We studied the distribution of beaver-impacted mineral wetlands and peatlands in a 7,912 km2 area of the Canadian Rocky Mountains. Using aerial photography and an existing wetland database, we inventoried 529 wetlands at elevations of 1,215 to 2,194 m; peat soils were found at 69 % of the 81 field verified wetlands.

To determine whether reintroduced beavers, as an example of native herbivorous megafauna, can increase freshwater biodiversity at the landscape scale and to compare effects on two contrasting taxonomic groups.

The research gathered in this paper discusses the beaver’s effects on: wetland carbon cycling, riparian forest structure, and biodiversity. This thesis also covers the relationship between beaver populations and the existence of wetlands, particularly the way in which beavers are an essential part of wetland ecosystems.

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.

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.

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.

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.
