Avanke, Bever, Castor: the story of beavers in Wales

Published by: Wetland Archaeology Research Project

4th February 2019

This book explores the history of Eurasian beavers in Wales. It combines archaeological and historical evidence to trace their presence and impact from the Ice Age to the 18th century. It looks at beavers' biology, as well as how they were and are intertwined with local culture: from place names to their place on high-status dining tables. The book also made the case for beavers' reintroduction in Wales. Please note, this resource is not open-access.

A geochemical perspective on the natural abundance of trace elements in beaver (Castor canadensis) from a rural region of southern Ontario, Canada

Published by: Science of the Total Environment

1st February 2019

In Canada, researchers studied how concentrated different chemical elements were in beaver tissue in comparison to the river water they were living in. It found that beaver tissues had particularly high concentrations of certain elements like Cadmium, but the paper goes into a lot more detail for each chemical and each tissue type. The authors suggest that this data can help monitor environmental quality in riverscapes. Please note, this resource is not open-access.

Solutions for protection of hydrotechnical dikes in the areas populated with beavers

Published by: Revista de Silvicultură și Cinegetică

1st January 2019

After being reintroduced to Romania, beaver populations have grown steadily, leading to conflicts with humans and human infrastructure. Here, underground metal nets were installed to protect drainage dikes whilst allowing beavers to live naturally. This text reports on this process and concludes that, although costly, this solution ensures long-term protection of the drainage dikes and mitigates the conflict.

The role of Eurasian beaver (Castor fiber) in the storage, emission and deposition of carbon in lakes and rivers of the River Ob flood plain, western Siberia

Published by: Science of the Total Environment

10th December 2018

Studies estimating greenhouse gas emissions from beaver dams had mainly focussed on North America. This study examined the impact of Eurasian beavers in Russia's Ob River watershed. The results showed significant methane emissions as well as enhanced carbon sequestration, aiding in short-term carbon removal. Please note, this resource is not open-access.

Environmental Factors Influencing Beaver Dam Locations

Published by: Journal of Wildlife Management

4th December 2018

Beavers are famous for building dams, but often they live in a river without building a dam! This study looked at what factors influence where they build dams and how those dams affect water levels. They found river depth - particularly its lowest point during summer - was a strong influence on whether dams were built. Dams raised water levels upstream, often upwards of 40 cm. This information can be helpful for landscape planning in areas where flooding could cause conflict with, for example, agriculture.
