    Aspects and determinants of human-carnivore conflict in tiger corridors of Terai, Western Circle, Uttarakhand
    (Wildlife Institute of India, Dehradun, 2024) Ranjan, Vivek; Badola, Ruchi; Dhakate, Parag Madhukar
    Human-wildlife interaction with negative consequences, commonly termed Human- Wildlife Conflict (HWC), is a global conservation challenge. Understanding the cause-effect relationship resulting in HWC is essential to resolve and mitigate the conflict and promote human-wildlife coexistence. However, the increasing human population and rapidly changing demography severely affect the contiguity of forested landscapes and habitats, becoming a major challenge for conserving wide-ranging large mammals. The conservation and protection of wildlife corridors are vital for the survival of wide-ranging large mammals in the landscape. The Terai landscape, located in the foothills of the Himalayas and proximate plains of the Indian Himalayan Region, is one of the most significant and distinct transboundary landscapes worldwide. In recent decades, the Terai region has recorded a rapid increase in human population and industry growth due to its conducive topography for industrial development in the hilly state of Uttarakhand. The region is also home to diverse wildlife, and increased conservation efforts and protection have yielded positive results, with an increased population of endangered wildlife species like tigers in the last few years. With increasing population and shrinking wildlife habitat, human and wildlife's peaceful and sustainable coexistence is distressed, leading to an increased probability of negative human wildlife interaction. The study aims to assess the aspects and determinants of Human-Large Carnivore Conflict (HLCC) in the wildlife corridors and their adjoining habitats in the eastern terai landscape of Uttarakhand state of India. The large carnivores considered for the purpose of this study are tiger and leopard only, which are common in the landscape of the study area. The study has three objectives: to assess the nature and extent of human-wildlife conflict due to large carnivores, the habitat structure and composition of the wildlife corridors and the diet preferences and consumption patterns of large carnivores in the corridor habitat. The thesis has been divided into six chapters, where the first two chapters are a general introduction and literature review, and the following four chapters talk about socio-ecological factors, habitat quality of corridor habitats, implications of habitat changes on HLCC, and diet profile of two sympatric large carnivores of the study area, i.e. tiger and leopard. The study area is part of Terai Arc Landscape (TAL), a Tiger Conservation Landscape (TCL_Id-44) of global importance with the potential for increasing the wild tiger population. The study was conducted in the delineated wildlife corridors for large mammals in the terai landscape of Uttarakhand state of India. The study focuses on the critical wildlife corridor in high tiger density and transboundary areas, providing crucial connectivity of habitats and wildlife populations. The study area is divided into two study blocks for the spatial convenience of the study: Block 1 comprises the Kosi Corridor, and Block 2 comprises theKilpura-Khatima-Surai (KKS) and Boom-Brahmadey (BB) corridor and their adjoining forests. Kosi corridor connects Corbett Tiger Reserve to Pawalgarh Conservation Reserve in Ramnagar forest division. The KKS and BB corridors in Block 2 have contiguous and interconnected habitats adjoining Nandhaur Wildlife Sanctuary in the Haldwani Forest Division of Uttarakhand, connecting to Pilibhit Tiger Reserve and Sukhlaphanta National Park through forest of Nepal. The study area is rich in faunal diversity and home to a few important large mammals, such as the Tiger, Leopard and the Asian elephant. In order to understand the nature and extent of HLCC in the landscape, it was essential to understand the socio-economic conditions and perceptions of the communities. We conducted random household (HH) semi-structured questionnaire surveys and discussions in the villages located in the corridors. The information on HWC compensation records was also collected from the Uttarakhand Forest department to analyze the patterns of conflict incidences. The results show that livestock grazing, fuelwood, and fodder collection from the forest are common and prevalent practices. About 90% of the households have LPG connections at home, yet most HH members still visit forests for collection. The education level among the respondents is low, with maximum HHs having an annual income of less than one lakh. The major occupation as the primary source of income in the study area is casual labour work, and most of the HHs have land holdings of less than an acre. The incidences of HLCC mainly occurred inside the forest areas and later half of the daytime, i.e., from noon to evening. The season of incidence and condition of the body of the depredated livestock show significant association with the place of incidence. The seasonality pattern of HLCC incidences shows nan incidents during monsoon in study block 1, whereas in block 2, it is in winter. The trend of incidences over the last 13 years in study block 1 shows a peak in tiger and leopard cases during July and August and forecasts an increase in cases over upcoming years. The annual trend of HLCC in the two study blocks is significantly different. The nature of HLCC in the study area is both tangible, which can be visually observed and intangible, which has imbibed effects with direct and indirect impacts. The tangible nature of large carnivore conflict is the direct impacts in the form of human casualty and livestock depredation. The intangible nature of the conflict with indirect impacts are psychological— fear of large carnivores and sense of insecurity, social — loss of livelihood and family security. The aspects of HLCC are socio-ecological, with both the social factors of communities residing around the forest and the ecological processes influencing the HWI. In rapidly transforming human-dominated landscapes, anthropogenic activities and disturbances significantly impact the ecological processes and landscape characteristics. The habitat quality was assessed using the nested quadrat method for vegetation and camera trapping for large carnivore population estimation and prey availability. The camera trapping was done using the capture-recapture method in 2 sq. Km sampling grids. The results show maximum tree diversity in the BB corridor, with good to fair Sal regeneration in all three corridors. However, most of the tree species show poor to no regeneration. Sixty-one species of trees were recorded from the three corridor areas sampled. As an invasive plant species, Lantana camara is more prevalent and extensive in study block 1 and Ageratina adenophara in block 2. The grassland habitat is shrinking, and less in all three corridor habitats.Anthropogenic disturbance is high in block 2 in comparison to block 1, while tree cutting and lopping are the most prevalent anthropogenic disturbance signs observed in all three corridors at equivalent levels. The medium-sized prey is the most abundant prey base in both the study blocks, with maximum relative abundance of Spotted deer. However, the relative abundance of Sambar deer is higher in the bhabar topography area of corridors and maximum in large sized prey. The study block | has 16 adult tigers and 22 leopards, while block 2 has 31 adult tigers and 40 leopards. The wildlife habitats of the three corridor areas studied have good tree diversity and complexity. However, the regeneration of tree species is poor for most species. The shrub and herb cover are also low for most areas in all three corridors, affecting the lower structure of forest habitats. The extensive growth of weed species like Lantana camara and Ageratina adenophora also affects understory species' composition, structure, and tree regeneration. The poor regeneration and deteriorated lower strata vegetation with sparse undergrowth are unfavourable conditions for breeding large carnivores, which requires dense patches for hiding their offspring. The lack of such patches and high human disturbance forces them out of the forest to use sugarcane farm fields to raise and hide their young ones, as has been observed in many instances in the Terai-Bhabar landscape. Using human-modified landscapes by large carnivores for their life cycle stages is unsuitable for human-wildlife coexistence and increases the vulnerability of negative HWI. ASS Bind Expert in CC EE TTT The implications of habitat transformations on HLCC were assessed by identifying spatial conflict hotspots based on compensation records of the last 14 years and the magnitude of incidents related to large carnivores in different locations. The Land Use Land Cover (LULC) and Enhanced Vegetation Index (EVI) change over twenty years were assessed. The Nighttime Light (NTL), an indicator of human growth and activity centres, was also assessed for a decadal change. The impact of changes in these habitat attributes on hotspots was assessed using the Generalized Linear Model. The model shows that the impact of vegetation health change and human activity or disturbances have a significant effect on conflict hotspots. The very high-risk zones are also located in the delineated corridors near bottleneck areas. The study has highlighted that the implications of habitat changes are significant for HLCC. The implications of habitat changes vary with the landscape and regional attributes, as observed in our study at two sites with varied underlying factors other than habitats. In the present conservation paradigm of large carnivores, it is essential to understand the feeding habits and prey-predator dynamics outside protected areas. Our study fills this gap in our understanding of the dietary habits of sympatric large carnivore species outside protected areas (PAs) in the terai landscape of India. It focuses on the feeding ecology of tigers and leopards in wildlife corridor habitats outside PAs. Our results show a significant dependence of tigers and leopards on medium-sized prey, i.e., Wild boars and spotted deer. It also shows a 93% overlap between tiger and leopard diets in the study area. However, it is crucial to augment wild prey availability in the wildlife corridor habitats, where grazing pressure is high. The problem of stray cattle has further escalated the issue of livestock depredation by large carnivores. Conservation strategists must consider the feeding habits of the predators and how these are changing due to the induced effects of anthropogenic activities.

    Storied Landscapes : A Study of the Ecological Narratives of the Bhotiyas (TOLCHHAS, MARCHAS AND JADS) of Uttarakhand
    (Wildlife Institute of India, Dehradun, 2021) Saurav, Devshish; Badola, Ruchi; Baroth, Anju
    Himalaya is still young and growing; the formation of Himalayan ranges is still going on Vast terrain, unstable stretches, extreme climatic conditions and other potential hazards are major challenges for the inhabitants of the area. Humans have survived all such challenges since ages, it is a story of settlers’ survival and sustainability. The story of survival narrates the suitability of the wise traditional practices and sustainable community based approach. This process follows the lessons learnt from trials and errors, cultural assimilation and devoted observations. This is reflected in socio-cultural spheres, technological understanding and institutional structure of local Bhotiya (Jads, Tolchha, Marcha) society.It is important to understand the Himalayan settlers historically, the cultural practices of inhabitants help us in understanding the background, origin and nature of local traditions. Jads,Tolchhas and Marchas are such ethnic groups from Uttarakhand who evolved and settled in Himalayan region over a course of time. They follow different cultural traits, livelihood practices and hold different socio-political and religious affiliations. They inhabit the northern and upper ranges of Himalayas. The blend of Tibetan Buddhism and Hinduism is reflected from their culture and nomadic lifestyle. Since very old time the Middle Himalayan region of Garhwal and Kumaun have been under the influence of Hinduism.

    A study on the resource dependence, human-wildlife conflict and community participation in forest management in Alaknand basin, Uttarakhand.
    (wildlife Institute of India, Dehradun, 2018) Manral, Upma; Hussain, S.A.; Badola, Ruchi
    Himalayan mountains are highly dynamic systems with both natural and anthropogenic disturbances acting as integral drivers of natural system dynamics in the region. The consequent changes brought into the system determine ecosystem productivity and the flow of ecosystem services to the humans. Any degradation of ecosystem functions and services will increase both the environmental and socioeconomic vulnerability of mountain communities which are highly reliant on natural systems, particularly forests of the area. The objectives of the study were to: a) quantify the extent of extraction of plant resources in different villages located at different elevations; b) assess the availability of major phyto-resources in and around the villages and surrounding forests along elevational gradient in the Alaknanda river basin; c) assess the extent of human-wildlife conflicts affecting the livelihood in the study area; and d) measure the contribution of community forest management practices in livelihoods of local communities. Four hypothesis were framed as: a) patterns of both availability and the extraction of forest resources in the study area xi change along the elevational gradient; b) human–wildlife conflicts negatively impact livelihood generation of affected communities; c) community forest management practices play a role in augmenting livelihood of local communities in the area; and d) better managed forests in an area are the result of community participation in forest management

    Assessment of provisioning service and the recreational value of Nanda Devi Biosphere Reserve.
    (Wildlife Institute of India, Dehradun, 2015) Pariva; Hussain, S.A.; Badola, Ruchi
    The ecological services and the natural capital stocks that produce them are critical to the functioning of the earth’s life-support system. Because of the direct use of the structural value provided by natural ecosystems and in most cases of free access to such ecosystems they are under heavy utilization pressure. The harmful effects of degrading ecosystem services are being disproportionately borne by the poor and are contributing to the growing economic inequities as well as environmental hazards to which the poor are the most vulnerable. Present work aimed to understand the status of the provisioning and recreational services of the Nanda Devi Biosphere Reserve (NDBR) and their contribution in securing wellbeing of local communities. The study was carried out with five objectives: (a) assess the socioeconomic status of local communities in NDBR, (b) quantify the provisioning services of the Reserve in terms of resource extraction, (c) estimate the recreational and religious value of the Reserve and its contribution to local livelihoods, (d) assess the extent of human-wildlife conflicts in the Reserve; and to (e) examine the attitude of local communities towards the conservation of the Reserve.

    A study people – Protected Area interface at Keibul Lamjao National Park, Manipur.
    (Wildlife Institute of India, Dehradun, 2014) Leima, Sanggai; Badola, Ruchi; Hussain, S.A.
    Keibul Lamjao National Park (KLNP) is the only natural home of the remnant population of endangered brow antlered deer or Sangai whose habitat is the phumdi- a unique part of the habitat of KLNP. It is a floating mass of entangled vegetation formed by the accumulation of organic debris and biomass with soil particles. It covers approximately two thirds of the area of the park and the thickness varies from a few centimeters to about two meters. However, due to illegal exploitation of resources from the park in the form of vegetable and fuelwood collection, the park is facing consistent anthropogenic pressures which are posing a threat to the habitat of Sangai. A need arises to understand local people’s dependence on the park as well as their perceptions and attitudes in order to devise management strategies to solve parkpeople conflicts. Thus, the main objectives of the present study were to (a) examine the socioeconomic and demographic conditions of the villagers around KLNP, (b) quantify the resources extracted from the park and its contribution to the livelihoods of the local people, (c) assess the impacts of anthropogenic activities on the wildlife habitat, (d) examine the conservation awareness and attitudes of people towards the park and alternative livelihood options and (e) to assess the economic value of the park in terms of recreation for the conservation of Sangai and KLNP.

    Role of provisioning and cultural ecosystem services of Protected Area in supporting human health
    (Wildlife Institute of India, Dehradun, 2024) Shekhar, Shashank; Badola, Ruchi
    Ecosystem Services (ES) are vital ecological functions that contribute significantly to human well-being. This study explores the provisioning and cultural ecosystem services provided by Kaziranga National Park (KNP), a UNESCO World Heritage Site in Assam, India, and their role in supporting the health and well-being of local communities. Despite extensive research on the general benefits of natural environments, specific studies on protected areas and their direct health benefits are sparse. This research addresses this gap by assessing how KNP's ecosystem services influence human health and well-being. The study aims to evaluate the multifaceted benefits of KNP, focusing on provisioning services such as fish, wild fruits, vegetables, and medicinal plants, as well as cultural services including recreation, aesthetic value, and traditional cultural practices. Methodologically, the research employs household surveys, interviews, economic valuation techniques, and ethnographic studies to gather comprehensive data on resource usage, cultural significance, and health outcomes. Data collection spans from 2018 to 2022, involving 750 households from 31 villages within KNP's zone of influence, along with a tourist survey of 379 individuals who visited KNP. Key findings reveal that local communities heavily depend on resources from the vicinity of KNP, with significant economic and health benefits. Provisioning services such as fish and wild vegetables contribute substantially to food security and traditional healthcare, while cultural services enhance mental health and community cohesion. The study establishes a positive correlation between the use of these ecosystem services and improved health metrics, such as reduced disease incidence and better overall quality of life. Additionally, cultural engagement within the park correlates with higher household income and educational access. The research underscores the critical role of natural ecosystems in supporting human health and advocates for integrated conservation and health policies. Sustainable management practices, community engagement, and technological advancements are recommended to preserve KNP's biodiversity and enhance its benefits. Future research should expand to include supporting and regulating services and assess the long-term impacts of climate change on KNP's ecosystem services. In conclusion, this study highlights the significant socio-economic and health benefits derived from KNP's ecosystem services, emphasizing the need for policies that integrate environmental conservation with public health and community development.
