The species diversity of algae-macrophytes in the coastal zone and inland lakes of the Kinburn Spit of the Black Sea within the National Nature Park "Biloberezhzhia Sviatoslava" was studied. Algological samples were collected during the vegetation periods of 2019–2021. As a result of the study, 53 species of macrophyte algae were identified, belonging to 33 genera, 23 families, 17 orders, 7 classes, and 4 divisions. The most diverse were Chlorophyta (42.6%), followed by Rhodophyta (40.7%), and Heterokonthophyta (Phaeophyceae) (13.1%). Charophyta accounted for 3.6%. Among red algae, the dominating families were Ceramiaceae and Rhodomelaceae, while among green algae, they were Cladophoraceae and Ulvaceae. The macrophytobenthos of the Black Sea coast and its Yahorlytska Bay showed the highest similarity of floristic structure. By geographical distribution, the benthic algal communities were dominated by boreal and cosmopolitan groups; by frequency of occurrence— common and rare species; by vegetation duration — annual species; and by tolerance to organic pollution — meso- and oligosaprobes. The relatively high taxonomic diversity of macro algae from various ecotopes, along with the presence of several rare species, indicates that the “Biloberezhzhia Sviatoslava” Park fulfills its important nature conservation function.
