This article was conducted as part of the hydroelectric power plant project planned for the Dimçayı basin in the Dim Valley (Antalya-Alanya), with the aim of identifying Chara specimens collected during expert fieldwork for the purpose of determining possible new taxa belonging to this genus in Türkiye. According to the findings, Chara squamosa has been recorded for the first time in the macrophyte flora of Türkiye. The species' habitat within the river system has been identified as a Channelmire type from a geomorphological-hydrological perspective; it is characterized by eutrophic vegetation cover in fast-flowing rivers. In light of these data, a contribution has been made to the ecology and sociology of the species classified as “Data Deficient (DD)” by the International Union for Conservation of Nature (IUCN). Factors threatening the survival of the species include: the lack of comprehensive protection status for its habitat, tourism activities exceeding the area's carrying capacity, a significant decrease in the flow of natural streams reaching the sea due to the large amount of water retained by the dam, unconscious water use in agricultural activities carried out in the area, and the discharge of reservoir waste from the province of Alanya-Antalya into the stream. Sustainable conservation approaches to address these threats have been proposed. With the addition of the species Chara squamosa, the number of Chara taxon groups in Türkiye has increased to 16, while the number of taxon groups in Türkiye's stoneworts has risen to 19, belonging to three genera.
