So excited to see this paper out — determining bumblebee nesting preferences using standardized surveys led by Sami Dolan. We found 25 nests over two years in MN and WI and found that bumblebees prefer to nest in prairie and edge habitat rather than forests.

Prairie and edge habitats provide valuable nesting resources for bumble bees (Bombus) in the midwestern U.S - Apidologie
Bumble bees use three main habitats to complete their life cycle: foraging habitat, overwintering habitat, and nesting habitat. Overall, the majority of bumble bee research has focused on the foraging...

Pollinators like bees, bumblebees & butterflies have too few habitats, often of insufficient quality. A new international study, including Lund University, shows these insects can benefit from a much larger habitat than prescribed in the EU:s biodiversity strategy.
