Beaver dam

Description:

A dam built by beavers at the end of the national park of Tierra de Fuego, Argentina.

Notes:

I heard a story from a guy from Ushuaïa. He told me that the beavers are not native from the reagion. Indeed the were brung in 1945 to breed them, for thier fur. Nowadays, the goverment is starting an eradication policy.... (in order to protect the Tierra de Fuego's biodiversity).
