Other Statuses

Canadian Species at Risk Act (SARA) Schedule 1/Annexe 1 Status: T (05Jun2003)
Committee on the Status of Endangered Wildlife in Canada (COSEWIC): Special Concern (25Nov2011)
Comments on COSEWIC: This grass occurs in limited areas of remnant short-grass prairie in southern Saskatchewan and Manitoba. Threats to this species include coal strip mining, invasive alien plants and overgrowth by woody vegetation and high grass that were once controlled by bison grazing and fire. However, recent survey efforts have increased the known number of populations and it no longer qualifies as a threatened species.
Designated Special Concern in April 1998. Status re-examined and designated Threatened in November 2001. Status re-examined and designated Special Concern in November 2011.
