Abstract

Quercus leucotrichophora and Q. floribunda were two important tree species of the montane zone of Garhwal Himalaya. Total litter production of Quercus leucotrichophora (site I) forest was estimated as 663.9±56.8 gm^-2 yr^-1 and Q. floribunda (site II) forest as 564.1 ± 27.74 gm^-2 yr^-1. Leaf fall contribution to the total litter fall was 530.0 ± 50.1 on site I and 446.0 ± 25.7 gm^-2 yr^-1 on site II. The litter decomposition rate on both the sites was maximum in August. Total litter decomposition after a period of 13 months on site I was 75.1 and on site II 66.6 %. Decomposition constant (K') values for these species were 0.75 and 0.67 respectively.

Abstract

Two study sites selected on the basis of the disturbance gradient at the elevation from 900 to 1,300 m asl in the sub-tropical zone of District Pauri of the Garhwal Himalayas were studied for the structure and diversity of the forest. Density, total basal cover, importance value index, similarity index, concentration of dominance, diversity index, beta diversity and equitability index were analysed for tree, shrub, sapling and seedling layers of the forests and compared for the both the sites. The forest sites showed differences in analytic characters. The concentration of dominance and the index of diversity were higher for the mildly disturbed forest site.
