Abstract
The paper provides an overview of all freshwater red algae species recorded to date in the territory of Bosnia and Herzegovina. Based on fieldwork and analysis of all available previously published data, it was determined that a total of 15 taxa from eight genera have been recorded to date: Bangia (1), Audoinella (3), Batrachospermum (2), Peludicola (1), Shaethia (1), Lemanea (4), Paralemanea (2) and Hildenbrandia (1). All taxa were found in clear, cold, well-oxygenated water. Bosnia and Herzegovina is very rich in different types of aquatic habitats. More than 100 sites were visited during the field research, but there are still many potential habitats where freshwater red algae can be found, which will be explored in the coming years. This work is the first step toward establishing long-term monitoring and listing of protected and threatened red algae in Bosnia and Herzegovina.
