The Uttarakhand Forest Department has officially recorded smooth-coated otters in Nandhaur Wildlife Sanctuary for the first time. The rare semi-aquatic mammals were captured through camera traps and mobile footage during patrolling in Nainital district. The sighting is being viewed as an important sign of a healthy freshwater ecosystem in the Terai-Bhabar landscape.
Significance of the Sighting
The presence of smooth-coated otters indicates clean and unpolluted water bodies. Otters are considered bio-indicators because they survive only in pristine freshwater habitats with abundant prey. Their appearance suggests that the rivers and streams inside the sanctuary support a strong aquatic food chain.
Conservation Value of Nandhaur
Nandhaur Wildlife Sanctuary functions as a vital corridor between the Shivalik and Terai regions. It supports species that depend on both land and water habitats. The sanctuary has seen stronger monitoring and protection in recent years, and officials believe this has improved conditions for wildlife.
Species Profile and Threat Status
Smooth-coated otters are skilled aquatic hunters. Their diet mainly includes fish, though they may also eat frogs and other small aquatic animals. They use sensitive whiskers to detect prey in muddy or dark waters. The species is listed as vulnerable on the IUCN Red List, making habitat protection important for its survival.
Protection Measures and Local Appeal
Following the sighting, the forest department urged local communities and visitors to avoid polluting streams and rivulets inside the sanctuary. Officials stressed that clean freshwater is essential for otter survival and for maintaining the wider biodiversity of the area.
