Reintroduce laboratory-reared bumblebee colonies to the wild
A replicated trial using 19 captive-reared colonies of the long-tongued bumblebee species B. appositus in subalpine meadows in Colorado, USA, found that four colonies regularly fed with sugar solution did not produce significantly more workers, males or queens than 15 colonies that were not fed (Elliott 2009).

Provide artificial nest sites for bumblebees
Elliott (2009) reports putting out 100 wooden nest boxes in subalpine meadows in Gunnison National Forest, Colorado, USA, of which approximately 10% were occupied by the Bombus appositus, a long tongued bumblebee and one of the three most abundant bumblebee species in the study area. These nest boxes were lined with cotton for insulation, but no further detail of their design is given.
