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 (HSS010).
