Camera trapping is always an arduous task – but our researchers faced exceptional challenges during this pilot survey. The group set out shortly after heavy rains and floods in Himachal Pradesh, the province where the National Park is located, which destroyed many of the wooden bridges built by the Forest Department. Teams had to wade across waist-deep (and cold) water while carrying heavy equipment above their heads to avoid any damage. Even the trails that weren’t washed out were overgrown with grass taller than an average person. Already narrow paths were barely visible, with steep cliffs on the other side!

We also hope to better understand how human development and climate change may affect this in the future. Typically, common leopards in the study region are found below the treeline and hunt prey such as goral, a relatively small-bodied mountain ungulate. In contrast, snow leopards are found above the treeline and hunt the larger blue sheep. However, at elevations where both species occur, we are unsure if they hunt the same prey and compete for resources. Somewhat unexpectedly, our researchers recorded a high number of common leopards in the Tirthan Valley, while we did not detect any snow leopards. This may be due to insufficient sampling of snow leopard habitats in this area since much of the valley was inaccessible and unsafe due to the heavy rains and floods. Another surprise was the detection of a common leopard scent marking at 4,000 meters elevation in the same location where a snow leopard marking was found during a 2019 survey. This is quite high up for a common leopard, though these are preliminary observations. Along with common leopards and snow leopards, our researchers were delighted to find the Western Tragopan, a rare bird that is classified as Vulnerable. Because this survey spanned a significant altitudinal gradient, including lower elevations than we usually set out cameras in, we also spotted several species we don’t often see or associate with snow leopards, like rhesus macaques. The Great Himalayan National Park is an ecologically diverse landscape and this survey beautifully showcases the habitat transitioning along elevation gradients, including broadleaf evergreen forests, coniferous forests, grassy alpine meadows with rocky outcrops and glacial peaks.

We would like to thank the Himachal Pradesh Forest Department for providing permits to carry out this work. We also thank several forest guards, local guides and porters, and the NCF field team from Kibber for carrying out the fieldwork.
