Survey of distribution of beavers in Tayside in 2012

In response to evidence of increasing beaver (Castor fiber) activity in the Tay catchment, Scottish Natural Heritage (SNH) commissioned a survey to examine the status of beaver populations in the River Tay system. During the rapid survey, a total of 1,522 field signs and six beaver sightings were recorded. The survey results were combined with long-term observations of beaver activity recorded over several years to establish the population size, distribution and impacts of the beavers.
