Why in news?
The latest bird census at Gujarat’s Nalsarovar Bird Sanctuary has counted more than 500,000 birds across about 200 species, a remarkable increase of 21 percent from the previous year. The surge is attributed to a temporary ban on boating and reduced tourist movement after a tragic boat accident in January 2024, allowing the wetlands to recover.
Background
Nalsarovar, located near Ahmedabad, is a Ramsar‑listed wetland and one of India’s largest bird sanctuaries. The shallow freshwater lake spreads over 120 square kilometres and attracts migratory birds from as far as Siberia, Central Asia and Europe. In January 2024 a boating accident at Harni lake prompted authorities to ban boating at Nalsarovar, drastically reducing human disturbance.
Key findings from the census
- Higher bird count: The census recorded over five lakh birds, up from about 4.1 lakh the previous year. Ornithologists noted an increase in both resident and migratory species.
- Rare sightings: Rare birds such as the Pale Martin, Australian stilt and Greater White‑fronted Goose were observed. However, populations of flamingos and cranes declined by roughly 20 percent, possibly due to changing water levels.
- Habitat improvements: With boating halted, noise levels dropped and 250 boating operators ceased operations, allowing birds to rest undisturbed. Water levels were maintained around 3.5 feet by regulating flows from the Narmada canal, creating optimal feeding conditions.
The results highlight how reduced human interference and effective water management can enhance biodiversity. As authorities consider resuming boating, conservationists urge that tourism be regulated to preserve Nalsarovar’s delicate ecosystem.
