Threats

Unknown; The species is found in numerous ecozones with differing scope, severity and timing of threats. Within areas of high human habitation, threats to bees centre around the loss of floral resources and nest sites. Cumulative threats include habitat conversion, increased pesticide use, invasive non-native species, fire suppression resulting in natural succession of otherwise open habitats (e.g., sand ecoystems, meadow habitats, etc), climate change (including increased drought), livestock overgrazing, etc. These threats may not applicable to portions of ecozones with large natural areas. Species specific threats are unstudied for most bees.
