Provide artificial nest sites for bumblebees
Sladen (1912) placed 112 underground nest boxes for bumblebees in his garden near Dover, in Kent, England in 1910 and 1911. Boxes were buried cylinders of tin or terracotta, or holes in the ground with a wooden cover, and a 38-75 cm tunnel leading to them. They were occupied by six species of bumblebee, including the short-haired bumblebee Bombus subterraneus now extinct from Britain. Thriving colonies developed in 13-19% of nest sites provided.
