Beavers have occasionally wandered into Downtown Ottawa, including Parliament Hill, Major's Hill Park, and Sparks Street. [83] Beavers caught in the urban core of Ottawa by the National Capital Commission's conservation team are typically brought to a wildlife centre, and later released near the Ottawa River, close to the Greenbelt.

Beavers hold a very specific biological niche in the ecosystem: constructing dams across river systems. Niche construction is the ecological process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism’s environment, or it can encompass the active movement of ...
Allogenic engineers modify the biophysical environment by mechanically changing living or nonliving materials from one form to another. Beavers are the original model for ecosystem engineers; in the process of clearcutting and damming, beavers alter their ecosystem extensively.
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
A family of beavers has been released in the Paradise Fields wetlands area, in Ealing, west London.
The state’s beaver program is now soliciting proposals from other landowners who want beavers on their properties for restoration purposes, and staffers plan to select at least one additional ...
Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as ...
In an extreme example, beavers require certain resources in order to survive and reproduce, but also construct dams that alter water flow in the river where the beaver lives. Thus, the beaver affects the biotic and abiotic conditions of other species that live in and near the watershed. [ 17 ]
