Everything about The European Beaver totally explained
The
European beaver (
Castor fiber) is an endangered large aquatic
rodent which was hunted almost to extinction in
Europe, both for
fur and for
castoreum, a secretion of its
scent gland believed to have
medicinal properties.
Biology
Beavers are vegetarian, felling waterside trees to eat their bark and leaves, and eating other wetland vegetation such as the
rhizomes of
water lilies.
On rivers, the European beaver constructs a
dam of mud and sticks to create a lake. It then builds a lodge surrounded by water, like its close relative the
American beaver. However, in some areas with natural waterways it doesn't build a dam or lodge, but instead digs tunnels in banks and uses these as underwater entrances to burrows.
The European beaver is usually heavier than its North American relative, weighing up to 35
kg (77
lbs). It is also said to have weaker teeth and lesser reproductive capacity.
Survival
The European beaver survived in the wild in some places in Europe, and several thousand still live on the
Elbe, the
Rhone, the
Danube and in parts of
Scandinavia.
In many other places the beaver was hunted to extinction, and it's thought to have been lost from
Britain in the
sixteenth century.
Reintroduction
European beaver is now being
reintroduced to many places throughout Europe.
Mainland Europe
Beavers have been reintroduced in
Serbia.
Beavers have been re-introduced in
Bavaria and
The Netherlands and are tending to spread to new locations.
In
Sweden the beaver had been hunted to extinction by the end of the
nineteenth century. Between 1922 and 1939 approximately eighty individuals were imported from
Norway and introduced to nineteen separate sites within the country.
Norwegian beavers also played an important role in reintroducing the then extinct animal to
Finland, but there the population also includes a substantial number of
C. canadensis of
Canadian origin.
Britain
No beavers have yet been officially released into the wild in Britain – legal release would require a licence under the
Wildlife and Countryside Act 1981, as for all other animals not normally resident in the wild. However, several projects have established beavers in large fenced enclosures, where they live in a near-natural state.
In 2001 the
Wildwood Trust with
Kent Wildlife Trust imported two families of European beaver from Norway to manage a wetland nature reserve. The beavers were gifts from the Norwegian Government which would otherwise have formed part of the annual cull. The beavers are living in a 130-acre fenced enclosure at the wetland of Ham Fen. This five-year habitat management trial is being monitored by Oxford University. The monitoring ceased after two months following a delay with the release of the beaver and the drying up of funds.
Six European Beavers were released in 2005 into a fenced lakeside area
Gloucestershire.
In 2007 a specially-selected group of four Bavarian beavers were released into a fenced enclosure in the
Martin Mere nature reserve in
Lancashire. It is hoped that the beavers will form a permanent colony, and the younger pair will be transferred to another location when the adults begin breeding again. The progress of the group will be followed as part of the BBC's
Autumnwatch television series.
A colony of beavers is established in a large enclosure at
Banff,
Perthshire.
A beaver living wild was confirmed in
Scotland in early 2007 and was captured. It may have been released illegally.
In 2005 the
Scottish Government turned down a licence application for unfenced reintroduction. However, in late 2007 a further application was made for a release project in
Knapdale,
Argyle. This application was accepted, and the first beavers will be released in spring
2009
