Hunted to extinction across the UK 400 years ago for their pelts and oil from their scent glands (known as castoreum), we have a vision for returning this charismatic animal back to London where it once thrived. In January 2021, working with the Beaver Trust, under the London Beaver Working Group, we brought together some of London’s key conservation organisations, community groups and environmental decision-makers in London to discuss the possibility of beavers in our Capital once again.
