Moose (Alces alces cameloides) is typically representative of the fauna of the frigid temperate zone and has been put on the Chinese second priority list of protected animals. The moose of northeast China is on the southern most edge of its distribution in Asia. To study resource selection characteristics of moose and their response to human distur-bances and forest resource variables, the field work was conducted in Heilongjiang Provincial Shengshan Forestry Farm, which is located in the northwestern slope of Lesser Khingan Mountains, northeastern China, from January to March in both 2006 and 2007. A total of 428 plots were examined within the study area. Signs of moose use were found in 19 plots. Based on the analysis of resource selection function, we found that moose selected areas with higher densities of mixed deciduous broadleaf patch and mixed coniferous and broad leaf patch, and a higher NDVI value. Moose avoided settlement 6 km away and remained low probability of occurrence within 3 km from roads, whereas higher within 4 km from trails. Our results suggested that the behavior of avoidance for human disturbance (i.e. settlement and roads) may indirectly pose habitat loss. Therefore, resource selection function models and corresponding graphsof important habitat disturbances can be used to guide and evaluate future development plans.
