Beaver: The North American freshwater climate action plan

Rivers and streams, when fully connected to their floodplains, are naturally resilient systems that are increasingly part of the conversation on nature-based climate solutions. Reconnecting waterways to their floodplains improves water quality and quantity, supports biodiversity and sensitive species conservation, increases flood, drought and fire resiliency, and bolsters carbon sequestration. But, while the importance of river restoration is clear, beaver-based restorationfor example, strategic coexistence, relocation, and mimicryremains an underutilized strategy despite ample data demonstrating its efficacy. Climate-driven disturbances are actively pushing streams into increasingly degraded states, and the window of opportunity for restoration will not stay open forever. Therefore, now is the perfect time to apply the science of beaver-based low-tech process-based stream restoration to support building climate resilience across the landscape. Not every stream will be a good candidate for beaver-based restoration, but we have the tools to know which ones are. Let us use them.

Restoring wetland biodiversity using research: Whole-community facilitation by beaver as framework

Wetlands are declining worldwide, and there is a great need for their restoration and creation. One natural agent of wetland engineering is beavers. The study was conducted in Finland to address facilitation of waterbird communities by between beaver activity. The article also evaluates how the results of the study have been used in management.

Beaver in the Drainage Basin: an Ecosystem Engineer Restores Wetlands in the Boreal Landscape

The research gathered in this paper discusses the beaver’s effects on: wetland carbon cycling, riparian forest structure, and biodiversity. This thesis also covers the relationship between beaver populations and the existence of wetlands, particularly the way in which beavers are an essential part of wetland ecosystems.

Seasonal Variation in the Home Range Size of the Eurasian Beaver: Do Patterns Vary Across Habitats?

The aim of this paper was to test whether the space use of Eurasian beavers seasonally varies and whether the pattern comprises diverse habitats.

Mobility of Settlements and Elements of the Biological Signaling Field of Beavers (Castor fiber) in the Basin of the Tadenka River (Prioksko-Terrasny Nature Reserve)

A study that suggests a high density of the biological signaling field is a sign of possible depletion of food resources, and can explain how beavers can have such a large range.

Ecosystem services provided by beavers Castor spp.

We aimed to recognise beaver-produced ecosystem services and quantify their theoretical value for the entire Northern Hemisphere.

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.

Livestock Grazing Limits Beaver Restoration in Northern New Mexico

The goal of this study was to evaluate factors such as cattle grazing that may limit the occurrence of dam-building beavers in northern New Mexico.

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

The Economic Value of Beaver Ecosystem Services Escalante River Basin, Utah 2001

In-depth report on how beaver could provide benefits to local residents and visitors well into the millions of dollars per year in Utah.

Beaver: Nature’s ecosystem engineers

This review summarizes how beaver impact ecosystem structure and geomorphology, hydrology and water resources, water quality, freshwater ecology, and humans and society.

Evaluation of the Ecological Impacts of Beaver Reintroduction on Aquatic Systems

Study on how beaver engineering and foraging has the potential to create unique and highly heterogeneous wetland and stream habitats

Beaver-Created Habitat Heterogeneity Influences Aquatic Invertebrate Assemblages in Boreal Canada

Demonstration on how beavers physically altered isolated shallow-water wetlands which then influenced aquatic invertebrates
