The present study deals with 40 medicinal plant species used to cure a variety of ailments through traditional health care system by the local healers (Vaidyas). These plants were checked and verified from the available literature which revealed that the uses of these plants were newly recorded. Depth studies of 40 new recorded medicinal plants were documented with their different parts being used in herbal medicines. It was also found that one species or some times more species were used for curing one or many diseases together. The nature and type of symptoms of diseases reported of human beings were found varying across the region. All these different kinds of diseases were grouped in to three categories i.e. serious, moderate and common based on the risk factor and seriousness of disease in consultation with doctors practicing different streams of treatment i.e. Vaidyas, Ayurvedic and Allopathic. About more than 40% of local inhabitants were consulted, so as to reveals their perceptions on ranking of 10 common ailments prioritized by the local people based on their preference for opting herbal system of treatments. The traditional herbal system of medicine is one of the most important prevailing systems in the area where modern health care centre are rare or in very poor conditions.

The Khokhan Wildlife Sanctuary (KhWLS) located in the Kullu district of northwestern Himalaya and covering an area of 14 km 2 has not been explored for documenting the structure and composition of vegetation. In this study we examine the site/habitat characteristics, assess the diversity of tree species, delineate forest tree communities, assess the regeneration pattern of tree species, and suggest conservation measures. Sixty-five sites were sampled between 1640 - 2400 m asl and for each site, habitat characteristics, altitude and dominant species were noted. Seventeen forest tree communities were recorded. Cedrus deodara community was the most widely distributed followed by Quercus leucotrichophora, Abies pindrow and Quercus semecarpifolia communities. Cedrus deodara community had maximum density of trees (1468 Ind ha -1), seedlings (1290 Ind ha -1) and saplings (1172 Ind ha -1), while Picea smithiana community recorded the maximum total basal area (186.2 m 2 ha -1). Of the 17 forest tree communities identified, eight showed maximum regeneration of the dominant species, six showed maximum regeneration of the co-dominant species indicating the possibility of at least partial replacement of the dominant species by the co-dominant species in the future; and three communities showed poor or no regeneration of the dominant species indicating a total replacement of the dominants in the coming years. Long term monitoring of these tree communities for their conservation management is suggested. © International Society for Tropical Ecology.

Water scarcity is becoming a major problem in High Mountain Basins of Indian Himalaya. Access to fresh water becomes a core concern for every dweller in the summer season all across the Indian Himalayan Region. This paper presents an assessment of two low yielding perennial springs in one of the urban center located in the very steep mountain slopes of Lesser Himalaya. Spring hydrographs were analyzed to investigate the variability and availability of spring flow in three seasons. Dynamic spring flow volume in storage and time at which the flow may cease were also assessed, as they play a crucial role for planning short-term measures. The linear model using the exponential decay equation is found to be sufficiently accurate to model the recession characteristics of spring outflow from the hardrock aquifers for winter season, as the main contribution comes from baseflow with delayed interflow, which is slow diffuse flow in nature. The present study examines the findings from 1 year of spring outflow and rainfall when deficient monsoonal rainfall (moderate drought) is recorded in major parts of the country. The data can play a significant role in estimating dependable minimum water availability from the spring outflow and planning for appropriate capacity of low to medium storage structure for conserving the excess water which goes unutilized even during the high scarcity period. The analysis of duration curve suggests, more focus should be given for conserving the surplus water available during the monsoon through appropriate storage structures, which can be used during the leanest month. © 2011 Springer-Verlag.

Community dependence on forest resources for diverse needs has high implications for long term management of forests. Sustainable extraction of non-timber forest products (NTFPs) is considered best feasible strategy for forest conservation in biodiversity rich areas. This paper examines the heterogeneity of NTFPs use by tribal communities in northeast India, a global hot spot by examining diversity of NTFPs at-large, its consumption pattern, and contribution to rural income and forest revenue. A total of 343 NTFPs recorded used for diverse purposes by tribal communities. When species choice grouped as per use category, utilization for medicinal (163 species), edible fruits (75 species) and vegetables (65 species) purposes was reasonably high. Community dependence on forest resources was 100% for firewood and house construction material. 76 plant species were sold in three major local markets while an additional 22 species traded at commercial scale mainly outside the state. NTFPs contributed 19-32% of total household income for different tribal communities, which was significant. Illicium griffithii, Rubia cordifolia, Oroxylum indicum, Swertia chirayita, Litsea sebifera, Taxus wallichiana, Valeriana jatamansii, Thalictrum foliolosum, Picrorhiza kurrooa, Everniastrum cirrhatum, Cordyceps sinensis, Aconitum fletcherianum, Nardostachys jatamansi, Picrorhiza kurrooa, Gymnadenia orchidis, Calamus, Quercus and Pinus roxbughii were important commercial species. NTFPs also generated substantial revenue to the State government, though it is falling year after year, which is alarming. To meet community livelihoods, income and forest revenue from NTFPs, it desires a thorough management plan and policy guidelines for these resources from all line departments. The knowledge on diversity, its consumption pattern, and contribution to rural income and forest revenue may enable planners to accurately plan sustainable management of NTFP resources and community development in near future. © 2011 Elsevier B.V.

Swertia chirayita, a critically endangered medicinal herb, is being over-harvested in the wild. Understanding seed germination is a pre-requisite to ensure species conservation. The germination of seeds collected from six microhabitats was studied at 20°C, 25°C, and 30°C, both under a 14/10 h light/dark photoperiod and in continuous darkness. Two-way ANOVA indicated that microhabitat and temperature significantly affect seed germination, germination rate, germination recovery (GR), and GR rate. Overall, the seeds collected from under canopy showed a significantly (p < 0.05) higher germination than those from open habitats, at 20°C, 25°C, and 30°C (14/10 h light/dark photoperiod). Germination was negligible in continuous darkness but after transfer to a 14/10 h light/dark photoperiod, the seeds from under canopy significantly recovered at 20°C and at 25°C (p < 0.05), and showed the highest germination percentage compared to seeds collected from tree base, stump base, shrubberies, and grassy slope. Similarly, at 30°C, seeds from under canopy recorded the highest GR percentage. In general, seed germination, mean germination rate, seed GR, and GR rate were significantly greater (p < 0.05) at 25°C. Among the microhabitats tested, variation in GR rate was significant (p < 0.05). Seeds were confirmed to be positively photoblastic. © 2012 Copyright Taylor and Francis Group, LLC.
