Kaziranga Wildlife Sanctuary

Syllabus subtopic: Conservation, environmental pollution and degradation, environmental impact assessment

Prelims and Mains focus: about the findings of the survey and its significance; about Kaziranga Wildlife Sanctuary: flora and fauna found in it

News: Kaziranga recorded 96 species of wetland birds — one of the highest for wildlife reserves in India, according to the second wetland bird count conducted on January 9­-10.

Background

The first wetland bird survey in Kaziranga, a UNESCO World Heritage Site since 1985, was conducted in 2018. Rabindra Sarma, the park's research officer said avian surveys could have been done in the 115­year-old Kaziranga earlier, but no records were maintained.

Key findings of the census

  • The survey covered four ranges of the park — Agoratoli, Bagori, Kohora and Burapahar.

  • More than half the birds (9,924) and 85 of the 96 species were recorded in Agoratoli Range. This was because Sohola, the largest of Kaziranga's 92 perennial wetlands, is in this range.

  • The survey registered a total of 19,225 birds belonging to 96 species under 80 families. The first waterfowl census in 2018 had yielded 10,412 birds covering 80 species, belonging to 21 families.

  • With 6,181 individuals, the bar­headed goose led the species count, followed by the common teal at 1,557 and northern pintail at 1,359. All three belong to the family anatidae.

  • The other species with sizeable numbers include gadwall, common coot, lesser whistling duck, Indian spot­billed duck, little cormorant, ferruginous duck, tufted duck, Eurasian wigeon, Asian openbill, northern lapwing, ruddy shelduck and spot­billed pelican.

Significance of the survey

Data on avian wealth is important because the wetlands nourish Kaziranga's ecosystem. Increase or decrease in the number of birds is indicative of the park's health.
