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.
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.
Beaver Colony Density Trends on the Chequamegon-Nicolet National Forest, 1987 – 2013

Persistence at Distributional Edges: Columbia Spotted Frog Habitat in the Arid Great Basin, USA
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.

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.

Comparison data on temperature, food abundance, stream flow, cover and population density with trout and salmon movements.
Working with Beaver to Restore Salmon Habitat in the Bridge Creek Intensively Monitored Watershed
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.
