Resumo
The wild boar (Sus scrofa Linnaeus, 1758) is considered one of the 100 worst invasive species in the world and is present
in the high-elevation forests in Brazil. Our objective was to understand how landscape and atmospheric conditions affect space
use by wild boars. We hypothesized that wild boars would be more frequent at lower elevations, warmer and wetter forested
areas, and away from human disturbances. After three years of data collection (2013–2016) using 16 camera traps, 881 independent records were obtained with a mean of 4.44 ± 9.25 pigs per record. Wild boar frequency of occurrence was higher at lower
elevations, in more humid and warmer areas, and farther away human disturbance factors, corroborating our initial hypothesis.
Understanding space-use patterns of wild boars is necessary for the design of management strategies that target areas of more
intense usage, as well as for defining more effective population-control techniques.
