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