Biviere Lake (1,278m asl)
Situated within the Municipality of Cesarò and covering a surface area of about 18 hectares, Biviere Lake is the most important high-mountain wetland in Sicily for its great naturalistic value and its particular vegetable and animal population. The very rich flora is influenced by the periodical variations of the water level, leading to a horizontal zonation of the vegetation, which can be divided into six strips, according to the various dominating species. Moreover, the presence of water in a mountain area covered with beech woodlands represents a privileged reference point for the life of several aquatic bird species, as well as for the stopover of migratory birds. A natural phenomenon which is worth a mention: during the summer, the water of the lake turns red because of the blooming of a micro algae called Euglena sanguinea.
