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.

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 ...
"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 ...
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.
Kate Lundquist, director of the WATER Institute at the Occidental Arts & Ecology Center, said she expects California's changes will lead to fewer beavers killed in the state and a growth in ...
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 ...
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 ...
