The imbalance in the ecosystem of coastal region of Pakistan has undergone serious stress due to changes in Indus river regime as well
as unchecked industrial discharge into the coastal region. This study aimed to demonstrate the ecological imbalances at Gharo Creek,
one of the productive coastal zone of Karachi in the past. A total of 48 species of flora and 155 species of fauna were found in the
samples of 7 different sampling sites of Gharo Creek. The most abundant group was Mollusca (37.39%), followed by Crustacea 15.64
% and Nematoda 16.52 %. Egg mass, unidentified specimen, empty mucous tubes and Porifera constituted 2.37%, 1.25%, 1.00% and
0.75 % respectively. In Mollusca the most abundant group was Gastropoda (20.90%) followed by Pelecypoda (16.77%) and Annelida
(21.27%). No significant number of floral species was obtained except the members of the genus Chlorophyta( 33%).
