Site description Basai wetlands are located close to Delhi, about 2 km west of Gurgaon and 8 km east of Sultanpur National Park, in Haryana state. One of the outstanding features of the site is the relative tameness of the birds that utilize it. The main source of water is from a breached water channel bringing waste water and supposedly treated sewage from the Gurgaon Water and Sewage Works. This has created a permanent shallow wetland of about 250 acres comprising open water, Water Hyacinth and Typha reed beds. Rain water and the channeling of the water by farmers to irrigate their crops (particularly rice) regularly floods an area of up to 1 sq. km in the monsoon. Paspalum sp. grows extensively, and is cut for fodder by villagers. This provides an ideal grazing sward for a significant flock of wintering Bar-headed Geese Anser indicus. There are several bare, salt-laden fallow fields and some low thorn scrub. Along the railway line, borrow pits have formed small ponds and reed beds. Gurgaon Water and Sewage Works have recently constructed a deep-water reservoir close to the Ashram on the Sultanpur road, which now attracts diving duck, cormorants and grebes. The core area is predominantly covered with Water Hyacinth, large Typha reed beds and some fields of Paspalum grass. Adjoining it are areas of poor agricultural land, given over seasonally to rice, wheat and mustard. There is also infertile fallow land with Salicornia and Acacia scrub, particularly in the borrow pits. There are very few trees, but they include fruiting figs near the Temple and the Ashram. The members of the Delhi Bird Club regularly monitor the bird population of this IBA. Bird ringing camps, with the collaboration of BNHS, are organized twice a year.
