Snow leopards and sustainability : livelihoods, governance and coexistence in the Nepal Himalayas

Hanson, Jonathan H. January 2018 (has links)
This thesis seeks to understand the coexistence that occurs between people and snow leopards on the roof of the world. Within a political ecology framework, it aims to show how various social and economic factors can influence this coexistence and promote the conservation of Himalayan species and ecosystems. In particular, the thesis addresses the twin assumptions that access to assets, via more diverse livelihoods, and access to influence, via decentralised conservation governance, will improve coexistence. The study opens with an assessment of household livelihoods and then compares them between two iconic but contrasting Protected Areas. The thesis then assesses: (i) knowledge of and attitudes to snow leopards; (ii) attitudes to their conservation; (iii) household livestock losses to snow leopards; and (iv) conflicts between people and snow leopard conservation. Additionally, perceptions of several proposed mitigation methods are also examined. The political ecology framework employs access theory, the Sustainable Livelihoods model and a mixed-methods approach. Using systematic sampling, a quantitative questionnaire was administered to 705 households at two sites in the Nepal Himalayas: Sagarmatha National Park, with a centralised governance model, and Annapurna Conservation Area, with a decentralised one. Seventy qualitative interviews were also collected for cross-methods triangulation. Multiple and logistic regression models were the main form of statistical analyses. Access to tourism income, and larger household size, best explained livelihoods scores. Attitudes to snow leopards were best explained by attitudes to their conservation and numbers of livestock owned per household. Attitudes to snow leopard conservation depended on perceptions of snow leopards and household livelihoods. Perceptions of conflict with snow leopards and their conservation was related to the number of livestock lost by any source of mortality. A number of variables explained attitudes to the proposed mitigation measures, including gender, livelihood strategies, livestock numbers and support for snow leopard conservation. In conclusion, access to assets and access to influence do shape human coexistence with snow leopards and their conservation, albeit in more nuanced ways than anticipated.

Ecology and conservation of leopards, Panthera pardus, on selected game ranches in the Waterberg region, Limpopo, South Africa

Swanepoel, Lourens Hendrik 30 November 2009 (has links)
Leopards (Panthera pardus) currently inhabit large parts outside formal conservation areas in South Africa. While leopards are not currently threatened in South Africa, regional populations are at risk. Conflict between leopards and ranchers is common in livestock and game ranching areas, often resulting in persecution. Negative attitudes towards leopards, caused by anti-predator sentiments and leopards preying on livestock and game are normally the reason for leopard persecution. The lack of data available for leopards on game ranches hampers current conservation efforts. A questionnaire survey was used to investigate the attitudes of ranchers towards leopards. Overall ranchers were positive towards leopards and negative attitudes towards leopards were attributed to their predation on livestock and game. Reported game and livestock losses were low, suggesting that local rumours play an equally important role in negative attitudes towards leopards. A Global Positioning System connected to cell phone transmitters [GPS/GMS] were fitted to leopards to determine home ranges and movement. GPS/GSM collars performed satisfactory with only 18 % of data missing. Leopards used smaller home ranges than expected. Social organisation was characterised by a mosaic of overlapping female ranges, while one male home range overlapped several female home ranges. Greater distances were travelled during the night than daytime. Home ranges of leopards covered a great number of ranches, while core areas were restricted to only a few ranches. Investigation of GPS clusters were used to determine age, sex and weight of prey killed by leopards. Data from kills were used in combination with scats to construct leopard diets. Leopards preyed on a variety of mammals, the most important being kudu (Tragelaphus strepiceros), bushbuck (Tragelaphus scriptus) and warthog (Phacochoerus aethiopicus). Suggestions for the management of leopards are discussed. / Dissertation (MSc)--University of Pretoria, 2009. / Animal and Wildlife Sciences / unrestricted

Viability of leopards Panthera pardus (Linnaeus, 1758) in South Africa

Swanepoel, Lourens Hendrik January 2013 (has links)
Leopards Panthera pardus are highly adaptable large felids that persist in un-protected areas throughout South Africa. However, leopards are frequently involved in conflict with land users and subsequently killed in retaliatory incidents. Efforts to foster tolerance for leopard conservation largely rely on trophy hunting and ecotourism. However there is growing concern that trophy hunting may lead to population declines. Combining this with shortages of demographic data generates serious conservation challenges for wildlife managers. In this thesis, I evaluated the viability of the South African leopard population using simulation models and empirically collected data. I further evaluated the response of people engaged in retaliatory killing of leopards and leopard trophy hunters to varying leopard abundance. A habitat suitability model suggested that current suitable leopard habitat is fragmented and that the majority exists on non-protected areas. The national protected area system was largely ineffective in capturing suitable leopard habitat. Stochastic population models suggested unsustainable harvest levels at the current levels of retaliatory killing. Furthermore, simulations with only non-harvest related anthropogenic mortality also produced high probabilities of decline, indicating that non-harvest related anthropogenic mortality, such as retaliatory killings, can significantly impact the sustainability of harvest and the viability of the South African leopard population. Likewise survival analysis indicated that leopard survival in non-protected areas was significantly lower than in protected areas, and that humans were responsible for the majority of leopard deaths in non-protected areas. Finally retaliatory killing occurred at a higher rate of killing at low leopard abundances compared to hunting. Therefore retaliatory killing of leopards are more likely to be detrimental to leopard populations than trophy hunting. My findings strongly suggest that non-protected areas are important for leopard conservation, but that conflict in these areas currently may limit their conservation potential. I therefore suggest that the control of retaliatory killing of leopards may be more effective in promoting leopard persistence than restricting trophy harvest. Furthermore, conservation actions that aim to foster increased participation by the private sector, representing non-protected areas, in large carnivore conservation initiatives may be particularly beneficial to the long term conservation of leopards. / Thesis (PhD)--University of Pretoria, 2013. / gm2013 / Animal and Wildlife Sciences / restricted

The ecology of the leopard (Panthera Pardus) in the Waterberg

Grimbeek, Anton Michael 17 November 2005 (has links)
Although the opportunistic feeding habits of leopards were evident in this study, scat analysis showed that ungulates were by far the predominant food, with impala being the most frequent item. The fact that cattle calves were only taken up to ± 100 days old, emphasize the relevance of a proper stock management program to prevent stock losses. In addition, where such measures were impractical, temporary physical barriers such as electric fencing showed potential for application. Modification on different capture techniques were investigated not only to capture leopards for radio collaring but also for the elimination of problem leopards. The effective home range size of a resident male and female leopard in the Naboomspruit area were calculated at 303 km2 and 157 km2 respectively. A density of one leopard per 53 km2 are suggested for the Naboosmpruit study area. Both leopards were predominantly nocturnal with some crepuscular activity. Translocation experiments revealed different results. The conducting of translocations in farming areas, where problem leopards are involved are however not suggested. Leopard density and distribution patterns showed that numbers are relative safe, and that populations are currently to a large extent linked, which makes natural gene flow a possibility. Although suitable areas for leopards thus exist, these may not be available as homogenous units in the future, due to increasing human pressure. / Dissertation (MSc (Zoology))--University of Pretoria, 2006. / Zoology and Entomology / unrestricted

Personality and well-being in felids : assessment and applications to captive management and conservation

Gartner, Marieke Cassia January 2014 (has links)
Research in animal personality has been increasing over the last decade, as scientists realise its importance to a variety of health outcomes. In particular, personality has been shown to have an effect on immune function, stress, infant survival, overall well-being, morbidity, and mortality. Because of this, personality can play an important role in captive management, especially as stress is often a problem for captive animals. Research has already shown that personality affects captive breeding efforts, enclosure grouping, and stress regulation in some species. Only a few studies have focused on felids, but these have shown that there are possible applications for personality in that taxon. Because most felids are endangered, and because many of them face special challenges in captivity due to their size and biology, this work aimed to increase knowledge on felids, using personality as a framework, with implications for captive management as a target. Focusing on five species, I assessed the personality of domestic cats, Scottish wildcats, clouded and snow leopards, and African lions, and the well-being of the four latter species. With the exception of the domestic cat, there has been little to no personality work in these species, and none on well-being. I then compared the data within and among these species. I found three main personality factors among the species, including dimensions I labelled Neuroticism, Dominance, and Impulsiveness, with some differences, including an Agreeableness factor in some species, and elements of Openness. As in other species, well-being was negatively related to Neuroticism in most of the study species. Taking into consideration each species’ biology, natural history, and genetics, I discuss the implications and importance of using these species’ personality and well-being assessments in both captive management and conservation efforts. The results indicate that, like in humans, a targeted, individual approach to care is the best use of personality for captive animals.

Tracking collar and infrastructure for leopard research

Warnich, Dirk J. 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: This project targeted the development of a new tracking collar, trap telemetry system and supporting infrastructure, to aid researchers from the Cape Leopard Trust. Previously used collar products had all proven insu cient in some capacity and remote monitoring of trap sites was also required. Tracking collars are used to identify the movement patterns of the leopards and through the resulting research, assist in protecting this threatened species. In the development of the tracking collar and trap telemetry system, a high level system design was rst formulated, identifying major components that would be required. Alternative methods for implementation were then considered and the most optimal chosen. Two di erent modes of communication with the collar were envisioned and designed for. These would be used to transmit logged coordinates obtained from a GPS receiver back to researchers. A VHF terrestrial radio link was investigated, but an Iridium Satellite based solution was ultimately selected. An Iridium Satellite communications system was also used for transfer of trap state data. Ultimately, a working trap telemetry system was delivered for use by researchers. The tracking collar system had progressed to a working prototype, requiring miniaturisation and packaging before deployment. A possible packaging solution was also identi ed. The trap telemetry system, although displaying certain de ciencies, provided a capability previously unavailable to researchers. With further development, there is potential for the tracking collar to provide accurate satellite tracking and communications in a mass and price combination not previously available. / AFRIKAANSE OPSOMMING: Hierdie projek het as doel die ontwikkeling van 'n nuwe opsporingshalsband, 'n lokval telemetriese stelsel en die nodige ondersteunende infrastruktuur daarvoor. As hulpmiddels vir navorsers van Cape Leopard Trust. Geen van die halsband produkte wat tot nou toe gebruik is, het voldoen aan al die nodige behoeftes nie, en dit was ook nodig om die lokvalterreine van 'n afstand te kan monitor. Die opsporingshalsbande word gebruik om die bewegingspatrone van luiperds vas te stel en die navorsing wat daarop volg, help dat 'n bedreigde spesie bewaar word. Die ontwikkeling van die opsporingshalsband en lokval telemetriese stelsel het begin met die formulering van 'n ho evlak stelselontwerp waarin die hoofkomponente wat benodig sou wees ge denti seer is. Alternatiewe metodes van bewerkstelling is daarna oorweeg en die optimale hiervan is gekies. Twee verskillende metodes van kommunikasie met die halsband is voorgestel en ontwerp. Hierdie sou gebruik word om die vasgelegte koordinate wat van 'n GPS ontvanger verkry is, na navorsers terug te versend. 'n Terrestriale radioverbinding is ondersoek, maar 'n Iridium Satelliet-baseerde oplossing is uiteindelik verkies. 'n Iridium Satelliet kommunikasie stelsel is ook gebruik vir die oordrag van data aangaande die lokvaltoestand. Uitendelik is 'n werkende lokval telemetriese stelsel gelewer vir dir gebruik van navorsers. Die opsporingshalsband stelsel was nou 'n werkende prototipe, wat slegs verklein en toepaslik verpak moes word voor dit in gebruik geneem kon word. 'n Moontlike oplossing tot die verpakkingsprobleem is ook identi seer. Die lokval telemetriese stelsel, hoewel dit steeds tekorte toon, voorsien die navorsers van voorheen onbekombare inligting. Met verder ontwikkeling is daar potensiaal vir die opsporingshalsband om akkurate satellietopsporing en kommunikasie te voorsien in 'n kombinasie van laer massa, sowel as prys, soos nog nooit voorheen beskikbaar nie.
