Reducing nutrient runoff in streams is an important task to reduce algae blooms and associated environmental damage in large waterbodies. Beaver Dam Analogs (WTBDA) are an means to address this problem. These Water Tight Beaver Dam Analogs (WTBDA) present a novel approach to this technique that also aim to restore eroded seasonal creeks to perennial wetlands.

A case study of the impacts of beaver dams on a low gradient, fine-grained alluvial channel on the Atlantic Coastal Plain, illustrating the role that exists for beavers in stream restoration.

A synthesis of scientific literature and our current level of: 1) understanding of the relationship between habitat quantity and quality and salmon production, 2) quantify the improvements in salmon production and survival that can be expected with different restoration actions, and 3) use models to help identify habitat factors limiting production and quantify population-level responses to restoration.

The Low-Tech Process Based Restoration of Riverscapes Pocket Guide is an illustrated and condensed version of the Design Manual. The pocket guide is designed to fit in your pocket (4 x 6”) to use as a reference in the field. 2019.

Study on how beavers alter freshwater ecosystems and increase aquatic production to determine how these changes influence the magnitude and lateral dispersal of aquatic nutrients into terrestrial ecosystems

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.

This third webinar in the ASWM-BLM Beaver Restoration Webinar Series focused on the long-term changes in riverscapes that result from beaver restoration.  Where intense stream restoration is needed, people are identifying low-tech process-based methods that combine the management of grazing, beaver and other approaches that engage processes to create self-sustaining solutions.

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 study proposes that live vegetation and beaver dams or beaver dam analogues can substantially accelerate the recovery of incised streams and can help create and maintain complex fluvial ecosystems.

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.

The influence of beavers bringing more wood into rivers and river corridors

The potential role of beavers in mitigating wildfire impacts on stream ecosystems

Impact of beavers regarding drought and wildfire in the Methow River Watershed

This review summarizes how beaver impact ecosystem structure and geomorphology, hydrology and water resources, water quality, freshwater ecology, and humans and society.

Beaver dams and manmade Beaver Dam Analogs (BDA’s) on the John Day River system in OR accelerated recovery of steelhead trout.

This study provides empirical evidence that beaver can influence hydrologic processes during the peak flow and low?flow periods on some streams, suggesting that beaver can create and maintain hydrologic regimes suitable for the formation and persistence of wetlands.
