Together, this sheds light on bumble bee populations, where they are thriving, and on which plants they are foraging -- and informs conservation and protection efforts.
U.S. Fish & Wildlife Service Fails to Designate Critical Habitat for the Rusty Patched Bumble Bee
The U.S. Fish & Wildlife Service decided to not designate critical habitat for the rusty patched bumble bee, despite its previous finding that habitat loss threatens the bee. Failing to designate critical habitat may hinder recovery of the rusty patched bumble bee, which has already been lost from more than three quarters of its historic range.
