Human-wildlife Conflict in the Chang Tang Region of Tibet: The Impact of Tibetan Brown Bears and other Wildlife on Nomadic Herders with Recommendations for Conflict Mitigation. Lhasa, Tibet Autonomous Region, China: WWF China-Lhasa Field Office, 2006.
The multiple-use Chang Tang and Seling Lake Nature Reserves were created in 1993 to protect the unique assemblage of large fauna inhabiting the high-altitude steppe grasslands of northern Tibet, including the Tibetan antelope, Tibetan wild ass, Tibetan brown bear, Tibetan Gazelle, wild yak, and snow leopard. Prior to creation of the reserve, many of these species were heavily hunted for meat and sale of parts. Since creation of the reserve, however, killing of wildlife by subsistence hunters and commercial poachers has declined while in the past five years a new problem has emerged, that of human-wildlife conflict. With human, livestock, and wildlife populations in the reserves all increasing, and animals apparently emboldened by reserve-wide hunting bans, all forms of human-wildlife conflict have surged rapidly since 2001. This conflict takes on four primary forms in the Chang Tang region: 1)killing of domestic livestock in corrals and on open pastures by Tibetan brown bears, snow leopards, and other predators, 2) Tibetan brown bears badly damaging herders’ cabins and tents in search of food, 3) loss of important grass resources to large herds of widely migrating wild ungulates, particularly the Tibetan wild ass, possibly leading to winter starvation of livestock, 4) driving off of domestic female yaks by wild yak bulls in search of harems.
In April of 2006, the authors conducted a wildlife conflict survey of 300 herding households in Nagchu Prefecture’s Shenzha, Tsonyi, and Nyima Counties. Results showed that the 87 percent of households had experienced some form of wildlife conflict since 1990. The Tibetan brown bear was the largest source of wildlife conflict, affecting 49 percent of surveyed households, followed by grazing competition conflict which affected 36 percent of surveyed households, and snow leopard conflict which affected 24 percent of surveyed households. Type and frequency of wildlife conflict problems cut across all three surveyed socio-economic factors, residence type, size of living group, and economic status/herd size, and was primarily a function of location. A break down of incidences of human-wildlife conflict into three 5 to 6-year time periods between January 1990 and April 2006 revealed dramatic increases in conflict occurring since 2001. When compared to the 1990-1995 period, the incidence of conflict today ranged from 2.6 times higher for fox conflict to 5.5 times higher for conflict with snow leopards, while there was a 4.6 fold increase in the occurrence of bear conflict. From second-hand accounts and wildlife remains confiscated from herders, it is now believed that retaliatory killing of wildlife rivals commercial poaching as the greatest threat to the continued existence of the Chang Tang region's large fauna. Human-wildlife conflict reduction strategies and wildlife conservation education programs must be devised and implemented in order to halt the retaliatory killing of wildlife by nomadic herders in the Chang Tang.

Abstract: This handbook provides an introduction to snow leopard population survey techniques, followed by a detailed account of camera trapping methods.During the 2002 through 2004 winter field seasons, the Snow Leopard Conservancy experimented with infrared camera trapping techniques to define a methodology suitable for the high altitude environment.
In 2001 and 2002, much of our time was spent familiarizing ourselves with various infrared camera traps, their operation and setup, and comparing the effectiveness of different models and sensor types. We placed infrared camera traps along frequently used travel corridors at or near scent-sprayed rocks (rock scents) and scrape sites within 16 km2 sampling cells between January and March in 2003 and 2004. A total of 66 and 49 captures of snow leopards were tallied during 2003 and 2004, resulting in an overall capture success of 8.91 and 5.63 individuals per 100 trap-nights, respectively. Capture probabilities ranged from 0.33 to 0.46. Density estimates ranged from 8.49 ± 0.22 individuals per 100 km2 in 2003 to 4.45 ± 0.16 in 2004, with the disparity between years largely attributed to different trapping densities. Snow leopard abundance estimates were calculated using the computer program CAPTURE.
