Impact of Beaver Dams on Abundance and Distribution of Anadromous Salmonids in Two Lowland Streams in Lithuania

European beaver dams impeded movements of anadromous salmonids as it was established by fishing survey, fish tagging and redd counts in two lowland streams in Lithuania.

Fish-Habitat Relationships and the Effectiveness of Habitat 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.

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)

The general ecology of beavers (Castor spp.) as related to their influence on stream ecosystems and riparian habitats, and the subsequent effects on fish – a review

Whether beaver-induced changes of fish populations are beneficial or harmful will depend on the prevailing constraints on local fish species composition and abundance.

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.

Evaluating landowner-based beaver relocation as a tool to restore salmon habitat

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.

Ecology and Movement of Juvenile Salmonids in Beaver Influenced and Beaver-Free Tributaries in the Trøndelag province of Norway

Study of salmon and trout movement upstream and downstream of beaver dams, and how the dams effect them

A Critical Review of the Effects of Beavers Upon Fish and Fish Stocks

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

Qualitative and Quantitative Effects of Reintroduced Beavers on Stream Fish

Review of research about the positive and negative effects of beaver towards fish

Dredge Creek Coho & The Impact of Beavers 2014

Article that investigates the relationship between beavers and coho salmon in the Mendenhall Recreational Area, Alaska

Final ESA Recovery Plan for Oregon Coast Coho Salmon (Oncorhynchus kisutch) 2016

This recovery plan provides guidance to improve the viability of coho salmon to the point that it meets the delisting criteria and no longer requires ESA protection. It includes strong recommendations to increase the number of beaver and recommends the use of BDAs to restore rearing habitat for salmon.

Guidelines for Salmonid Passage at Stream Crossings

This document provides guidelines for design of stream crossings to aid upstream and downstream passage of migrating salmonids, and is intended to facilitate the design of a new
generation of stream crossings.

Hydrologic and Geomorphic Effects of Beaver Dams and Their Influence on Fishes

This assesses how beaver dams effect fish habitat and how the removal of them may affect the fish

Influence of Beaver Activity on Summer Growth and Condition of Age-2 Atlantic Salmon Parr 2006

Study of the effects of an ephemeral beaver pond on the growth and maturity of age-2 Atlantic salmon in Eastern Canada
