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.
Study on how beavers alter freshwater ecosystems and increase aquatic production to determine how these changes influence the magnitude and lateral dispersal of aquatic nutrients into terrestrial ecosystems
Beaver activity (i.e., damming of streamflow) holds significant potential to impact water quality, specifically in-stream nutrient processing.
A 44 minute Baltimore Sun podcast by Dan Rodricks on beavers and their impact. He interviews beaver experts Frances Backhouse, Mike Callahan, and Scott McGill on the history, present management and future of beavers in North America. Recorded in Feb. 2, 2018
Review of research about the positive and negative effects of beaver towards fish
In-depth report on how beaver could provide benefits to local residents and visitors well into the millions of dollars per year in Utah.
Study on how beaver dams affect coastal marshes and their Phosphorus and pH levels
This study quantifies the impacts of beaver on stream hydrologic and temperature regimes, and highlights the importance of understanding the spatial and temporal scales of those impacts. We explored the impacts of beaver dams on hydrologic and temperature regimes at different spatial and temporal scales within a mountain stream in northern Utah over a 3-year period spanning pre- and post-beaver colonization.
A review by the University of Southampton of how the reintroduction of beaver will affect fish in Scotalnd
The Effect of Beaver (Castor canadensis) Dam Removal on Total phosphorus Concentration in Taylor Creek and Wetland, South Lake Tahoe, California
The presence of beaver ponds in Taylor Creek could improve water quality by reducing the phosphorus load entering Lake Tahoe.
Beavers Buffering Blazes: The Potential Role of Castor canadensis in Mitigating Wildfire Impacts on Stream Ecosystems
The potential role of beavers in mitigating wildfire impacts on stream ecosystems
This review summarizes how beaver impact ecosystem structure and geomorphology, hydrology and water resources, water quality, freshwater ecology, and humans and society.
Summary of the benefits of beavers, their conflicts with humans, and the policies and conditions that affect their survival
Effects of Beaver Impoundments on Dissolved Organic Matter Quality and Biodegradability in Boreal Riverine Systems
Assessment of the changes in dissolved organic matter quality and the biodegradation patterns in beaver systems across Sweden
In rural watersheds of southern New England with high Nitrogen loading, denitrification from beaver ponds may remove 5 to 45% of watershed nitrate Nitrogen loading. Beaver ponds represent a relatively new and substantial sink for watershed Nitrogen.
