Item Open Access A Comprehensive Assessment of Red Wolf Reintroduction Sites(2018-04-24) O'Neal, ShaneThe red wolf (Canis rufus) is the world’s rarest wild canid, with fewer than 60 wolves living in the wild, and likely even fewer than 40. After being declared extinct in the wild in 1980, the wolf was reintroduced to Alligator River National Wildlife Refuge in North Carolina in 1987 and successfully established itself, with the small initial population growing to 150 within two decades. Recent increases in mortality have reduced the wolf’s numbers to their current low levels, and the Fish and Wildlife Service now faces the difficult decision of where else to reintroduce the red wolf within its historic range. This Masters Project is an attempt to analyze the current landscape of the Southeast from both an ecological and sociological perspective to determine the best possible places for red wolves to successfully establish a new population. I first conducted a literature review to identify key variables that affect the suitability of an area and found five such factors: available habitat, available prey, concentrations of livestock, recreational hunters, and the age of local residents. The reintroduction effort has to begin on federally owned and protected land, and so I next set out to select a suite of potential sites for the reintroduction to take place, establishing a list of 21 such locations. The relationship between all of the variables I considered is complex, so to properly weight them against each other I surveyed 14 experts in red wolf biology and management. I received responses from 10 of the experts and used this information to construct models in ArcGIS to determine the overall suitability of a site. After assembling a Weighted Sum model based on available data and calculating descriptive statistics, the sites all received a suitability score. The highest-scoring sites were Croatan National Forest in North Carolina and Okefenokee National Wildlife Refuge in Georgia. Fish and Wildlife should focus future reintroduction efforts on these locations, which strike the best available balance between suitable ecology and low chances of human-wolf conflict.Item Open Access A National Strategy to Increase the Efficacy of Timber Enforcement at U.S. Borders(2020-04-24) Aziz, NaimahSince 1900, the United States has relied on the Lacey Act to protect wildlife from unsustainable and illegal exploitation via the enforcement of tribal, state, and foreign laws. In 2008, Congress amended the Lacey Act to offer the same protection of plants including timber and wood products. Albeit, over a decade since enactment, on the ground enforcement of the Lacey Act Amendments is still in the early stages. This capstone explores leadership in wildlife conservation and proposes a plan to optimizes the enforcement of the Lacey Act Amendment at U.S. ports of entry. The final project is a national strategy that increases collaboration between border inspection agencies to close enforcement gaps and creates a workflow plan for timber inspections in an effort to combat timber trafficking. Using the resources provided in the strategy, border law enforcement officers can more effectively identify and inspect high-risk shipments.Item Open Access ACE Basin National Wildlife Refuge Forest Inventory and Carbon Stock Analysis(2021-12-08) Murphy, Mary CarltonThe ACE Basin National Wildlife Refuge (NWR) is 11,815 acres of critical wildlife habitat in South Carolina’s Lowcountry region. The Refuge contains a mosaic of forest types, including upland pine and hardwood, bottomland hardwood, and cypress-tupelo swamps. Periodic forest inventories serve to update Refuge managers on current forest conditions and identify areas outside of desired forest conditions. Desired Forest Conditions (DFC) are defined forest composition and structure metrics representing critical wildlife habitat. Active forest management, including thinning and prescribed fire, is often used on NWRs to meet DFC metrics, and thereby promote and enhance wildlife habitat. This project consisted of a 10-week forest inventory field assessment of ACE Basin NWR to evaluate current forest conditions in relation to DFC metrics. A subsequent analysis quantified how potential forest management activities to achieve DFC metrics would affect carbon stocks. Project findings suggest that most Refuge forests are outside of desired conditions and require a suite of management activities to achieve optimal wildlife habitat. These activities, however, will reduce forest carbon stocks and this project suggests forest management practices that may address these tradeoffs.Item Open Access An Ecologically Focused Guide to Community Solar Siting and Development(2024-04-25) Bowlin, Isaac; Dye, Logan; Freedman, JacobThe rapid expansion of utility-scale solar energy (USSE) development presents a significant challenge to achieving renewable energy goals while minimizing impacts on land use and wildlife. Current USSE siting practices prioritize efficient and cost-effective development strategies that do not adequately consider ecological impacts. This problem necessitates the development of ecologically friendly siting and facility arrangement strategies that minimize the effects of solar development on ecosystems and wildlife while promoting sustainable land use practices. However, the best management practices needed to achieve these objectives are still quite ambiguous, with minimal research conducted to quantify wildlife impacts and provide clear guidelines for policy implementation. Distributed solar generation (DSG) presents an alternative development strategy, generating electricity close to demand centers using smaller, localized solar arrangements. Community solar, a specific form of DSG, exemplifies this decentralized approach by allowing multiple community members to collectively benefit from a shared solar installation, expanding access to clean energy while reducing land use impacts. In partnership with The Nature Conservancy and Highline Renewables, our research analyzes the known implications of USSE, the potential for DSG to improve habitat connectivity, and the state policies enabling innovative community solar siting practices. This report seeks to inform researchers, policymakers, and solar developers of policy frameworks and development practices that prioritize sustainable solar development. Chapter 1 conducts a literature review on the known ecological impacts of USSE development, informing ecologists about and encouraging solar developers to employ low-impact siting strategies. Chapter 2 performs a novel, standalone geospatial analysis demonstrating how various solar facility arrangements and siting locations impact bobcat (Lynx rufus) connectivity. This analysis can help developers make informed decisions regarding solar facility placement and reinforces the need for policy frameworks that enable DSG. Next, in Chapter 3, we review current and emerging state community solar markets and provide recommendations to policymakers for designing future policies. Finally, in Chapter 4, we examine the role of agrivoltaics, the integration of solar generation with agricultural activities, as a strategy for developers to reduce solar facility land use impacts. Our Chapter 1 literature review found that USSE facilities cause direct mortality to aquatic insects, birds, and bats while altering the movement and connectivity of ground-dwelling animals such as Pronghorn (Antilocapra americana) and Florida Panthers (Puma concolor). However, significant knowledge gaps exist in understanding these impacts—notably, the lack of Before-After-Control-Impact (BACI) studies and the limited geographic scope of research. Nearly 50% of the existing U.S. research has been conducted in the desert southwest, severely limiting the ability to extrapolate findings to the broader U.S. Wildlife-friendly fencing and vegetation management can help maintain suitable habitat; however, these solutions must be studied in other regions to assess their effectiveness. The geospatial analysis conducted in Chapter 2 reveals that both siting practices and spatial arrangement of solar facilities greatly impact species movement across a landscape. By analyzing how the predicted movement patterns of bobcats in southeast Ohio responded to both a USSE development in Dixon Run and the theoretical redistribution of Dixon Run’s generation capacity, we found that by redistributing capacity across the landscape, impacts on bobcat movement are reduced. However, a sensitivity analysis revealed that the locations of the distributed solar were in areas already deemed poor habitat for bobcats. That said, it is important to note that relocation of a USSE facility the size of Dixon Run to the areas considered poor bobcat habitat was practically impossible. Small, localized installations were the only way to build in these areas. Our policy analysis reveals significant variation among individual state community solar markets in the size of allowable projects, subscriber composition, and siting practices they encourage. Maryland and Ohio demonstrate different approaches to community solar policy, with Maryland emphasizing reducing barriers to low and moderate-income (LMI) participation, while Ohio promotes solar development on distressed sites and brownfields. Notably, state community solar markets often lack specific incentives that promote low-impact siting practices that minimize the solar facility’s impact on the local habitat. To improve future community solar legislation, policymakers should offer grants, tax credits, and other financial incentives that prioritize the preservation of existing topsoil and vegetation, site away from ecologically sensitive areas, and support innovative land use practices, including agrivoltaics. Implementing agrivoltaics offers a promising solution to reducing the siting impacts of USSE facilities and the competing land demands for agricultural production and solar development. The literature reviewed demonstrates that agrivoltaic systems can benefit agricultural productivity, land use efficiency, panel efficiency, and livestock and ecosystem health. Agrivoltaic systems offer the greatest benefits under specific conditions, specifically hot and dry climates, where the shading provided by panels mitigates the effects of excessive heat and water stress on crop productivity and livestock well being. However, the efficacy of agrivoltaic systems can vary and is contingent upon various factors such as shading distribution, crop sensitivity, and environmental conditions. Future research into agrivoltaics should focus on optimizing system design, evaluating financial performance, and fostering landowner engagement to ensure the successful implementation of this innovative approach to land use.Item Open Access Citizen-Based Sea Turtle Conservation Across the Developing-Developed World Divide(2011) Cornwell, Myriah LynneThis dissertation research explores participatory sea turtle conservation monitoring through a comparison of two case studies, one in North Carolina (NC), USA and the other in Baja California Sur (BCS), Mexico. Participatory approaches in conservation management can supplement state capacity as well as strengthen the involvement of citizens in environmental governance and knowledge production. Despite scholarship challenging the validity of the categories of developing and developed nations, this categorical assumptions derived from this binary world divide continue to inform conservation, and theoretical vocabularies for local roles in conservation management. In developed nations, participatory conservation management is framed through the broader administrative rationalism discourse, and is identified as volunteer conservation or citizen science. In developing nations, participatory conservation management is approached through the discourse of biodiversity and the threats human society poses to it, and is identified through community-based processes of conservation stewardship. The two case studies analyzed in this dissertation serve to interrogate the ways in which these distinct discourses influence outcomes, and consider what may be obscured or overlooked due to discursive constraints.
Conducting ethnographic research in each case study site, I participated in and observed sea turtle conservation activities and conducted in-depth interviews with relevant sea turtle conservation actors as well as collected documents pertaining to the conservation programs. Sea turtle conservation monitors in NC and BCS perform functionally similar conservation tasks, and I collected data using similar techniques in order to maximize comparability. I compare the case studies, not to generalize to a population, but instead to speak to theoretical propositions and inform existing theory on participatory conservation monitoring.
Although participatory monitoring in NC and BCS does not result in a democratization of science, there are beneficial outcomes to participants in both places. NC sea turtle monitors are enabled to take ownership of sea turtle stewardship, and BCS sea turtle monitors are enabled to promote conservation and cultural change using the authority of science. These outcomes challenge assumptions about state capacity and local engagements with science in participatory conservation, and the disparate approaches to local roles in conservation in each `world.' The overall findings suggest that a multitude of factors are involved in the production of conservation program frameworks and participant outcomes, and more deeply interrogating the taken for granted assumptions behind conservation designs and implementation can offer stronger understandings of what participatory conservation management can (and cannot) achieve.
Item Open Access Developing an alternative approach to wildlife management in the Duke Forest(2017-04-25) Kramer, Renee; PalmerDwore, Hannah; Satin, PeterWildlife management is not currently a major priority of the Duke Forest, but staff have expressed an interest in making it a more significant aspect in future forest management decisions. We here used a multi-criteria decision analysis framework to explore a variety of wildlife management and monitoring alternatives with the aim of providing Duke Forest staff an adaptive tool for making well-informed wildlife management decisions. We identified potential management strategies by looking at forest management plans in use by peer institutions and then conducting a meta-analysis to determine the effect each of the potential strategies had on taxa of interest to Forest staff. We also looked at the possibility of using a community-based monitoring approach to supplement limited Forest staff resources through the use of expert interviews and a formal review of the literature, and assessed the importance of multiple components in ensuring quality data monitoring. We used the results of both of these analyses to construct a decision framework Duke Forest can use to identify wildlife management and monitoring schemes.Item Open Access Effects of hunting and human disturbance on wildlife near villages in northeastern Gabon(2018-04-27) MacCarthy, JamesBushmeat from wild animals is the primary source of protein and income for many rural communities in northeastern Gabon, but mammals also provide valuable ecosystem services that may be jeopardized by unsustainable hunting practices and human disturbance. In this study, we deployed nearly 200 camera traps over two years to investigate whether hunting and other forms of human disturbance resulting from resource extraction activities, such as logging, alter mammal communities in tropical forests. The results of our study indicate that hunting and human disturbance reduces large mammal abundance close to roads and in more populated areas. In particular, chimpanzees and mandrills occurred far from roads, possibly reflecting more intense hunting of these species either for meat or in retaliation for crop raiding. Low relative abundances may be partially offset by in-migration from source populations in remote forests, but the further expansion of logging roads could disrupt this buffering mechanism. Although we did not find any significant effects for medium mammals as a group, Peter’s duikers and white-bellied duikers responded negatively to hunting intensity and were more numerous farther from villages and Makokou. By contrast, small mammals, such as rats and brush-tailed porcupines, responded positively to the density of logging roads, suggesting that low abundances of medium and large mammals release them from predation and competition for resourcesor that disturbed forest provides a more favorable habitat for small mammals than primary forest. Our results indicate that anthropogenic factors strongly influence the abundances and distributions of species in our study and forecast wildlife communities dominated by small mammals in human disturbed areas. To ensure a sustainable supply of animal protein for rural people, rural communities must actively manage their forests for wildlife. Wildlife management systems near villages should include a quota system that allows year-round hunting of small mammals, but limits hunting of large mammals to specific months, seasons, and areas. Government- or NGO-funded compensation for crop damage could ease the antipathy towards animals and conservation, and funding of community-led wildlife monitoring could raise awareness of the effects of hunting and the ecological and livelihood benefits of large mammals. Likewise, forestry operations should prohibit hunting in their concessions, and actively enforce regulations against hunting and use of logging roads.Item Open Access Evaluating the Efficacy of iNaturalist & BioBlitzes as Biological Inventory Tools for Landscape Management(2021-12-08) Perkins, TroiWell-informed landscape management decisions rely on accurate data of species presence which is often a resource-intensive and time-consuming effort to collect. Due to limited resources, Duke Forest Management Team has been searching for novel tools such as citizen science techniques to help gather plant and wildlife species data as a part of its holistic approach to forest management. Two potential citizen science tools, BioBlitzes and iNaturalist, have the potential to help Duke Forest quickly document species presence. This project looks at a case study to determine on average how many species iNaturalist users observed in a year and if the hosting of a BioBlitz event increased the number of species and richness observed. To evaluate these tools while under COVID-19 conditions, past BioBlitz and iNaturalist data were collected from select National Parks in 2016-2020 and used as a case study for Duke Forest. Four models were created using the number of species observed and the number of observers from the case study data. The models were then evaluated with data from City Nature Challenge: Triangle Area and to iNaturalist data collected in Duke Forest to determine the model’s effectiveness. Data trends including seasonality, number of observers, and number of species per phyla were reported alongside model outputs to Duke Forest. Results from this study concluded BioBlitzes and iNaturalist are effective biodiversity inventory tools for landscape management. Also included is a list of recommended actions for Duke Forest based on this project’s results.Item Open Access Identifying Focal Wildlife Conservation Areas on Private Lands in North Carolina(2008-04-24T19:14:16Z) Baker, NicholasThere are over 1,200 threatened or endangered animal species in the U.S, of which 36 are located in North Carolina. To address this problem of species imperilment, all 50 states developed State Wildlife Action Plans (SWAP). As requested by Congress, each SWAP is to identify priority conservation areas in which limited resources can be directed towards. The North Carolina WAP lacks priority conservation areas. This paper identifies focal wildlife conservation areas on private lands in Moore, Hoke, Richmond, and Scotland counties for the purpose of maintaining and protecting biodiversity and assisting the NC Wildlife Resources Commission in WAP implementation. A geographic information system (GIS) was used to conduct the analysis. Three principal datasets were used in identifying focal areas: 1) North Carolina Gap Analysis Project (NCGAP) wildlife distribution models, 2) North Carolina land cover from 2001, and 3) NCGAP protected land boundaries. The focal areas were ranked individually based on three metrics: betweenness, area, and distance to protected land. Betweenness is based on the Euclidean distance between pairs of patches. A habitat patch with high betweenness is significant ecologically, because it indicates how important a particular patch is in maintaining linkages among other patches. The area of a patch is important in assessing whether a species would be able to survive a large-scale natural disturbance. Also, larger patches generally support a greater number of species or individuals. Finally, conserving patches of land that are close to protected lands increases the likelihood that species associated with the patches will continue to persist (i.e., species are more able to disperse throughout the landscape). Thirty-three potential wildlife conservation sites were identified. This information can assist conservation planners when dealing with limited funding and personnel. The approach of my analysis can be applied more broadly in order to establish habitat conservation or connectivity at a regional scale.Item Open Access Mammal Diversity, Persistence, and Conservation in India(2008-12-03) Karanth, Krithi KBiodiversity conservation issues are complex and contentious. In this dissertation, I focus on Indian mammal conservation science, management, as well as policy issues that shape these factors. I am particularly interested in, where and which mammals are extinction prone, and what factors promote species persistence in human-dominated landscapes. I examine patterns of extinction, range contraction and current distribution of 25 species of large mammals in India in Chapters 2 and 3. I apply occupancy models to data from a sub-continental scale expert opinion survey. I model species occurrence in relation to ecological and social covariates based on a priori hypotheses about the determinants of mammalian distribution patterns.
I find that all 25 large mammal species are extinction prone. I find time affects extinction, and conservation initiatives of the last four decades have allowed some species to re-colonize some areas. I find protected wildlife reserves are critically important for persistence of species. Many species with much of their habitat outside existing protected areas will require new protected areas to persist. I find that human population density negatively influences survival probability for species, and human cultural tolerance positively affected persistence of species. Most large-bodied animals, habitat specialists, and rare species had higher extinction probabilities. I find that in addition to protected areas, land use, and human population densities, regionally rooted cultural and religious factors have allowed some species to survive. Conservation strategies must integrate all these factors to ensure the survival of India's large mammals in the future.
Conservation efforts to protect wildlife in human-dominated landscapes, often requires relocation of people. This policy has rarely been examined in detail. In Chapter 4, I focus on a reserve in India's Western Ghats of India to assess resettlement experiences of people during and after implementation of a relocation project.
Lastly, the success or failure of conservation policies and management interventions be they for protecting wildlife or addressing needs of local communities, depends substantially on the attitudes of conservation practitioners. In Chapter 5, I examine the attitudes, perspectives and opinions of Indian conservationists towards conservation issues and policies in India.
Item Open Access Managing for Wildlife Habitat and Connectivity in the Duke Forest: Case Studies of Bobcats and Three Salamander Species(2021-04-29) Sultzer, KendraWith the expansion of human development, wildlife habitat is becoming more isolated on the landscape. To maintain healthy wildlife populations, land must be protected for connectivity among habitat patches. This study focused on meeting both wildlife habitat and connectivity needs within Duke Forest, a large 7,000 acre forest in an otherwise mostly urban matrix. Four indicator species (marbled salamanders, spotted salamanders, four-toed salamanders, and bobcats), representing three major habitats within Duke Forest, were selected from a recent regional connectivity plan. A maximum entropy (Maxent) modeling approach was used to predict bobcat habitat in Durham, Orange, and Chatham counties. Overlaying this bobcat prediction and three salamander species Maxent-predicted habitat layers onto the connectivity data determined priority management areas. Recommendations were compiled from the literature to provide Duke Forest guidance on where and how to manage for the habitats of salamander species, which would be most sensitive to management activities. Suggestions included management specifications pertaining to timber harvest, prescribed fire, streamside management zones, and vernal pools or constructed wetlands. This work highlighted how a regional connectivity plan can be implemented at a local level and used for future management strategies.Item Open Access Modeling Salamander Habitat and Connectivity in Durham and Orange Counties, North Carolina(2019-04-18) Geschke, JuliaSalamander species in the Piedmont region of North Carolina are under-studied. This region is undergoing rapid expansion, urbanization, and human population growth, all of which will affect salamander habitat and salamanders directly, making it important to know where populations are currently located. This project assessed the usage of two methods, rule-based modeling and Maxent modeling, to predict habitat for eleven species of salamander found in Durham and Orange counties. These predicted habitat maps can be used to prioritize land conservation, areas for on-the-ground salamander surveys or management, and areas to avoid the use of certain forest management activities. The project also assessed the connectivity of ponds and wetlands used by pond-breeding salamanders. Corridors between ponds were identified for each Duke Forest division, and potential conflict areas with roads were highlighted. The results can be used to mitigate road mortality during breeding seasons, when large numbers of adults migrate, and after breeding seasons, when juveniles metamorphose and emigrate. Despite being one of the most urbanized parts of the state, the Triangle region of North Carolina is still home to a surprising diversity of salamander species. As the region grows, salamander habitat will dwindle, making it important to identify and conserve the best habitat and current salamander populations.Item Open Access Sahibs and Shikar: Colonial Hunting and Wildlife in British India, 1800-1935(2009) Shresth, SwatiThis dissertation explores the colonization of wildlife in nineteenth and early twentieth century British India. It discusses hunting and colonial policies on wildlife to explore the political, social and cultural concerns that influenced British interactions with Indian wildlife, with their compatriots and with natives. Hunting, I argue was deeply implicated in the exercise of power in all these interactions. British policies on wildlife in the nineteenth century favored a neat categorization of wild animals as "vermin and "game." By the beginning of the twentieth century however, with decreasing numbers of carnivores and native opposition, the perceived complementarily between game preservation and vermin extermination was shattered. While the colonial administration continued both these policies, they also actively sought to formulate policies to protect all animals in areas designated as sanctuaries and national parks. Colonial hunting as it emerged from the late nineteenth century reflects the changing nature of the colonial state and a new imperial ideology of dominance. I also argue racial differences between the colonialists and colonized were articulated in the domain of hunting. While hunting represented domination of nature and natives, the "colonial hunt" also came to signify a paternal benevolent British rule. The importance given to hunting and to the notion of fair play in their hunting served to "identify" the moral and physical superiority of British rulers. The new ideology of paternalism was realized in the figure of the hunter-officer, the Sahib who in hunting dangerous carnivores was seen to act as a protector of the native. The changing nature of the colonial state and creation of racial differences also had a profound impact on colonial society which became increasingly self conscious of its own identity and image. Given the metropolitan engagement with social Darwinism and their location on the fringes of civilization as it were, colonialists became the center of metropolitan preoccupation with racial contamination. The emphasis on fair play, I argue reflects the efforts of the colonial elite to enforce a model code of conduct on its members and reassure an anxious metropole of the racial distance with the native. Policing behavior of their own, through categories like fair play was therefore essential to the agenda of creating racial differences. Due to a perceived connection between hunting, power and privilege, hunting also played an important role in social relations in colonial society. As hunting came to be regulated by laws by late nineteenth century, it often became the focal point of tensions in class and power within the colonial elite on the question of access to animals.
Item Open Access The Effects of Hunting on a Forest Animal Community in Gabon(2015-04-24) Blanchard, EmilyGabon holds some of the world’s richest, most species-diverse tropical rainforest. Over 80% of the country’s landcover is forest and up to 20% of its plant and animal species are endemic. However, as the country seeks to increase its economic development through practices such as logging, the resulting creation of new roads and settlements in formerly remote areas increases the risk of bushmeat hunting and poaching. Species such as the African forest elephant have already experienced dramatic declines from hunting, which poses potential ecological consequences such as reduced seed dispersion. This study examined the effects of hunting on an animal community in a northeastern area of Gabon by measuring three types of hunting pressure: roads, waterways, and human populations. I focused on 9 animal species (Crowned Guenon, Grey-cheeked Mangabey, Mustached Monkey, White-nosed Guenon, Blue Duiker, Yellow-backed Duiker, African Forest Elephant, Chimpanzee and Gorilla) because of their specific targeting by bushmeat hunters or poachers and because they had adequate data to estimate population abundance. The study area, a 5,800 sq. km region in the Ogouué Ivindo province of northeastern Gabon, reflected a gradient of human activities and hunting pressure. The study consisted of direct (animals seen or heard) and indirect (dung piles or nests) observations along 24 transects, which were walked at least once per month from January to December 2014. I used these observations to calculate species abundances and compared these to past estimates. In addition, I analyzed abundance correlations with the three forms of hunting pressure. Overall, 8 of the 9 species analyzed in this study have declined in abundance since their previous estimates. Blue Duikers have suffered the most drastic decline, followed by Chimpanzees and White-nosed Guenons. Distances to the nearest small village and nearest main road were the overall strongest and most commonly significant indicators of hunting pressure. Results suggest that most of the study area’s species decline has been caused by excessive bushmeat hunting. On the whole, the entire wildlife community is declining in abundance and these trends are likely to continue unless measures are taken to reduce rates of hunting and poaching.Item Open Access The Effects of Land Use Change on Carnivore Use of Wildlife Dispersal Routes in Ranthambhore Tiger Reserve, India(2017-04-27) Ranganathan, PriyaAs the human population increases and climate change exacerbates resource scarcity, India’s wildlife faces the increasing threat of fragmentation and habitat loss in a human-centric landscape. The wild exists in small semi-isolated pockets, connected sparsely, if at all, by wildlife corridors. Such wildlife corridors may be the last hope for charismatic megafauna such as the Bengal tiger (Panthera tigris tigris). This project assesses the impacts of encroachment and land use change on the use of two wildlife dispersal (corridors) connecting Ranthambhore National Park (RNP) to other intact forest patches in the larger Ranthambhore Tiger Reserve (RTR) by the tiger and other large carnivores. The research objectives are: (1) to quantify land use and land cover change between 2011 and 2016 in RTR; (2) to assess the effects of this change on the two major wildlife dispersal corridors; and (3) to better understand how this affects land cover preference and use by tigers. Field data collection of wildlife presence and human encroachment in the two corridors was carried out during May-June 2016, and geospatial analysis was used to generate maps for WWF-India, as well as to study the changes in the landscape over the five-year period. Major threats to corridors were found to be the expansion of agricultural land, sand mining, overgrazing of forest vegetation by livestock, and urban expansion. Agricultural expansion has caused a decline in forest and ravine land cover, which are preferred by dispersing carnivores. Most threats were concentrated around the northwest corridor, making it a conservation priority. The southeast corridor is also heavily used by dispersing tigers as it is mostly characterized by ravines, a preferred habitat type; however, flattening of ravines for agricultural expansion and mining brings carnivores into proximity with humans, increasing the potential for conflict in the region. Based on these results, we recommend increased protection of the buffer zone of the northwest corridor and suggest that remaining efforts be put towards conservation education and stricter regulation of land use practices in areas surrounding corridors and intact habitat patches.
