The present study involves the flora of the Estil wetland and its surroundings in Astara, northwest Iran. During ۲۰۰۶-۰۷, we examined the plant specimens collected in this area and determined that there are ۲۴۷ vascular plant taxa (۲۲۹ species, ۱۱ subspecies, and seven varieties) in ۱۷۰ genera and ۶۰ families. The largest families are Poaceae (۲۷ taxa), Asteraceae (۲۶), and Brassicaceae (۲۱). Genera represented by the greatest number of species are Ranunculus (۷), Cyperus (۷) and Polygonum (۶). From the chronological point of view, the largest proportion of the flora belongs to the pluriregional elements. The number of endemic taxa within the study area is ۱۱ (۴.۵%). Using all references used, eight species and nine species are reported for the first time for the flora of northern Iran and Guilan Province, respectively.
