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

  journal={PLoS ONE},
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. Significant differences in abundancies of other litophilic fish species and evenness of representation by species in the community were detected upstream and downstream of the beaver dams. Sea trout parr marked with RFID tags passed through several successive beaver dams in upstream direction, but no tagged fish were detected…

The influence of Eurasian beaver Castor fiber activity on fish assemblages in small steppe rivers in Russia

In recent decades, the Eurasian beaver (Castor fiber) has once again become the keystone species in small river ecosystems in Russia. In many places, beaver activity has resulted in a significant

Ecosystem experiment reveals benefits of natural and simulated beaver dams to a threatened population of steelhead (Oncorhynchus mykiss)

Beaver mediated restoration may be a viable and efficient strategy to recover ecosystem function of previously incised streams and to increase the production of imperiled fish populations.

Meta-analysis of environmental effects of beaver in relation to artificial dams

Globally, artificial river impoundment, nutrient enrichment and biodiversity loss impair freshwater ecosystem integrity. Concurrently, beavers, ecosystem engineers recognized for their ability to

Fish assemblage changes over half a century in the Yellow River, China

It is suggested that river basins which experienced different types and levels of stressors by anthropogenic perturbations can produce varied effects on their temporal trends of species assemblages.

Dam busy: beavers and their influence on the structure and function of river corridor hydrology, geomorphology, biogeochemistry and ecosystems

Beavers (castor fiber, castor canadensis) are the most influential mammalian ecosystem engineer, heavily modifying river corridors and influencing hydrology, geomorphology, nutrient cycling, and

Wild Trout Trust View on Beaver – Trout Interactions

In June 2015, arguably the most comprehensive synthesis to date regarding a species reintroduction, Beavers in Scotland, was submitted to Scottish Ministers. The report draws on 20 years of work on

Beaver: Nature's ecosystem engineers

This article concludes by examining future considerations that may need to be resolved as beavers further expand in the northern hemisphere with an emphasis upon the ecosystem services that they can provide and the associated management that will be necessary to maximize the benefits and minimize conflicts.

Corrigendum: Ecosystem experiment reveals benefits of natural and simulated beaver dams to a threatened population of steelhead (Oncorhynchus mykiss)

This corrects the article DOI: 10.1038/srep28581 to indicate that the author of the paper is a doctor of medicine rather than a scientist, as previously reported.



Influence of rainfall and beaver dams on upstream movement of spawning Atlantic salmon in a restored brook in Nova scotia, Canada

In a restored, third‐order stream in northern Nova Scotia, Canada, we used redd counts over 12 years to examine the influence of beaver dams and the timing and intensity of autumn rains on spawning

Stream flow, salmon and beaver dams: roles in the structuring of stream fish communities within an anadromous salmon dominated stream.

This model suggests that community distribution may be a function of semipermeable obstructions, streamflow and the distribution of the anadromous species affecting resident stream fish species richness, evenness, biomass and production.

Effects of beaver dams on the fish fauna of forest streams

Low potential for restraint of anadromous salmonid reproduction by beaver Castor fiber in the Numedalslågen River catchment, Norway

It is concluded that the presence of beaver on similar catchments will likely have only an insignificant negative impact on the reproduction of sea trout and salmon.

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

In a small stream in eastern Canada, the effects of an ephemeral beaver pond on the growth and maturity of age-2 Atlantic salmon Salmo salar parr tagged with passive integrated transponder tags are studied.


Beaver ponds act as reproductive "sources" for fish on the landscape, while adjacent stream environments act as potential reproductive "Sinks," and large-scale spatial relationships between beaver ponds and streams, along with the influence of discharge on the permeability of the boundaries between these habitats, are critical in controlling fish dispersal.

Qualitative and quantitative effects of reintroduced beavers on stream fish

Reintroduction of beaver (Castor spp) may facilitate rehabilitation of freshwater habitats providing a cost-effective sustainable means of improving ecological conditions. Despite extensive research,

Seasonal Changes in Habitat Use by Juvenile Coho Salmon (Oncorhynchus kisutch) in Oregon Coastal Streams

It is concluded that if spawning escapement is adequate, the production of wild coho salmon smolts in most coho Salmon spawning streams on the Oregon Coast is probably limited by the availability of adequate winter habitat.


We used a spatial survey of fish assemblage structure in streams and beaver ponds to: (1) determine the effects of beavers on fish assemblage structure at the reach and drainage basin scales, and (2)
