The snow leopard Panthera uncia is globally threatened and reliable information on its abundance, distribution and prey species is a prerequisite for its conservation. In October–November 2014 we assessed the distribution of the snow leopard in the recently established Api Nampa Conservation Area in the Nepal Himalayas. Within selected blocks we conducted sign surveys and counted the number of bharal Pseudois nayaur, its principal wild prey, along transects totalling 106 km. We recorded 203 putative snow leopard signs at an encounter rate of 1.91 signs/km. Generalized linear models of the number of signs detected per transect showed that elevation had a positive influence and human activities a negative influence on sign encounter rate; prey abundance had only a weak positive influence on sign encounter rate. Within the effectively surveyed area of c. 200 km2, we counted 527 bharal at an estimated density of 2.28 animals/km2. Recruitment of bharal was low, estimated at 48 kids/100 adult females, most likely a result of poor or overgrazed rangeland. We estimate the total number of bharal in this conservation area to be > 1,000, a prey base that could sustain 6–9 snow leopards. Based on our field observations, we identified human disturbance and habitat degradation associated with extraction of non-timber forest products, livestock grazing, and poaching as the main threats to the snow leopard. Standardized sign surveys, preferably supplemented by sampling with remote cameras or with genetic analysis of scats would provide robust baseline information on the abundance of snow leopards in this conservation area.

The herpetofauna of Nepal have been historically understudied, and although previous studies have reported on bioinventory surveys of the Kathmandu Valley, few have surveyed widely during the peak monsoon season. In addition, past studies largely neglected to survey intact forest habitats. Here we conduct a comprehensive field survey of the herpetofauna of the Kathmandu Valley, Nepal, with an emphasis on the surrounding foothills containing intact forest habitat. We record natural history and distribution data for seven species of amphibians and four species of reptiles. We also use mitochondrial sequence data to confirm the phylogenetic placement of two frog species, Megophrys (Xenophrys) parva and Duttaphrynus melanostictus. Using phylogenetic and morphological data we assign Megophrys parva from the Kathmandu Valley to Megophrys zhangi. We find that while this species shares a haplotype with its sister species, Megophrys monticola, morphological data align the individuals from the Kathmandu Valley with M. zhangi from Tibet. We find that M. zhangi exhibits no phylogenetic structure within the Kathmandu Valley, and wider sampling is needed throughout the Himalayas to determine its full range. These findings support the hypothesis that molecular sequence data will lead to the discovery of cryptic species in Nepal and facilitate the revision of species taxonomy. [ABSTRACT FROM AUTHOR]
