A decision support and planning tool for beaver management, to analyze all perennial rivers and streams in Utah. This model assess the upper limits of riverscapes to support beaver dam-building activities.

Late 1800s – 1900s beaver studies which cover a period of twenty-seven years through every State in the Union, Mexico, Canada, and Alaska.

Traditional restoration efforts are barely scratching the surface of what could be restored. Moreover, a disproportionate amount of funds are spent on too few miles of streams and rivers leaving millions of miles of degraded streams neglected. To fill this gap, restoration practitioners are increasingly trying restoration techniques that are more cost?effective, less intensive, and can more practically scale up to the enormous scope of degradation.

Report on capture success of beavers in box traps, box trap designs and modifications, field sets, and costs of purchasing and modifying traps.

Investigation into the social dimensions of wildlife reintroduction and an argument to emphasize the need to recognize societal perceptions in potential management solutions

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.

A study of beaver control measures to help land management agencies weigh against large-scale removal programs

Beaver relocation program by the Wyoming Game and Fish Department.

Relocating American beavers (Castor canadensis) from unwanted sites to desirable sites where damage exceeds stakeholder capacity) has been posited as a method to enhance in-stream habitat for salmonids in the Pacific Northwest.

Washington’s Cowlitz Indian Tribe’s ambitious project: to reintroduce beavers back into the Gifford Pinchot national forest, a wild region on the slopes of the Cascade mountains, as part of efforts to reclaim indigenous land management practices.

A review that investigates the mechanisms by which beavers act as ecosystem engineers, and then discusses the possible impacts of beavers on the biodiversity of Scotland.

Study that examines relationships between dam density, riparian area characteristics, and the riparian bird community in a semiarid landscape.

Survey that identifies a need to assess beaver-related restoration projects in western rangelands to increase
awareness, accountability, and to identify gaps in scientific knowledge.

Article that finds themes in responses to beaver reintroduction and offers observations that may positively influence future responses amongst affected individuals

This guidebook provides a practical synthesis of the best available science for using beaver to improve ecosystem functions. The overall goal is to provide an accessible, useful resource for those involved in using beaver to restore streams, floodplains, wetlands, and riparian ecosystems.

Research and monitoring activities over a 45-year period on the Quabbin Reservation in Massachusetts have provided an opportunity to follow changes in numbers and dynamics of an unexploited beaver population.

A review by the University of Southampton of how the reintroduction of beaver will affect fish in Scotalnd

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.

A comprehensive compilation of information related to beavers and their management with an emphasis on stream restoration.

This report shares the experiences and lessons learned regarding the use of beaver for restoration and climate change adaptation in a selection of American states: California, New Mexico, Oregon, Utah, Washington and Wyoming.
