Human-animal conflict caused by wild boar (Sus scrofa) is one of the urgent problems in wildlife management in China at present, but usually the cost is high and the effect is little. Understanding the habitat selection pattern of important behavior states such as foraging, resting, and moving of wild boars is extremely important for the development of scientific management strategies and avoidance of human-animal conflicts. In this study, wild boars (5 females, 8 males) in the mixed agroforestry area on the southern slope of the Lesser Khingan Mountains were studied. Based on their satellite location tracking movement data from 2019 to 2022, the Hidden Markov Model (HMM) was applied to identify three behavioral states of foraging, resting and moving of wild boars. Then the step selection function (SSF) was used to study the habitat selection of the three behavioral states. The results showed that the wild boars had different habitat requirements for foraging, resting, and moving, but they all avoided deciduous needle-leaved forests, and there were obviously sex-based differences, with females avoiding agricultural fields. Topography is the main factor affecting habitat selection for three behavioral states of female wild boar in spring and male and female wild boars in winter, while topography and vegetation type are the main factors affecting habitat selection for three behavioral states of male wild boars in spring. Female wild boars, in spring, chose habitats with high elevation and small slope to rest, forage and move, and preferred shady slopes for resting and foraging, while in winter they chose sunny slopes with high elevation and large slope to rest and forage, and preferred to move in mixed forests and sunny slopes. Male wild boars in spring chose to rest in mixed forests and shady slopes with high slope, forage in mixed forests, deciduous broad-leaved forests and areas with low elevation, and move in deciduous broad-leaved forests, within evergreen broad-leaved forests, areas with low elevation, low slope and close to rivers. In winter, male wild boars chose the sunny slopes with high slope, high elevation and close to rivers, to rest and forage in areas close to rivers with small slope, and move in evergreen broad-leaved forests, sunny slopes with small slope and close to rivers. The results can provide a basis and new ideas for the prediction and early warning of wild boar destruction in the region, the selection of capture sites and the development of control measures.
