A family of wild beavers has been spotted in England for the first time in nearly 500 years.
"Beavers are a "keystone species", meaning they provide more important ecosystem services than their numbers alone would suggest. Known as "ecological engineers", their dams, burrows and ditches and the branches they drag into the water create habitats for a host of other species. Their dams slow rivers down, reducing scouring and erosion, and improving water quality by holding back silt."
Provided the government doesn't get involved.... this could be an exciting new beginning for the beaver population in the UK.
