Michigan Bumble Bees

Multiple species of Bumble bees are in decline across Michigan, prompting appropriate conservation actions at the State and Federal Level. In 2016, Bombus terricola (Yellow Banded Bumble Bee) was listed in the USFW Service 7-year National Listing workplan, and in 2017 B. affinis (Rusty Patched Bumble Bee) was added to the Endangered Species list. Both species are listed as Species of Greatest Conservation Need (SGCN) in the Michigan Wildlife Action Plan. MNFI is actively engaged in the long-term monitoring of at-risk bumble bee species in Michigan in an effort to understand and describe range shifts, and aide in the conservation efforts for these species.
