Potential mitigation of and adaptation to climate-driven changes in California’s highlands through increased beaver populations
Evaluating the potential for beaver to adapt to and to mitigate anticipated changes in California’s higher elevation land- and waterscapes.
Wetlands are declining worldwide, and there is a great need for their restoration and creation. One natural agent of wetland engineering is beavers.
Habitat engineering by beaver benefits aquatic biodiversity and ecosystem processes in agricultural streams
Dam building by beaver in degraded environments can improve physical and biological diversity
when viewed at a scale encompassing both modified and unmodified habitats.
The goal of this study was to evaluate factors such as cattle grazing that may limit the occurrence of dam-building beavers in northern New Mexico.
Ecological engineering and aquatic connectivity: a new perspective from beaver-modified wetlands, 2014
This study demonstrated that beavers actively increase the volume-to-surface area ratio of wetlands by almost 50% and that their digging of foraging channels increases average wetland perimeters by over 575%. They concluded that exclusion or removal of beavers could limit ecosystem processes and resilience.
Beaver (Castor canadensis) mitigate the effects of climate on the area of open water in boreal wetlands in western Canada, 2008
This study examined how temperature, precipitation and beaver (Castor canadensis) activity influenced the area of open water in wetlands over a 54-year period in the mixed-wood boreal region of east-central Alberta, Canada.
The U.S. Dept. of the Interior, Bureau of Land Management blog reports that in arid, high country Oregon, a series of manmade beaver dams (Beaver Dam Analogs) have created a watery oasis.
Beavers Buffering Blazes: The Potential Role of Castor canadensis in Mitigating Wildfire Impacts on Stream Ecosystems
The potential role of beavers in mitigating wildfire impacts on stream ecosystems
Eurasian Beaver Activity Increases Water Storage, Attenuates Flow and mitigates diffuse pollution from intensely-managed grassland
A site is monitored to understand impacts upon water storage, flow regimes and water quality.
