    Identification of human-leopard hotspot the prioritizing the mitigation measures in Junnar Forest Division, Pune, Maharashtra
    (Wildlife Institute of India, Dehradun, 2020) Habib, B.; Khandekar, V.; Nigam, P.; Mondol, S.; Jayaramegowda, R.; Ghanekar, R.; Kumar, A.
    Mitigation of human-carnivore conflict became a priority to wildlife managers for the conservation of large carnivores and human livelihood. Hence, for the effective mitigation measure, it is necessary to identify the priority human-carnivore conflict hotspots. In India, the growing human population, infrastructure development, and land modification are affecting the large carnivore population leading to human carnivore conflict. Among human-carnivore conflict, human-leopard conflict is common in different geographical regions due to the adaptability of species across a different environmental gradient in India. Human-leopard conflict records of 20 years (1999-2018) were collected from the different ranges of the Junnar Forest Department (JFD) in the Pune district. The area is known for the human-leopard conflict for the past three decades. The records show an abrupt surge of human-leopard conflict after the year 2014. Using these records, spatio-temporal clusters of the hot spots and cold spots were identified using optimized hotspot analysis tool in ArcGIS. Also, five different categories of hot spots in the study area namely, new hot spots, consecutive hot spots and sporadic hot spots of human-leopard conflict through emerging hot spot analysis in ArcGIS were identified. It is suggested that different management approaches and strategies focusing on the different categories of hotspots are required to deal with human-leopard conflict for effective mitigation measures. Villages have been highlighted as the new conflict hotspots i.e. which has emerged in recent years. Immediate actions like intensive night patrolling and awareness in the villages to control will help in reducing human leopard conflict.

    Capacity building initiative on the dispersal and ranging patterns of elephants for effective management of human-elephant interactions
    (Wildlife Institute of India, Dehradun, 2022) Nigam, P.; Pandav, B.; Mondol, S.; Lakshmiarayanan, N.; Kumar, A.; Nandwanshi, V.B.; Das, J.; Biswas, S.; Udhayaraj, A.D.; Vishwakarma, R.; Habib, B.; Miachieo, K.; Narasingh Rao, P.V.
    Wild Asian elephant (Elephas maximus) populations are distributed in four major regions namely North West, North-East, East-Central and Southern regional meta-populations across India. Amongst them, the East-central regional population spread across the States of Odisha, Jharkhand, southern West Bengal, Chhattisgarh, and lately in Madhya Pradesh suffers disproportionately high levels of human elephant conflict. Among the myriad challenges facing management of human-elephant conflict in the region, elephant range expansion into new areas is overriding. One such range expansion that resulted in acute human-elephant conflict is being witnessed in the State of Chhattisgarh. Although northern Chhattisgarh was historically an elephant range, elephants reportedly disappeared during the period 1920 to late 1980s. While episodes of sporadic elephant occurrence in Chhattisgarh was reported during the period 1988- 1993, contemporary range expansion and concomitant human-elephant conflict began from the year 2000, and has accelerated during the last one decade. Faced with an enormous challenge of managing human-elephant conflict that is spatiotemporally dynamic unlike that of other elephant range States, constrained by limited Institutional capacities to assess and deal with the issue. Chhattisgarh Forest Department has been trying diversity its conflict mitigation strategies. Recognizing the need to objectively evaluate human-elephant conflict situation in the State, during the year 2017 Chhattisgarh Forest Department invited Wildlife Institute of India to conduct ecological research on elephants in Chhattisgarh with a three-year budget outlay. The project was a collaborative effort between Chhattisgarh Forest Department and WII. Considering the scope of the project, the project duration was further extended and eventually, the project lasted for the period July 2017 to March 2022. Being the final project report, the activities carried out as part of the project is summarized as under. Distribution and Demography In Chhattisgarh, the elephant distribution during the period 2012 to 2017 was reported from 16 Forest Divisions and four Protected Areas in the north and north-central regions of the state. The elephant population, as enumerated by Chhattisgarh Forest Department during 2021 , ranged from 250 to 300. The adult sex ratio recorded during the study was 1: 4.5. About 44% of the female segment of the population comprised of adults. Chhattisgarh elephant population is presently contiguous with other elephant populations in the neighboring states i.e., Madhya Pradesh, Jharkhand and in Odisha occurring as a meta-population 1 and thus cannot be considered as an isolated population. However, within Chhattisgarh, the population is relatively small and it occurs scattered over a large area as small and disjunctive groups facing a perpetual risk of getting isolated by ongoing linear infrastructure and other associated developmental activities in the State. If such groups get isolated, then they will not be viable in the long run. 1 Meta-population: Population of small populations that are connected through dispersals 1 O. ~ . -~ 1 -WU.d.U.fe .In.s-titu-te. o.f .In.di a Home Range, Movement Patterns & Dispersal, and Habitat Selection by Elephants During the period 2018-2022, WII-CGFD collaborative effort resulted in 10 elephant radio collaring in Chhattisgarh. The resultant effort provided 3106 elephant days of tracking information. Each of the radiocollared elephants provided an average of 310.6 (± 273) days of tracking data. As on 31 51 March 2022 when WII-CGFD collaborative project ended, two of the collared elephants (SD - Sehradev and MT - Maitri) were having functional collars. The estimated average home range (95% minimum convex polygon) of elephants in Chhattisgarh was 3172.8 km2 (± 2002.2 km2, Range: 462.3 - 6969.7 km2). The 95% kernel density home ranges of elephants were much lower averaging 512.3 km2 (± 235.3 km2, Range: 126.5 - 748.9 km2). The elephant home ranges were not wholly well defined, and marked by inter-annual shifts caused by exploratory behaviour. The elephant home ranges were relatively large. The dry season home ranges were significantly lower than monsoon and winter ranges. However, dry season home ranges of elephants are larger. The present study indicates that habitat quality in some of the forest patches - particularly those that are large and contiguous with minimal of human interference can potentially support elephants in the landscape. Thus, dry season ranges of elephants could serve as a surrogate for habitat quality. Monthly variations in home ranges were significant, and best explained by idiosyncrasies of individual elephants. Among the forest types open, moderately dense and very dense forests classified by Forest Survey of India based on crown densities, elephants selected open forests, that were predominantly juxtaposed with human-use areas. Although the crown density was low, the patches of open forests support dense stands of Sal (Shorea robusta) coppice with rank undergrowth offering adequate cover for elephants. Elephant habitat selection of these open forest patches appears to be influenced by potential foraging opportunities in human-use areas, and further facilitated by low inter-patch distance. Genetic Structure of Elephants Using 258 genetic samples collected from 9 Forest Divisions, elephant genetic structure in northern Chhattisgarh was evaluated. Analysis indicates that at least two different elephant lineages occur in Chhattisgarh. This implies that elephants occurring in Chhattisgarh have possibly come from different areas. Within the two different lineages, high relatedness amongst the individuals was observed corroborating with the general social structure of Asian elephant clans where individuals are mostly related. Crop Losses and Human Fatalities due to Elephants Crop losses caused by elephants were acute and widespread in Chhattisgarh. To draw an analogy, Karnataka's ex gratia payment towards crop losses by elephants during the period 2015-2020 was comparable with Chhattisgarh, although the former's elephant population is 93% more than the latter. The landscape-level assessment covering the whole of northern Chhattisgarh, and fine-scale assessment covering select areas in Surguja circle identified correlates of crop losses at both spatial scales. Elephant-related human deaths were widespread in the state. However, nearly 70% of incidences occurred in areas of high intensity of habitat-use by elephants. The human fatalities due to elephants were both temporally and spatially auto-correlated. 2

    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.

    Status of threatened medicianl and aromatic plants and their use by the Bhotiya community in Niti valley, Nanda Devi Biosphere Reserve, Uttarakhand
    (Wildlife Institute of India, Dehradun, 2022) Kumar, A.; Adhikari, B.S.; Mishra, A.P.
    Nested in the Western Himalaya, the state of Uttarakhand, also known as the ‘herbal state of India,’ harbors more than 5000 species of vascular plants, of which one-third species have medicinal uses. The state abounds in a rich and varied flora and fauna, constituting the most species-rich part of the whole of the Western Himalaya. The extreme north of the state contributes approximately 1% (ca. >1,000 km2) of the total Trans- Himalayan region (ca. 98,660 km2) of India. however, in spite of rich floral diversity, the cold-arid regions of Nilang, Niti, Mana, Johar, Darma and Byans valleys of Uttarakhand along the northern frontiers that falls under Trans-Himalayan Biogeographic Province (1C) are underexplored in terms of the current levels of pressure and patterns of biodiversity. These areas have also been facing tremendous pressure due to over-exploitation of forest resources including the unscientific and illegal harvesting of MAPs from the wild. The current study was conducted to study selected threatened and high use value MAPs in Niti valley, a cold-arid region of Nanda Devi Biosphere Reserve with a focus to (i) assess the status, abundance, and use of MAPs, and (ii) suggest their sustainable harvesting and cultivation framework. The information on the focal species was gathered through primary viz., semi-structured open-ended and closed-ended questions including individual interactions and group discussions in selected villages (7) and secondary information through offline and online sources. After reconnaissance and stratification of habitats, population status of focal species was assessed using stratified random sampling. Based on extensive interactions with younger generation, elder people including local healers, plant collectors and local traders, a total of five high value (with significant economic end usage) MAPs namely Allium tracheyi, Carum carvi, Dactylorhiza hatagirea, Picrorhiza kurroa and Sinopodophyllum hexandrum were selected in Niti valley, NDBR. The selection of MAPs was based mainly on highest quantum of collection and high threat due to removal and usages.The current study highlights that the population of the focal species (except Carum carvi) are sparse albeit rapidly declining due to excessive exploitation, unscientific, illegal and premature harvesting. Therefore, keeping their current population status in view, preparation of microplans, assessment of available growing stock and sustainable management and utilization of dwindling populations is recommended. Besides over-exploitation of MAPs, knowledge on their available stock,lack of information on end users and middlemen and inadequate information on quantity of raw material traded due to secretive nature of the markets were reported. In Niti valley, the market trend, price vis a vis trade route is indiscernible for highly traded medicinal species such as Gucchi, Morchella esculenta and Keedajadi, Ophiocordyceps sinensis which sells in the market like a hot cake, and therefore has created hue and cry state among the locals. Hence, these issues need to be addressed to ensure long-term conservation of the MAPs in a way that livelihood needs of the locals depending on such resources are not compromised. The focal species are one of the highly traded MAPs from the Western Himalaya, in general and Niti valley, particularly. Therefore, considering the existing threats, habitat specificity, population size and pressure level, the focus of conservation and regulated harvest is particularly needed for(i) restricted distribution heavy pressure (RDHP) species such as Picrorhiza kurroa and Dactylorhiza hatagirea, and (ii) locally common heavy pressure (LCHP) species such as Allium stracheyi, Sinopodophyllum hexandrum and Carum carvi in Niti valley, NDBR. Bhotiyas, ethnic community of Indo-Mongoloid origin mailny depend on natural resources from the adjacent forests and alpine pastures or meadows (locally known as payar) for their livelihood. Therefore, considering the high use value, market opportunities, price of the produce, and ease of cultivation or harvesting processes, the current study proposes Allium stracheyi, Carum carvi and Saussurea costus as the potential species that can be encouraged for their cultivation in Niti valley. It will not only provide livelihood opportunites to the local inhabitants butalso check ruthless exploitation of the wild MAPs. The local inhabitants are dependent on the wild MAPs for their traditional health care system. They are knowledgeable of about 72 MAPs that are locally utilized consumption and for curing at least 24 different human ailments. However, the practice of utilising MAPs in their local healthcare system is sharply declining due to lack of education facility and market, which has led to lack of knowledge as well as transfer of knowledge to younger generations. The payar such as Bamplas, Lang, Goting, Rekhana (base of Mount Kamet) and Geldung in Ganesh Ganga; Timersain and Thali enroute Kalajowar, and Daman towards Sagar glacier in Amrit Ganga are rich in medicinal plant diversity. Thus, considering the unique medicinal diversity and traditional ways of their conservation in view, rotation grazing in the forested areas including heavily grazed payars such as Daman, Thali, Timsersain and Goting in a cycle of 2-3 years is proposed. Owing to excessive human population, it is evident that the demand visa- vis harvesting pressure on wild populations of several MAPs is increasing every year. Thus, in order to meet the accelerating demand of high use value MAPs, there is an urgent need to develop farm scale agrotechniques for priority MAP species in the absence of such efforts on lab to land tested techniques. In the current study, sustainable harvesting and cultivation framework have been designed for the selected 05 MAPs,although appropriate demonstration sites showcasing such agrotechniques in the cold-arid landscapes such as Niti valley in Uttarakhand be set up to build confidence of the plant growers or locals in adoption of such medicinal crops in their agricultural practices.
