Abstract: When densities of large carnivores fall below certain thresholds, dramatic ecological effects
can follow, leading to oversimplified ecosystems. Understanding the population status of
such species remains a major challenge as they occur in low densities and their ranges are
wide. This paper describes the use of non-invasive data collection techniques combined
with recent spatial capture-recapture methods to estimate the density of snow leopards
Panthera uncia. It also investigates the influence of environmental and human activity indicators
on their spatial distribution. A total of 60 camera traps were systematically set up during
a three-month period over a 480 km2 study area in Qilianshan National Nature Reserve,
Gansu Province, China. We recorded 76 separate snow leopard captures over 2,906 trapdays,
representing an average capture success of 2.62 captures/100 trap-days. We identified
a total number of 20 unique individuals from photographs and estimated snow leopard
density at 3.31 (SE = 1.01) individuals per 100 km2. Results of our simulation exercise indicate
that our estimates from the Spatial Capture Recapture models were not optimal to
respect to bias and precision (RMSEs for density parameters less or equal to 0.87). Our
results underline the critical challenge in achieving sufficient sample sizes of snow leopard
captures and recaptures. Possible performance improvements are discussed, principally by
optimising effective camera capture and photographic data quality.

Abstract: An increasing proportion of the world�s poor is rearing livestock today, and the global livestock population is growing. Livestock predation by large carnivores and their retaliatory
killing is becoming an economic and conservation concern. A common recommendation for carnivore conservation and for reducing predation on livestock is to increase wild prey populations based on the assumption that the carnivores will consume this alternative food. Livestock predation, however, could either reduce or intensify with increases in wild prey depending on prey choice and trends in carnivore abundance. We show that the extent of livestock predation by the endangered snow leopard Panthera uncia
intensifies with increases in the density of wild ungulate prey, and subsequently stabilizes. We found that snow leopard density, estimated at seven sites, was a positive linear function of the density of wild ungulates�the preferred prey�and showed no discernible relationship with livestock density. We also found that modelled livestock predation increased with livestock density. Our results suggest that snow leopard conservation would benefit from an increase in wild ungulates, but that would intensify the problem of livestock predation for pastoralists. The potential benefits of increased wild prey abundance in reducing livestock predation
can be overwhelmed by a resultant increase in snow leopard populations. Snow leopard conservation efforts aimed atfacilitating increases in wild prey must be accompanied by greater assistance for better livestock
protection and offsetting the economic damage caused by carnivores.

Abstract: The snow leopard Uncia uncia is a globally endangered species, occurring in China and 11
neighboring countries, with a total population of 3500-7000 individuals. China is very important
for Snow Leopards, as it contains both the more than half of the distribution area and the largest
remaining population. However, like other big cats, the density is very low, perhaps less than 1
individual per 100 square kilometers in the western mountains of China. This book first reviewed
ten years of research by Xinjiang Snow Leopard Team (XSLT), and it contains over 300 figures
including maps, illustrations, pictures and photos, 46 tables as well as more than a thousand
references and 1100 key words in the index.
In the past ten years, XSLT has received much support and funding from the Snow Leopard
Trust (SLT) and the Xinjiang Conservation Fund (XCF). In this regard, the Chinese government
has not yet given one cent to support the Xinjiang Snow Leopard Project. Our situation is very
difficult indeed, and it is hoped that this book will inspire future government support.
There are many topics discussed in this work including a decade of successes or failures with
the Snow Leopard Survival Strategy (SLSS from 2002 to 2012). The authors also present findings
from every International Snow Leopard Conference (1978-2008), the stories of 14 experts, the big
events of conservation and research (1776-2012), and many questions for future research in the
appendix. This is the first work about snow leopards in China. It is a popular scientific book that
covers snow leopard monitoring, research, conservation and management, and it could also be
very helpful to nature reserve staff and scientists as well as students, teachers, outdoor explorers,
volunteers and cat lovers.
The book contains the following: preface, table of contents (in English), and chapters on the
ancient records of snow leopards; their place in the family of big cats; research methods and field
logs for snow leopards; their population size and distribution in China; biological knowledge,
conservation and management of snow leopards; their presence in zoos; Nature Reserves in
Xinjiang, the experiences of snow leopard conservation in other countries; appendix; index; and
afterword (ISBN 978-7-03-036723-5, the book was published in March 2013 with total of 616
pages and approximately 0.77 million Chinese words, price: RMB 145.00 Yuan).
