In 2003 Scottish Natural Heritage commissioned Forest Research to test methods of monitoring the impact of beavers on woodland vegetation in the re-introduction site in Knapdale, Scotland. The methods provide an assessment of damage by beavers as well as by deer that may browse the re-growth of trees that beavers have felled.
The report describes a field test of a method as well as suggesting improvements to the methods and approaches to undertaking full-scale monitoring.
