BSIP scientists trace Kaziranga's ecological history from pollen in swamp sediment

Scientists of the Birbal Sahni Institute of Palaeosciences used pollen and dung-fungal spores in a sediment core from the Sohola swamp to build the first long-term palaeoecological record of Kaziranga National Park, the DST said on 3 February 2026.

Summary

The Department of Science and Technology said on 3 February 2026 that scientists of the Birbal Sahni Institute of Palaeosciences (BSIP), an autonomous DST institute, have produced the first long-term palaeoecological records linked to herbivory from Kaziranga National Park in Assam. They studied a sediment core just over a metre long from the Sohola swamp, using pollen grains and spores of fungi that grow on animal dung to trace how climate, vegetation, invasive species and herbivores shaped the home of the one-horned rhino.
