Steps to make newly introduced beavers more at home in waterways have been reversed by environmental chiefs, after they were identified as a threat to protected salmon.
The Scottish Environmental Protection Agency (SEPA) inspected a section of the Aber Burn in Gartocharn earlier this month, ordering the RSPB to remove brash from the water which was preventing protected Atlantic Salmon from migrating to spawn.
Last month RSPB Scotland moved a family group of seven beavers to the Loch Lomond Nature Reserve, with two young kits killed last week.
