Rapid industrialisation in Alberta, Canada, around the turn of the millenium has changed the types of habitat available, leading to an increase in deer populations and the wolf populations that prey on them. This has raised wolf encounters with caribou, which previously were able to stay away from wolves more effectively, contributing to declines in caribou. Beavers also became a more important food source for wolves during this time. This fascinating text describes in detail how industrialisation impacted predator-prey dynamics in this region and set out some implications for caribou conservation.

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.

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.

This report set out the reasons for, and feasibility of, reintroducing beavers to Wales. It describes beavers' ecology as well as its current legislative and reintroduction status across Europe. The authors also set out potential sources of conflict and mechanisms for managing those. A trial re-introduction is proposed, including ideas for funding and an exit strategy.
