The populations and habitats of many freshwater marshbirds are in decline. Several species are of conservation concern in the northeastern U.S. Adding to this is the fact that many wetland birds are detected so infrequently during surveys that there is a lack of useful data. The NHESP relies heavily on voluntary reports of rare marshbirds from birders. Documentation of these species helps NHESP monitor their status.
Rare marshbirds and their habitats are protected under MESA and the Wetlands Protection Act. Marshbird habitat may also be protected through land donation or purchase. Active management, like manipulating water levels or controlling exotic vegetation, improves these habitats.
