Abstract:

Pat Desert of Sanghar and Khairpur districts with a length of 80 km were examined for water quality and flora. Wells, lakes, artificial water reservoirs and saltpans were investigated. There was wide variation in water quality in the terms of conductivity and pH, the conductivity ranged from 114.3-208 mS/cm and pH from 7.52-10.8. Based on the water quality and soil texture the area is divided into three portions: (1) Silty and sandy zone (Rohi), (2) Pat Desert (Acharo Thar), and (3) Loose sand dunes (Draens). The alkaline lake water is used for preparing trona (Washing Soda). During the survey, 10 species of semi aquatic and aquatic plants were found. Algal flora revealed the presence of 64 species, including 37 species of Cyanophyta, 16 of Volvocophyta, one species of Dinophyta, 4 species of Bacillarophyta, 4 of Chlorophyta and 2 of Charophyta.
