Restore heathlandAction Link
Henson et al. (2009) sampled bumblebees visiting flowers on six ancient and six restored patches of heathland on the Isle of Purbeck, Dorset, England. The restored sites had been restored from pine plantation around 10 years previously. The species richness and abundance of bumblebees were similar on ancient and restored sites, as were those of bumblebee protozoan parasites, external and tracheal mites. But conopid flies, a type of internal bumblebee parasitoid, were significantly less abundant on restored sites than ancient sites.
