Virginia Wetlands Protects Rare Species, But Development Looms

Castanea Volume 82, Issue 2

This study and its publication come at a critical time for the Abrams Creek Wetlands. No other limestone-based wetland in the state has as many rare plant species.

Castanea— Natural wetlands provide safe haven for birds, support rare native plants and contain natural ecosystems that can only exist in fens, swamps and marshes. However, wetlands are regularly threatened by road, housing and farmland development. Determining the ecological value of a wetland—and deciding whether to protect it—often requires a thorough inventory and an examination of its supported species.

The authors of a study published in the current issue of Castanea inventoried the Abrams Creek Wetlands in northwestern Virginia’s Shenandoah Valley. The researchers examined what was currently responsible for the makeup and interactions of the Abrams Creek Wetlands natural communities and documented what could be lost if conservation did not accompany future development of the area.

The Abrams Creek Wetlands is surrounded by houses and farms, yet it retains its ecological significance, attracting birders and other naturalists. With soils that remain extremely high in calcium, it gives modern researchers an indication of the original ecology of the stream-valley wetlands in the area. Half of the wetlands have been designated as a preserve, and conservation efforts have elicited promises that the other half will be separated by a 50-foot buffer from the road with housing construction scheduled to begin in 2018.

The researchers found 304 species in the 24-hectare Abrams Creek Wetlands; 71 percent of which are native to Virginia. Those native species cover 72–99 percent of the marshes, fens and swamps that make up the…
