Wetlands, Marshes and Swamps
Wetland habitats may also be found at other park units such as Malvern Hill, Gaines' Mill and Cold Harbor. These wetlands, in addition to their ability to harbor a diverse and unique community of plants and animals, provide several valuable ecosystem functions. Among these is their ability to filter sediment and pollutants from surface water runoff before it reaches associated creeks. This role is invaluable in the maintenance of water quality in the park's creeks, as well as downstream water systems. Because of the valuable roles that wetlands play in enhancing both biological diversity and water quality, the park works to protect these important natural features by maintaining vegetative buffers around them when possible, and by avoiding activities that may alter their hydrological regime.
