Provide artificial nest sites for bumblebees
A trial of 172 nest boxes of six types (unequally replicated), carried out on farms in Wisconsin, USA in 1953, showed that bumblebees will nest in wooden nest boxes or half-buried flower pots at the surface, wooden boxes attached to buildings 1 m above ground, or in metal cans or roof tile enclosures buried underground (Fye & Medler 1954). Flax straw, old mouse nests or felt were added as bedding. Overall, 34% of the nest boxes were occupied, by five species of bumblebee, including three now thought to be declining in some parts of North America (Xerces Society 2008): the red-belted bumblebee Bombus rufocinctus, the yellow bumblebee B. fervidus and the half-black bumblebee B. vagans.
