Beavers
- Dams built by beavers help in the growth of brown trout in Chile’s remote Tierra del Fuego, which is also the southern tip of South America, a study found.
- The beaver is a large, primarily nocturnal, semiaquatic rodent.
- They are the second-largest rodent in the world after the capybara.
- Beavers are known for building dams, canals, and lodges.
- Their colonies create one or more dams to provide still, deep water to protect against predators, and to float food and building material.
- When sites are available, beavers burrow in the banks of rivers and lakes. But they also transform less suitable habitats by building dams.
- IUCN status: Least Concern
