Explanation:

Basai wetland is encircled by Sector 102, Dhanwapur and Basai village from west, north and south directions in Gurugram district of Haryana. The wetland is permanent shallow wetland covering an area of about 250 acres. Rain, irrigation and sewage water in turn keep the wetland inundated round the year.The wetland was “discovered” as a birdwatching destination in 2001 when ornithologist and author Bill Harvey made a pit stop by the Basai railway track, en route to the Sultanpur National Park for a morning round of birdwatching. A 2001 field report of the Delhi Bird Club mentions that the Basai wetland covered an area bigger than Sultanpur jheel, a landmark bird sanctuary a few kilometres further down the Gurugram-Sultanpur road.The wetland supports a high diversity of birds including migratory ones. It has been recognised as an Important Bird and Biodiversity Area. In May 2017, eBird has recorded 282 bird species at the site including many listed in Threatened category by IUCN. The area around the wetland also provides refuse to wild animals.
