Subject: Influence of seed sources and stratification on germination and growth of Betula utilis D.Don under Temperate conditions in Kashmir Himalaya
Keywords: Seed source, stratification, germination, seedling growth, conservation
Abstract: The present study reports the influence of two seed sources (Special forest division Tangmarg and Bandipora forest division) and effect of different stratification treatments on germination and seedling growth parameters of Betula utilis in temperate region of Kashmir Himalaya. The seeds were collected in the month of September-October and subjected to six stratification durations of fifteen days interval at 4˚C±1˚C using completely randomized design. The seeds from Bandipora forest division performed better in terms of germination and seedling growth parameters giving maximum germination of (73.19%, seedling height ( 33.97 cm) , collar diameter ( 5.42 mm) , leaf area ( 97.03 cm2/plant), number of leaves ( 11.67/seedling) , seedling vigor index ( 25.98).Among six stratification treatments of 75 days ( D6) registered significantly higher germination ( 83.25%) ,Plant height ( 43.08cm) collar diameter ( 6.04 mm) , seedling vigor index ( 36.05) , leaf area ( 129.91 cm2/plant) and number of leaves (15.83/seedling) .The study revealed that under nursery conditions, seeds from Bandipora forest division stratified for 75 days performed most promising treatment combination for obtaining better germination and seedling growth and hence recommended for mass multiplication of this species for conservation and management.

Subject: Biodiversity and Distribution of wild fleshy fungi in district Jammu, J&K, India
Keywords: Agaricaceae, Diversity, Distribution, Humicolous habitat, Rainy season
Abstract: Fungi, the most diverse group of organisms, are very important for the nutrient cycling of an ecosystem. Fleshy fungi are described as non-photosysnthetic hyphal eukaryotes which form macrosocopic fruiting bodies. They are mostly saprophytic, inhabiting different substratum and occurring in different seasons. The present study was conducted in five locations of district Jammu to study the diversity, distribution and seasonal availability of fleshy fungi. The results shows that a total of45 taxa belonging to 27 genera spread over 17 families and 7 orders were found in the study area. Agaricaceae was the most dominant family represented by 18 species .Bajalta had the maximum diversity with highest number of species ( 15) ,Menhinick’s richness ( 3.87) , Margalef’s richness (5.17) and Shannon’s diversity ( 2.71).Humicolous i.e., species preferences humic soil was the most common ( 55.6%) habitat for the macrofungus. The Principal Component Analysis also confirmed that humicoulous fleshy fungi are the driving habitat of the study area and the two agricultural sites Arnia and R.S. Pura are having close affinity. The availability of the fleshy fungi in the five sites varied significantly (ANOVA; F=13.31 and P<0.001) and rainy season (July to September months) was the most preferred season.

Abstract: Studies to assess carbon stocks and their potential for implementation of REED and REDD + projects and policies have been conducted by scientists, academicians and policy makers all over the world. The present study reports estimates of carbon pools and fluxes in forests of all Indian states and union Territories since 2003 to 2017.To estimate the carbon storage in state wise in forests growing stock data from 2003 to 2017 were used. Biomass data for the years 2003, 2009, 2011, 2013, 2015 and 2017 were used to calculate the net flux caused by deforestation and degradation, between five assessment periods i.e. Assessment Period fists (ASP 1; 2003-2009) ,(ASPII; 2009-2011) , ASPIII; 2011-2013), (ASPIV;2013-2015) and (ASP V; 2015-017).The estimated carbon stock (Mt) was 2912.14, 2768.87, 2745.69, 2569.01, 2618.84 and 2643.64 Mt respectively for the years 2003, 2009, 2011, 2013, 2015 and 2017.There was a net positive flux for first three assessment periods (698.04 Mt of CO2 in ASP I, 85.08 Mt of CO2 in ASPII, 648.4 Mt of CO2 in ASP III) and net negative flux ( -184.14 Mt of CO2 in ASP IV and -91.00 Mt of CO2 in ASP V) for last two assessment periods. The net flux also impacted annual CO2 emission and was of the value of 349.02, 42.54, 324.2, -92.07 and -45.50 Mt of CO2 emission and was of the value of 349.02, 42.54, 324.2, -92.07 and -45.50 Mt of CO2 respectively for respective assessment periods. The carbon stock in India’s forest biomass decreased continuously from 2003 onwards till 2015 thereafter; there is an increase in carbon stock from 2569.01 in 2015 to 2643.64 in 2017.Further forest degradation will reduce forest carbon density and hence release of carbon into the atmosphere will enhance leading to global warming. However, proper management of degraded forests and ways to enhance the forest cover will result in significant increase in carbon sequestration by India’s forests and may have more scope during implementation of REDD and REDD + projects and policies.

Abstract: An investigation was carried out on Dendrocalamus strictus for immediate need of bamboo working in Dasuya Forest Division of Punjab. A total of 3, 16,970 clumps were assessed. The study revealed them more than 50 percent of bamboo clumps in this division are dying due to heavy congestion (non working) .Whole of the bamboo forests were divided into bamboo working and bamboo rehabilitation working circles. Though the average percentage of congested clumps come to 54.23, the compartments having less than 50 percent congested clumps were allocated to Bamboo Working Circle and where the congestion was more than 50 per cent, the compartment s were allocated to Bamboo Rehabilitation Working Circle. It was also found that bamboo clumps were getting weak due to invasion of termites and grazing. Regeneration of bamboo was also found very sparse. If the congested clumps are not allocated for working in the present working plan, their quality will be deteriotarated as they get dried, attacked by termites, wind, fire and get decomposed.

Abstract: Non-timber Forest Products NTFPs) are the most accessible forest products of forest dwellers living in the vicinity of the forest areas which are important for their livelihood. In the present study, 10% of total villagers and 10% of total sampled village households were selected in Baria Forest Division (BFD). Apart from this, the house-to-house structured questionnaire survey revealed that forest of BFD yield various NTFPs which are being collected by local people. During the study, a total of 43 types of NTFPs have been identified in BFD having economic value of INR 334.74 million/annum. The study also revealed that maximum economic value comes from leaves (76.25%) followed by flowers and seeds (18.37% ) , fruits (3.18%), herbs and other miscellaneous items (1.26%), gums and tanning materials (0.54%) while the least was recorded from the bamboos (0.37%). Moreover, the estimated per capita value was found to be INR 157.3/annum against the per capita forest area of 0.038 ha. Thus, these NTFPs plays an important role in the improvement of livelihood of forest dwellers living in the forest areas.

Abstract: Forests are a unique gift from nature to man. They are the most biologically diverse ecosystem on land and home of more than 75 % of terrestrial species of animals, birds, plants and insects. They store about 296 Giga ton of carbon and counter climate climate change. They conserve soil, fix nitrogen and add organic matter to improve soil fertility. Forested watersheds and wetlands supply 75% of fresh water. They clean air and water, provide critical wildlife habitat, and make the planet a healthier place to live. Deforestation, climate change, poaching of wildlife, capturing them and their illegal world trade are worrisome. Due to the consumption and exposure of meat from the “wet market” or unnatural reproduction of animals, their deadly viruses are spreading in humans by spreading global epidemics. In the years 2003 to 2019, three global epidemics were encountered. The Covid-19 epidemic has disturbed the entire world. To avoid global epidemics in the future, sustainable forest management and allowing wildlife to live in the forests is absolutely necessary for public welfare.

Abstract: Wood samples of Pinus roxburghii and Populus deltoids were chemically modified by using three different treatments and cured by convection hating at 140˚C for 8 h. The dimensional stability of the modified wood was determined by evaluating anti-swelling efficiency using the water soak/oven dry method. Citric acid modification resulted in better dimensional stability compared to control samples in both the species. The current study indicates that treatment with Citric acid 1.8 % and Sodium hypophosphate 13.0 % resulted in optimal improvement in dimensional stability of wood.

Abstract: A bench mark survey was conducted in March, 2017 to generate information about health status of Palas trees (Butea monosperma) , the most important host tree of rangeeni lac insect (Kerria lacca Kerr.).The principal objective of the study was to identify factors responsible for poor principal objective of the study was to identify factors responsible for poor growth of this important tree. Infestation of termite and trunk borer is perennial problem for Palas trees. Therefore, information was generated under three different conditions (i) tree size i.e. small and big (mean trunk girth 74.3 cm and 151 cm) (ii) land topography i.e upland/lowland and (iii) tree with old/new shoots i.e. trees having shoots of >2 year or one year old. Land topography was found to have effect on termite infestation .In upland condition; termite galleries covered 50 per cent of the tree length, while the same value was merely 5.8 per cent in case of lowland. Smaller trees were 43 percent les infested in comparison to big ones. Similarly, upland trees were 2.5 times more infested than lowland. Number of live shoot and additive shoot diameter per prune point were also found to be higher in case of relatively smaller trees. Number of live shoot per prune point was recorded to be 3.6 and 3.1 in small and big sized trees, respectively and additive live shoot diameter was 52.4 and 43.2 mm per dead shoots were found higher in big sized trees. Only variation was observed in case of trees with old and new shoots. Only variation was observed in case of trees with old and new shoots, where 19.2 percent increase in average diameter was observed in newly emerged shoots i.e. pruned one year back. Better performance of smaller sized trees in terms of growth and pest resistance could be attributed to better rejuvenation power and vitality for being younger in age. Similarly, higher attack of pest in upland soils could be attributed to maintenance of poor health on relatively less fertile uplands.

Keywords: Cedrus deodara, Monoecious, Dioecious, Diplohaplontic, Axuxin, Gibberellic acid
Abstract: The diplohalontic life cycle of conifers with Cedrus deodara, as no exception alternates between reproductive phases and vegetative phase and results in good seed year once in every three to four years interval. The uncertainty of reproduction is not predictable and can be attributed to change in the hormonal levels in the trees at the time o f reproduction. Auxins and gibberellins play major role in flowering of day light plants like conifers, hence an attempt to understand the role of growth hormones leading to the unpredictable behaviour of Cedrus deodara was made, for which over 900 trees were marked at three different sites, viz. Cheog forest, HFRI campus in Himachal Pradesh and Chakrata forest in Uttarakhand and their reproductive behaviour was observed since the time of pollination to cone production. Samples from plants with different reproductive behaviour like, male, female, monoecious and vegetative were collected for extraction and estimation of growth hormones and find out the relationship between the levels of different hormones and cone production, if any.

Subject: Consumer’s preference of Secondary Timbers: Conjoint Analysis
Keywords: Lesser utilized species, Consumer preference, Treated timbers, Untreated timbers
Abstract: Lesser-Utilized Species (LUS) is also called as secondary timbers which can substitute the scarce primary timbers in wood industries. This paper attempts to assess the consumer preference for both treated and untreated secondary timbers. The sample respondents of 130 were selected on a random basis from Coimbatore, Erode and the Nilgiris districts which comprised of sawmills, furniture manufacturing units, builders, and carpenters. The predominant secondary timbers were Neem and Eucalyptus in Coimbatore district, Mango an Vaggi in Erode district and Naval and Silver oak in the Nilgiri district. The choice of decision making to prefer secondary timbers were kind of timber (34.68%), price of timber (23.43%) , the status o treatment (21.9%) and its durability (20.40%) .Non-availability o seasoning units, lack of knowledge on the properties of secondary timbers, quality –related problems in the secondary timbers and presence of substitute products were the major problems for untreated secondary timbers, where as lack of remunerative price, high cost of inputs, lack of credit facilities and lack of awareness about treatments were the major constraints in production of treated secondary timbers.

Subject: Challenges Presented by Pilgrimage sites and their impact on ecology of protected areas: A case study of Ranthambhore Tiger Reserve, Rajasthan
Keywords: Religious tourism, Ecological impact, Disturbance index, Protected areas, Anthropogenic pressure
Abstract: The traditional pilgrimages to religious sites are evolving into large scale religious tourism in many protected areas across India A growing influx of visitors leading to infrastructural development of these sites within protected areas ha potential to immensely damage the natural ecological balance. There are significant changes in the scale and frequency of visits to religious sites over past few decades creating an undue anthropogenic pressure on the ecology of protected areas. The present study tried to estimate the impact of religious tourism on the local ecology inside Ranthambhore Tiger Reserve (RTR) ,India Through direct field mapping and interview based surveys in RTR, 352 religious sites were documented. OUT OF 215 grids of 2x2 km laid down using GIS mapping, 135 (62.79%) grids had religious sites and the accompanying pilgrims in the critical tiger habitat. Disturbance indices for a subsample of randomly selected 42 religious sites were calculated considering ten potential disturbance factors. There was a positive correlation between number of annual visitors to the selected sites (N=42) and the amount of garbage found at the sites. Authors have suggested some measures to reduce the impact of religious tourism on local ecology.

Subject: Diversity and distribution of Hydrophytes and Halophytes in Khijadiya Wetland, Jamnagar, Gujrat (India)
Keywords: Community, Diversity, Halophyte, Hydrophyte, Khijadiya, Wetland
Abstract: Khijadiya is a wetland having two different types of vegetation, i.e. hydrophytes growing in/around fresh water ponds and halophytes growing in/near intertidal mudflats. A study was conducted on the diversity and community composition of hydrophytes and halophytes in Khijadiya wetland. A total of 12 hydrophytes and 10 halophytes were recorded. The fresh water area was dominated by the emergent hydrophytes like Bolbnoschoenus maritimus, Fimbrystylis feruginea and Cyperus difformis where as the Saline habitat was dominated mainly by halophyte (mangrove) species like Avicennia marina. The entire wetland area was endowed with various community groups e.g Bolboshoenus maritimus-Fimbrystylis ferruginea cyperus difformis community (a freshwater community) and Avicennia marina community (a saline water community)
