| Summary: | Worldwide vicugna numbers are slowly recovering after the implementation of conservation measures in several areas of the Andean Puna. Amongst some communities, vicugnas are sustainably managed through captures, shearing, and release schemes. In this study, we explored habitat use and interactions between vicugnas and domestic livestock in Jujuy, Northwest Argentina. We measured the habitat selectivity of vicugna by evaluating the relationship between the availability and its use of vegetation. We estimated the extent and overlap of habitat niche, as well as the foraging effort of vicugnas on the basis of their individual behaviour. Vicugnas and domestic livestock were highly selective in their use of land. They also had similar foraging preferences, grazing rather on the mixed steppe grasses and grasslands that offered greater grass cover. The distribution of vicugna in relation to domestic animals differed according to species and density. With mean density of llamas, vicugnas showed mixed herds but with any other livestock and greater densities, they were segregated. In mixed grazing, when vicugnas engaged with llamas, no behavioural interaction or competition was observed. The presence of herders with dogs was the main stress factor for vicugnas. Here we discuss the importance of a multi-specific management approach. |
