    Ecology of leopard Panthera pardus in relation to prey abundance and land use pattern in Kashmir Valley
    (Wildlife Institute of India, Dehradun, 2014) Habib, Bilal; Gopi, G.V.; Noor, Athar; Mir, Zaffar Rais
    Globally, leopard (Panthera pardus) is the most widely distributed and persecuted cat amongst large cat species. In India, it largely coexists with other feline species like the tiger (Panthera tigris) across much of its distribution range and with lion (Panthera leo) and clouded leopard (Neofelis nebulosa) in certain areas of its distribution range. Owing to its very high adaptability for surviving in varieties of habitats and opportunistic feeding behavior, it is often found to be at the center of the human-wildlife conflict. Retaliatory persecution, poaching, habitat loss and declining natural prey are some of the factors which lead to its population decline, despite being accorded protection through national and international legislations. In Kashmir Himalayas it is at the top of the food chain and an apex predator that aids in regulating prey populations. However, there has been an increase in the human-leopard conflicts in the valley which, if left unnoticed, will worsen the conservation prospects of this threatened felid. Hence, this long term study was initiated to address two major issues: 1. Conservation and management planning of the leopards in the valley is impeded by the paucity of reliable empirical ecological information and 2. Current threat levels will have to be assessed to understand and predict the impacts of anthropogenic pressure on leopards. The objectives of the study were to estimate leopard population and prey abundance, to study the leopard feeding habits and to determine the ranging behavior of leopards. Dachigam National Park was selected to undertake ecological studies on leopards. Only the lower Dachigam was chosen as an intensive study area as the upper reaches of Dachigam are mostly high alpine areas where leopards do not inhabit. In order to study prey abundance, line transect methodology was adopted. Transects (n = 13) were laid and monitored in the study area to obtain seasonal prey abundance. In order to estimate smaller prey (rodents) abundance, Sherman traps (n = 49) were used to estimate density. Feeding habits of the leopards were studied by collecting leopard scats (n = 714) which were later analysed using standard protocols. The population of leopard in the study area was estimated using camera traps (n = 12 pairs), deployed in 2x2 km grids in the study area to individually identify leopards with their unique coat patterns. The ranging pattern of leopards was studied by tracking the leopards (n = 3) fitted with Vectronics GPS collars. Amongst large prey, Himalayan grey langur and Hangul were sighted with enough records to be amenable to analysis in program DISTANCE version 6.0. In total 170 groups of langur comprising of 2679 individuals and 206 groups of hangul comprising of 829 individuals were sighted across different seasons in the study area. Overall density (±SE) of langur was estimated to be 16.32 ± 1.87 km ² and of hangul 5.11 ± 0.51 km-² in the study area. Langur density was highest (22.05 ± 5.12/km²) in winter season and lowest (9.35 ± 3.03/km²) in summer season whereas, Hangul density was found to be highest (9.51 ± 1.71/km²) in spring season and lowest (2.31 ± 0.51/km²) in summer season. In case of rodents, the density was found to be highest during summer season (2014 ± 830.71/km²) and lowest during winter season (1172.6 ± 442.74/km²). In case of dietary spectrum of leopard in Dachigam, small rodents contributed the maximum (48.05%) in terms of percent frequency of occurrence followed by langur (14.04%). Hangul contributed 2.05% while Himalayan serow contributed only 0.20% and rhesus macaque contributed the least (0.10%) to the diet of leopard. Minimum sample size required to study food habits of leopard varied from 66 to 86 scat samples in different seasons. Jacobs' index calculated from biomass availability and biomass consumption indicates that small rodents and langur were preferred in all the four seasons. Preference of hangul was slightly higher (-0.79) during winter season as compared to summer season (-0.90). A total of 396 trap nights resulted in a total of 14 leopard photographs with 3 individual leopards. Amongst the three individuals, 2 males and 1 female was photo-captured. Although, the Null (M ) model 0 was selected based on highest criterion score, we selected the Heterogeneity (M ) model because h leopards are territorial animals and it accounts for heterogeneous capture pobabilities between individuals. The density estimate produced by average home range radius (HHR) was 2.11 ± 1.06 2 individuals per 100 km which was found best as density of the leopard in the study area. The relative abundance index of the leopard in the sampling duration turned out to be 3.5 per 100 trap nights. The maximum home range (100% MCP) of the 2 female F74 was ~ 74 km which was recorded during summer season. The summer home range (100% MCP) of the male was 1.96 times larger than the female leopard. The least home range (~ 41.4 2 km ; 100% MCP) came up during the winter season. The increasing trend represented by the ranges (100% MCPs) of this female was winter < spring 2 2 (48.42 km ) < autumn (67.9 km ) < summer. The leopards showed large variation in daily distances moved during the lean season of summer. Daily displacements of the leopards were not normally distributed Kolmogorov-Smirnov Test) for the male: M73 (D = 0.119, df = 105, p = 0.001), female: F71 (D = 0.191, df = 105, p = 0.000) and female: F74 (D = 0.092, df = 105, p = 0.029). Daily displacement was longer for the male leopard (median displacement = 588 m) than the female leopard (median displacement = 367.44 m). The total distance travelled by the male leopard (398.71 km) was greater than the female leopards: F74 (374.16 km) and F71 (62.91 km). In case of female leopard F74, the median daily distance travelled was highest during the winter season (0.664 km) followed by autumn (0.528 km), spring (0.506 km) and summer (0.367 km) Findings of this study indicate that leopards are facing prey scarcity in the area, thus making them to rely upon suboptimal prey and occupy home ranges larger than other studies in the subcontinent. Leopards being opportunistic feeders have also started feeding on domestic prey in absence of sufficient wild prey, thereby elevating the human - leopard conflict in the region. Human - animal conflict being the major threat to large carnivores all across their distribution range is a big impediment in leopard conservation in he study area as well. 1. Estimation of prey density across different sites and developing a relationship between density of prey base and leopard abundance. 2. Study variation of food habits across different sites and seasons in Kashmir valley. 3. Estimate density, abundance and distribution of leopard across different study sites. 4. Study movement pattern, home range size and social organization of leopards across different sites

    Establishment of knowledge management system for East Godavari River Estuarine Ecosystem (EGREE) Andhra Pradesh
    (Wildlife Institute of India, Dehradun, 2017) Sivakumar, K. ; Johnson, J.A.; Gopi, G.V.; Lal, Panna; Rajashekhar, P.V.; Bhadury, P.; Kumar, Ritesh; Rao, Tulsi K.; Kathula, Tarun; Malla, Giridhar; Ray, Paromita; Bagaria, Priyamvada; Anand, Dipak; Prasad, Leela
    Global warming has already affected the marine and coastal ecosystems at greater extent. According to the Intergovernmental Panel on Climate Change, sea levels in India are expected to rise at the rate of 2.4 mm a year; in 2050, the total increase will be 38 cm. 2. East Godavari River Estuarine Ecosystem (EGREE) encompassing the Godavari mangroves is the second largest area of mangroves along the east coast of India. The area is rich in floral and faunal diversity, and generates significant ecological and economic benefits such as shoreline protection, sustaining livelihoods and carbon sink services. 3. It is situated at the confluence of Godavari River with Bay of Bengal in the East Godavari district of Andhra Pradesh. The geographical scope of this study lies between 16°59'23" N, 82°18'16" E and 16°34'57" N, 82°18'38" E. 4. EGREE encompasses the vast delta of Godavari River along with other coastal habitats such as mangroves, river channel, floodplains, natural levees, bay, mudflats, tidal creeks, sand spits, beaches etc. 5. Presence of a 17 km-long spit, called Hope Island provides natural shelter to the coast and city of Kakinada. It has allowed the establishment of a major fishing harbor and the Kakinada Port, thereby accruing high economic values to the region. 6. In recognition of its national and global biodiversity significance, the northern part is also protected as Coringa Wildlife Sanctuary (CWLS), which encompasses around 235.70 sq.km of mangrove forests. 7. The main production sectors currently operating in EGREE are fisheries, aquaculture, salt pans, tourism and manufacturing activities such as, oil and gas exploration, fertilizers, edible oil, rice products. Kakinada, a city located in EGREE is also one of the important ports of Andhra Pradesh and is being developed further into a ‘Smart City’. 8. These activities are impacting the overall ecological integrity of EGREE particularly the mangrove ecosystems, with associated impacts on the livelihoods of local communities. 9. The Ministry of Environment, Forests and Climate Change and the Government of Andhra Pradesh with support from UNDP and GEF initiated the project 'Mainstreaming Coastal and Marine Biodiversity into Production Sectors in the East Godavari River Estuarine Ecosystem, Andhra Pradesh'. 10. In order to advice and monitor the implementation of this GOI-UNDP-GEF Project in EGREE, a National Project Steering Committee (NPSC) was constituted under the chairmanship of Additional Director General of Forests (Wildlife), Ministry of Environment and Forests (now Ministry of Environment, Forests and Climate Change). The 1st meeting of the National Project Steering Committee (NPSC) of the project was held on 28th June 2011 in the Ministry of Environment, Forests and Climate Change, New Delhi. In the meeting, it was decided that Wildlife Institute of India (WII) would establish a Knowledge Management System envisioned under the project and co-ordinate all activities related therein. 11. Main goal of the project was to establish a Knowledge Management System (KMS) for East Godavari River Estuarine Ecosystem in Andhra Pradesh. It had four objectives viz. identifying research gaps, study the impacts of climate change, identify and assess the ecosystem services, and conducting a national workshop on mainstreaming biodiversity conservation into production sectors in EGREE.

    Manual for comprehensive environmental and socio-economic monitoring in Kailash Sacred landscape, India
    (Wildlife Institute of India, Dehradun, 2017) Rawat, G.S.; Gopi, G.V.
    Need for systematic documentation of rapidly vanishing bio-resources in the Himalayan region and long term monitoring of environmental parameters in the wake of changing climate has long been felt by the ecologists and natural resource managers. Long term ecological and socio-economic monitoring (LTESEM) was visualized as one of the major components of Kailash Sacred Landscape Conservation and Development Initiative (KSLCDI) since early stage of programme formulation. Accordingly, the International Centre for Integrated Mountain Development (ICIMOD), under its transboundary landscape programme, organized a series of expert consultations and workshops to finalize key parameters and protocols for monitoring. During the first phase of programme implementation (2013-’17), the Kailash partners tested these protocols in their respective countries. It was decided that the detailed methods used for monitoring various parameters would be compiled and disseminated among researchers, teachers and students desirous of initiating ecological observations and monitoring. Keeping this in view, we have brought out this manual covering various tools and techniques giving specific examples from Indian part of Kailash Sacred Landscape (KSL).

    A rapid field survey of tigers and prey in Dibang Valley district, Arunachal Pradesh
    (Wildlife Institute of India, Dehradun, 2014) Gopi, G.V.; Qureshi, Qamar; Jhala, Y.V.
    The Dibang valley district is the largest district of Arunachal Pradesh with an area of 9129 sq km and is also the least populated district of the country with approximately 1 person/sq km. The district shares international borders in the north, North West and Eastern sides with Tibet (China), the South Western region is bound by Upper Siang district and the Southern Side is bound by lower Dibang Valley district. This district was chosen to survey for tigers and their prey due to the recent rescue of tiger cubs from the district in Angrim valley during december 2012. Our survey confirms the occurrence of tigers in the district. We camera trapped the first ever image of an adult tiger from the Dibang valley Wildlife Sanctuary. We also observed 10 pubmarks and collected 11 scats in and around the WLS. All the 24 people whom we informally interviewed confirmed the presence of tigers in the WLS and reported either having had a direct sighting, observed indirect evidences or heard about livestock depredation incidents by the tigers. Preliminary assessment of prey suggest that the WLS holds a good diversity and abundance of prey like Takin Budorcis taxicolor taxicolor, wild pig Sus crofa, Goral Naemorhaedus goral, Musk deer Moschus fuscus, Barking deer Muntiacus muntjak, Himalayan Serow Capricornis thar and Mithun Bos frontalis which can sustain a good population of tigers in the DWLS. The DWLS has the potential of becoming a tiger reserve in future as it may harbour a very important source population of tigers in this region, However the next immediate priority must be to ensure that this vital tiger population is protected and continuously monitored. This can be achieved by a collaborative effort between NTCA, WII, GoAP and most importantly the local people by conducting long term research to establish robust ecological and genetic baselines that can aid in long term conservation and monitoring of tigers, co-predators, prey and their habitats in this unique landscape that in part of a global biodiversity hotspot.

    Status of wildlife between Kota barrage and Jawahar Sagar Dam, Rajasthan
    (Wildlife Institute of India, Dehradun, 2021) Johnson, J.A.; George, Arun; Sharma, Megha; Kavin, D.; Sreelekha Suresh; Gopi, G.V.; Hussain, S.A.
    The present study examined the impacts of post-construction phase of the cable-stayed bridge on the aquatic wildlife and river habitat quality of the Chambal River between Kota barrage and Jawahar Sagar dam, Rajasthan. The study was carried out between March and November 2021. The study area was divided into 5 segments (each comprising 5 Km length of river) and the segment 1 stats from the Kota barrage. We recorded good signs/ activities of smooth-coated otters in the study area. This species is listed under “Schedule II” of IWPA 1972 and "Vulnerable" as per the IUCN Red List. A total of 10 sites within five river segments were surveyed for otter signs during pre-monsoon and post-monsoon seasons. Out of which five sites (50%) have shown positive otter signs (fresh spraints, tracks, and direct sightings) during pre-monsoon, whereas in the post-monsoon season the number of otters occupied sites have reduced to four sites (40%). The otter occupancy map indicated, the segment 2 (just above the bridge area) had high level of otter presence. We recorded good population of bird diversity between Kota barrage and Jawahar sagar dam. A total of 132 bird species, which includes 45 wetland birds (N=1569), 21 species of raptors (N=928), and 66 species of other terrestrial birds (N=1351) were recorded. These include two Critically Endangered (Indian Vulture and Red-headed Vulture), one Endangered (Egyptian Vulture), one Vulnerable (Woolly-necked Stork) and four Near Threatened species (River Tern, Black-headed Ibis, Oriental Darter and Alexandrian parakeet). During the study period, the raptors, Indian Vulture (Gyps indicus) and Egyptian vultures (Neophron percnopterus) were very commonly recorded and more number of nests were recorded in the third segment of the study stretch. In addition to vulture nests, we also observed nests of Bonelli's eagle (Aquila fasciata) and Dusky eagle-owl (Bubo coromandus) in the riverside escarpments. We also recorded nests of three waterbird species, which include Grey Heron (Ardea cinerea), Black-crowned night heron (Nycticorax nycticorax) and Woolly necked stork (Ciconia episcopus). Avian richness was varying with the season maximum number of waterbirds were observed during pre-monsoon (S=40), this same trend was followed by raptors (S=15) and other terrestrial birds (S=57). The bird occupancy map indicated that the segment 1 and segment 2 supported high abundance birds. We also recorded two species of aquatic reptiles, which are Mugger (Crocodylus palustris) and Indian roofed turtle (Pangshura tecta). Though, the river banks are mostly of rocky and large boulders with limited sand beach, we found quite a few nesting sites of muggers along the river banks. A total of 34 individuals and 23 individuals of muggers were recorded during pre-monsoon and post-monsoon respectively. The study area also supports good population of freshwater fishes. Rapid Assessment Report - 6 - During the study we recorded 46 species of fishes from the study area. Fishes belonging to the carp family were dominant in species richness (S=22). Among the 46 species of fish, three species are listed under threatened categories as per the IUCN Red List. During the study period the important physicochemical parameters of the water was monitored and the values were significantly varied between the river segments (p<0.05). The pH was found to be slightly alkaline across the river segments ranged from 7.08±0.02 and 8.55±0.01. Like conductivity, total dissolved solids in water (TDS) varied, ranging from 91.54 ppm at the second segment of the river in postmonsoon to 150 ppm at the second segment in pre-monsoon. All water quality parameters were found within the normal range of river water quality. Based on our findings we conclude that the cable-stayed hanging bridge of Kota does not have any negative impact on the wildlife of the Chambal River. The bridge is on the stable rocky gorge area, around 30 m above the water level across the river Chambal without any supporting billers from the riverbed. Thus, there is no direct contact between the river and bridge structure. Further, the technology used in this structure is marvellous, because it is totally vibration and notice proof. In this study we had some significant observations very close to this cable bridge such as an active nest of Egyptian Vulture (Neophron percnopterus) very close to this bridge (25° 8'23.14"N, 75°47'36.64"E), which is just 80 meters away from the bridge and a nest of Woolly-necked Stork (Ciconia episcopus) just 200 meters downstream from the bridge (25° 8'20.90"N, 75°47'33.11"E). Generally, Woolly-necked Storks are assumed to prefer isolated areas for nesting (Mehta 2020). Previous studies indicated that disturbance is one of the major factors for avoiding nesting habitat by Storks (Bouton et al., 2005). We also observed the permanent roosting sites of the Indian eagle-owl (Bubo bengalensis) nearer to this bridge (25° 8'16.12"N, 75°47'27.02"E). Likewise, we observed number of direct sighting of otters and crocodiles near as well as downstream regions of bridge when compared to other segments of the rivers. Moreover, the water quality parameters examined were within the normal range of river water quality. Thus, the present study revealed that the presence of cable-stayed bridge does not have any negative impact on the aquatic wildlife and quality of habitats in the Chambal River.

    Review of site-specific wildlife management plan(January 2021) of North Koel Reservoir Project (Mandal Dam)
    (Wildlife Institute of India, Dehradun, 2021) Jha, R.R.S.; Gopi, G.V.
    This review consists of three parts. In the first part, largely through secondary sources, we provide a background of the North Koel Reservoir Project and information on Palamau Tiger Reserve (PTR) where the project is situated. We mention how the task of reviewing the Site-specific Wildlife Management Plan (January 2021) in lieu of diversion of 1007.29 hectares area (ha) of forest land for the project came to the Wildlife Institute of India (WII). We also describe our review objectives, methodology and approach towards the task, as well as limitations, as communicated to the Department of Forest, Environment & Climate Change, Government of Jharkhand. In the second part, we first provide general comments and observations on the plan and thereafter chapter-wise analyse and evaluate the same, with respect to our objectives and based on relevant guidelines framed and circulated by the office of the Principal Chief Conservator of Forests (Wildlife) and Chief Wildlife Warden (CWLW), Government of Jharkhand in this regard in 2015. We provide detailed observations and suggestions towards strengthening each chapter. We then mention details of our field visit including our learnings and insights gained from interactions with different stakeholders. In the third and concluding part, we provide recommendations towards improving the plan to benefit inhabiting wildlife and ecosystems in and around the project site and in its impact zone, as well as PTR as a whole. The second and third parts, thus, contain primary inputs in the form of actionable comments and suggestions from WII. We recommend a multi-seasonal year-long biodiversity assessment in the project impact zone. We also suggest exercising caution and applying scientific rationale in the use of barriers to reduce negative human-wildlife interactions and/ or to limit illegal activities. We also recommend setting aside budget towards empowering ecodevelopment committees in various management and conservation activities; upgrading facilities, providing training, equipment and field gear, and welfare for frontline staff (both temporary and permanent); and a comprehensive research program for PTR. We recommend drawing up detailed plans for ecotourism in PTR, providing alternative livelihood opportunities for the local indigenous population, habitat creation and habitat management towards wild herbivores’ population augmentation etc to enable further scrutiny of such plans, among other suggested interventions. Relevant appendices are provided towards the end

    Implementing artificial canopy bridges to connect fragmented population of Hoolock gibbon in Hollongapar Gibbon Sanctuary, Assam
    (Wildlife Institute of India, Dehradun, 2023) Jha, R.R.S; Zangmo, S.; Gopi, G.V.
    Habitat loss and habitat fragmentation are two principal threats to most terrestrial biodiversity across ecosystems and geographies. Gibbons are a particularly vulnerable group of primates inhabiting the forests of South and Southeast Asia. Of the 20 gibbon species – all threatened, according to the International Union for Conservation of Nature or IUCN – the endangered Western Hoolock gibbon Hoolock hoolock is the only one found in India inhabiting the forests in the southern bank of the Brahmaputra-Dibang river system. The Hollongapar Gibbon Sanctuary (HGS) is a small ~21 sq.km Protected Area (PA) in Jorhat, Assam and is one of the species’ stronghold supporting around 125 individuals living in more than two dozen family groups. It is also the only PA in India named after a primate species. Apart from the W. Hoolock gibbon, the Sanctuary also harbours six other primate species – capped langur Trachypithecus pileatus, stump-tailed macaque Macaca arctoides, northern pig-tailed macaque M. leonina, Assamese macaque M. assamensis, rhesus macaque M. mulatta, and Bengal slow loris Nycticebus bengalensis, thereby having the distinction of harbouring the highest primate species diversity for any Indian PA. However, a single track ~1.65 route-km long railway line (currently broad-gauge, but un-electrified as yet) has fragmented the Sanctuary since 1887 into two unequal parts. Over time, the Sanctuary has become a ‘forest island’ having lost connectivity with surrounding forest patches. Since gibbons are exclusively arboreal animals inhabiting the forest upper canopy, they are particularly sensitive to canopy gaps. Gibbon families on both sides of the railway track have, thus, been effectively isolated from each other, thereby compromising their population genetic variability and further endangering their already threatened survival in the HGS. Worldwide, and even in India, several conservation initiatives have attempted bridging such canopy gaps in forests through artificial canopy bridge (ACB) structures to facilitate arboreal species’ movements. The Wildlife Institute of India, Dehradun was approached by the Divisional Forest Officer, Jorhat (Territorial) Division of the Assam State Forest Department (ASFD) to provide specific design inputs towards the installation of such canopy bridges at the HGS. In this context, this report provides design guidelines and considerations as well as specific location-wise details of seven (07) potential sites within HGS for such canopy bridges installation, following thorough literature survey, field data collection and interaction with stakeholders such as ASFD officials and field staff, railway officials and consultants, and local conservationists. We recognise and emphasise that the design, successful installation and post-installation monitoring of canopy bridges require the involvement of several individuals with professional expertise in fields such as forestry, ecology/primatology, engineering and mountaineering/climbing. Post-installation monitoring of the canopy bridge structures – both behavioural observations of animals around canopy gaps and installed structures as well as through arboreal camera traps to assess bridges’ use – is one of the most important aspect of this project. As is clear, the present un-electrified single-track ~1.65 route-km railway line passing through the HGS has caused distress and posed significant conservation issues to arboreal animals. Hence, a future doubling of the line (if planned) will increase the canopy gap to a large extent and render any conservation interventions (such as ACB installations) futile. Over the longer period of time, it will be best if the status quo is maintained, although electrification of the existing single track may be permitted subject to necessary statutory approvals with appropriate mitigation and compensation measures implemented after detailed investigation of its ecological impacts. Forest regeneration on both sides of the existing track through afforestation activities to gradually enable natural canopy connectivity, adherence of trains to speed limits when passing through HGS and its Eco-Sensitive Zone/wildlife corridors, ensuring landscape connectivity of the isolated ‘forest island’ HGS with neighbouring patches of forests, and rerouting of the existing railway line outside Sanctuary limits, and establishing and supporting low-impact home-stay based ecotourism facilities are some of the longer-term interventions necessary to ensure that W. Hoolock gibbons and other canopy-dwelling species persist and thrive within HGS and in the immediate larger landscape.

    Site inspection report on the ecological impacts of Jamrani Multipurpose Project of Uttarakhand Irrigation Department, Nainital district, Uttarakhand
    (Wildlife Institute of India, Dehradun, 2023) Gopi, G.V.; Arya, S.K.; Yadav, A.; Zangmo, S.; Saini, S.; Laha, D.R.; Banerjee, K.
    The WII team visited the field site and collected primary field data, had meetings with the stakeholders and collated the necessary secondary information pertaining to this project. The proposed project falls within the Dudwa-Lagga Tiger Corridor, which is an important corridor for tigers in the Terai Arc Landscape. As this report is to facilitate and guide informed decision making by the NTCA, we present two decision making scenarios with differing objectives: (i) Keeping the Dudwa-Lagga Tiger Corridor intact and conserving this as utmost importance or (ii) Balancing the interests of both development and conservation values. Should the objective (i) be chosen, then the proposal has to be rejected, and if the objective (ii) is chosen then stringent compliance conditions has to be stipulated and an independent multidisciplinary committee comprising of members from NTCA, WII, FRI/ICFRE, State FD may be constituted to oversee the implementation of mitigation measures on a half yearly basis and submit their report to NTCA for strict compliance by the project proponent. This will facilitate a regular, transparent and stringent monitoring of compliance by the project proponent.
