The Delhi government is pushing for the Neeli Jheel in Asola Bhatti Wildlife Sanctuary to be designated as a Ramsar site, having identified 250 bird species, including 58 water species. A survey conducted in February by Wetlands International South Asia highlighted the area's significant biological diversity and the presence of endangered species, which are crucial for Ramsar designation. Among the vulnerable species are the common pochard and river tern, while endangered species include the Egyptian vulture and steppe eagle. The critically endangered White-rumped vulture and Red-headed vulture were also spotted. Delhi Environment Minister Manjinder Singh Sirsa confirmed that the assessment is part of a broader effort to protect the region's biodiversity. Since Neeli Jheel is a trans-boundary wetland, the Delhi government is coordinating with the Haryana government, which is also eager to pursue Ramsar recognition. A joint report will be submitted to the central government once Haryana completes its assessment. Despite having over 1,300 water bodies, many in Delhi have been encroached upon or dried up, prompting ongoing efforts to revive and protect these vital resources.
