Visitor Satisfaction and Opportunity Survey, Manang, Nepal: Market Opportunities for Linking Community-Based Ecotourism with the Conservation of Snow Leopards in the Annpurna Conservation Area. Report prepared for WWF-Nepal Programme (Vol. SLC Field Document Series No 3).
Abstract: For the past two decades, the Manang or Nyeshang Valley has become one of the most popular
trekking routes in Nepal, attracting over 15,000 trekkers annually (Ale, 2001). The 21-day
circular trek takes the visitor from the lush southern slopes of the Annapurna massif around to
its dry northern slopes more reminiscent of Tibet, through a landscape of spectacular mountain
scenes, interesting villages and diverse cultures. The Manang region also offers prime habitat
for the endangered snow leopard, supporting an estimated 4.8 – 6.7 snow leopards per 100 sq.
km (Oli 1992). This high density has been attributed to the abundance of blue sheep, the snow
leopard's primary large prey species across the Himalayan Mountains and Tibetan Plateau.

Abstract: Describes and Quantifies snow leopard marking behaviour, based primarily on sign, gatherd during a four year study in Nepal. Emphasis is on scrapes and spray markings, detailing their frequency of occurence realtive to habitat characteristics and season. Both sexes mark intensively, sign abundance is associated with intensity of use, and sign is concentrated along breaks in terrain.

Ale S. (2005). Have snow leopards made a comeback to the Everest region of Nepal?.
Abstract: In the 1960s, the endangered snow leopard was locally extirpated from the Sagarmatha (Mt. Everest) region of Nepal. In this Sherpa-inhabited high Himalaya, the flourishing tourism since the ascent of Mt Everest in 1953, has caused both prosperity and adverse impacts, the concern that catalyzed the establishment of Mt. Everest National Park in the region in 1976. In the late 1980s, there were reports that some transient snow leopards may have visited the area from adjoining Tibet, but no biological surveys exist to confirm the status of the cats and their prey. Have snow leopards finally returned to the top of the world? Exploring this question was the main purpose of this research project. We systematically walked altogether 24 sign transects covering over 13 km in length in three valleys, i.e. Namche, Phortse and Gokyo, of the park, and counted several snow leopard signs. The results indicated that snow leopards have made a comeback in the park in response to decades of protective measures, the virtual cessation of hunting and the recovery of the Himalayan tahr which is snow leopard's prey. The average sign density (4.2 signs/km and 2.5 sign sites/km) was comparable to that reported from other parts of the cats' range in the Himalaya. On this basis, we estimated the cat density in the Everest region between 1 to 3 cats per 100 sq km, a figure that was supported by different sets of pugmarks and actual sightings of snow leopards in the 60 km2 sample survey area. In the study area, tahr population had a low reproductive rate (e.g. kids-to-females ratio, 0.1, in Namche). Since predators can influence the size and the structure of prey species populations through mortality and through non-lethal effects or predation risk, snow leopards could have been the cause of the population dynamics of tahr in Sagarmtha, but this study could not confirm this speculation for which further probing may be required.
