On the island of Lesvos there are 3 protected areas Natura 2000.
Bay of Kalloni
The first area is the Bay of Kalloni, which is very important for the bird migration. Many rare species of birds stop here during their migration (those who follow the eastern runway of Greece). Many species that belong to Annex 1 to Council Directive 409/79/EEC live here.
Bay of Geras
The second area is the Bay of Geras, the wetland Ntipi – Larsos and Mount Olympus. One can also meet here a lot of birds that belong to Annex 1 of Directive 409/79 / EEC.
Western Peninsula of Lesvos
The third area is the western peninsula of the island that includes the Petrified Forest in Sigri. Here there are some of the birds that are rare in Europe, such as the Krüper’s Nuthatch, the Cinereous Bunting, the Rüppell’s Warbler, etc. The Petrified Forest is located in the northwest end of the island, near the village of Sigri. It is a bare treeless area, within which scattered petrified tree trunks or parts of trunks are distinguished, coming from a forest that existed there millions of years ago. The petrified species of plants that are found here belong to the flora of Cenozoic Era and they are various species of gymnosperms and angiosperms. So far they have identified more than forty species. Some of the petrified species are plants that prefer mild temperatures and from the perspective of plant geography, they are subtropical with related genera in the forests of Southeast Asia, for example a large number of species of the Lauraceae genus, (Laurus, Cinnamomum etc.) Another group includes the plants that prefer continental climate and belong to the genera Alnus, Carpinus, Populus, Quercus, Pinus, Sequoia etc.
The study of multiple samples indicates that most of the trunks belong to the conifer trees of Taxodiaceae family and probably to the Sequoia genus.
The petrified trees do not only exist in the northwest side of the island. You can find them in all the west part, as well as in the south side of the island. Petrified trees are also found at Rogkada in Ampeliko and in the area of Akrasi on the south side of Mount Olympus.
