Summer caves of Hog badger (Arctonyx collaris) were surveyed on the north slope of Funiu Mountain in July and August, 2005. Sixteen environmental variables possibly pertaining to cave selection were measured, including altitude, vegetation type, slope, aspect, location, level of cave concealment, distance to water source, distance to disturbance, canopy cover, level of entrance concealment, number of entrances, cave type, average distance to trees, average distance to shrubs, shrub density, and tree falls. The results showed that summer caves of the Hog badger were located in broadleaf forests with high levels of canopy cover, shrub density and concealment, at an elevation of 900-1200 m on sunny and semi-sunny slopes, and on average 75-150 cm away from trees. Most caves were natural rock formations with only one entrance. The caves were usually close to human residences and less than 100 m from a water source. Tree falls were not favored by the Hog badger.
