State Ranking Justification [-]
Despite the fairly broad range of habitat Calamagrostis stricta occupies, there are only 13 verified occurrences in the state. Of these 13 extant locations, 4 are large and protected. There appears to be plenty of available habitat, so this grass species may have been overlooked. There are also 6 historical occurrences dating from the 1940s.
