Keywords: Conservation, Population genetic analysis, Microsatellite markers, SSRs, Cross transferability, Genetic diversity
Abstract: The genetic diversity maintained by Forest Genetic Resources (FGRs) bestow them the capability for survival, adaptation and evolution in response to the changing climatic conditions. Population genetic studies based on DNA based marker may aid in understanding the actual level of diversity and its distribution within and among the populations, gene flow, allele fixation, structure etc. that could be wisely used their conservation and management. Rhododendron campanulatum is medicinally, horticulturally and ecologically important trees species growing at tree line throughout the Himalayas. IN the present study, efforts were carried out to identify simple sequence repeat (SSR) markers in developed in R.arboreum (Choudhary et al), 2014) were tested for cross transferability and polymorphism in R.campanulatum.of these, 12 primer pairs were positively amplified but only 5 (SSR-7, SSR-8, SSR-11, SSR-25 and SSR-9) showed only polymorphism across the populations. Mean polymorphic Information Content (PIC), expected heterozygosity (H6) and observed heterozygosity (H6) of these makers were recorded as 0.609, 0.360 and 0.343 respectively. Other measures such as genetic differentiation (Fst) and gene flow (Nm) were recorded as 0.467 and 0.486, respectively. Population of Valley of Flowers had the highest percentage of polymorphic loci (100%).Analysis of molecular variance (AMOVA) revealed about 25% among the populations and 75% within population. The markers identified in the study could be highly useful for detailed population genetic analysis of this species.

Subject: Growth assessment of young plantation of Santalum album with Dalbergia latifolia a Host
Keywords: Indian sandalwood, Indian Rosewood, Growth, plantation, Heartwood
Abstract: Indian sandalwood (Santalum album) is a highly valued partial root parasite tree and the prized heartwood is considered as 'wood of choice' in carving and oil obtained from stream distillation of heartwood is regarded as 'aroma of choice' in perfume industry. Due to large scale reduction in natural population, it is categorized as 'thretened' by International Union for Conservation of Nature. Earlier it was recognised as Royal tree in Karnataka and Tamil Nadu, because of which even basic information about growth was lacking. With the relaxed government policies and the increased demand for heartwood and soil, farmers and entrepreneurs are motivated to cultivate Sandalwood. Presently, numerous plantations are being raised and documenting growth data from these plantations is very important. During a survey of Sandalwood plantations in Karnataka, an eight-year-old unique sandalwood plantation was identified which had Indian Rosewood (Dalbergia latifolia) as host and growth data was collected. The Sandalwood trees girth at breast height (GBH) varied from 13.9 to 31.2 cm with an average GBH of 19.24 cm and average tree height was 6.02 m varying from 5.0 to 9.5 m. Rosewood had mean tree height and GBH of 8.72 m and 29.18 cm, respectively. Core samples collected from Sandalwood trees above 30 cm girth did not show any indications of heartwood formation. This study would augment necessary information required for developing package and practices on Sandalwood cultivation.

Abstract: Jeypore reserved forest, the remnant patch of the tropical rainforest of Assam, harbours rich diversity of flora and fauna and is facing disturbance due to anthropogenic interventions such as stone and sand collection, coal-mining as well as encroachment for tea plantations in the peripheral areas of the forest. Using geospatial technology, an attempt was made in this study to analyse the changes in vegetation health of the tropical rainforest of Assam due to climate change and anthropogenic intervention over the period 1986-2020.A high positive correlation was observed between the vegetation health and average annual maximum temperature and average winter rainfall were found to be highly negatively correlated with vegetation health of the area. Although there was no significant impact of climate change on the vegetation health of the tropical rainforest of Assam during the study period; climatic parameters of the region in the long run, which in turn may affect the vegetation health of this pristine forest.

Subject: Can we look bee colonies as biological indicators of forest ecosystems?A comparative study of the occurrence of bee colonies in some protected area of Rajasthan, India .
Keywords: Honeybee, Biological indicators, protected areas, Large trees
Abstract: Suvey of colonies Apis dorsata was conducted in five reserves, including Keoladeo national (KNP),Jhalana leopard reserve (JLR), Sariska tiger reserve (STR),Sitamata wildlife sanctuary (SWS), Bassi wildlife sanctuary (BWS), located in semi-arid landscape of Rajasthan. Bee colonies were observed mostly on medium to large sized trees in the study areas demonstrating the role of size o trees irrespective of species type. The observation of high density of bee colonies in KNP (d =7.1 colonies/km2) can be attributed to low intensity of anthropogenic pressures that is evident from low PIPUA (p1=1.68).In contrast observation of low density of bee colonies in STR and SWS (d=0.2, 0.1, colonies/km2) can be attributed to high anthropogenic interference which is evident from the observation of high PIPUA (p1=8.04, 8.08 respectively).Thus, the bee colonies can be considered as biological indicator of forest ecosystem.

Keywords: Forest right act, research, encroachment, implementation
Abstract: The enactment of Forest Rights Act in 2006 by the Government of India elicited jubilation from the human rights activists who believed that times has come to rectify the historical injustice meted out to the tribes and other forest dwellers while there was a sense of foreboding among the conservationists who thought that this Act might result in more encroachments in forest areas and could prove detrimental to the protection of India's depleting wild flora and fauna. Over the course of past 15 years, lakhs of individuals have obtained the right to cultivate and reside in forest lands and over eighty lakh acres of forests have come under community ownership. There also have been several instance of encroachment of forest lands by some people taking undue advantage of the provisions of the act. Efforts are on to recognize other rights under the act apart from individual and community rights, which have been largely neglected. This article explores the various studies on the FRA conducted by different academicians, researchers and reporters from across the country since the Act was promulgated and tries to collate their opinions on the implenetation of the act. Some studies on the implementation of similar initiatives in other countries have also been quoted here.

Abstract: The spatial distribution and floristic composition of an area is the outcome of various environment al factors and needed to be studied for assessing the macro-ecological biodiversity patterns and framing a strategy for biological conservation. The present study was conducted in three Zanthoxylum armatum DC. inhabited sites located in Kathua (Bhaddu and Sukrala) and Udhampur (Dhandal) district of Union Territory (UT) of Jammu and Kashmir (J& K) with the aim of studying the distribution, ecological status, composition, and diversity of overstorey vegetation, especially Zanthoxylum aramtum, and to define the soil attribute/s responsible for these characteristics of vegetation. The results of the study show that aggregate distribution (68.4- 84.2%) was more common than random distribution pattern (15.8 -31.6%).Ecological status of more than 50 % of the species, including Zanthoxylum armatum , was rare in all the three sites. Quercus oblongata, Pinus roxburghii and Pyrus pashia recorded the highest values for importance value index (IVI) in Bhaddu, Sukrala and Dhandal, respectively. As per Dominance-Diversity Curves, the most dominant specie were following the geometric curve and hence were utilizing the bulk of resources in the respective site whereas other species were log normally distributed. Dhandal was the most diverse site having the highest values for species richness (19) and Shannon-Wiener's index (2.59).The Canonical Correspondence Analysis depicted that Zanthoxylum armatum along with Cu at Axis I and available K at axis II were the driving variables responsible for the distribution, diversity, and floristic composition of overstorey vegetation in the present study.

Keywords: Forest dynamics, growth parameters, stratification, forest management
Abstract: The tropical forest is always changing gradually through interactions of the living ecosystem and the environment ; though seems to be static at a given period of time .These changes can be accelerated by anthropogenic effects and the resultant formations are normally unpredictable, but definitely towards the degraded succession stages. The stratification concept in forest is based on difference in tree heights. This difference in heights may be due to site qualities, geographical features, but more prominent due to intrinsic nature of species. The distribution of trees by diameter classes is basic to study tropical forests and is the most accessible and studied information. It is rarely analyzed has not been studied systematically. It makes possible the assessment of the effects of the main environment al factor on forest architecture. The management and modification of tropical rainforest environments, though aimed at controlling dynamic process within a human life span, must take account of the damage of long-term regression or face ultimate catastrophe. The forest dynamics in tropical forest ecosystems are highlighted in the appear.

Abstract: A study was undertaken at Lothian Wildlife Sanctuary of Indian Sundarbans to estimate the stored carbon in the mangrove vegetation of the island.34 true mangrove species were documented from the island, but on the basis of criterion DBH) ≥5 cm, only 26 species were selected for the estimation. We focused on the stem biomass and the carbon locked in this compartment as the other above ground structures (like leaves, twigs and branches) are converted into litter and act as reactively temporary sink of carbon. Stem carbon exhibited direct proportionality with stem biomass in all the species. The total biomass of the documented species (except those whose DBH values are less than 5 cm) was 164.24 t ha-1. The stored carbon in the stem region of these species was 74.18 t ha-1, which is equivalent to 272.25 tons of carbon dioxide. This study concludes the carbon sequestration potential o blue carbon ecosystems such as Mangroves are humongous and can be a potential answer to climate change mitigation.

Subject: Invasion of Alien senna spectabilis (D.C.) H.S. Irwin and Barneby causes Loss of Natural vegetation in the Wayanad Wildlife Sanctuary of India an Edaphic factors of the invaded areas assist its profuse sprouting
Keywords: Senna spectabilis (DC) H.S.Irwin an Bameby, Muthanga, Tholpetty, Invasion, Sprouting
Abstract: The Indian region because of its diverse climatic and environment al conditions is highly vulnerable to biotic invasion. In the Wayanad Wildlife Sancturary of India authors studied the effect of the invasion one of the alien species, Senna spectabilis (DC) H.S.Irwin and Barneby, on natural vegetation and analyzed whether the edaphic factors of invaded regions induce its profuse sprouting. Authors observed that the invasion of S.spectabilis Leds to drastic loss in the natural vegetation there. No ground cover was found in the invaded region whereas heavy sprouting of S.spectabilis seeds was detected. The reappreance of lost flora with high diversity and species richness were noticed in the regions where S.spectabilis were manually eradicated. A study on the seed germination under laboratory conditions showed that the seeds of S.spectabilis are highly dormant and scarification using concentrated H2SO4, or water incubation induces its germination. Further analysis of soil samples of the invaded area revealed that soils are acidic and have high water holding capacity. The results imply that the invasion of S.spectabilis is a major threat to the indigenous plant diversity and edaphic factors of the invaded areas assist the profuse sprouting.

Subject: Host density influence on Reguarly fallen ichen species in temperate forests of Kumaun Himalaya
Keywords: Regularly fallen lichen species,Biomass,Density,Hosts, Temperate Forest
Abstract: Lichens are very slow growing plants and play a significant role in forest ecosystem. In temperate area lichens occur abundant on Quercus trees. After falling down lichens decompose int the soil and contribute to nutrient cycling. In present study nine regularly fallen lichen species were recorded in three altitudinal zones. The density of fallen lichen was found maximum 95625 ind. ha-1 yr-1 at lower altitude followed by 70125 at higher altitude. The lichen biomass ranged between 5375 g ha-1 yr-1 to 7862.5 g ha-1 yr-1 (11687 g ha-1) of fallen lichens was recorded in summer followed by 3198 in winter and 2950 during rainy season. Minimum biomass was recorded in the spring season of about 2262 g ha-1. Similarly, annual highest biomass of fallen lichens was measured 7862.5 g ha-1 at lower altitude. Quercus leucotrichophora, Pinus roxburghii and Rhododendron arboreum trees were observed as luxuriant lichens particularly in lower altitude. Lichen taxa Parmotrema praesorediosum (foliose lichen) contributes a highest 85.37% biomass of all species at lower altitude. At higher altitude R.conduplicans (a fruticose form of lichen) contributes maximum 31.13% followed by foliose growth forms P.tinctorum (27.70%) and E.cirrhatum (19.31%) of the total fallen lichen biomass.

Subject: Carbon pool in Quercus lanuginosa (D.Don) Foret of Askot Wild life Sanctuary,Western Himalaya in relation to stand Attributes
Keywords: Carbon stock,disturbance , forest structure, oak forests, regeneration, soil
Abstract: Following the acceptance of the Kyoto Protocol, data on forest biomass must be collected in order to determine the potential ability of forest stands to sequester atmospheric carbon and aid in the reduction of rising carbon dioxide levels in the atmosphere. The aim of this study was to estimate the amount of carbon fixed by one of the over exploited oak species (Quercus lanuginosa) in Askot Wildlife Sanctuary Western Himalaya, India. Thirty quadrats of 10x10 m size were placed randomly at three altitudes between 1900 and 2200 m asl, and data on biomass and soil characteristics were collected.In three forest sites, CBH (circumference at breast height) o 236 individuals with a diameter of ≥30 cm was measured and standing biomass was estimated folowing growing stock volume equations.Across the sites, the maean aboveground and belowground carbon stock were 475.8 ±84.9 and 119.8 ±18.1 Mg C ha-1, respectively.The total tree crbon stock showed a significant (P<0.01) positive correlation with organic carbon (R2 =0.71 ) and total nitrogen (R2=0.99).The basal area showed significant positive, while diversity showed a significant negative correlation with carbon stock. High carbon accumulation potential in old-growth individuals of Rianj oak suggests that they should be maintained in the study area to mitigate the effect of climate change.
