Effect of Agriculture and Presence of American Beaver Castor canadensis on Winter Biodiversity of Mammals

This study compared various measures of biodiversity levels of mammals in the winter months between wetlands on agricultural land and wetlands, as well as wetlands with active and inactive beaver colonies.

The Beaver Manifesto

Dr. Glynnis Hood has spent many years scientifically studying beavers and their ability to protect the landscape from climate change and drought. A very interesting and educational read. 2011

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.

Fire and beaver in the boreal forest-grassland transition of western Canada – A case study from Elk Island National Park, Canada

This study found that prescribed fires negatively affected beaver lodge occupancy, an effect compounded with frequent burns. Though prescribed fire is considered an important landscape restoration process, the frequency of prescribed burning should be mitigated to ensure that flooding by beavers can continue as a key process that maintains wetlands on the landscape.

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

Mitigating Human-Beaver Conflicts through Adaptive Management

This research project assessed the efficacy of pond levelling devices to mitigate flooding by beavers in Beaver County, Alberta.
