General Status Rank
Rank: 
Secure
Status Rank Description: 
Population size is poorly documented, but species appears to be abundant throughout its range. Habitat loss is unlikely to be a problem for this species in the NWT, however loss of wetlands could be problematic at the southern extent of the range.
