Abstract:Food is one of the key factors affecting wildlife survival. Food habits study helps us understanding the important relationship between wildlife and their living environment, and it could also be used to evaluate the quality of the animals’ living conditions and their habitats. The seasonal diet variation of the Chinese goral, Naemorhedus griseus, was studied through microscopic analysis of the fecal contents in Saihanwula national nature reserve. The results found that 31 plant species belonging to 27 genus and 16 families were foraged by Chinese goral around the year. The diet composition of plant species was significant different from other three seasons, which was significantly lower during winter (2=28.865, <0.001). The proportion of arborous plants in goral’s diet were the lowest in all seasons, and the species of arborous plants in winter was the least with only 1 species. At the same time, the forbs were also had significant seasonal changes (2=17.213, <0.001), that was consumed less in winter than in other seasons. The Shannon-Wiener diversity index and food niche width from high to low were summer, autumn, winter and spring, while Pielon's evenness index in order (from high to low) were summer, autumn, winter and spring. The results showed that the feeding habits of the Chinese goral had a certain adaptability to the seasonal vegetation changes, which is affected by an integrative factor of plants richness, arable parts, seasonal activities and energy budget of the animal.
