Bark stripped from tree trunks and butts by Sika deer, Cervus nippon TEMMINCK, was surveyed in twelve 20×20m^2 plots within 3 forest types on Mt. Odaigahara, Nara Prefecture, Japan. About 90% of Picea jezoensis (SIEB. et ZUCC.) CARRIERE var. hondoensis (MAYR) REHDER and 57% of Abies homolepis SIEB. et ZUCC. trees were barked while deciduous broad-leaved trees such as Fagus crenata BLUME and Quercus mongolica FISCHER ex TURCZ. var. grosseserrata (Bl.) REHDER et WILSON were not barked. The percentages of barked trees in 5 Picea jezoensis var. hondoensis-Sasa nipponica MAKINO et SHIBATA plots on the eastern part of the mountain (1550-1600 m in alt.) were 57% whereas they were 49% in 3 Fagus crenata-Sasa nipponica plots (1450-1550 m) and 17% in 4 Fagus crenata-Sasamorpha borealis (HACK.) NAKAI plots (1300-1450 m) on the western part of the mountain. These percentages appeard to be closely correlated with the intensity of the habitat utilization by Sika deer, assessed by the grazing intensity on Sasa and Sasamorpha leaves and fecal pellet density.
