Keywords: Jatropha curcas, Germination, Variation, Seed source, Heritability.
Abstract: Seed germination triats i.e. germination percent, germination value and germination energy in laboratory and nursery conditions were evaluated for 97 accessions of Jatropha curcas belonging to 10 stands in Uttarakhand. On the basis of all seed germination traits tree T1 of stand S8 were best. Stand S3, which was not the best stand of germination percentage on the basis of stand level analysis, had trees showing 86 percent laboratory germination on par with the trees having the highest germination percent (87.5%) in the study at tree level. High heritability (77%) and moderate genetic gain (21%) were recorded at stand level for germination percent at 5% selection intensity. The expression of germination traits was usually higher under laboratory than under nursery conditions. It was suggested that the collection of seeds for germination purpose should be done by taking individual tree as a unit rather than taking stand as unit of collection.

Abstract: Alpine timberline, considered to be important ecotone supports rich and highly vulnerable biodiversity and represent one of the most distinct boundaries between forest to tree less alpine areas. It has attracted geographers and ecologist to do research for a long time on th ohenomena it encompases. In recent time, alpine treeline ecotones across most of the world ' s mountains are being studied because of their potential for monitoring the effects of cimate warming on forest ecosystem. Besides, alpine pasture areas in and around timberline zone and commercially important medicinal plants along timberline have also been playing important role as a source of livelihood of mountain communities settled in nearby area. In recent time, with the change in socio-economic aspiration of local mountain communities there has been a rapid increase in pressure on natural resources in and around timberline area. However, compared to studies of timberline area of European Alps, Andes of South America and mountains of North America, which has reached a very advanced stage, very limited studies on timberline of Himalayan mountain range have been carried out. In the present paper, review of timberline research work carried out in the mountain ranges of Europe, North America and Himalaya have been carried out to highlight the gap in alpine timberline research work in Himalaya.

Abstract: Rheum australe Wall ex Meissn, a perennial herb, is distributed in the Himalayas from Kashmir to Sikkim at altitude of 2800-5200m. In Himachal Pradesh it is found growing in Chhota Bhangal and Bara Bhangal of Kangra; Pangi Bharmour of Chamba, Parvati Valley of Kullu, Dodra kwar, Khashadhar and Rohru ranges of Shimla district, Kinnaur and Lahaul Spiti districts. Population density is between 0.5 and 1.5 plant square meter in very restricted localities and is designated as endangered in status. The experiment on Rheum austrate was conducted to determine the effect of different organic manures, biofertilizers and NPK on growth and yield of Rheum austrate and also to work out its cost of cultivation to standardize the cultivation technology. The results showed that maximum plant height, above ground biomass, underground biomass and underground biomass yield was recorded maximum using NPK (120:60:30 kg/ha) and which was followed by Vermicompost + Azotobacter + PSB (10t : 5Kg: 5Kg) with a BCR of 8.09.

Keywords: Disturbance categories, Elevational range, Floristic analysis, Plant diversity, Population structure.
Abstract: The present study was carried out in broad leaved evergreen oak forests of Garhwal Himalaya, Uttarakhand, India (1500-2100 m amsl.) along disturbance gradient. In this study, some disturbance indicators i.e. canopy cover, stand density, grazing intensity, lopping intensity, number of cut stumps and climber invasion have been evaluated and with the help of these indicators the forest area has been categorized into three categories viz. undisturbed, moderately disturbed and highly disturbed. The study revealed that tree diversity decreased with increasing intensity of disturbance in case of tree and herb species but it was found maximum in moderately disturbed stands for both layers (tree, herb) whereas, in case of shrub species, Shannon diversity increased with increasing disturbance level. Simpson dominance index was found as reverse of the Shannon index in all three layers of vegetation for all disturbance categories. Almost same trend was found in species richness. It was found more vulnerable to disturbance in case of tree and herb layers as it decreased with increasing level of disturbance but its highest values were recorded in the moderately disturbed stands in both vegetation layers. On the other hand shrub species richness favored the disturbance has increased with increasing intensity of disturbance. As far as the regeneration is concerned, sapling and seedling density was decreased with increasing disturbance level but both the classes were found maximum in the intermediate level of disturbance. Diameter-density curves depicted a successive reduction in the number of trees from lower girth classes to upper. All the above variations in relation to species richness, distribution pattern and regeneration potential are related to anthropogenic interference.

Abstract: Present study concluded that the total plant species was greater in oak-deodar mixed forest in Central Himalayan region. This type of forest recorded more trees and shrubs whereas oak dominated forest constituted higher herbs. The tree and herb density was 1700 and 92000 respectively in oak dominated forest whereas shrub density was 2356 per ha. The A/F ratio of trees and shrubs was 0.363 and 1.39 in the mixed forest as compared to 0.023 and 0.89 in oak dominated forest. Further, A/F ratio of herbs was 1.45 in the latter to that of 0.6 in the former. The total cover (%) of shrubs was 5.23 and 6.18 whereas for herbs it was recorded as 13.46 and 10.29 in oak-deodar forest whereas for herbs it was higher in oak dominated forest. The assessment of the plant biodiversity in different forests revealed that various disturbances do not provide time for the ecosystem recovery and widen the forest gap and fragmentation of the land in the region.

Abstract: Herbaceous flora is the dynamic layer in a forest stratum that protects the soil and water regimes and improves productivity and soil fertility. Thus a study was conducted at Chilapatta Reserve Forest, West Bengal India to document the status of herb diversity, biomass and carbon accumulation. Stratified random nested quadrate sampling was adopted for analyzing the qualitative and quantitative characters. Forty nine herb species were recorded, of which seven are yet to be identified. Identified species were of 21 families and 36 genera. The herb diversity index, concentration of dominance, Shannon and Wiener index and evenness index was estimated as 0.62, 0.028, 4.46 and 2.27, respectively. Highest and lowest frequency was recorded 49.12 and 1.75 while relative frequency varied from 0.09 to 1.87. Herb density ranged from 2 to 11193 individuals ha-1 and relative density ranged from 0.05 to 1.76%. Most of the species were widely distributed and its abundance ranged from 0.80 to 12.76 while relative abundance ranged from 0.05 to 1.76%. Most of 0.16 to 1.73%. IVI values ranged from 0.47 to 5.27. The above ground portion of herbs accumulated the major portion of biomass and carbon.

Abstract: The present study deals with the phytosociological analysis, anthropogenic impacts and regeneration status of tree species in five dominant forest types along an altitudinal gradient in Paddar valley of Northwest Himalaya. The tree density varied between 179 to 245 trees/ha whereas the total basal area varied between 24.7 and 37.7 m2/ ha in five forest types. The value of Shannon-Weiner index (H1) was found maximum for western mixed coniferous forest (1.75) whereas Concentration of dominance (Cd) and Evenness (J1) were found maximum for dry temperate deciduous forest (0.41) and dry deodar forest (0.32) respectively. The maximum disturbance was found in the dry temperate deciduous forests due to heavy dependence of the locals on oak, Quercus baloot for fuelwood and fodder. The results pertaining to regeneration status of 18 tree species shows 4 species with good regeneration, 6 species with fair regeneration and 5 species with poor regeneration status of 18 tree species shows 4 species with good regeneration, 6 species with fair regeneration and 5 regeneration was good for mixed coniferous forest and birch fir forests, poor for broadleaved and coniferous forest and fair for dry temperate deciduous forest and dry deodar forests.
