The Pelion region is host to rare kinds of flora and fauna and threatened habitats that are protected by European Union Directives 92/43 and 79/409.
Because of its importance, Pelion was included in the NATURA 2000 network of the European Union with the code GR 143 0001.
Among its habitat types, those that stand out include the undersea meadows of Posidonia oceanica (priority habitat), the beech and chestnut forests (which are in excellent condition), and the marine caves.
Flora: three species are included in the Greek “Red Book” (Campanula incurva, Lesquereuxia syriaca and Soldanella pelia), while a total of 38 species and subspecies are endemic, rare, threatened, or protected.
Fauna: the survival of certain protected species of birds and insects—such as the European honey buzzard (Pernis apivorus), the booted eagle (Aquila pennata), the white-backed woodpecker (Dendrocopos leucotos), the semi-collared flycatcher (Ficedula semitorquata),and the stag beetle (Lucanus cervus)—depends on maintaining the deciduous forests in good condition.
