Marshes, Mires, and Shoreline Habitats
Coastal Freshwater and Low-Salinity Marshes
No image for this habitat.
General Description Members are associated with coastal marshes that are primarily freshwater but with some also occurring in brackish but not salt marshes. Members of this habitat are restricted to the Coastal Plain, with residential populations, at least, not occurring in the Piedmont or Mountains.

This habitat intersects Salt and Brackish Marshes, with both including low-salinity areas.

Nr = Number of Ranked Species = 25
Ner = Number of Extant, Ranked Species = 20
Nv = Number of Historic and Extirpated Species = 4
Nar = Number of Species at Risk of Extirpation (State rank > S5) = 17
Nss = Number of Secure Species (State Rank = S5) = 3
Pss = Proportion of Secure Species (Nss/Ner) = 0.15000
ENE = Expected Number of Extirpations (Sum of PE) = 0.89424
Average PE (ENE/Ner) = 0.04471
Habitat Risk Index = (Nar+Nv) x Average PE = 21 x 0.04471 = 0.93891
