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. [80]
The beavers are then put into a bunker where they wait until they're released into drought- and fire-prone areas with the hopes that they'll create their own colonies.
According to the state's Department of Fish and Wildlife, the beaver population in North America used to range between 100 million and 200 million but now totals between 10 million and 15 million.
Environment, health and safety (EHS) (or health, safety and environment –HSE–, or safety, health and environment –SHE–) is an interdisciplinary field focused on the study and implementation of practical aspects environmental protection and safeguard of people's health and safety, especially in an occupational context.
Beaver damage to the environment of Tierra del Fuego has been extensive, including structural changes in habitat, including the destruction of riparian trees, hydrological changes to rivers via the creation of dams, sediment deposition and increasing retention and accumulation of nutrients and organic matter in rivers and streams.

It is hoped that Wilson and Willow will transform the ecosystem and their impact will be tracked.
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 ...
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 ...
