1. Habitat Loss
Many pollinators are in decline in the UK. In the last 30 years, two bumblebee species have become extinct and over the last century, four species of butterfly and more than 60 moth species have become extinct. It is thought that three-quarters of British butterflies are now in decline. Loss of flowers and habitat loss has been a leading contributor to this. Habitat loss as a result of increasing intensification of land use for agriculture, forestry and development has been widespread. Over 97% of all flower-rich grasslands have been lost since the 1930s, reducing pollen and nectar sources and leading to a serious decline in the wildlife depending on wildflower-rich habitat.
