A trial to reintroduce beavers to Knapdale will end soon but has it been a success and do the public think it is a good idea?
A YouGov poll, commissioned for the Scottish Beaver Trial, found 60% of Scots support the reintroduction of beavers to the wild.
The species was hunted to extinction in Scotland in the 17th Century.
