Taxonomic Comments
As treated by Kartesz (1994 checklist), includes Poa languida (= FNA's Poa saltuensis ssp. languida), which many botanists (and most/all floras) treat separately. FNA (vol. 24, 2007) recognizes two distinct subspecies (saltuensis and languida).

Rank Reasons
Poa saltuensis is demonstrably widespread in Ontario and northern portions of its range.
Range Extent Comments
Maine to southern Ontario and Minnesota, south to Pennsylvania, Kentucky, and Iowa.
Occurrences Comments
Common to widespread in Ontario. [The following list of documented occurrences include records for both Poa saltuensis and P. languida. For states with both taxa, P. languida (Pl) records will follow P. saltuensis (Ps) records where the information was available.] Documented occurrences in Iowa (Pl: 2, plus 2 historical locations (H)), Illinois (Pl: 1, plus 2H), Indiana (Pl: 10 northern counties), Kentucky (Ps: 5--1B, 2C, 2E, plus 2H), Maryland (Pl: 1D), Michigan (Ps: 18 northern counties; Pl: 19 southern counties), Minnesota (Ps: 3 counties; Pl: 4 counties), New Hampshire (Ps: 4 counties), New Jersey (Pl: 2 counties), Ohio (Ps: 1C; Pl: 21--3A, 2B, 3C, 13U, plus 4H), Pennsylvania (Ps: 25 counties; Pl: 6--2B, 4E, plus 7H), Tennessee (Ps: 2; Pl: 3), Vermont (Ps: 8--1A, 1B, 1CD, 5E, plus 9H; Pl: 1), Virginia (Ps: 7--1B, 1BC, 1CD, 1D, 3U, plus 2H; Pl: 1CD), West Virginia (Ps: 1E, plus 7H).
Threat Impact Comments
Highly threatened by land-use conversion, habitat fragmentation, succession, and to a lesser degree by forest management practices (Southern Appalachian Species Viability Project 2002).
Ecology & Habitat

Habitat

Woods or forest borders with more affinity to semi-shaded to open, dry or rocky habitat, although occurs in dense forest (Indiana) and in wet locations, i.e. cedar swamps (Vermont), shores and dune regions (Michigan and Indiana).
