Title Spatial density pattern of Himalayan Ibex (Capra sibirica) in Pakistan Type Journal Article
Year 2022 Publication Global Ecology & Conservation Abbreviated Journal
Volume 39 Issue e02288 Pages 1-12
Keywords (down) Himalayan ibex, Population, Hindu Kush, Himalaya, Karakoram, Pakistan
Abstract Mountain ungulates perform a key role in maintaining the balance of ecosystems as they are the primary consumers of vegetation and prey for large predators. The mountain ranges of northern Pakistan are home to six species of mountain ungulates, and the Himalayan ibex (Capra sibirica), hereafter ibex, is the most abundant among them. This study was conducted in three administrative regions of northern Pakistan, viz. Gilgit-Baltistan (GB), Azad Jammu and Kashmir (AJK), and Khyber Pakhtunkhwa (KP), to generate a range-wide density pattern map of ibex. A double-observer survey was conducted in 25 study sites during 2018–2021 across the ibex distribution range, covering an area of about 35,307 km2, by walking transects totaling 1647 km. Within the ibex range where the survey was not conducted due to financial and logistical constraints, we obtained species population information from local wildlife departments’ most recent annual survey data. The aim was to generate a density map for the entire ibex range. Using the BBRe-capture package in program R, we estimated an ibex population of 7639 (95 % CI) with a mean density of 0.21/km2 in the surveyed area. Combining with the secondary data from un-surveyed areas, the total population estimate for the country came to 10,242 ibex. The largest population densities were observed in four valleys (Shimshal, Gulkin-Hussaini, Khyber, and Khunjerab) of the Karakoram-Pamir range, followed by the Hindu Kush range (Chitral Wildlife Division [WD]). The central and eastern parts of the Karakoram range had moderate to low densities, while the Himalayan range (e.g., Astore Valley) supported a small population. The mean herd size was 15 individuals (range: 5–41), and the average detection probability of observers A and B was 0.69 and 0.48, respectively. The average male and young ratios per 100 females were estimated to be 75 and 81, respectively. The range-wide density map developed during the study provided an evidence for the impact of trophy hunting programs and an objective tool for range-wide conservation planning of the species.

Title Assurance of the existence of a trans-boundary population of the snow leopard (Panthera uncia) at Tsagaanshuvuut – Tsagan- Shibetu SPA at the Mongolia-Russia border Type Journal Article
Year 2020 Publication Integrative Zoology Abbreviated Journal
Volume Issue 15 Pages 224-231
Keywords (down) FST, home range, Panthera uncia, snow leopard, trans-boundary population
Abstract The existence of a trans-boundary population of the snow leopard (Panthera uncia) that inhabits the massifs of Tsagaanshuvuut (Mongolia) – Tsagan-Shibetu (Russia) was determined through non-invasive genetic analysis of scat samples and by studying the structure of territory use by a collared female individual. The genetic analysis included species identification of samples through sequencing of a fragment of the cytochrome b gene and individual identification using a panel of 8 microsatellites. The home range of a female snow leopard marked with a satellite Global Positioning System (GPS) collar was represented by the minimum convex polygon method (MCP) 100, the MCP 95 method and the fixed kernel 95 method. The results revealed insignificant genetic differentiation between snow leopards that inhabit both massifs (minimal fixation index [FST]), and the data testify to the unity of the cross-border group. Moreover, 5 common individuals were identified from Mongolian and Russian territories. This finding clearly shows that their home range includes territories of both countries. In addition, regular movement of a collared snow leopard in Mongolia and Russia confirmed the existence of a cross-border snow leopard group. These data support that trans-boundary conservation is important for snow leopards in both countries. We conclude that it is crucial for Russia to study the northern range of snow leopards in Asia.

Title Leopards in African Rainforests: Survey and Monitoring Techniques Type Miscellaneous
Year 2003 Publication Abbreviated Journal
Volume Issue Pages
Keywords (down) forest leopards; african rainforests; survey; monitoring techniques; lope reserve; gabon; central africa; congo; zaire; field testing; populations; wild meat; relative abundance; density; live-trapping; presence and absense surveys; ad-hoc survey; bushmeat; systematic survey; monitoring; individual identification; tracks; Discriminant Function Analysis; genotyping; scat; Hair; Dna; remote photography; camera trapping; capture rates; Trailmaster; Camtrakker; bait; duikers; pigs; elephant; bongo; okapi; human hunters; 5300
Abstract Monitoring Techniques Forest leopards have never been systematically surveyed in African forests, in spite of their potentially vital ecological role as the sole large mammalian predators in these systems. Because leopards are rarely seen in this habitat, and are difficult to survey using the most common techniques for assessing relative abundances of forest mammals, baseline knowledge of leopard ecology and responses to human disturbance in African forests remain largely unknown. This technical handbook sums up the experience gained during a two-year study of leopards by Philipp Henschel in the Lop‚ Reserve in Gabon, Central Africa, in 2001/2002, supplemented by additional experience from carnivore studies conducted by Justina Ray in southwestern Central African Republic and eastern Congo (Zaire) . The main focus of this effort has been to develop a protocol that can be used by fieldworkers across west and central Africa to estimate leopard densities in various forest types. In developing this manual, Henschel tested several indirect methods to assess leopard numbers in both logged and unlogged forests, with the main effort devoted to testing remote photography survey methods developed for tigers by Karanth (e.g., Karanth 1995, Karanth & Nichols 1998; 2000; 2002), and modifying them for the specific conditions characterizing African forest environments. This handbook summarizes the results of the field testing, and provides recommendations for techniques to assess leopard presence/absence, relative abundance, and densities in African forest sites. We briefly review the suitability of various methods for different study objectives and go into particular detail on remote photography survey methodology, adapting previously developed methods and sampling considerations specifically to the African forest environment. Finally, we briefly discuss how camera trapping may be used as a tool to survey other forest mammals. Developing a survey protocol for African leopards is a necessary first step towards a regional assessment and priority setting exercise targeted at forest leopards, similar to those carried out on large carnivores in Asian and South American forests.

Abstract Snow leopard preservation efforts by Russian biologist Eugene Koshkarev are hampered by the lack of technology and the attitudes of the local population. Without access to radio-collars until recently, the biologists have had to use low-tech research methods such as field observation. The chabani, or semi-nomadic herders of Central Asia, fear the leopards as predators and set traps. Local governments also allow hunting

Title Edge effects and the extinction of populations inside protected areas Type Journal Article
Year 1998 Publication Science Washington D.C. Abbreviated Journal
Volume 280 Issue 5372 Pages 2126-2128
Keywords (down) edge-effects; extinction; human-animal-conflict; mortality; population-size; protected-areas; browse; edge effects; Human; Animal; conflict; population; protected; area; 590
Abstract Theory predicts that small populations may be driven to extinction by random fluctuations in demography and loss of genetic diversity through drift. However, population size is a poor predictor of extinction in large carnivores inhabiting protected areas. Conflict with people on reserve borders is the major cause of mortality in such populations, so that border areas represent population sinks. The species most likely to disappear from small reserves are those that range widely-and are therefore most exposed to threats on reserve borders-irrespective of population size. Conservation efforts that combat only stochastic processes are therefore unlikely to avert extinction.

Title A downlist is not a demotion: Red List status and reality Type Journal Article
Year 2017 Publication Oryx Abbreviated Journal
Volume Issue Pages 1-5
Keywords (down) Cryptic, IUCN Red List, Panthera uncia, population estimate, snow leopard, species assessment
Abstract Assessments of biodiversity status are needed to

track trends, and the IUCN Red List has become the accepted

global standard for documenting the extinction

risk of species. Obtaining robust data on population size is

an essential component of any assessment of a species� status,

including assessments for the IUCN Red List. Obtaining

such estimates is complicated by methodological and

logistical issues, which are more pronounced in the case of

cryptic species, such as the snow leopard Panthera uncia.

Estimates of the total population size of this species have,

to date, been based on little more than guesstimates, but a

comprehensive summary of recent field research indicates

that the conservation status of the snow leopard may be

less dire than previously thought. A revised categorization,

from Endangered to Vulnerable, on the IUCN Red List was

proposed but met some opposition, as did a recent, similar

recategorization of the giant panda Ailuropoda melanoleuca.

Possible factors motivating such attitudes are discussed.

Downlisting on the IUCN Red List indicates that the species

concerned is further from extinction, and is always to be

welcomed, whether resulting from successful conservation

intervention or improved knowledge of status and trends.

Celebrating success is important to reinforce the message

that conservation works, and to incentivize donors.

Title Understanding population baselines: status of mountain ungulate populations in the Central Tien Shan Mountains, Kyrgyzstan Type Journal Article
Year 2020 Publication Mammalia Abbreviated Journal
Volume Issue Pages 1-8
Keywords (down) conservation; human-use landscapes; hunting concession; mountain ungulates; population baselines; protected areas.
Abstract We assessed the density of argali (Ovis ammon) and ibex

(Capra sibirica) in Sarychat-Ertash Nature Reserve and its neighbouring

Koiluu valley. Sarychat is a protected area, while Koiluu is a human-use

landscape which is a partly licenced hunting concession for mountain

ungulates and has several livestock herders and their permanent

residential structures. Population monitoring of mountain ungulates can

help in setting measurable conservation targets such as appropriate

trophy hunting quotas and to assess habitat suitability for predators

like snow leopards (Panthera uncia). We employed the double-observer

method to survey 573 km2 of mountain ungulate habitat inside Sarychat

and 407 km2 inside Koiluu. The estimated densities of ibex and argali in

Sarychat were 2.26 (95% CI 1.47–3.52) individuals km-2 and 1.54 (95% CI

1.01–2.20) individuals km-2, respectively. Total ungulate density in

Sarychat was 3.80 (95% CI 2.47–5.72) individuals km-2. We did not record

argali in Koiluu, whereas the density of ibex was 0.75 (95% CI

0.50–1.27) individuals km-2. While strictly protected areas can achieve

high densities of mountain ungulates, multi-use areas can harbour

meaningful

though suppressed populations. Conservation of mountain ungulates and

their predators can be enhanced by maintaining Sarychat-like “pristine”

areas interspersed within a matrix of multi-use areas like Koiluu.

Title Spatial variation in population-density, movement and detectability of snow leopards in 2 a multiple use landscape in Spiti Valley, Trans-Himalaya Type Journal Article
Year 2020 Publication bioRxiv Abbreviated Journal
Volume Issue Pages
Keywords (down) Co-existence; land sharing; population-density; spatial capture recapture; Pseudois nayaur Capra sibirica; ungulates; livestock.
Abstract The endangered snow leopard Panthera uncia occurs in human use landscapes in the mountains of South and Central Asia. Conservationists generally agree that snow leopards must be conserved through a land-sharing approach, rather than land-sparing in the form of strictly protected areas. Effective conservation through land-sharing requires a good understanding of how snow leopards respond to human use of the landscape. Snow leopard density is expected to show spatial variation within a landscape because of variation in the intensity of human use and the quality of habitat. However, snow leopards have been difficult to enumerate and monitor. Variation in the density of snow leopards remains undocumented, and the impact of human use on their populations is poorly understood. We examined spatial variation in snow leopard density in Spiti Valley, an important snow leopard landscape in India, via spatially explicit capture recapture analysis of camera trap data. We camera trapped an area encompassing a minimum convex polygon of 953 km . We estimated an overall density of 0.49 (95% CI: 0.39-0.73) adult snow leopards per 100 km . Using AIC, our best model showed the density of snow leopards to depend on wild prey density, movement about activity centres to depend on altitude, and the expected number of encounters at the activity centre to depend on topography. Models that also used livestock biomass as a density covariate ranked second, but the effect of livestock was weak. Our results highlight the importance of maintaining high density pockets of wild prey populations in multiple use landscapes to enhance snow leopard conservation.
