The basic concept of phytosociology is crucial for the assessment of species composition and dynamic ecological succession of forests supporting ecological services,functions,disturbance,and resilience that lead to the development of integrated areas such as ecological niche modeling and contribute to identifying the valuable bio-indicators which can be used in framing conservation and management *** is one of the most dominant tree species of treeline ecotone in the Himalayan *** species is also considered as indicator species for monitoring the past and recent climate change *** current study was carried out in the natural populations of *** from the sub-alpine zone of North-western Indian *** birch dominated forest harbors a total of 305 plant species comprising Angiosperms(51 families,160 genera and 277 species),Gymnosperms(03 families,05 genera and 07 species)and Pteridophytes(07 families,11 genera and 21 species)with Asteraceae,Ranunculaceae and Rosaceae as dominant *** forests are found dominant in shady moist habitat and North West *** characteristics,anthropogenic and developmental activities affect the population structure of *** and associated ***,the species has fair regeneration status in the study *** acidic nature of soil pH and spatial variation in edaphic characteristics may be due to geographical differences,rooting patterns and litter accumulation of below and above-ground *** estimation of a representative population of *** from each site showed that TAGBD,TCD and TBD were found maximum in ST3(Hamta Pass II site).The CCA analysis determined that environmental variables such as altitude,organic matter,available phosphorous,organic carbon,available nitrogen,and electrical conductivity played a significant role in determining tree species composition and distribution in *** dominated forests.

Actinorhizal plants contain numerous antioxidants that may play a crucial role in preventing the formation of tumors.H-Ras p21,a member of the Ras-GTPase family,is a promising target to treat various kinds of *** in silico docking study was carried out to identify the inhibitory potential of compounds of these plants against H-Ras by using Discovery Studio 3.5 and by using Autodock *** studies revealed that four compounds,isorhamnetin-7-rhamnoside,quercetin-3-glucoside-7-rhamnoside（present in ***）,zeaxanthin,and translutein（present in ***） significantly bind with binding energies-17.1534,-14.7936,-10.2105 and-17.2217 Kcal/mol,respectively,even though they slightly deviate from Lipinski＇s ***,distribution,metabolism,excretion and toxicity（ADME/tox） analyses of these compounds and their stereoisomers showed that they were less toxic and *** them,isorhamntein-7-rhamnoside showed ***,these compounds can be further investigated in vivo to optimize their formulation and concentration and to develop potential chemical entities for the prevention and treatment of cancers.
