northeast Creek Streamwatch was the organization that understood what my wife and myself had seen in 1993 behind the Food Lion store on NC 55. We had seen a wetland with submerged trees and saplings. A great blue heron was perched on one of the saplings; a green heron perched on a slightly larger sapling nearby. That swamp has now become an open pond in flood times, most of the trees drowned. Beavers and property owners have re-engineered the water flow many times over the last 25 years. And I have become committed to preserving our Triassic Basin wetlands, their flora, and fauna for my grandchildren’s grandchildren’s grandchildren to be able to appreciate.

In the 13 years since then, the “we” that is the evolving association of people identifying with Northeast Creek Streamwatch have seen:
• Regular participation in the Parkwood Christmas Parade by puppets of a great blue heron, beavers, an opossum, and frogs.
• Spring and fall clean-ups of creeks that result in piles of dumped items for Durham Solid Waste to pick up the next week after Earth Day, Big Sweep or Creek Week.
• A class at Parkwood Elementary School about sand, clay, and silt and third graders planting and labeling native plants for a WaterWise garden.
• Library programs on the native plants of Northeast Creek and the techniques of rainwater harvesting.
• A kayak touring company that did trips up from the mouth of Northeast Creek at the NC 751 bridge almost to Panther Creek in Chatham County.
• Hikes along a Jurassic diabase dike formation to the ruins of Sears Mill, an old mill on Panther Creek.
• Testing at Northeast Creek crossing of Grandale Road, Sedwick Road, Ellis Road, and in Meridian Center.
• An umbrella magnolia by Northeast Creek at Ellis Road bridge.
• The descent of a source of Northeast Creek down a steep slope by the Durham Freeway as the creek crosses under the bridge on Glover Road, passes through a steep gully and crosses under the Durham Freeway.
• The seep behind an office near NC55 and Riddle Road that is one of the sources of the prong of Northeast Creek that flows just west of NC 55 down to Meridian Park.
• The runoff from US70 north of Miami Boulevard that flows through the parking lot of pawn shop and into woods into the back yards of folks on Peyton Avenue, yet another source of Northeast Creek; this tributary flows through Bethesda Park..
• A dump site adjacent to the creek of over 50 years duration that is grown up with red cedars, winged elm, and oodles of vines.
• Sandstone caves beneath a bluff supporting leatherwood.
• The wetlands at Ellis and So-Hi roads that extend through the RTP properties of major companies and warehouse complexes.
• The main stream of Northeast Creek in flood at the NC 54, Sedwick, and Grandale bridges.
• A crew from Hillside New Technology cleaning the litter from the blackberry growth next to the NC 54 bridge over Northeast Creek during Big Sweep.
• A mother who brought her son from their neighborhood in North Durham to participate in a clean-up of the creek that feeds Parkwood Lake because she wanted to teach him a service ethic.
• The awarding of Durham’s Distinguished Tree designation to a white ash in Parkwood and a scarlet oak on the Lowes Grove Middle School property near the creek.
• The effects of the 2007 drought at the mouth of Northeast Creek, the appearance of a prairie of grass mat strewn with large mussel shells.
• Snow and ice in the Parkwood wetlands in a picturesque meander that Durham Water and Sewer later repaired with a culvert..
• Neighbors and their acquaintances reporting sewer leaks and stormwater issues to us and we getting to see that they are indeed efficiently handled.
• The Creek Critters Puppets marching as the Krewe de Creek in the Durham Mardi Gras Parade and promoting the 2016 Durham Creek Week.
• The Monarch Caterpillar art project from Fayetteville Street Elementary School at the Monarch Festival along with the students that made it and their parents.
• The recognition as Durham Soil and Water Conservation District’s Urban Conservationist of the Year in 2016.
• The support of some 40 volunteers in the construction of Parkwood Village Association’s Wiggly Trail , erosion control, and native plant garden. Completing this project with volunteer labor and donations in-kind to match a $2500 City of Durham neighborhood improvement project grant.
• Continued collaboration with Parkwood Village Assocation, Parkwood Homeowners Association, Christus Victor Lutheran Church, Lowes Grove Middle School, Parkwood Elementary School, South Durham Regional Library, South Durham Farmers Market, and local scouts as well as many longstanding individual partners.

In the coming year the wildness will continue as we seek to grow participation in these initiatives:

Upstream Neighbors/Downstream Neighbors – The grassroots network of property owners and residents working on their own to conserve their own part of the Northeast Creek basin. Opportunities and tools to serve them are rainwater retention ideas, planting native plants, removing invasive plants, local creek clean-ups, adopting storm drains, adopting stream segments, adopting highways for cleaning litter. Citizen science activities include Audubon’s Backyard Bird Count, iNature.org, and many others. For additional citizen science opportunities, contact the NC Botanical Garden and the NC Museum of Natural Science.

Upstream Neighbors/Downstream Neighbors serves as a network to involve local schools and churches at the local level in local projects, which over the 47 square miles of the Northeast Creek basin means that seemingly small local efforts can result in large results on Lake Jordan’s quality just as small amounts of negligence have added up to a large excess nutrient problem for Lake Jordan.

Water Stewardship Network – The supporting network of schools, churches, government agencies, businesses, and voluntary associations that have an impact on Northeast Creek and ally with similar groups in other watersheds. These institutions support individual efforts as part of Upstream Neighbors/Downstream Neighbors. These are the locations of events, demonstration projects like gardens or rainwater treatments, and educational programs. They are Upstream Neighbors/Downstream Neighbors for their own property. Northeast Creek Streamwatch’s water stewardship network can tie into the North Carolina Watershed Stewardship Network (http://wsnet.renci.org/huc_report/index.html?huc=030300020605).

Creek Week and Big Sweep Events – The twice a year momentum builder for local efforts. They get people out into the stream environment and wetlands, show the natural beauty, and get something tangible accomplished with a very short commitment of time. This year’s Creek Week is March 17-23, 2019. Start planning local events for March 15 -23 and notifying colleen@northeastcreek.org.

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.

Save the Rain Workshop – Saturday, October 22, 9 am – 11 am

Upstream Neghbors/Downstream Neighbors Project hosts a Save the Rain Workshop

As homeowners, we can extend the principle of catching and holding rainwater to restrain how much water and how fast its flows downstream during a rainstorm. These actions can affect the amount of erosion of stream banks in downstream neighbors’ yards and reduce flooding of downstream neighbors’ property. We can also save back some of that water for dry spells, hold it long enough to recharge the water table here instead running rapidly the length of the Cape Fear River, and create more habitat for pollinators.

A reasonable goal is to capture the first inch of rainfall from the square feet that your property has as impervious surfaces and hold it for up to three days. There are a variety of ways to do this; the county Soil and Water Conservation District (in Chatham, Durham, and Wake counties for Northeast Creek) can provide technical assistance and tips for beginning your plan of rain saving. And you need not hit the goal of “one-inch saving for at least three days” all at once; you can try different combinations of techniques on your property to see what works best.

For the second year, Cory Quammen, a resident of Grandale Forest on the headwaters of “Tributary D” of Northeast Creek, is holding a gathering of his upstream and downstream neighbors, Saturday, October 22, 9am – 11am to show some examples of problems caused by excessive runoff as well as some rain-saving measures that have been installed on his property.. Invitations will go to the neighbors within his local creek basin in advance of the meeting. Contact cquammen@gmail.com for further information.

Upstream Neighbors/Downstream Neighbors Project holds Save the Rain workshop at South Regional Library on February 4, 2016

The Upstream Neighbors/ Downstream Neighbors project hosted Mike Dupree of the Durham County Soil and Water Conservation District at the South Regional Library on February 4. Mike informed us about the services that his department of county government provides to property owners and why these services benefit both the property owners and the quality of water—specifically in Northeast Creek and in Jordan Lake.

In introducing Mike, Cory Quammen shared how the Durham Soil and Water Conservation District is helping owners of property that backs up on a creek in his neighborhood with flooding and stormwater issues.

Mike will be speaking at the Eno River Unitarian/Universalist Fellowship (ERUUF) on Wednesday, February 24 at 7:00 pm. His topic will be managing water, nutrients, and pests.

Thanks to everyone who came to the South Regional Library. We would love to hear feedback from those of you (5) who set appointments for Mike to consult with you about the issues with your property. Send your comments to colleen_haithcock@yahoo.com.

For those who wish contact Mike Dupree, it is mdupree@dconc.gov or 919-560-0558.

Here is a link to a video about the Voluntary Nutrient Reduction Program that Mike Dupree described February 4.

Voluntary Nutrient Reduction Progam

Upstream Neighbors/Downstream Neighbors

Hurricane Joaquin highlighted the effect that upstream water retention has on downstream currents and flooding. It makes us more aware of being upstream neighbors of coastal areas like the Cape Fear region and also our immediate neighbors downstream.

The water that Joaquin dumped on our roofs and flowed down our gutters and downspouts and across our yards into tributaries of Northeast Creek will eventually join water that fell on roofs in Guilford County and flowed down the Haw River. Then it will collect the water that has fallen more recently on roofs in Sanford and Fayetteville before it reaches that bridge. The large area of the Cape Fear River drainage basin includes a lot of neighborhoods, with water flowing from upstream neighbors to downstream neighbors, affecting the use of water and the condition of the stream boundaries along the way.

Closer in, the water from Northeast Creek flows into Jordan Lake, which is the water supply for a number of neighborhoods as well as the towns of Cary and Morrisville. The Town of Cary in turn will supply additional water to the City of Durham during drought conditions.

More local, the water that runs off all at once from roofs, sidewalks, driveways, and streets (surfaces designed not to allow the water to soak in, called “impervious surfaces”) can erode downstream neighbors’ yards. The collecting of rapid runoff at creek junctions can back up into yards and threaten to flood under houses.

As homeowners, we can extend the principle of catching and holding rainwater to restrain how much water and how fast its flows downstream during a rainstorm. These actions can affect the amount of erosion of stream banks in downstream neighbors’ yards and reduce flooding of downstream neighbors’ property. We can also save back some of that water for dry spells, hold it long enough to recharge the water table here instead running rapidly the length of the Cape Fear River, and create more habitat for pollinators.

June Heavy Rains Affect Euclid Stream

The heavy rains and winds in late June caused some trees to be uprooted and branches to fall in the stream.

The new outfall construction just completed for the stream between the bamboo grove and the wetlands held up, although the straw and mesh was swept away in some areas.

Stream and bamboo cleanup

NECSW is actively participating in the volunteer effort to manage the Parkwood bamboo grove and clean up the Euclid stream. Our vision is to manage the bamboo grove to create a productive and esthetically pleasing public space. A healthy grove is uniquely beautiful, is a good habitat for birds, reduces rainwater runoff from surrounding land, and offers a pleasant parkland for walking and contemplation. Three of our members joined six other volunteers for several work sessions this past week.
