Bumblebees make bee line for gardens, National Bumblebee Nest Survey finds
...blebees are important pollinators of our crops and wild
plants, but their populations have declined dramatically over the past 50 years. The decline is thought to be linked to the impact of modern farming methods on bumblebees' food plants. But as well as food, bumblebees need nesting sites for queens to ...
