The Himalayan forests are rich in biodiversity and distributed over a large extent from lower to higher elevations. The dependence of the locals for their daily requirements of fuel, fodder and medicinal plants is high on these forests. The study was conducted at altitude varied between 1725 and 3250 masl (above sea level) in Kumaun region. The study deals with the comparison of tree layer vegetation in higher elevation sites (HES) and mid elevation sites (MES) with reference to Diversity, Richness, Basal area (BA), Dominance and Important Value Index. The MES were dominated by mixed Quercus leucotrichophora and Pinus roxburghii forests where as HES sites were dominated by Quercus semecarpifolia and Aesculus indica forests and Rhododendron campanulatum in the understory. Across all the sites the tree species richness ranged between 9 and 15. Tree density was maximum (1400 trees/ha) at MES. Tree diversity and total basal area were maximum at HES. The study will be useful in developing baseline data for carrying out future studies. The data generated will be helpful for the conservation of biodiversity of the region.

Abstract A description is provided for Lophodermium balaramii found on dead fallen leaves and petioles of Rhododendron campanulatum. Some information on its dispersal and transmission and conservation status is given, along with details of its geographical distribution (India (Himachal Pradesh)) and host (R. campanulatum).

Climate change is affecting the forest ecosystems worldwide. Impacts of climate change are more perceptible at higher altitudes and can be easily detected along the elevational gradient. The main aim is to study the impact of elevation on the population structure of Rhododendron campanulatum D. Don and associated trees species at Manaslu Conservation Area, central Nepal. A total of 30 quadrats were sampled from 3600-4100 meter above sea level (m asl.) at altitudinal difference of 100 m with 5 quadrates in each altitude. The present study showed that R. campanulatum, Betula utilis, Abies spectabilis and Sorbus microphylla are the treeline species. R. campanulatum was the most dominant species with highest importance value index (IVI) along the altitudinal gradient. At 4000 m asl. S. microphylla was the codominant species. B. utilis was the codominant species at 3600 -3900 m asl followed by S. microphylla and A. spectabilis. R. campanulatum and A. spectabilis showed a sustainable regeneration. No seedling of B. utilis was found along the altitudinal gradient indicating that the regeneration of this species might be affected by unfavourable micohabitat (eg. deep shade). R. campanulatum and S. microphylla were found above the treeline indicating that the climatic conditions were favourable for their growth. The height, diameter and density of the species differed along the elevational gradient and showed a species specific trend. Journal of Institute of Science and TechnologyVol. 21, No. 1, 2016, page:
