Describe recovery strategies deemed necessary, based on the best available scientific and traditional information, to recover scarlet ammania populations in B.C., and recovery actions to achieve the goals and objectives. Scarlet ammannia (Ammannia robusta) was designated by COSEWIC as Endangered in April 1999 and confirmed in May 2001. It is listed as Endangered under Schedule 1 of the federal Species at Risk Act and ranked as S1 (critically imperilled) species in both B.C. and Ontario. In B.C., it is on the Ministry of Environment Red-list; in Ontario, it is listed as Endangered under Ontario?s Endangered Species Act 2007. Scarlet ammannia ranges from south-central B.C. south to Mexico, and eastward throughout central North America to Ohio and southwestern Ontario. It ranges south to the extreme southern U.S. and Mexico. The total number of populations in Canada has declined 40% over the last 50 years. In B.C., scarlet ammannia inhabits moist to wet, often alkaline, muddy shorelines of lagoons or ponds; sandy shorelines; or moist or dried alkaline flats. Ontario sites are on mudflats; sand beaches; wetland edges; dried-up pond bottoms; and moist, sandy depressions. Threats in B.C. include: habitat loss or degradation; changes in ecological dynamics or natural processes (flood regime); invasive species; cattle grazing, trampling and recreational vehicle activity are considered minor potential threats. Threats in Ontario include: changes in ecological dynamics or natural processes (flood regime and succession); invasive species and habitat loss or degradation. The recovery goal for scarlet ammannia is to protect and maintain the four extant populations in Ontario and the two extant populations in B.C., and to restore the species at historic sites if deemed necessary. Approaches to achieve these recovery objectives include: habitat protection, public outreach, inventory and monitoring, habitat management, scientific research and habitat restoration.
