ECO-BIOLOGICAL STATUS OF KALANKAR LAKE DHORO NARO SANGHAR UMERKOT WITH REFERENCE TO NATURAL RESOURCES MANAGEMENT PLANT
Abstract
Kalankar Lake is a natural freshwater wetland located at coordinates 25°34′43.07” N latitude and 69°35′28.99” E longitude, near the community of Dhoro Naro, situated in Sanghar and Umerkot districts, Sindh Pakistan. The Lake provides habitat to diversity of aquatic, amphibian and terrestrial biota. Physico-chemical and biological status of the lake has been studied to find out the impacts of climate change and freshwater scarcity issues. The water temperature was between 29-31°C, Transparency/ Turbidity of water 18-39 cm, pH 7.3-7.7, Alkalinity 145-180mg/l, Salinity 330-360 ppm, TDS 855-942mg/l and Conductivity (405-476µc/m. 21 species of phytoplankton and algal belong to three classes with great representation of Cyanophyta (51.5), Chlorophyta (32.5) and Bacillariophyta (16%). Invertebrate fauna consisting of Rotifer 47.5%, Arthropoda 31% and Mollusca 21.5% were reported. 13 macrophyte were existing during study. 18 fish species were observed from the lake. The dominant species belonged to Cypriniforms, Cichilidiformes and Anabantiformes. Very few species of aquatic fauna and flora have been reported from the lake, it may be due to insufficient supply of freshwater in the lake. The authorities are urged to give special attention to the eco-biological status of the lake for conservation, protection and restoration purposes of this natural heritage of Sindh Pakistan.
