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 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 ...
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 ...
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.
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.

The Eurasian beaver (Castor fiber) or European beaver is a species of beaver widespread across Eurasia, with a rapidly increasing population of at least 1.5 million in 2020. The Eurasian beaver was hunted to near-extinction for both its fur and castoreum , with only about 1,200 beavers in eight relict populations from France to Mongolia in the ...
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 ...
