[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.

The beavers already threaten around sixteen million hectares of indigenous forest. [7] Unlike many trees in North America, trees in South America often do not regenerate when coppiced, destroying the forest. [9] As well as felling trees, the animals create dams that drown trees and other vegetation while creating freshwater ponds and lakes. [10]
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 shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ecosystem, beavers are considered a keystone ...
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 ...
Beavers create unburned islands where plants and animals can shelter from megafires, research has confirmed. A movement is afoot to reintroduce the rodents to the state's waterways.
The presence of the dam-making animals were confirmed after a recently planted tree was felled.
Despite being widespread in some beaver-inhabited areas, beaver canals and their environmental effects are much less studied than beaver dams. Beaver primarily develop canals to increase accessibility of river resources, facilitate transport of acquired resources, and to decrease the risk of predation. Beaver canals can be over 0.5 km in length ...
For years, beavers have been treated as an annoyance for chewing down trees and shrubs and blocking up streams, leading to flooding in neighborhoods and farms. California recently changed its tune ...
