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.

Restoring wetland biodiversity using research: Whole-community facilitation by beaver as framework

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.

Livestock Grazing Limits Beaver Restoration in Northern New Mexico

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.

Human-made Beaver Dams Likely Save Natural Wetland from Extinction

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.

The Engineering in Beaver Dams

Review of beaver dam construction and how their technology may allow to create novel, nature based solutions for ecosystem redevelopment and river renaturalisation.

Evaluation of the Ecological Impacts of Beaver Reintroduction on Aquatic Systems

By

Study on how beaver engineering and foraging has the potential to create unique and highly heterogeneous wetland and stream habitats

Beaver-Created Habitat Heterogeneity Influences Aquatic Invertebrate Assemblages in Boreal Canada

Demonstration on how beavers physically altered isolated shallow-water wetlands which then influenced aquatic invertebrates
