Abstract
The present study was conducted on freshwater bodies of Rawalakot in order to explore the algal floral diversity and its role to determine water quality. The randomly selected 5 sites were used for the collection of algal samples on monthly basis from January 2017 to December 2018.The results showed that algal flora of the study area consisted of 205 algal species distributed across 61 genera, 43 families, 27 orders, 9 classes and 7 divisions. The largest divisions with respect to number of species were Bacillariophyta 97, Chlorophyta 79, Cyanophyta 19, Euglenophyta 5, Charophyta 3, Glaucophyta and Dinophyta 1 species each. In the present study, Palmer (1969) algal genus pollution index was employed to study the water quality. The total score of Algal Genus Pollution Index of station I, II, III, IV and V were 14, 9, 10, 18 and 25 respectively. It was assessed during this research that station I has moderate organic pollution while station II and III showed lack of organic pollution. Sampling Station III indicated probable organic pollution and station V indicated confirm high organic pollution. Algal Genus index revealed that the water quality of station I, III and V was affected from anthropogenic activities and needs to be managed.
