DECLARATION OF DUGONG CONSERVATION RESERVE IN PALK BAY OF THE WILD LIFE

(PROTECTION) ACT, 1972

[G.O. Ms. No.165, Environment, Climate Change and Forests (FR.5), 21st September 2022,

Ćர½டாÒ 4, ĀபÐĉĄ, ÖĉவÈčவÄ ஆ¾Ă-2053.]

No. II(2)/ECCF/768(a)/2022.

WHEREAS, the Government of Tamil Nadu considers that the area described in the Schedule below is of adequate

ecological and biological signifi cance for the purpose of protecting, propagating, developing wildlife and its environment.

AND WHEREAS, Palk Bay is a shallow bay located on the southeast coast of India. Its environment is unique in the sense

that it is almost an enclosed bay with input from several small rivers along its coast. The marshlands of this backwater system

support lush growth of mangrove forests which harbour a wide variety of birds both native and migratory. The backwaters

act as breeding and feeding grounds for a wide variety of fi n-fi sh and shell-fi sh. The enclosed nature of the bay provides the

ideal habitat for dugongs, dolphins, porpoises and turtles to frequent the region.

AND WHEREAS, the region is rich in biodiversity having all the important groups of fl ora and fauna in its environment.

The total number of species and their endemic form given in parentheses are Foraminifera 51 (2), Tintinnids 12, Flora 143

(1), Sponges 275 (31), Coelenterates other than corals 123 (49), Stony corals 128 (43), Polyzoa 100 (15), Polychaeta 75

(22), Insecta 1 (1), Crustacea 651 (159), Mollusca 733 (26), Echinodermata 274 (2), Prochordata 66 (41), Fishes 580, Turtles

5, Birds 61, and Mammals 11.

AND WHEREAS, the endangered species Dugong (Dugong dugon) lives within 10 metre depth not far from the shore,

usually in groups limited to 5 to 7 individuals among the sea grass beds. The sea grass, Cymodocea, is their primary diet.

Their presence has been continuously recorded in the Palk Bay. Dugongs can grow to a size of over 300 kilograms measuring

3.0 to 3.5 metre in length. Due to uncontrolled fi shing carried out in the past and also due to reduction in their grazing area

viz., the sea grass Cymodocea, their numbers have come down drastically.

AND WHEREAS, it was scientifi cally proved that the coastal areas of Thanjavur and Pudukottai districts in Palk Bay is

covered by around 12,250 hectares of seagrass beds, and protecting seagrass beds and dugongs in this area, will also

help for the breeding of commercially valuable fi nfi shes, crabs and shrimps, thereby benefi tting thousands of small scale and

marginal fi shermen, who depend on fi shery productivity for their daily livelihood in the nearshore areas.
