Bumble bees are among Northern Michigan's most important native pollinators, supporting the reproduction of wildflowers, native plants, and agricultural crops while helping sustain healthy and diverse ecosystems. Unlike managed honey bees, bumble bees are native wildlife, with different species adapted to the region's forests, meadows, wetlands, dunes, and other natural communities. However, several species have experienced significant declines, and some are now considered threatened or endangered. Habitat loss and fragmentation, declining native floral resources, pesticide exposure, disease and pathogens, invasive species, and a changing climate can all affect bumble bee populations and their ability to successfully nest and reproduce. Protecting diverse native plant communities, reducing pesticide use, preserving nesting and overwintering habitat, and monitoring populations are critical to their long-term conservation. By protecting bumble bees, we are also protecting the plants, wildlife, and ecosystems that depend on the pollination services these remarkable insects provide.
