BeeWalk is a standardised bumblebee-monitoring scheme which involves volunteer ‘BeeWalkers’ walking the same fixed route (transect) once a month between March and October, counting the bumblebees seen and identifying them to species and caste (queen, worker, male) where possible.

Established in 2008, and opened to the public in 2010, the twin aims of the scheme are collecting abundance and distribution data on Britain’s bumblebees, and using this data as widely as possible to analyse population trends and carry out other research as appropriate.

The information collected by BeeWalk volunteers is integral to monitoring how bumblebee populations change through time, and will allow us to detect early warning signs of population declines. All data collected will contribute to important long-term monitoring of bumblebee population changes in response to changes in land-use and climate change and, ultimately, to informing how we manage the countryside.

Results so far

After three scoping years and seven in operation as a public recording scheme, the BeeWalk dataset now stands at 91,117 validated records of 24 bumblebee species. That’s 291,321 individual bees!

For a full summary of progress to date, download the BeeWalk Annual Report 2018.

In collaboration with the Centre for Ecology & Hydrology (CEH) and the University of Kent, we have published a paper extending the information that we can extract from BeeWalk data, making it even more useful! Read it here.

Current and planned work

The central goal of the BeeWalk programme is to be able to reliably evaluate the trends in British bumblebee populations. By October 2019, our aim is to:

  • Recruit, train and retain existing highly-motivated volunteers, increasing volunteer recorder numbers from 350 to 500 individuals.
  • Increase the number of transects walked from 373 to 500.
  • Increase the number of records submitted from 65,000 to 120,000.
