Abstract: | Bumble bees are important pollinators of native flowers and crop plants. Consequently, declines in bumble bee populations in many regions around the globe are cause for concern. We monitored abundance of 22 bumble bee species at multiple elevations over 5 years in Boulder County, Colorado. While no declines in abundance of any species were apparent over the course of the study, such a finding does not preclude prior declines in abundance. This study provides current baseline abundance data that can be used for future monitoring projects. |
