Understanding the main factors in the extent and distribution of wild boar rooting on alpine grasslands

摘要: Wild boar Sus scrofa L. rooting is a large and frequent disturbance, very extended all over the world. However, its impact in some sensitive habitats, such as alpine subalpine grasslands remains unknown. These are considered important sites for biological conservation traditional grazing activities, frequently affected by wild rootings. In this study, we selected three study representing range of scenarios Pyrenean grasslands, with differing protection status management. We assessed extent rooting, determined main variables that influence their distribution, taking into account interactions among them. Our results showed significantly Pyrenees especially protected non-hunting areas (up to 12% surface). The distribution disturbed was influenced hierarchical suite variables, which vegetation, certain plant communities, most important. apparent preference dense might be associated soil depth, hardness diversity feeding resources. importance other topography, distance primary resources or management, site dependent. A broad understanding effects relationships provide insights actual factors affecting selection. hypothesize selection habitat, followed conditions uprooted human underlying shape grasslands.
