Distribution

The minimum area polygon for this species based on locality records is approximately 190,000 km sq in the Northwest Territories. In addition, this species is widespread in the low arctic (Griffiths 1998). Range G was selected.
Score: 
G

Number of Occurrences

This species is known from 6 locality records in the Northwest Territories: Yellowknife (Griffiths 1998) Aklavik (Huckett 1965), 2 localities in the Tuktoyaktuk area, one locality in the Gwich’in Lands, one locality approximately 200 km north of Colville Lake (on Inuvialuit Lands),and Deline (localities inferred from distribution map (fig. 2252) in Griffiths (1998)). This species is also present in surrounding regions (YT, NU) (Griffiths 1998). As such, is likely more prevalent in the territory and a wide range was selected (6->300).

General Status Rank
Rank: 
Secure
Status Rank Description: 
A gap in the data is making this species appear vulnerable, when there is no indication that this is the case. Gaps in the taxonomic record do not represent real gaps and likely reflect a lack of collection effort, especially in the North. In addition, even though there are gaps in our knowledge of this species, it is likely more widespread in the territory, as it present in low arctic and boreal zones and in neighboring regions (Griffiths 1998). Therefore this species is unlikely to be vulnerable. Despite limited records (6), this species could be more prevalent than records would suggest (see range extent and occurrences). However there are gaps in information (Griffiths 1998). A conservative assessment would put this species at secure to apparently secure in the Northwest Territories, since although there is no indication that this species is under any threat, it is possible.
