Food habits of sika deer, Cervus nippon centralis temminck, in Mt. Ohdaigahara, central Japan, were investigated by the fecal analysis method from September, 1990, to June, 1991. The fecal analysis showed that the percentage of Sasa nipponica Makino et Shibata in the fecal composition was approximately 50% throughout the year, indicating that it was the main food plant. Bark and twigs were also found in the feces in all seasons, suggesting that the deer ate bark throughout the year. Even though the amount of the bark eaten per capita was small, the high density of deer may possibly cause serious bark damage. Barking can be one of the main causes of the mortality of Picea jezoensis Sieb. et Zucc. var. hondoensis (Mayr) Rehder and Abies homolepis Sieb. et Zucc. in Mt. Ohdaigahara.
