Guanaco Distribution in Northwest Patagonia

Abstract

Here are guanaco occurrences that we collected from archaeological, ethnohistorical and current sighting data from Northwest Patagonia (Argentina), separated in periods (Lata Holocene, Historic and Current). Likewise, we also provide different bioclimatic and anthropic variables that could contribute to explain guanaco distribution in Northwest Patagonia, as well as the R script to model guanaco distribution in each period and estimate the explicatory power of each variable. We found significant changes in guanaco distribution throughout time. Specifically, in the Current period (last 30 years of sightings) guanaco distribution shifted to the East, and the main explanatory variables are Human footprint and herders summer camps.
