Threats

Threats

Cumulative threats from habitat loss and/or conversion to agriculture/urban development, invasive non-native species, climate change, livestock grazing, recreational use, etc. (as outlined in short and long-term trends) have all likely contributed to declines in bee abundance. The specific impact to each bee species is unknown due to lack of specimen data, surveys, natural history information of a species and analysis of these impacts on these variables.

Status Rank Description: 
Found in northern ecozones. Holarctic. Probably occurs in more abundance but there are too few data to figure out trends. Primarily a northern species, it's habitat is probably intact but climate change will/is having a large impact on this species. Only a handful of records.Nests attacked by Bombus hyperboreus; recent records from Fort Simpson area (Ragged Range Mulhalland Glacier)(Larter/Heron/Sheffield data). uncertaintly with regards to range extent and number of sites. - Found in northern ecozones. Holarctic. Probably occurs in more abundance but there are too few data to figure out trends. .
