Abstract:Summer caves of Masked palm civets (Paguma larvata) were surveyed on the north slope of Funiu Mountain in July and August, 2005. Twelve 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, average distance to trees, average distance to shrubs, shrub density. The results showed that summer caves of the Masked palm civet were located in broadleaf forests with high levels of canopy cover, shrub density and concealment, at an elevation of 900-1200 m on skew and steep, sunny and semi-sunny slopes. The caves were usually close to human residences and less than 100 m from a water source.
