Nanda Devi Expedition Uncovers Rich Biodiversity

The fourth decadal Nanda Devi Biodiversity Monitoring Expedition has concluded its extensive 22-day scientific survey. A 32-member team of scientists, technical experts, and officials completed an 88-km journey through the UNESCO World Heritage Site in Chamoli district. The expedition traversed elevations from 2,000 to 4,000 meters, documenting wildlife and ecological changes.

During the survey, researchers recorded direct sightings of numerous species, including Himalayan tahr, blue sheep, musk deer, and Himalayan black bears. Indirect evidence of snow leopards and other mammals was also found. Bird surveys confirmed the presence of Himalayan monal and golden eagles. Over 100 species of flowering plants were documented, alongside studies on alpine vegetation, medicinal plants, and insect pollinators.

For the first time, the expedition comprehensively surveyed entomofauna, including butterflies and pollution-sensitive lichens. Advanced technologies like camera traps, drones, and GIS were employed to monitor wildlife and glacier dynamics. The team also engaged with local residents to discuss conservation efforts and ecotourism, leveraging traditional knowledge.

Nanda Devi National Park has remained largely protected from human interference since 1982. This scientific expedition, only the fourth since the park's core zone closure, is vital for assessing the health of its fragile Himalayan ecosystem.
