4. Discussion<br />

Lama guanicoe is a generalist species, which can adapt to a wide spectrum of environments<br />

(Raedeke 1980; Puig et al. 1997), from closed forests where mainly consumed leaves <strong>and</strong><br />

sprouts of Nothofagus saplings (Martínez Pastur et al. 1999; Pulido et al. 2000) to sub-alpine<br />

grassl<strong>and</strong>s (Rebertus et al. 1997), where grasses <strong>and</strong> sedges are the main food. Domestic<br />

herbivorous mostly include grasses in their diet, but also can consumed saplings in adverse<br />

conditions, mainly in winter when forest are preferred among other site types because provides<br />

them with protection. Lama guanicoe avoid presence of domestic herbivorous, using<br />

environments free of them, independently of the season. This native species is a natural<br />

component of these native forests, but the impact in the unmanaged <strong>and</strong> harvested st<strong>and</strong>s can<br />

increase according to the livestock density in the area. The knowledge of diet <strong>and</strong> plant<br />

distribution at l<strong>and</strong>scape level allows us to propose management strategies for native <strong>and</strong><br />

domestic herbivorous, minimizing the impact to the forestry activities.<br />
