OTHER STATUS : 
The Montana Natural Heritage Program lists northern comandra as globally
secure (G4) but imperiled in Montana (S2) because of rarity or because
other factors make it vulnerable to extirpation [20].  The U.S.  Forest
Service classifies northern comandra as sensitive in Montana; it has
been located on the Flathead and Kootenai National Forests [31].

Northern comandra is included on Maine's list of Plant Species of
Special Concern [43] and is considered threatened in New Hampshire [40];
however, it is widespread in the Mahoosuc Range on the Maine-New
Hampshire border [29,40].  It is also threatened in New York and has
been assigned a state rank of S1 (critically imperiled in New York state
because of extreme rarity or is extremely vulnerable to extirpation from
New York State due to biological factors) [41,42].  Northern comandra
was known from a single site in Vermont, a tiny bog on Mt. Mansfield,
but has not been found since 1901 and is now presumed extirpated in that
state [40].
