Three of Asia’s most formidable predators share territory in a remote Nepal valley by eating different prey, according to a new study. Researchers found that diet, not time or space, is what keeps snow leopards (Panthera uncia), common leopards (Panthera pardus), and Himalayan wolves (Canis lupus chanco) from coming into direct conflict.
The study, published in PLOS One, drew on more than six years of camera-trapping and scat analysis in the Lapchi Valley of the Gaurishankar Conservation Area in Nepal’ s central Himalayas. Researchers identified each predator’s diet by analyzing fecal DNA and examining prey hair under a microscope.
Snow leopards fed mainly on wild ungulates, including blue sheep (Pseudois nayaur), musk deer (Moschus leucogaster), Himalayan tahr (Hemitragus jemlahicus), and Himalayan serow (Capricornis sumatraensis). Blue sheep alone made up nearly half their diet.
Leopards relied heavily on livestock and animals associated with human settlements, including dogs, though barking deer (Muntiacus muntjak) and goral (Naemorhedus goral) also appeared in their scats.
Himalayan wolves ate a mix of wild prey like blue sheep and musk deer as well as livestock such as goats, horses, and yaks (Bos grunniens).
Dietary overlap between snow leopards and wolves was substantial, while leopards showed far less overlap with either species. All three predators were active mostly at night and used overlapping terrain.
“The biggest surprise is that space and time are not what keep peace among the top three predators,” lead author Narayan Prasad Koju of Nepal Engineering College told Mongabay in an email. “The fact that diet alone is doing so much of the work while the animals are essentially sharing the same space at the same hours is an interesting finding.”
The study also documented a potential threat to that balance. Leopards have been expanding into high-altitude snow leopard habitat, likely driven by climate change, shifting treelines, and infrastructure development at lower elevations.
Madhu Chetri, a researcher at the National Trust for Nature Conservation who has studied predator overlap in the Gaurishankar Conservation Area, told Mongabay that up to half of the current snow leopard habitat in the Himalayas could be altered by shifting treelines, shrinking the alpine zones snow leopards depend on.
When livestock is killed, herders may retaliate against snow leopards even when leopards are responsible, Koju said, because snow leopards are a more familiar target in that landscape.
Nepal is home to an estimated 397 snow leopards, according to a 2025 government survey cited in the study. Both snow leopards and common leopards are classified as vulnerable on the IUCN Red List.
Koju said the most urgent conservation priorities are protecting wild prey populations and reducing human-wildlife conflict through predator-proof corrals and better compensation schemes for herders. In the Lapchi Valley, livestock are currently grazed with no corrals or containment.
“When wild prey declines, all three predators shift toward livestock, which triggers retaliatory killings and destabilizes the whole system,” he said.
