The history of the Eurasian Beaver Castor fiber in Scotland

In 1995 Scottish Natural Heritage proposed a feasibility study to examine the case for reintroducing the Eurasian Beaver Castor fiber to Scotland. Following IUCN guidelines, an important first step is to demonstrate that the Beaver was once a native of Scotland and that the causes of its extinction no longer pose any threat to reintroduced animals. Therefore, palaeontological, archaeological and historical evidence for the former existence of the Beaver in Scotland and the causes of its extinction are reviewed.
Palaeontological and archaeological evidence suggest that the Eurasian Beaver was once widely distributed throughout mainland Scotland. Historical evidence suggests that although it was once probably fairly common, it became extinct between the twelfth and sixteenth centuries, most probably towards the latter. The main cause of its decline and extinction was probably hunting for its pelt, meat and castoreum, but habitat destruction may have been important in the loss of some small isolated populations.
Given that the causes of extinction of the Beaver in Scotland now no longer exist or can be effectively controlled, there is no reason why a feasibility study cannot proceed to assess the practicalities of a reintroduction.
