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.
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.

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.
A study of beaver control measures to help land management agencies weigh against large-scale removal programs
Study that finds beaver-induced changes to habitat quality, stability, and connectivity may increase spotted frog population resistance and resilience to seasonal drought, grazing, non-native predators, and climate change.
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 review by the University of Southampton of how the reintroduction of beaver will affect fish in Scotalnd
Review of research about the positive and negative effects of beaver towards fish
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.
Trout and Salmon Movements in Two Idaho Streams as Related to Temperature, Food, Stream Flow, Cover, and Population Density
Comparison data on temperature, food abundance, stream flow, cover and population density with trout and salmon movements.
Tested how assisting beaver to create stable colonies and aggrade incised reaches of Bridge Creek could create measurable improvements in riparian and stream habitat conditions and abundance of native steelhead.
This review summarizes how beaver impact ecosystem structure and geomorphology, hydrology and water resources, water quality, freshwater ecology, and humans and society.
Educational article on the value of beavers by the Habitat Program supporting fish habitat conservation and restoration across Alaska, Washington, Oregon, California, and Idaho. Includes video and other helpful links.
