Assam bird sanctuary records 72% decline in bird species count in 27 years

The Hindu  

GUWAHATI The number of avian species at a major wetland in north-eastern Assam declined by almost 72% in 27 years, a study has revealed. Another survey carried out between April 2017 and March 2018 recorded 120 species of birds apart from 133 species of macrophytes, 68 species of fish, and seven species of aquatic ferns. The study listed a few anthropogenic activities as the causes of the decline in the bird species count at BBBS. The cultivation of crops with high-decibel machines close to the edge of the water body, and the use of the bird sanctuary as a pasture area have also forced the resident and migratory birds to “change their foraging and/or breeding grounds to somewhere else”, the study said. “The degradation of wetland habitat may cause the water table to drop, the food chain to get disrupted, the migratory bird populations to decline, and the nutrient cycle to slow down, all of which are detrimental to the environment, ecosystem, and human beings,” the study said, advocating intense conservation efforts at the BBBS.
