Living on the Edge
If you are lucky enough to live on property that backs up to a park or a stream, you are in the position of being able to enhance the value of the park or stream corridor by adding plants that support the ecosystem and that keep stormwater runoff from eroding the land and stream banks.
It is illegal to plant, mow, build, or do anything else to disturb the land within the park boundaries! Your help is invaluable in protecting these lands.
Enjoying your woods
Natural forests consist mostly of deep woods, and not of edges. But when we cut down trees for buildings or roads, we create a tremendous amount of edge, which is prime territory for invasive introduced plants. This is why we often see the edge of woods being swallowed by invasive vines. If you are the steward of that edge property, you can protect the woods by removing invasive plants and planting native plants to extend the benefits of the natural area.
What not to plant: Invasive introduced plants are problematic anywhere, as birds often carry their seeds into our natural areas, but it is particularly important to avoid using them right next to parks, where they can creep right in and take over. Examples include English Ivy, Japanese Pachysandra, Periwinkle, and many other groundcovers; some ornamental grasses such as Chinese Silvergrass (Miscanthus); vines such as Chinese Wisteria; trees such as Norway Maple and Callery Pear; and shrubs such as Japanese Barberry, Chinese Privet, and Burning Bush.

Great plants for forest edges
Forest edges often come with deer. Grasses and ferns are not bothered by deer, and taller shrubs and trees can be protected with wire fence-cloth cages until they grow high enough. Flowering perennials and short shrubs struggle, though, so listed here are perennials that are relatively unpalatable to deer, and shrubs that either grow tall or that are relatively deer resistant. All the listed plants can tolerate part shade and dry soil. For more details and additional options, search our native plant app.

Vines: Crossvine (Bignonia capreolata), Coral Honeysuckle (Lonicera sempervirens), Virgin’s Bower (Clematis virginiana)
Protecting our streams
Properties that include streams are the last bulwark against the damage inflicted by runoff from impervious surfaces. This “riparian buffer” captures and cleans stormwater runoff that can erode the banks and flood the streams. That floodwater carries tons of sediment down to the Chesapeake Bay, where it buries the sea grasses that are the basis of the ecosystem there. In addition, healthy streams need to be lined with trees to keep the water temperature cool and to provide leaves to feed the underwater ecosystem. The Commonwealth has a brochure on this subject.
Land-disturbing activities are prohibited within floodplains or within 100 feet of a stream, shore, or wetland, whether the land is publicly or privately owned, unless you obtain a permit. (“Land-disturbing” includes removal of vegetation and planting new plants.) Maps of these “Resource Protection Areas” can be found here. But if you need to restore lands that have already been disturbed, here are some plants that do well in that setting and that are found together in nature, again chosen with deer browsing in mind.
