Overview

• The Delhi Development Authority is conducting the survey from September 25 to 27 across Yamuna, Kalindi, Aravalli, Tilpath Valley, Tughlaqabad, Kamla Nehru Ridge, and Neela Hauz biodiversity parks.
• Officials say the count will assess species diversity as a proxy for water quality and overall wetland health following years of restoration work.
• Teams of scientists, university students and volunteers are documenting dragonflies and damselflies that help regulate mosquito and agricultural pest populations.
• Last year’s baseline recorded the highest species diversity at Yamuna Biodiversity Park with 21 species and the lowest at Neela Hauz with five.
• Authorities plan to release the park-by-park results on September 27 as part of Wildlife Week outreach.
