Abstract

Quercus leucotrichophora forests are a repository for biological diversity, carbon, nutrient reserves, and multipurpose Himalayan tree species and crucial for sustaining rural livelihoods, controlling ecosystem services. As a result, their protection and sustainable usage in the future are essential to reduce the effects of climate change, as well as the biological and environmental stability of sensitive ecosystems in North-western Himalayan ecosystem. Hence the present investigation was carried out to document the natural regeneration status of Quercus leucotrichophora across different altitudinal gradients i.e., A1 (1200-1500 m), A2 (1500-1800 m) and A3 (1800-2100 m) above mean sea level (amsl) in Himachal Pradesh Forest ranges. Statistical procedures were used for collection of data, analyzation, and interpretation. The present study reveals that the decreasing trend of natural regeneration of Quercus leucotrichophora with altitude: A1 > A2 > A3 were recorded maximum at lower altitudinal gradient (1200-1500 m) (A1) and minimum at higher altitudinal gradient (1800-2100 m) (A3).
