Shrill Carder Bee Project

The Shrill carder bee is one of the rarest bumblebees in the UK. In the last 50 years, it has declined dramatically and is threatened with extinction in the UK.

In light of this, an exciting new project has been launched to conserve this charismatic bee in England. Buglife are working in partnership with the  Bumblebee Conservation Trust  as part of the ground breaking ‘Back from the Brink’ Programme.

We are working in the two areas of England where Shrill carder bee still occurs: Somerset & Wiltshire and the Thames Gateway. The main aims of the project are to:

  • Establish the current distribution of Shrill carder bee in England
  • Set up bumblebee monitoring at key Shrill carder bee sites through volunteer recruitment and training
  • Provide habitat management advice to land managers to improve habitat connectivity
  • Engage with local communities to raise the profile of the bee
  • Produce a species recovery plan for Shrill carder bee

How can you help?

We’re looking for volunteers in Essex and Kent to help with survey and monitoring work in areas where Shrill carder bee occurs. In 2018, we will be offering a number of free bumblebee identification workshops.

If you own or manage any land in the project area and want to help to make a difference to the conservation of Shrill carder bee and other pollinators then we would love to hear from you.

If you’re keen to get involved or would like to find out more about the project please get in touch with Rosie Earwaker - Shrill Carder Bee Project Officer (Thames Gateway):
