As of 2020 the current population in Britain is estimated to be at 550 individuals.
450 individuals are thought to reside in the Tay catchment on the East coast of Scotland with 30 at the site of the official Scottish Beaver Trial on the West coast. A further 20 are thought to be wild on the River Otter in Devon with the remaining individuals found in fenced trials across England, Wales and Scotland.
While 550 may sound like a lot in comparison to countries across Europe Britain’s beaver population is very small. France has an estimated population of 16,000 beavers, Germany 35,000 and Poland 125,000!
