Other affected species were the garden bumblebee, tree bumblebee, southern cuckoo bumblebee and buff-tailed bumblebee.
The bumblebee expert also shared how individuals can play their part in supporting the insects: “The key thing is having big populations because big populations are resilient populations.
Dr Richard Comont, science manager at the BCT, said: “The 2024 results from BeeWalk highlight just how vulnerable our bumblebee populations are to shifting climate and environmental conditions.
“All of the stuff you see about planting flowers in your garden, letting wildflowers grow, not using pesticides; all of that standard advice around increasing pollinator populations, not just bumblebees, that will allow us to have larger populations of pollinators.”.
Bumblebee numbers declined by nearly a quarter compared to the 2010-2023 average, figures from the Bumblebee Conservation Trust (BCT) show.
