Did you know?
The largest rodents in North America, American beavers (Castor canadensis), commonly construct dams across marsh headwater streams. By damming these streams, beavers raise water levels and create a protective moat around their lodge; within the deepest waters of their impoundments, they store food for the winter. When the dam is breached and water slowly drains from the pond, wetland plants colonize the exposed edges; once the water drains enough to be limited to the old stream channel, the area that was once a beaver pond has cycled back into a marsh headwater stream.

State Ranking Justification [-]
There are several thousand occurrences statewide. Many documented occurrences have good viability and are protected on public land or private conservation land. This community has statewide distribution, and includes several high quality examples. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to development pressure or alteration to the natural hydrology.
