In the high Himalayan wilderness of western Nepal, a major scientific wildlife survey is underway to uncover one of the most elusive big cats on Earth the snow leopard.

In the remote alpine landscapes of Dhorpatan Hunting Reserve, conservation teams have launched a large-scale camera trap study to estimate the population of snow leopards across one of Nepal’s most important high-altitude ecosystems.

The initiative marks one of the most structured and technologically advanced efforts ever conducted in the region to track the species, which is rarely seen due to its extremely secretive behavior and extreme habitat conditions.

Why Snow Leopard Counting Matters in Nepal

The snow leopard (Panthera uncia) is one of the most endangered and least understood big cats in the world. In Nepal, it inhabits remote Himalayan zones ranging from 3,000 to over 5,500 meters in altitude.

The population in Nepal is estimated to be between 300–400 individuals, but exact numbers remain uncertain due to the animal’s elusive nature.

In regions like Dhorpatan Hunting Reserve, conservationists believe snow leopards may be more abundant than previously recorded, making scientific population monitoring essential for:

• conservation planning
• habitat protection
• human-wildlife conflict reduction
• biodiversity research

Unlike other wildlife species, snow leopards cannot be counted through direct sightings. Instead, Nepal uses advanced scientific tools such as camera trapping, genetic analysis, and habitat mapping.

Camera Trap Survey Begins in Dhorpatan Hunting Reserve

The current snow leopard census in Dhorpatan Hunting Reserve is being conducted through a network of sensor-based camera traps installed across the high Himalayan terrain.

According to conservation officials, three separate technical teams have deployed a total of 56 motion-sensor cameras across key snow leopard habitats.

These cameras are installed at elevations ranging from 3,200 meters to 5,500 meters above sea level, covering steep cliffs, ridgelines, valleys, and potential denning areas. The survey marks the first structured attempt of its kind in Dhorpatan to scientifically estimate snow leopard population density.

How the Camera Trap System Works

The snow leopard monitoring system relies on motion-activated infrared cameras placed strategically across the landscape.

Key features of the system:

• Automatically captures images when movement is detected
• Operates in extreme cold and high-altitude conditions
• Records both day and night activity
• Stores images on memory cards for later analysis

Once installed, the cameras continuously operate for around 45 days, capturing wildlife activity without human interference.

The system is designed to minimize disturbance in the natural habitat while collecting accurate data on elusive species.

Where the Cameras Are Installed

The camera traps have been placed across six different hunting blocks within Dhorpatan.

These include remote alpine zones spread across:

• Baglung District
• Myagdi District
• Rukum District

These areas are known for rugged terrain, deep valleys, and high-altitude grasslands ideal habitats for snow leopards and their prey species such as blue sheep (bharal).

The cameras are specifically installed in:

• potential snow leopard dens
• cliff corridors
• prey movement routes
• ridge crossings
• forest edges near alpine zones

Field Operations in Extreme Himalayan Conditions

The installation process took approximately 15 days, carried out by technical experts, reserve staff, and wildlife enumerators.

Working in Dhorpatan’s terrain is extremely challenging due to:

• low oxygen levels at high altitude
• unpredictable weather conditions
• steep and unstable slopes
• limited communication access
• long travel distances between sites

Despite these challenges, teams successfully positioned all 56 cameras across the designated survey zones.

After installation, field teams returned to base stations to allow uninterrupted wildlife monitoring.

How Data Is Collected and Verified

The snow leopard census uses a combination of methods to ensure accuracy:

1. Camera Trap Images

Each camera captures photographs of passing animals. Snow leopards are identified through:

• unique fur spot patterns
• body size and shape
• tail markings
• movement behavior

2. Field Maintenance Visits

Every 15 days, technicians return to:

• replace batteries
• change memory cards
• check camera functionality

This ensures continuous data collection over the full survey period.

3. Genetic Analysis (Scat Collection)

Researchers also collect droppings (scat) found in forested and rocky areas.

These samples are sent to laboratories for:

• DNA testing
• individual identification
• population estimation

4. Jaw and Bone Assessment

In rare cases, physical remains found in the area may also be used for scientific identification.

Why Dhorpatan Is Important for Snow Leopards

Dhorpatan Hunting Reserve is Nepal’s only hunting reserve, but it also plays a critical role in conservation.

Despite its name, the reserve is a key biodiversity hotspot that supports:

• snow leopards
• Himalayan blue sheep
• musk deer
• Himalayan wolves
• pheasants and high-altitude birds

The combination of alpine meadows, rugged cliffs, and minimal human disturbance makes it an ideal habitat for snow leopards.

Experts believe that Dhorpatan may hold a more stable snow leopard population than previously documented, which makes the current survey particularly important.

Challenges in Snow Leopard Conservation in Nepal

Tracking snow leopards in Nepal is extremely complex due to several factors:

1. Remote Habitat

Snow leopards live in some of the most inaccessible regions of the Himalayas.

2. Low Population Density

They exist in very small, widely scattered populations.

3. Elusive Behavior

Snow leopards are solitary and avoid human contact.

4. Climate and Terrain

Harsh winters and steep landscapes make fieldwork difficult.

5. Human-Wildlife Conflict

Occasionally, snow leopards prey on livestock, leading to conflict with local herders.

Role of Local Communities

Local communities in and around Dhorpatan play a vital role in conservation efforts.

Many residents help by:

• reporting sightings
• protecting livestock enclosures
• supporting research teams
• participating in eco-tourism initiatives

Community involvement is considered essential for long-term snow leopard conservation success in Nepal.

Scientific Importance of the Survey

This camera trap survey is not just about counting animals — it contributes to broader conservation science.

The data will help:

• estimate population density
• map habitat distribution
• identify movement corridors
• understand breeding behavior
• improve conservation planning

It also contributes to global snow leopard research networks, as Nepal is one of the species’ core habitats.

Snow Leopard Habitat Across Nepal

Beyond Dhorpatan, snow leopards are found in several Himalayan regions, including:

• Annapurna Conservation Area
• Langtang National Park
• Sagarmatha region
• Dolpa region

However, each region has different population density and habitat conditions, making localized studies like the Dhorpatan survey extremely important.

What Happens After the 45-Day Survey?

Once the camera trapping period ends, scientists will:

1. Collect all memory cards
2. Process thousands of images
3. Identify individual snow leopards
4. Cross-check data with genetic samples
5. Estimate population size using statistical models

The final results will help shape conservation policy and future monitoring programs in Nepal.

Why This Study Matters for Nepal’s Conservation Future

Snow leopards are considered an indicator species, meaning their presence reflects the overall health of the Himalayan ecosystem.

Protecting them also helps conserve:

• alpine biodiversity
• water sources originating in glaciers
• fragile mountain ecosystems

For Nepal, which sits in the heart of the Himalayan biodiversity zone, studies like this are essential for balancing conservation and local livelihoods.

The snow leopard camera trap survey in Dhorpatan Hunting Reserve represents one of the most important wildlife monitoring initiatives in Nepal’s high Himalayas.

By combining modern technology with field expertise and community involvement, Nepal is taking significant steps toward understanding and protecting one of its most iconic and endangered species.

While the snow leopard remains one of the world’s most mysterious predators, efforts like this bring scientists closer to answering a crucial question:

How many snow leopards truly roam the Himalayas of Nepal?

The results from this study will not only shape conservation strategies but also strengthen Nepal’s position as a global leader in Himalayan biodiversity research.
