Beavers make their way through the city by traversing the city's waterways. The city of Toronto government, and the Toronto and Region Conservation Authority (TRCA) do not keep track of the number of beavers residing in Toronto, [81] although an estimate from 2001 places the local beaver population at several hundred.

Beavers are perfectly adapted for life in water and even have webbed rear feet. They have two thick, oily coats of fur to keep them warm and dry and both their ears and nostrils are valvular.
"A lot of the water in California is not from snowmelt. It's from the groundwater and these beavers are recharging it for us," Fairfax said. "They are sort of depositing water into the bank that ...
Beaver activity can affect the temperature of the water; in northern latitudes, ice thaws earlier in the warmer beaver-dammed waters. [70] Beavers may contribute to climate change. In Arctic areas, the floods they create can cause permafrost to thaw, releasing methane into the atmosphere. [71] [72]
A beaver dam or beaver impoundment is a dam built by beavers; it creates a pond which protects against predators such as coyotes, wolves and bears, and holds their food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species and ecosystem ...
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.
Beaver “engineers” build dams and canals that create connectivity between land and water; these beaver wetlands function as vital biodiversity hubs for plant and animal species, including many ...
Beaver dam, an animal construction which has a transformative effect on the environment. The beaver is a well known ecosystem engineer and keystone species. It transforms its territory from a stream to a pond or swamp. Beavers affect the environment first altering the edges of riparian areas by cutting down older trees to use for their dams ...
