How is the evidence assessed?
Supporting evidence from individual studies
Selective tree felling and removal of humus and nutrient-rich soil by scraping in a 1 ha area at Norton Heath Common, southeast England increased the range of common bumblebee species recorded within the scraped area from one in the first year to four in the second year (Gardiner & Vaughan 2008).Study and other actions tested
Forup et al. (2008) compared four ancient dry lowland heaths in Dorset with four paired heathland sites first restored from pine Pinus sp. plantation 11 to 14 years previously. There were no consistent differences between the communities of insect pollinators, including bees, at ancient and restored sites. There was no clear evidence that bees or other pollinators colonised restored heaths from the adjacent or nearby paired ancient heaths, implying that from a bee perspective, there is no need to site heathland restoration projects very close to ancient sites.Study and other actions tested
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.Study and other actions tested
