Site description (2004 baseline):
AVIFAUNA: A total of 182 bird species has been recorded from the Kole wetlands, of which 53 are winter visitors (Sivaperuman and Jayson 2000, Nameer 1994, Nameer 2002, Jayson 2002). The importance of these wetlands can be judged from the fact that between March 1988 and May 2001, Nameer (2002) recorded 21 bird species not recorded by Ali (1969). Of these, seven species i.e. Eurasian Spoonbill Platalea leucorodia, Comb Duck Sarkidiornis melanotos, White-tailed Lapwing Vanellus leucurus, Grey-headed Lapwing Vanellus cinereus, Plain Sand Martin Riparia paludicola, Common Starling Sturnus vulgaris and Red Munia Estrilda amandava were recorded for the first time in Kerala (Nameer 2002). Kole wetland has been monitored by an organization called Nature Education Society, Trichur (NEST) (Nameer 1993). In 1992, NEST recorded 23,605 birds, including 50 species of waterbirds and four raptors (Jayson 2002). Next year, 54,000 birds, including 48 species of wetland birds were recorded (Nameer 1993). Kole wetlands may have the largest roost of terns in India. Nameer (2002) estimated about 25,000, including 10,000 Whiskered Terns Chlidonias hybridus. According to Wetlands International (2002), 1% population threshold of Whiskered Tern in India is 1,000. Therefore, almost 10% of the population of this species congregates at Kole wetland. Other species seen above their 1% biogeographic population threshold are (number seen at Kole given in brackets): Garganey Anas querquedula (7,887), Little Egret Egretta garzetta (5,000) and Gull-billed Tern Gelochelidon nilotica (3,365). Sivaperuman and Jayson (2000) have reported Rufous Babbler Turdoides subrufus, a Western Ghats endemics found in tall grass and bamboo at the edge of forests (Grimmett et al. 1998). Kole wetland is selected as an IBA as it perfectly fits three criteria: A1: it has many globally Threatened and Near Threatened species; A4i: it has ³1% of the biogeographic population of Indian Whiskered Tern, Garganey and Gull-billed Tern, and A4iii: it has ³20,000 waterbirds.
OTHER KEY FAUNA: Data on other fauna are not available.
Kole is one of the largest and most important wetlands of Kerala. It is also one of the most threatened wetlands in the State. Reclamation of land and change in land use pattern are the most serious problems. Paddy fields are being converted to coconut, arecanut and banana plantations and other cash crops at an alarming rate. The marshes are being ‘developed’ and new constructions are cropping up. At many places, the wetland has been converted to brick-kilns, which has become a profitable small-scale industry. Added to this are, large scale poaching and trapping of birds and fish. Of the 12 Spot-billed Pelicans seen on January 15, 1993 by Nameer (1993), two were killed by poachers. The indiscriminate use of pesticides affects the bird population. Pesticides are also used to poison and capture birds for meat. Apart from this, setting fire to the natural vegetation in the area also adversely affects the breeding habitats of Rallidae, Sylviinae, Ploceinae and Estrildinae. As a very large number of people live in and directly benefit from Kole wetland, there is a great opportunity to develop it into a multiple-use wetland under the Ramsar Convention.
