The eastern part of the island, where there is the peninsula of Kalamos, has been subject to “Natura 2000”. The quality of the area is due to the fact that the peninsula is naturally protected, because the cliffs, cliffs and lack of roads make it difficult to access. It has great aesthetic value (especially the Kalamos peninsula) and archaeological interest (especially the Monastiri site) while there are many unexplored caves.
The island is also of particular interest for the bird fauna, which uses the area as a migration station. The Ornithological Society is one of the important areas for the protection of birds in Greece. Its flora is rich in common and endemic species (the latter are of great interest, as most of them are rare and endemic to the Aegean).
