A short trekking on a trail through the swamp introduces us to the life of the beavers of the natural reserve and landscape of Tierra del Fuego.
The non-native species was introduced in 1946 as a potential source of commercial fur trading. When the fur trade industry was unsuccessful, the beavers were released.
But the North American beavers have no natural predators in the area. In their native habitats such as Canada, bears and wolves prey on the beavers and keep the population under control.
Tierra del Fuego National Park in Argentina is especially threatened, as the beavers are destroying long-protected trees.
As well as felling trees, beavers create dams that flood certain areas and thus drown other trees and vegetation.
Our guide explained there was not only a negative side to the beaver presence. The construction of dams creates a whole new ecosystem. The fish and bird population has increased considerably because of it. Of course, our guide making his living of it could have been just a little biased ;)
