After near-extirpation in the early 20th century, beaver populations are increasing throughout many parts of North America. Simultaneously, there is an emerging interest in employing beaver activity for stream restoration in arid and semi-arid environments (collectively, ‘drylands’), where streams and adjacent riparian ecosystems are expected to face heightened challenges from climate change and human population growth. Despite growing interest in reintroduction programmes, surprisingly little…

Beavers Buffering Blazes: The Potential Role of Castor canadensis in Mitigating Wildfire Impacts on Stream Ecosystems
1. Beavers (Castor canadensis) are considered ecosystem engineers due to the influence of their dam-building activities on abiotic and biotic characteristics of stream ecosystems. After near…
Persistence at distributional edges: Columbia spotted frog habitat in the arid Great Basin, USA
TLDR
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, factors which threaten local or regional persistence.
Survey of Beaver-related Restoration Practices in Rangeland Streams of the Western USA
TLDR
It is concluded that the practice and implementation of beaver-related restoration has outpaced research on its efficacy and best practices and further scientific research is necessary, especially research that informs the establishment of clear guidelines for best practices.
Modeling intrinsic potential for beaver (Castor canadensis) habitat to inform restoration and climate change adaptation
TLDR
A generalized intrinsic potential model is developed that draws on remotely sensed measures of stream gradient, stream width, and valley width to identify where beaver could become established if suitable vegetation were to be present and serves as a preliminary screening tool that can be applied over relatively large extents.
Impacts of a Non-indigenous Ecosystem Engineer, the American Beaver (Castor canadensis), in a Biodiversity Hotspot
Non-native species having high per capita impacts in invaded communities are those that modulate resource availability and alter disturbance regimes in ways that are biologically incompatible with…
Livestock management, beaver, and climate influences on riparian vegetation in a semi-arid landscape
TLDR
It is shown that livestock management which emphasizes riparian recovery objectives can be an important precursor to beaver activity and it is described 11–39% increases in floodplain vegetation productivity where conservation-oriented grazing approaches or livestock exclosures and highBeaver activity occur together on low-gradient sites.
Beaver dams shift desert fish assemblages toward dominance by non-native species (Verde River, Arizona, USA)
TLDR
This study provides the first evidence that, relative to unimpounded lotic habitat, beaver ponds in arid and semi-arid rivers support abundant non- native fishes; these ponds could thus serve as important non-native source areas and negatively impact co-occurring native fish populations.
Using ecosystem engineers as tools in habitat restoration and rewilding: beaver and wetlands.
Habitat and forage selection by the American beaver (Castor canadensis) on a regulated river in the Chihuahuan Desert
TLDR
Examination of habitat and woody forage species during winter along the Rio Grande in southern New Mexico concluded that, while cottonwoods might require protection from beaver foraging, beavers were not having a negative impact on willows and did not promote saltcedars via ecological release.
Effects of changing climate on aquatic habitat and connectivity for remnant populations of a wide‐ranging frog species in an arid landscape
TLDR
The area of the Great Basin with suitable climate conditions for the Columbia spotted frog has declined by approximately 49% over the last century and will likely continue to decline under future climate scenarios, and connectivity among existing populations is quantified.

TLDR

TLDR
This article uses hierarchical patch dynamics to investigate beaver-mediated discontinuity across spatial and temporal scales and uses this conceptual model to generate testable hypotheses addressing channel geomorphology, natural flow regime, water quality, and biota, given the importance of these factors in river restoration.
