Situation in Spain (geography and conservation)
This huge Argentinean rodent has been present in Europe since 1920, where it is considered a pest species because of the damage it does to wetlands. It spread into the Basque Country and Navarra from France where it escaped from fur farms, and is still restricted to small riverine enclaves in this area. Currently an adult coypu's only natural predator in Spain is the domestic dog, though with the recent spread of the wolf this may change.
