Eradicate existing populations of invasive non-native species
Nagamitsu et al. (2010) removed foraging non-native buff-tailed bumblebees B. terrestris from six wooded sites (0.1-1.0 ha in size) in agricultural and urban landscapes in the Chitose River basin, Ishikari, Hokkaido, Japan, from 2005 to 2006, and monitored bumblebees at these and seven control sites from 2004 to 2006. The removal treatment increased numbers of the native bumblebee B. ardens in both years, and increased numbers of B. hypocrita in one year, but did not consistently lead to a drop in the numbers of B. terrestris trapped at the sites.
