In the Northwest Territories, the Banks Island Alkali Grass has only been found growing near the shores of inland freshwater lakes at the southern part of Banks Island. Globally it is found in the NWT (3 sites), Alaska (1 site), and Nunavut (4 sites). This species was only recently identified after genetic analyses in 2008 confirmed this grass as a distinct diploid species from other arctic alkali grasses. It has not yet been ranked by NatureServe but certainly meets the G1 (critically imperiled) or G2 (imperiled) status.
This species has been ranked as May be at Risk by the NWT General Status Ranks process. This species has not gone through either national COSEWIC assessment or Species at Risk Act processes, nor any processes under the Species at Risk (NWT) Act.
