Beavers (Castor spp.) are ecosystem engineers that induce local disturbance and ecological succession, which turns terrestrial into aquatic ecosystems and creates habitat heterogeneity in a landscape. Beavers have been proposed as a tool for biodiversity conservation and ecosystem restoration. So far, most research has compared biodiversity in beaver wetlands and non-beaver wetlands, but few studies have explored how beaver-created succession affects specific taxa. In this study, we… 

How beavers affect riverine aquatic macroinvertebrates: a review

Background As ecosystem engineers, the construction of dams by beavers alters stream habitat physically and biologically, making them a species of interest for habitat restoration. Beaver-created

A Biodiversity Boost From the Eurasian Beaver (Castor fiber) in Germany’s Oldest National Park

Freshwater ecosystems are among the most threatened ecosystems on the planet. Beavers are important engineers in freshwater ecosystems and reintroduction programs have enabled the recovery of beaver

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

The effects of beaver impoundments on montane stream fish communities



Whole‐community facilitation by beaver: ecosystem engineer increases waterbird diversity

Wetlands are rich in biodiversity, but globally threatened. After a long period of regional extirpation, beavers have recently returned to many European areas and are now restoring wetlands. The

Rewilding wetlands: beaver as agents of within-habitat heterogeneity and the responses of contrasting biota

Independent of habitat creation beaver are significant agents of within-habitat heterogeneity that differentiates BP from other standing water habitat; as an integral component of the rewilding of wetlands re-establishing beaver should benefit aquatic biodiversity across multiple scales.

Invertebrates in Beaver-Created Wetlands and Ponds

Eurasian (Castor fiber) and North American (Castor canadensis) beavers are semiaquatic mammals that modify the hydrology of streams and other water bodies by constructing dams throughout the

Habitat dynamics of beaver Castor canadensis at two spatial scales

Abstract We studied habitat dynamics of the Canadian beaver Castor canadensis in a boreal forest landscape in southern Finland at two scales: the beaver pond level and the landscape level. To explore

The beaver as an ecosystem engineer facilitates teal breeding

In boreal areas beaver facilitate teal breeding by enhancing both resource abundance and habitat structure, and this study studied the effect of beaver flooding on breeding success of a dabbling duck, the teal.

An ecosystem engineer, the beaver, increases species richness at the landscape scale

It is suggested that ecosystem engineers will increase species richness at the landscape scale whenever there are species present in a landscape that are restricted to engineered habitats during at least some stages of their life cycle.


Beavers are increasingly viewed as "ecological engineers," having broad effects on physical, chemical, and biological attributes of north-temperate landscapes. We examine the influence of both local

Ecosystem Alteation of Boreal Forest Streams by Beaver (Castor Canadensis)

Beaver (Castor canadensis) alter the structure and dynamics of aquatic ecosystems with a minimum of direct energy or nutrient transfer. Through dam building and feeding activities, beaver act as a

Beavers alter stream macroinvertebrate communities in north‐eastern Utah

Understanding changes in macroinvertebrate communities is important because they play a large role in stream ecosystem functioning, and they are an important food resource for fish. Beaver‐induced
