Facts
Saltgrass is very widely distributed in North America, where it tolerates a wide range of habitat types. Wthin New England, saltgrass is restricted to coastal dunes and salt marshes.
Habitat
Marshes
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
