Dibru-Saikhowa National Park (DSNP) comprises 340 km2 of core zone of Dibru-Saikhowa Biosphere Reserve in Assam, India. DSNP receives on average 3000-3500 tourists every year. Most of the visitors were on independent holidays often coming to the DSNP. Most of the visitors coming from outside the northeastern states are coming to DSNP as the second destination after the Kaziranga National Park, which is about 300 km from the DSNP. Recreational value of DSNP was estimated by using Travel Cost Method. Results show that the average consumer surplus per tourist per visit accruing to domestic tourists was Rs. 2892.50 and total annual recreational value of the DSNP was Rs. 10.11 million which is almost 40 times the total revenue (Rs. 2.50 lakh) earned by the DSNP in a year. This clearly shows that revenue collected through entry fee is not reflecting the true economic value of recreational services of the DSNP. The results of the study provide enough justification for enhanced investment from government in the DSNP to ensure continued flow of essential ecosystem services.

We studied temporal changes in biomass and net primary productivity of alpine grasslands at Tungnath in Garhwal Himalaya. Five different communities with similar elevations were taken for investigation. The above-ground biomass samples were harvested as close to the ground as possible. Similarly, below-ground biomass samples were collected from harvesting monoliths (25 x 25 x 30 cm). Aboveground net primary production was determined as the sum of positive changes in biomass and belowground net primary production was calculated as the difference between peak belowground biomass and preceding minimum biomass. The live shoot biomass increased from May till September in all communities except Trachydium roylei and Polygonum, which peaked in August. The dead shoot and litter biomass first decreased and peaked in all communities in October. Belowground biomass first decreased and then increased towards the end of the growing season. The belowground to aboveground biomass ratio ranged between 0.61-3.08. The aboveground net productivity ranged between 454.8-294.3 g m-2, and the belowground net productivity ranged between 346.3-102.4 g m-2.
研究了青藏高原通纳特高寒草地生物量和净初级生产力的时空变化。选取5个海拔高度相近的不同社区进行调查。地上生物量样本尽可能靠近地面采集。同样，从收获的巨石(25 x 25 x 30 cm)中收集地下生物量样本。地上净初级生产量为生物量正变化量之和，地下净初级生产量为地下峰值生物量与之前最小生物量之差。5 ~ 9月，除羊草和蓼外，其余各群落的活枝生物量均呈上升趋势，8月达到高峰。各群落枯枝和凋落物生物量在10月先下降并达到峰值。地下生物量在生长季结束时先减少后增加。地上生物量比在0.61 ~ 3.08之间。地上净生产力在454.8 ~ 294.3 g m-2之间，地下净生产力在346.3 ~ 102.4 g m-2之间。

We assessed the areas under suitable habitats and population of ten high value medicinal herbs in alpine region of Uttarakhand, Western Himalaya. Topographic, landcover, physiographic, edaphic and bioclimatic variables were used to predict the potential distribution of these plants in the alpine vegetation zone. Field surveys were conducted to collect occurrence data, and the abundance of species was assessed through rapid mapping exercises. The study found that certain habitat types, particularly Danthonia-dominated grassy slopes, herbaceous meadows, and shrubberies between 3000-4100 m elevations on specific slopes, were preferred by the MAPs. Among the threatened MAPs, Allium stracheyi had the largest potential distribution area (588 km2) with a moderate abundance of 1.7 individuals/m2, while Aconitum balfourii had the smallest potential distribution area (100 km2) with low abundance (0.2 individuals/m2). The results of the MaxEnt analysis identified several significant contributing factors for the potential distribution of threatened species, including aspect, slope, vegetation type, mean diurnal temperature, and precipitation during the wettest months. Based on the potential distribution and abundance data, specific meadows such as Valley of Flowers, Kandara, Ralam, Milam, Tungnath, Panchachuli, and Pindari were identified as priorities for in-situ conservation and management efforts.

We made an inventory of vascular plants of Bankapura Peacock Conservation Reserve, located in the Haveri district of Karnataka. The study area covers ca 140 acres of land known for the high density of Indian Peafowl. Altogether we recorded 141 plant species belonging to 118 genera and 43 families. These include 116 dicotyledons and 23 monocotyledons, 1 pteridophyte and 1 gymnosperm. Fabaceae is the most dominant family as it contributes about 17% of the total flora.

Effects of seed orientation and depth at the time of sowing on germination and seedling vigour of Madhuca longifolia (J.Konig.) J.F.Macbr. were investigated. Seeds with uniform size were sown in sand filled earthen pots at 1.5, 3.0 and 5.0 cm depths, adopting three orientations of the embryo, viz., upright (embryo facing up), horizontal and inverted positions. The experiment was laid out in a completely randomized block design. Percentage germination, days taken for initial emergence, speed of germination, germination index, root and shoot length and dry matter production, vigour index I and vigour index II were calculated. Placing the seeds with the embryo in upright position at a depth of 1.5 cm and 3.0 cm resulted in early and higher germination, higher seedling growth, greater dry matter production and vigour index I and vigour index II.

We assessed the growth performance of Eucalyptus clones on salt affected areas of eastern Gangetic Plains for identification of suitable planting material. An experimental trial was established under statistical design of randomized complete blocks with three replicates and 3 x 2 m spacing for 13 clones IFGTB 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, FRI 100, 104, 124 of 02 Eucalyptus species (Eucalyptus tereticornis and E. camaldulensis) along with control for 14 treatments in Kamasin village of Pratapgarh district of Eastern Uttar Pradesh in year 2017. The clones of species E. camaldulensis in IFGTB series performed superior over FRI clones/species of E. tereticornis. The results of the analysis of variance (ANOVA) for mean height and girth increments showed high levels of significance. The results of growth performance indicated that all clones gave superior results for growth indicators as compared to control. On the basis of growth parameters, viz., height, girth at breast height, basal area and tree volume, in IFGTB series, the clones IFGTB 4, 8, 6, 10 and 1 performed superior over other clones, whereas in FRI series, the clones FRI 100 and FRI 124 performed superior over others.

This paper deals with the wood microstructure of twenty-nine samples of the ten important species of genus Salix L., viz., Salix acmophylla Boiss., S. babylonica L., S. daphnoides Vill., S. denticulata Andersson., S. x fragilis L., S. oxycarpa Andersson., S. tetrasperma Roxb., S. viminalis L., S. disperma Roxb. ex D.Don, and S. sikkimensis Andersson from India and adjacent regions (i.e., Myanmar and Tibet). Internationally acclaimed standard laboratory procedure was followed in the preparation of permanent slides. The qualitative and quantitative wood anatomical characters were studied as per the International Association of Wood Anatomists (IAWA) terminology for hardwoods. Photomicrographs were taken for showing the diagnostic features of each taxon. The selected Salix species had some similar qualitative wood anatomical features along with differentiating characters based on which species can be distinguished from each other. In addition to qualitative anatomical features, quantitative anatomical features also showed significant differences among species. The main differentiating anatomical characters were druses, vessel-ray pits, ray seriation, shape/outline of solitary vessels and vessel frequency based on which identification key was prepared.
