The European Beaver (Castor fiber) is an endangered aquatic mammal that was hunted almost to extinction in Europe. This beaver is now being re-introduced throughout Europe. Several thousand live on the Elbe, Rhone, and Danube. It also lives in parts of Scandinavia. They have been reintroduced in Bavaria and The Netherlands. They are tending to spread to new locations. The beaver became extinct in Britain in the sixteenth century. There is now a project that is reintroducing the species to the country. Six European Beavers will be released into a lakeside area in Gloucestershire and allowed to roam wild. There are also plans to bring the beaver to Scotland.
