Diet of guanaco in sheep-free rangeland in Tierra del Fuego, Chile
Guanaco (Lamaguanicoe), the only native ungulate of Tierra del Fuego, uses the forests more extensively after the introduction of sheep. It is presumed that the regeneration of lenga (Nothofagus pumilio) is hampered by guanaco browsing. In this context, the diet of guanaco in Tierra del Fuego was ev...
