The community structure and growing stock variations were studied in moist temperate Quercus floribunda forest on four different aspects and altitudesin Garhwal Himalaya during the year 1996. The total density and basal cover values in the tree layer varied from 250 to 340 trees/ha and 18.44 to 38.24 m2/ha respectively. The maximum number ofsaplings (400 saps/ha) of Quercus floribunda were observed on the hill base of SE aspect, whereas, the lowest number ofsaplings (80 saps,/ha) on the hill top of NW aspect. The maximum (1.8131) and minimum (1.4717) diversity values were reported for NE and SE aspects respectively. The highest total growing stock (349.0m3/ha) was observed on SW aspect. On NE aspect a strong positive correlation (r=+0.88) was observed between the growing stock values and diameter classes. Physicochemical properties of soils were found to be promising for the growth of Quercus floribunda forest on northern aspects as compared to southern aspects.
