Habitats throughout the UK should be protected with a purpose to save bumblebees, a decade-long examine has discovered.

Researchers used knowledge on bumblebee numbers, collected by the general public, to offer essentially the most detailed overview at the moment potential of what the bugs want from a habitat.

They discovered a variety of variations between bumblebee species within the forms of habitat they’re related to.


However the examine means that reversing the lack of semi-natural areas might be the only most typically efficient step in bumblebee conservation.

One third of the UK’s 24 species of bumblebee are listed as species of conservation concern as a result of they’re being present in fewer locations.

In line with researchers on the Bumblebee Conservation Belief, Karlsruhe Institute of Know-how and the College of Edinburgh, this advised a one-size-fits-all strategy to bumblebee conservation is not going to successfully defend all species.

Subsequently conservation efforts should be rigorously tailor-made to specific species, they are saying.

Dr Penelope Whitehorn, on the Karlsruhe Institute of Know-how, who led the examine, mentioned: “Our outcomes counsel that reversing the lack of semi-natural areas corresponding to wetlands would be the single most typically efficient motion for bumblebee conservation, whereas enhancing habitats in city and arable areas may benefit specific uncommon species.


“As one of the nature-depleted nations on the earth it’s actually vital that we higher defend our native species and habitats within the UK.”

The examine recognized the forms of habitat that might be focused for dialog.

It discovered that arable areas – appropriate for rising crops – have been vital for uncommon species like the big backyard bumblebee, the biggest species within the UK.

Massive areas of semi-natural land, like moorland, have been vital for numerous completely different species such because the moss and the brown-banded carder bees, and the bilberry bumblebee.

The information for the examine was offered by a long-running citizen science undertaking, which the researchers see as important for each gathering the info and fascinating the general public in conservation.


Dr Whitehorn mentioned: “Our examine highlights the worth of citizen science for understanding bumblebees and their habitats. Citizen science additionally provides everybody an opportunity to contribute to defending these species.”

The analysis additionally discovered that queens and males of a number of species have been significantly related to areas of scrub, bracken and herbs, suggesting that these habitats are good for nesting.

Employee bees have been extra generally related to hedges and lanes, suggesting these are good for offering meals.

Richard Comont, science supervisor on the Bumblebee Conservation Belief, mentioned: “Bumblebees want areas with plenty of flowers accessible from March proper by means of to September/October.

“Bees lose this very important useful resource when habitats are misplaced fully as a result of they’re both constructed on or become different environments or degraded by means of issues like pesticide use.”


The examine was based mostly on knowledge from the Bumblebee Conservation Belief’s BeeWalk scheme, a citizen science undertaking involving greater than 500 volunteers throughout the UK who perform month-to-month monitoring walks, figuring out and counting bumblebees.

A mix of this data and land cowl knowledge, local weather knowledge and detailed observer-collected habitat knowledge was used to have a look at associations between 14 UK bumblebee species and forms of habitat.

Subsequent the researchers hope to search out out why completely different species are related to completely different habitats, so the precise circumstances will be created and preserved for them.

The findings are printed within the British Ecological Society’s Journal of Utilized Ecology.
