The paper provides an overview of the existing knowledge on biodiversity of the whole Vjosa catchment. Besides major gaps in knowledge, the Vjosa catchment is one of the richest in Albania, sheltering a high diversity of habitats and species, most of them of international significance. A variety of protected areas is connected by the River Vjosa and its tributaries and serve as important ecological corridor.Around 150 species of the already known flora and fauna species are listed in the Appendices of the Bern Convention. More than 15 priority habitat types of European interest have been identified (Habitat directive NATURA 2000), as well as 7 habitat priority types (EUNIS, IPA) of high floristic value.Many habitats of the Vjosa area are included in the Directive 92/42/EEC adopted in May 1992: the woody riparian vegetation along river floodplains, with the dominant species Platanus orientalis, Populus alba, Salix spp., Alnus glutinosa, Fraxinus angustifolia, Quercus robur, and Ulmus minor; moreover, chasmophytic vegetation is documented in the area,; coastal sandy dunes with Ammophila arenaria and other rare plant species; The Vjosa Delta-Narta wetland area is mentioned as the second most important site for birds in Albania, with about 80 species recorded. The area is known as the main wintering site for many water bird species including the Greater Flamingo (Phoenicopterus roseus) and Audouini's Gull (Ichthyaetus audouinii). The Dalmatian Pelican (Pelecanus crispus) frequently occurs in the Vjosa Delta zone. Therefore, a special attention must be paid to future hydropower development plans. Conservation actions must address threats to water quantity and quality over wide areas upstream of threatened habitats and species. Based on the presented data the floodplains of the Vjosa River from Tepelena to Mifoli are considered as a potential protected area, specifically a proposed tiverscape National Park.
