Site description (2004 baseline):
AVIFAUNA: Sur Sarovar Sanctuary supports more than 30,000 waterbirds and a large heronry of Grey Heron Ardea cinerea, egrets Egretta spp. and cormorants Phalacrocorax spp., but infestation of Water Hyacinth in the lake and the drainage system has badly affected the foraging grounds of these birds. During a brief survey of the site in January 1991, 52 species were seen in this Sanctuary (Rahmani and Arora 1991). Most of the common waterfowl of north India are found in this Sanctuary, namely Northern Pintail Anas acuta, Wigeon A. penelope, Northern Shoveler A. clypeata, Gadwal A.strepera, Spotbilled Duck A. poecilorhyncha and Comb Duck Sarkidiornis melanotos. Four species of storks are found here: Painted Mycteria leucocephala, Openbill Anastomus oscitans, Black-necked Ephippiorhynchus asiaticus and Lesser Adjutant Leptoptilos javanicus. Eurasian Spoonbill Platalea leucorodia, White Ibis Threskiornis melanocephala, four species of egrets, two species of herons, and three species of cormorants can easily be seen from the road around the reservoir. According to forest officials, pelicans (possibly Great White Pelican Pelecanus onocrotalus) are also seen sometimes. Earlier, fishermen used to chase them away, but since the declaration of the sanctuary, the birds are left undisturbed. Earlier, very few ‘heronry’ species used to breed in Sur Sarovar, but in 1990, large numbers of egrets, cormorants, herons, Eurasian Spoonbills and White Ibis started nesting on the Prosopis trees present on the islands and flooded areas. There could have been more than 2,000 nests. Since then, regular breeding is seen but the number of nests fluctuates, depending upon the water conditions and food availability in the area. The globally threatened Sarus Crane Grus antigone is also seen, but it is not known whether it breeds in the Sanctuary or not. A few Greater Spotted Eagles Aquila clanga are seen frequently.
OTHER KEY FAUNA: Golden Jackal Canis aureus, Jungle Cat Felis chaus and Nilgai Boselaphus tragocamelus are found in the surrounding forests.
Hyena Hyaena hyaena is also reported, but rarely seen. There is no mammal or reptile species of high conservation concern in the area.
The population of migratory birds during the peak of winter needs to be estimated, and their population monitored at regular intervals to record fluctuation in species composition. Grazing pressure from livestock from the six surrounding villages should be regulated. Nearly 70% to 80% of the waterbody is covered with weeds, particularly Water Hyacinth, despite constant dredging. The Irrigation Department owns the land, so coordination is required, particularly to maintain adequate water levels for optimum removal of Water Hyacinth. A drain from the Agra canal comes down to Sur Sarovar from Okhla, carrying Water Hyacinth along with it. This means that re-establishment of the weed is certain even after it is removed from this waterbody. A chain link gate to prevent Water Hyacinth entering the lake has been broken. In December 2000, 20-25% of the lake was cleared of Hyacinth, manually through people’s participation. But this problem needs constant attention if this important wetland IBA is to be saved.
