Abstract
The article presents the results of the study of autumn algae flora and coastal vegetation of the Big and Small Taldykol lakes. According to the results of the study, the autumn algae flora includes 36 species including cyanobacteria. Most algae are beta-mesasaprobic species. Species diversity in Little Taldykol was low, which indicates the poor ecological condition of the lake in autumn. There are 35 species of coastal plants from 11 genera. Coastal vegetation of the studied areas includes mainly weeds and adventitious plants that are common in Central Kazakhstan. Garbage plants in the community have a negative impact on the study area, causing the spread of weeds.
