Item World heritage biodiversity programme for India(Wildlife Institute of India, Dehradun, 2003) Mathur, V.B.; Krishnaswamy, Jagdish; Singsit, S.; Bawa, Kamajit S.; Ishwar, N.M.; Vanak, Abi TamimIndia, one of the earliest signatories to the World Heritage Convention has five key Protected Areas currently on UNESCO’s World Heritage List - Kaziranga and Manas in Assam, Keoladeo Ghana in Rajasthan, Sundarbans in West Bengal and Nanda Devi in Uttaranchal. All five sites satisfy the natural heritage criterion ‘contain the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science and conservation’ (iv) and hence are critical to the preservation of globally Significant biodiversity. A strong potential exists to build and to strengthen the constellation of India’s World Heritage Biodiversity (WHB) sites in ways that are exemplary and beneficial for the larger network of PAs in India and abroad. The World Heritage Convention also offers a unique possibility in India to link nature and culture in innovative ways to promote conservation of species like the tiger and the elephant at a nation-wide scale. India presents the greatest challenge anywhere in the world for integrating conservation and development on a grand scale, and success here could have major implications for other parts of the developing world. The WHB sites symbolize humanity's struggle to conserve the earth's precious biological heritage against its own onslaught of nature. Combined with other Protected Areas such as National Parks and Wildlife Sanctuaries, WHB sites represent the last stand of the nature and the best hope for humanity to conserve our most precious endowment. India represents a remarkable example of successful efforts to conserve significant amounts of biodiversity against all odds. Despite the presence of more than one billion people, India has managed to place 154,826 km? of its land area under its PA network. Considerable amount of biodiversity also occurs in habitats outside protected areas. Furthermore, protected areas in India are among the best-managed reserves in the developing world. The WHB sites and other Protected Areas in India, however, remain highly vulnerable to degradation. As islands, these areas are surrounded by harsh biophysical landscapes and alienated local communities. The PA management is not fully equipped to deal with the growing threats to the parks. The staff is inadequately trained in the enforcement of laws protecting wildlife. In some cases such as Manas in the northeast, field staff is demoralized, having suffered setbacks due to insurgency and social turmoil in the area. Moreover, the field staff have neither access to good communications nor to facilities for health and education for themselves and their families and the basic infrastructure required for the effective management of the PAs are generally lacking. World Heritage Biodiversity Programme for . At higher levels, the park management has been unable to incorporate concepts of conservation science and wildlife management in developing management plans. Since parks represent habitat islands surrounded by dissimilar habitats with high densities of human populations, changes inside the park due to intrinsic and extrinsic factors are inevitable. However, there is no significant effort to adopt a systems approach to anticipate and predict future changes. Continuous assessment and monitoring of biodiversity are almost non-existent. The "island" status of the World Heritage sites also makes them highly vulnerable to anthropogenic pressures. Although these islands are connected to varying degrees with other natural habitats, there have been no comprehensive efforts to examine the feasibility of establishing habitat connectivity in areas containing the WBH sites. Since the areas surrounding sites are even more vulnerable to human pressures than the WBH sites, it is critical to examine the potential of connection among natural areas wherever these sites are located and to bring these areas under greater protection. A more serious problem is the lack of local community involvement in conservation efforts. Local communities in many cases remain hostile to the idea that the parks cannot be used for their traditional purposes of grazing, fishing, or extraction of fuel wood and non-timber forest products. Wild animals from the parks also pose a danger to their livestock, crops and houses, thus exacerbating the conflict. Thus, local communities perceive conservation legislation as a threat to their livelihoods. Although there are economic benefits from conservation, such as ecotourism, such benefits generally do not accrue to local communities. Protected areas also have a low profile. The civil society in general is not aware of the importance and in some cases even the existence of World Heritage sites. Although the protected areas have a tremendous educational potential, educational institutions hardly ever use world heritage sites for educational purposes. A new initiative funded by the United Nations Foundation (UNF) and United Nations Educational, Scientific and Cultural Organization (UNESCO) and coordinated by the Ministry of Environment and Forests, Government of India initially covering four existing and ten proposed World Heritage Cluster Sites in India has been initiated to address the key conservation and management issues within a single new framework. This framework referred to as the ‘World Heritage Biodiversity Programme for India (WHBPI)’ has been developed through a collaborative planning process by the, Wildlife Institute of India (WII) and the Ashoka Trust for Research in Ecology and the Environment (ATREE). The ten year WHBP' will have two phases of four and six years each. Four of the existing five WHB sites in India namely Kaziranga, Keoladeo, Manas and Nanda Devi National Parks have been included in the WHBPI. programme as it is receiving a similar support from the Asian Development Bank under the ‘Sunderbans Biodiversity Project’. The goal of the WHBPI is to strengthen biodiversity conservation in Protected Areas by \ building replicable models at WHB sites that emphasize law enforcement, promote habitat integrity and connectivity, enhance the role of local communities in Protected Area management, improve the professional, social and political profile of the Protected Area management community and its civil society partners. The specific objectives of WHBP! are to: 1) increase the capacity of the staff to address critical needs in conservation, management and protection of the WHB sites, (2) enable the . park staff to incorporate principal concepts of modem science in management plans, (3) increase the connectivity among natural areas in the vicinity of the WHB sites, (4) enhance the stake and the involvement of local communities in the management and the protection of the parks, (5) raise the profile of the WHB sites in civil society, (6) bring about policy and governance reforms so that the management have the flexibility to address contemporary challenges to the conservation of biodiversity in the parks, and (7) conduct surveys at sites that may be designated as additional World Heritage. Biodiversity cluster sites.Item Priority areas for ecological assessment along samruddi corridor, Maharashtra, India: preliminary report(Wildlife Institute of India, Dehradun, 2019) WIIGlobal conservation strategies depend strongly on the creation and strengthening of the protected area network. However, several protected areas are facing new challenges of development In their surroundings leading to habitat f fragmentation and species loss. Roads are essential transport infrastructure to support India's endeavors of fulfilling vital transportation needs across the country. In the last decade, negative impacts of road network has been significant. .Special attention. is therefore required to protect wildlife values like corridors and distribution ranges of wildlife species that overlay the alignment of the expressway. The task, therefore, is to foresee conservation beyond protected areas that undergo modification due to growing infrastructural development, which eventually exerts pressure on protected areas. Maharashtra State Road Development Corporation (MSRDC) has proposed to build a smart green expressway connecting Nagpur to Mumbai. The highway aims at strengthening the rural agriculture sector while enhancing mobility. Although, the proposed alignment does not cross through any existing protected areas nevertheless MSRDC has envisaged developing the road as wildlife friendly infrastructure aiming at conservation outside protected area network. The objective of this report is to assist MSRDC and Government of Maharashtra in addressing ecological concerns at an early stage of planning the highway for safeguarding wildlife values. The preliminary report by the Wildlife Institute of India provides a framework for the protection of wildlife along the proposed alignment (701 km) of Nagpur Mumbai expressway, Maharashtra, India. This report aims at developing a roadmap to assess and evaluate ecological implications of future road development in the landscape with special emphasis on wildlife corridor function. Relevant mitigation measures shall avoid these impacts (direct, indirect and cumulative) of road infrastructure on various wildlife taxa and their habitats within the three landscapes of Maharashtra. The consecutive assessments conducted post this report will provide a strategic mitigation plan to present and minimize impacts of the proposed expressway on ecological habitats and wildlife. The Nagpur-Mumbai expressway is planned to be the first of Its kind project, where mitigation measures for wildlife are planned before? the road is built. This report helps in identifying the Important wildlife habltats that may require further assessment to design appropriate mitigation structuresItem Supplementation of Gaur in Bandhavgarh Tiger Reserve, Madhya Pradesh(Wildlife Institute of India, Dehradun, 2025) Nigam, Parag; Gorati, A.K.; Vishwakarma, R.; Bhandari, B.; Habib, Bilal; Mondol, Samrat; Nath, A.; Sen, S.; Krishnamoorthy, K.; Sahay, A.; Nanda, R.; Tiwari, V.R.Reintroduction and supplementation programs have been implemented worldwide to improve the conservation status of wildlife that have experienced a significant decline due to overexploitation, habitat destruction and fragmentation. Genetic drift and inbreeding are the two processes particularly relevant in reintroduction efforts that lead to reduced fitness, deceased survival rates and increased susceptibility to diseases. The MPFD in collaboration with WII has initiated a three year project (2024-2027) titled : Population management strategies for gaur (Bos gaurus gaurus) conservation: supplementation of gaur in Bandhavgarh tiger reserve, Madhya pradesh''. This project aims to ensure the long term viability of the species by enhancing its genetic diversity. To facilitate the smooth execution of field operations, an action plan was developed and released during the Inception cum planning workshop held at Bandhavgarh Tiger Reserve. Conservation translocation have become an important tool in recovering the threatened and locally extinct population. Species translocation are increasing all around the globe to reverse biodiversity loss and restore ecosystem functions. Reintroductions require careful planning as small population size experience inbreeding depression, which leads to decreased fitness and demographic stochasticity. Although genetic diversity is not directly linked to species extirpation, low gene pool results in low species recovery. To enhance the gene pool and long term viability of the restored species, supplementations are crucial, especially in small and isolated populations. The addition of new individuals amplify the gene flow in reintroduced species.Item Unveiling Torputitora presence in Sikkim streams through eDNA(Wildlife Institute of India, Dehradun, 2025) Mane, S.S.; Pant, B.; Kolipakam, VishnupriyaEnvironmental DNA (eDNA) metabarcoding was used to detect the presence of Tor putitora (Golden mahseer) in selected streams of Sikkim. Water samples were collected from six sites based on habitat characteristics conducive to the species survival. The collection of samples was followed by filtration of water samples, isolation of the DNA, PCR and sequencing targeting the COI region were conducted under aseptic conditions. The results confirmed Tor putitora presence at two locations (BR-06 and BR-08) with high certainty (>99%) aligning with previous studies on tis distribution in Sikkim. These results indicate that these streams serve as habitats for Tor putitora. These findings highlight the potential of these streams to support mahseer populations, reinforcing the need for conservation efforts to protect these critical habitats from ecological threats like ecological pressures, including hydropower and linear infrastructure development. This study adds to the expending evidence concerning mahseer distribution in Sikkim and highlights the critical need for conservation initiatives aimed at safeguarding its essential habitats by incorporating appropriate mitigation measures. Continued research and long term monitoring are imperative to evaluate population dynamics and ensure the sustainable management of Tor putitora in the region.Item Ecology and conservation of the Grasslands of Eravikulam National Park, Western Ghats(Wildlife Institute of India, Dehradun, 1998) Karunakaran, P.V.; Rawat, G.S.; Uniyal, V.K.An ecological study on the montane grasslands of Eravikulam National Park (ENP), the Western Ghats, was conducted during 1992-1996, with the following objectives: (i). to prepare a complete floristic inventory of the grasslands of ENP, (ii). to identify the grassland communities, their structure, function and successional trends along the anthropogenic gradient, (iii). to determine the forage quantity in different ecological conditions and (iv). to study the effect of fire and tree plantations on the grasslands. : The ENP lies between 10° 5' to 10°20' N and 77° to 77°10' E with an area of 97 km? in the Southern Western Ghats. The average altitude of the plateau is 2000 m and the highest peak, Anamudi, reaches 2695 m. Soil was acidic with pH ranging from 4.6 to 4.8. The climate was dominated by monsoon. During the study period the annual rainfall ranged from 4697 to 5540 mm. Winter days (Nov- Jan) were cooler and frost was common. The two distinct physiognomic units of vegetation are grasslands and sholas, unique to the Western Ghats. 3: The study area was stratified into eight landscape units viz., slope without rocky outcrops, slope with rocky outcrops, flat top, valley, bog, shola-grassland edge, cattle grazed and scraped areas. Systematic surveys and vegetation parameters such as species association, frequency, diversity, evenness and richness were studied in each landscape unit by laying 5 m radius. 4. 308 plant species were collected from the grasslands, adding 106 new species to the earlier list. 51 species were found to be endemic to the grasslands and 29 were listed as rare and endangered species. There were 64 species common with Eastern Ghats, 30 species with Patanas of Sri Lanka, 35 with Western Himalaya and 35 with Naga and Khasi hills indicating phytogeographical affinities with different biogeographic zones. D! Vegetation association was derived using ‘TABLE TRANSFER METHOD’ and TWINSPAN (computer packages). TABLE TRANSFER method identified 23 vegetation associations and TWINSPAN identified 15 associations. In both the analyses it was found that Chrysopogon zeylanicus and Sehima nervosum were the two dominant species. The diversity index (H’) of the associations ranged from 1.38 in the Artemisia nilagirica-Heteropogon contortus-Cymbopogon flexuosus (cattle grazed area) to 2.90 in Agrostis peninsularis-Eulalia phaeothrix-Chrysopogon zeylanicus in the shola-grassland edges. Vegetation ordination i.e., Canonical Correspondance Analysis (CANOCO) indicated that clay, pH and sand were important environmental factors which determined the species distribution and abundance.6. Biomass study was conducted at three sites in three dominant communities viz., Chrysopogon zeylanicus, Sehima nervosum and Cymbopogon flexuosus. Clipping was done both inside the exclosure and outside to obtain net primary productivity (NPP). The NPP values showed that these grasslands are between tropical and temperate grasslands . Outside the exclosures NPP was maximum at Eravikulam and minimum at Lakkamkudi. But inside the exclosures all the three sites were having nearly equal amount of NPP. Above ground biomass (ANP) was maximum at Eravikulam inside the exclosures and less at Rajamala, where as below ground (BNP) biomass was more at Rajamala and less at Lakkamkudi. Rate of biomass production was more (3.1 g m day!) at Eravikulam inside the exclosure and less (0.8 gm? day!) at Lakkamkudi outside the exclosures. In all the communities monocots contributed more to the ANP (59-97 %) than dicots (3-41%). In Lakkamkudi Pteridium aquilinum (fern) contributed 10 % to the ANP. Sehima nervosum, Heteropogon contortus and Chrysopogon zeylanicus were the three dominant grass species according to ANP. The annual removal of ANP by cattle and wild ungulate from Lakkamkudi was 68 %. Z. Burning (early and late) was done in S. nervosum (Anamudi) and C. zeylanicus (Rajamala) community. It was found that both in the early and late burnt areas no significant changes were noticed on species diversity, richness and evenness. Regarding the structure of the vegetation, cover value of dicots showed significant difference between early and late burnt in different months. Both early and late burning affected the regeneration of Phlebophyllum kunthianum. 8. A comparison of various sites with different density and age of wattle plantations with unplanted area showed that the number of endemic species and food species of Nilgiri tahr decreased with increase in the age of plantation. The increase in weed abundance with the age of plantation indicated more harm to the natural vegetation. The diversity index (H’) was 2.64 in 10 year old plantation and 1.87 in 3 year old. TWINSPAN identified two plant species associations each in unplanted, 3 year old and five year old plantations, and four in 10 year old plantation. 9. The study recommends the following research and management strategies for the long term conservation of Shola-Grassland ecosystems and endangered Nilgiri tahr: (a) inclusion of adjecent reserved forests with shola-graslands in the park, (b) boundary verification and better patrolling to check the illegal activities and fire hazards, (c) early burning in selected areas on experimental basis, (d) control of black wattle spreading, (e) eco-development measures for the Lakkamkudi village, (f) better tourism management and (g) long term monitoring of exclosures and representative shola-grassland patches.Item Patterns of Mortality in Free Ranging Tigers(Wildlife Institute of India, Dehradun, 2016) Nigam, Parag; Muliya, S.K.; Srivastav, A.; Malik, P.K.; Shrivastava, A.B.; Mathur, V.C.This study initiated an effort to maintain a centralized database of all tiger mortality events that are reported in India to address this shortcoming. We have initiated an attempt to study mortality patterns of tigers inhabiting landscapes in India based on available reports of mortality events in tigers from this databaseItem Management of Forests in India for Biological Diversity and Forests Productivity, A New Perspective - Volume IV : Garo Hills Conservation Area (GCA)(WII-USDA Forest Service, 2002) Kumar, A.; Gupta, A.K.; Marcot, B.G.; Saxena, A.; Singh, S.P.; Marak, T.T.C.The principal aim of the project was to demonstrate an approach to achieving integration of concerns in India for biological diversity, forest based products, and their sustained flow in support of technological, economic and social benefits to urban and rural sector lifestyles. To accomplish this, the project set forth the following six objectives that addressed ecological assessment in “conservation areas” that included relatively undisturbed forest ecosystems, managed forests with current forestry interventions under a variety of harvest systems, and intervening matrix landscapes that support subsistence and related market based rural economies.Item Management of Forests in India for Biological Diversity and Forests Productivity, A New Perspective - Volume III: Anaimalai Conservation Area (ACA).(WII-USDA Forest Service, 2002) Sajeev T.K.; Srivastava, S.K.; Raphael, Martin G.; Dutt, Sugato; Ramachandran, N.K.; Tyagi, Praveen C.The principal aim of the project was to demonstrate an approach to achieving integration of concerns in India for biological diversity, forest based products, and their sustained flow in support of technological, economic and social benefits to urban and rural sector lifestyles. To accomplish this, the project set forth the following six objectives that addressed ecological assessment in “conservation areas” that included relatively undisturbed forest ecosystems, managed forests with current forestry interventions under a variety of harvest systems, and intervening matrix landscapes that support subsistence and related market based rural economies.Item Management of forests in India for Biological Diversity and Forests productivity, A new perspective - Vol. VI : Terai Conservation Areas (TCA)(WII-USDA Forest Service, 2002) Kumar, H.; Mathur, P.K.; Lahmkuhl, J.F.; Khati, D.V.S.; De, R.; Longwah, W.The principal aim of the project was to demonstrate an approach to achieving integration of concerns in India for biological diversity, forest based products, and their sustained flow in support of technological, economic and social benefits to urban and rural sector lifestyles. To accomplish this, the project set forth the following six objectives that addressed ecological assessment in “conservation areas” that included relatively undisturbed forest ecosystems, managed forests with current forestry interventions under a variety of harvest systems, and intervening matrix landscapes that support subsistence and related market based rural economies. Project Objectives : • Assess, document, and map the kinds, extent and distribution of plant and animal diversity in selected ”conservation areas” through rapid survey methods.• Use existing status and habitat relationships information to set up baseline habitat relationships information system. • From stand-to landscape-level perspectives, evaluate the impact of existing forestry practices and use of forest-based resources by local people, including methods of harvests and collection, fires, operation of varied concessions and rights on micro habitat elements, key habitats, species, communities, the overall forest productivity and diversity. • Rapidly assess the social and economic systems of surrounding villages in terms of varied land use and forest resource dependency, including raising and grazing of domestic livestock, other vocations, skills, economy, and markets. These will be seen in relationship to forest systems. Threats to ecological harmony and economical status of people will be documented. • Use modern ecological concepts to develop practical management tools and practices for bringing about harmony within and between forest and village systems through sustainable land use practices that make social and economic sense. Document problems and threat mitigation prescriptions, and develop site specific field guides to management. • Conduct workshops and seminars to share experiences, disseminate knowledge, and begin the process of training scientists and managersItem A Preliminary Study on the Ecology of the Leopard, Panthera pardus fiisca in the Sanjay Gandhi National Park, Maharashtra(Wildlife Institute of India, Dehradun., 1998) Edgaonkar, Advait; Chellam, RaviA preliminary study of the ecology of the leopard, Panthera pardus fusca, was done at Sanjay Gandhi National Park (SGNP) in Maharashtra. The diet of the leopard was determined by analysing leopard scats. The major prey of the leopards was found to be domestic dogs, domestic buffalos and rodents. Primates, including rhesus macaques, bonnet macaques and common langurs and cervids, comprising chital, sambar and barking deer were also preyed on. Sections of 8 dirt roads, termed as trails T1 to T8, were monitored for intensity of leopard use. An index of prey abundance, human disturbance, stalking cover and density of trees along the trails was calculated. Intensity of use of trails by leopards was not related to the measured habitat parameters of the trails. Instances of leopard-human conflict was analysed using secondary records of the Maharashtra State Forest Department from 1986 to 1996. It was found that most instances of conflict occurred in summer and monsoon seasons. Seventy eight per cent of the deaths were of children. Awareness about leopards and attitudes towards them were quantified using a questionnaire. Tribals showed a more positive attitude score than non tribals. No such difference was seen far awareness. There were no differences in awareness and attitude among literate and illiterate people. A positive correlation between awareness scores and attitude scores was found. Suggestions for the management of leopards in SGNP include the experimental augmentation of the prey base with wild caught ungulates, monitoring for domestic dog transmitted disease, avoiding reintroduction of leopards trapped on the periphery and outside the Park boundaries into the Park and monitoring far inbreeding depression by comparing the percentage of abnormal sperm in samples from male leopards in SGNP with those from a larger population of free ranging leopards elsewhere in the country.
