Current distribution, status and patterns of spread of the Eurasian beaver Castor fiber, and the implications for management
Reduced to 1200 animals in 8 small refugia by the end of the 19th century, natural spread and reintroductions have led to a powerful recovery in Eurasian beaver range and populations.
Population and Distribution of Beavers Castor Fiber and Castor Canadensis in Eurasia
A review of the beaver’s history, population change, distribution, and population estimates in Europe.
Do introduced North American beavers Castor canadensis engineer differently in southern South America? An overview with implications for restoration.
This article looked at castor canadensis in Chile and Argentina in the 1990s. Data found that beaver eradication strategies and ecosystem restoration efforts should focus on the ecology of native ecosystems rather than the biology of beaver.
Beaver Made: The Botany of a Keystone Species
Beaver’s close co-evolution with plants.
The History of Beaver and the Ecosystem Services They Provide
This first webinar in the Association of State Wetland Managers (ASWM) and Bureau of Land Management (BLM) co-hosted six-part webinar series on beaver restoration details how beaver affect the land and the hydrologic impacts from loss of beaver through various hunting, trapping and removal activities. The webinar shared the role that beavers and beaver dam analogs (BDAs) can play in stream restoration.
Euro-American Beaver Trapping and Its Long Term Impact on Drainage Network Form and Function, Water Abundance, Delivery, and System Stability
Examines the long-term impact of historic beaver trapping in the United States on stream systems, the role of beaver trapping in arroyo formation in the American Southwest, why the significance of beavers was missed by the U.S. General Land Office surveys in the late 1700s to mid 1800s, and how that oversight impacted later researchers in the 1950s and 1960s as the study of fluvial geomorphology and hydraulic geometry emerged.
