Idaho Beaver Restoration Assessment Tool Building Realistic Expectations for Partnering with Beaver in Conservation and Restoration

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.

Emulating Riverine Landscape Controls of Beaver in Stream Restoration

We have developed and implemented a simple approach that emulates the ecosystem engineering effects of beaver. This approach is less expensive and disruptive than typical large-scale engineering efforts and has the potential to restore both fish habitat and floodplain vegetation more rapidly than simply revegetating and waiting for the riparian zone to mature.  (Pg 246 – 255)

Beavers, Rebooted

Artificial beaver dams are a hot restoration strategy, but the projects aren’t always welcome.

Beaver (Castor Canadensis) of the Salinas River: A Human Dimensions-Inclusive Overview for Assessing Landscape-Scale Beaver-Assisted Restoration Opportunities

Study to gather and produce human dimensions-inclusive, basin-centralized beaver knowledge through an explorative, benefits-maximizing approach to landscape-scale BAR opportunities assessment in the Salinas River.

Alteration of Stream Temperature by Natural and Artificial Beaver Dams

In this study, we tracked beaver dam distributions and monitored water temperature throughout 34 km of stream for an eight-year period between 2007 and 2014. Our results suggest that creation of natural and/or artificial beaver dams could be used to mitigate the impact of human induced thermal degradation that may threaten sensitive species.

Mimicking & Promoting Wood Accumulation & Beaver Dam Activity with Post-Assisted Log Structures & Beaver Dam Analogues

Description of the design process for two types of low-tech structures, post-assisted log structures (PALS) and beaver dam analogues (BDAs).

Simple hand-built structures can help streams survive wildfires and drought

Low-tech stream restoration gains using beaver dam mimicry gains popularity as an effective fix for ailing waterways in the American West.

Low-Tech Process Based Restoration of Riverscapes Design Manual

The purpose of this design manual is to provide restoration practitioners with guidelines for implementing a subset of low-tech tools—namely beaver dam analogues (BDAs) and post-assisted log structures (PALS)—for initiating process-based restoration in structurally-starved riverscapes. ‘Low-tech process-based restoration’ is a practice of using simple, low unit-cost, structural additions (e.g. wood and beaver dams) to riverscapes to mimic functions and initiate specific processes. Utah State Univ., 2019.

BDA Pocket Guide – Utah Sate University

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.

Climate Change Adaptation Through Beaver Mimicry

Jeff Burrell with the Wildlife Conservation Society with demonstrates how installing inexpensive woody debris in streams to mimic beaver dams can encourage beaver damming to mitigate the negative effects of  less snow melt summer runoff due to climate change in Montana streams.

Working with Beaver in Pataha Creek to Restore Salmon and Steelhead Habitat: Assessment, Design, and Construction Report

The goal of this project is to test whether a restoration method developed and tested in Bridge Creek, Oregon will be suitable for restoring streams like Pataha Creek in southeast Washington.

Preston rancher restoring beaver to creek

Idaho rancher, Jay Wilde, and Joe Wheaton from Utah State University use BRAT, beaver restoration assessment tool, and identified good beaver habitat to help restore Birch Creek to year-round stream flow.

Beaver power provides year-long water to Idaho ranch

Idaho rancher, Jay Wilde, partnered with Anabranch Solutions to build BDAs, and the USFS and Idaho Fish & Game to relocate beavers into Birch Creek to help restore year-round stream flow.

Survey of Beaver-Related Restoration Practices in Rangeland Streams of the Western USA

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.

The Beaver Restoration Guidebook, Version 2.01, 2018

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.

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.

Identifying Where to Place Beavers and When to Use Beaver Mimicry for Low Tech Restoration in the Arid West

This second webinar in the ASWM-BLM Beaver Restoration Webinar Series focuses on making decisions about where beaver restoration and/or the use of beaver dam analogs (BDA) can have the greatest positive and least negative impacts. It includes a demonstration of Utah State University’s Beaver Restoration Assessment Tool (BRAT), a model that helps planners assess key parameters essential to beaver work.

Case Studies of Long-term Changes from Beaver Restoration Activities

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.

Beaver Restoration for Climate Resiliency

The final webinar in the ASWM-BLM Beaver Restoration Webinar Series showcases research which indicates that beavers are able to create and maintain wetlands resistant to both seasonal and multiyear droughts and that this landscape wetting and drought buffering goes on to reduce or prevent burning in wildfire. Perhaps instead of relying solely on human engineering and management to create and maintain fire?resistant landscape patches, we could benefit from beaver’s ecosystem engineering to achieve the same goals at a lower cost.

Coalition Building for Beaver Based Stream and Wetland Restoration Success, ASWM Webinar 2021

This fifth webinar in the ASWM-BLM Beaver Restoration Webinar Series focused on how coalition building is essential to advancing the practice of process-based stream and floodplain restoration by helping the regulatory environment be responsive to the evolving understanding around functioning, intact riverscapes.
