Project summary:
This is a three-year, statewide environmental impact study into the effect of Bombus terrestris on Tasmanian ecosystems. The research program is intended to assess the current population and impact. Feral B. terrestris queens sometimes establish colonies in man-made domiciles, although they normally prefer underground, disused rodent nests. Locating, exposing and monitoring underground sites used naturally is almost impossible and so artificial nest boxes were used.
Treated-wood nesting boxes have proved to be very suitable for this purpose, as they are easily transported, weatherproof and cleanable. Bumblebee colonies are annual, not perennial, so it is possible for a new queen to be trap nested every year in the same box.
Methodology: Several dozen of the nesting boxes (hives) were set out in each location, some at Warra, in order to establish at least a low settlement rate (1-25%). Surveys were carried out to assess the current population.
Datasets: None available.
