Résumé
There are currently about 1000 snow leopards in Mongolia with an overall density of 1.10 cats per 100 km2 of occupied habitat. These cats occupy an area range of probably less than 90 thousand km2. The snow leopards commonly use terrain that is extremely rugged, in the same habitat where yak graze and often unguarded. Consequently, they, along with horses, are often killed by snow leopard, more so than other large livestock. During our study, 168 faecal samples of the snow leopard were collected and analysed. Results show that ibex made up 38.7% of the total diet, small mammals 4.6%, red deer 2.4%, marmot 7.1%, and domestic livestock 31% (including sheep 17.3%, horse 5.4%, cow 4.8%, and goat 3.6%). In addition to prey, vegetation (14.9%) and soil (2.3%) were also found in the faecal samples.
