英文摘要

In order to realize the significance of oak forests for ecology and economy of the Himalayan region, the present study attempts to objectively characterize disturbance intensities and their impacts on compositional features of identified Oak forests, i.e. Banj-oak (Quercus leucotrichophora A. Camus), Tilonj-oak (Q. floribunda Lindley) and Kharsu-oak (Q. semecarpifolia J. E. Smith) in west Himalaya. Amongst studied forests, Q. leucotrichophora and Q. semecarpifolia forests exhibited high sensitivity towards disturbance intensities. In both forests, increasing level of disturbance significantly lowered tree density, dominance and natural recruitment (seedling and sapling density). Q. floribunda forests, however, appeared relatively more resilient to anthropogenic disturbances. Amongst studied oak forests, Q. semecarpifolia forests with overall poor natural regeneration are in a most critically endangered demographic state. However, a slightly improved regeneration (i.e., seedling density) in moderately disturbed plots is indicative that such plots may be utilized most suitably for in situ revival of these forests. Effect of disturbance intensities on tree population is an important subject for forest ecology and management and the present study highlights a need for adopting different management strategies across disturbance intensities in diverse oak forests of west Himalaya.
