A new record of the rare species <i>Chara</i> canescens Loisel (<i>Charophyta</i>, <i>Charales</i>) in Ukraine (Odesa Region, Kuialnytskyi National Nature Park)

Data on the new locality of Chara canescens Loisel., a rare species included in the Red Data Book of Ukraine, are presented. A new locality for Ukraine was discovered at the mouth of the small Kubanka River, which flows into the Kuialnik Estuary in the Kuialnytskyi National Nature Park (Odesa Region). The main natural factors limiting the existence of C. canescens in the discovered locality are the changing hydrological regime and seasonal drying up of the small Kubanka River. Local impacts on the C. canescens population caused by economic activity include trampling by cattle grazing in the river valley. The significant in area and numerous population of C. canescens is localized in a nature conservation area, which will ensure its long-term survival and guarantee effective protection regime.
