�� TAMIL NADUTAMIL NADUA profile of wetlands in Tamil Nadu

Habitat features

2Tamil Nadu has 1615.11 km (IRS & SAC, 1998) area under

wetlands constituting 1.24% of the total geographic area of

the state. It includes 1175 wetlands of the size 56.25 ha and

above.

According to an estimate, the number of wetlands of the size

two ha and above in the eight select districts are 4779, 2

covering an area of 731.72 km . These are shown in pages

162 to 169. Ponds/ lakes outnumber all other types of

wetlands. However, reservoirs cover large extent. Turbidity

is low in reservoirs, whereas it is medium to high in ponds/

lakes.

Turbidity



Wetlands

The area under wetland in the eight districts ranges between 0.42% (Tirunelveli) and 5.11% (Pudukkottai). Threecategories of wetlands are found, namely ponds/lakes, reservoirs and waterlogged areas. Waterlogged category is the dominating type of wetland in Thanjavur district, whereas it is reservoir in Kanyakumari district. All other districts have more ponds/lakes. It is striking that all the districts have smaller wetlands (smaller than 56.25 ha.) several times more than the larger ones.

Summer recession of water

Summer recession of water varied from 0.56% in Kanyakumari to 100% in Pudukkottai. In all other districts, excepting Tirunelveli, the recession is between 50-80%. Such a landscape level recession will have its bearing on the aquatic birds fully dependent on wetlands.

Attributes of wetlands and environmental contamination

Turbidity

Among the wetlands of the districts studied in Tamil Nadu, those in three districts, namely Chengalpet, Kanyakumariand Tirunelveli have low turbidity.Thanjavur, Vellore and Cuddalore districts have high proportion of wetlands under medium turbidity.
