The Roodbast Wetland in Babolsar city is a crucial source of agricultural water and supports various living organisms near human settlements. Preserving the quality of this habitat is vital for both natural and human reasons. This study investigates the ecological status of Roodbast Wetland using algae as biological indicators of pollution. Diverse samplings were conducted in different seasons. Pollution levels were assessed using the Palmer index and various biological indicators. The study cataloged 81 genera across 7 phyla of algae. Chlorophyta had the highest species diversity, while Chrysophyta had the fewest. Peak algae proliferation occurred in summer and spring. Chlorophyta and Bacillariophyta were predominant throughout most of the year. In summer, Palmer’s pollution index peaked at stations 3 and 4, with a value of 35. In winter, stations 2, 4, and 5 showed minimal pollution with indices of 6, 9, and 7, respectively. During summer and autumn, all stations recorded Palmer indices exceeding 24. The primary cause of wetland pollution in spring is the influx of sub-branches from Babolrood, carrying village sewage and agricultural runoff. The rise in pollution in summer and autumn is due to elevated water temperatures, reduced rainfall, and increased extraction of lagoon water for rice replanting.
