KNOWLEDGE BASE

As part of the 5-year Scottish Beaver Trial, interim monitoring was carried out to understand the welfare of the released beavers. This study describes how two families had successfully established territories in the first year of the trial. Radio-monitoring proved difficult because of the terrain and the vegetation, so the authors said there would be a greater focus on visual observations in future.

This book is an accessibly-written summary of the natural history of beavers. It looks at the organisms as individuals, their behaviour - including as family units, their ecology and population dynamics, and a history of beavers' interactions with humans.

As part of the 5-year Scottish Beaver Trial, interim monitoring was carried out to understand the impacts of beavers on hydrology, biodiversity, and other factors. This study reported on field observations from 2010 and described beavers' impact on woodland ecosystems. Beavers cut down a lot of birch, willow, and rowan, avoiding hazel and alder. Many of these species were resprouting. Beavers tended to fell trees that were within 350 m of their lodge and 10 m of the water. The average diameter of felled trees was 5 cm.

As part of the 5-year Scottish Beaver Trial, interim monitoring was carried out to understand the impacts of beavers on hydrology, biodiversity, and other factors. This study reported on field observations from 2010 and showed that beavers had had minimal impact on the river habitat. Beavers were mainly active in the lochs and had few impacts on streams. The report notes that future surveys will thus focus on changes in standing water habitats.

This report was written as part of the Scottish Beaver Trial in Knapdale. It generated baseline data by surveying three ponds in which beavers had not yet settled, recording which species of aquatic plants were present. Elsewhere in the trial site, beaver dam construction had influenced on the types of plants growing by raising water levels.
