Beavers bring environmental benefits [View all]
Beavers are beneficial to the Scottish environment, say academics from The University of Stirling.
A study into the ecology and habitat engineering of beavers reintroduced to a site on Tayside in 2002 has found the creatures can improve biodiversity, minimise pollutants and reduce downstream flooding.
Examining head water streams which drain water from 13 hectares of Scottish countryside, scientists compared areas where beavers had been active with areas in which they were absent. The study formed part of a programme of research at this site by Stirling scientists that has been ongoing since 2003.
Leading the research Dr Nigel Willby of the School of Natural Sciences, said: "Our study found that beaver behaviours have several benefits for the environment. Their dam building skills help restore degraded streams and increase the complexity of the surrounding habitat, consequently increasing the number of species found by 28 per cent. The dams also help improve pollutant levels and store flood water."
