Channel connects the lake with the Ionian Sea. Lake Bufi lies about above the Adriatic in the southeast of Lake Butrint, with a total surface area of . Its excessives waters are then discharged into the southern Lake Butrint through a former channel. Biodiversity Flora Due to its diverse geological and hydrological conditions and the mosaic distribution of various types of habitats, the location of the park is also one of the main reasons for the great variety of animals and plants. The park falls phytogeographically within the Illyrian deciduous forests terrestrial ecoregion of the Palearctic Mediterranean forests, woodlands, and scrub. The availability of water in forms of rivers, lakes and wetlands, influenced by the configuration of the terrain, has a great impact on the biodiversity of this area. The vertebrate flora of the park consists of more than 800 up to 900 species, which constitute 27% of the total number of species in Albania. The shallow coastal lagoons are rocky with extensive mussel beds and the water depth is higher than in other areas. They are covered with dense grasses of phragmites and typha latifolia. There are also underwater meadows dominated by zostera noltei and ruppia cirrhosa. Within the archaeological site and southern and eastern slopes of Sotira, Evergreen forests occupy's most of the area. Moreover, it is vertically divided into three distinct vegetation zones. The upper tree level is covered by holly oak and bay laurel, which prevail over the other plants including field elm, narrow-leafed ash and valonia oak. The scrubby level is represented with elmleaf blackberry, common hawthorn, evergreen rose, common ivy and italian leather flower. Moreover, the herbal level is dominated among other by wild asparagus, hedge bedstraw, lesser celandine and purple loosestrife. Posidonia oceanica is mostly distributed along the littoral sea bottom, from the Stillo Cap to Cuka Channel, while cymodocea nodosa and zostera noltei are widely found along the mouth of Pavllo River. Along the cliffs, the salinity and rocky terrain have caused the decreased or poor the floristic composition. They are composed of species such as crithmum, elymus pycnanthus and golden samphire. Fauna The park contains a diverse assemblage of fauna with over 400 species distributed across the park's habitats and ecosystems. At least 39 species of mammals, 246 species of birds, 25 species of reptiles, 10 species of amphibia and 105 species of fish are known to occur within the park's
