Vegetation - Flora

In Poros, just like on the other islands of the Saronic, the condition is obviously better, as far as the natural environment is concerned, comparative to Attica. Almost the entire surface of the island, except the sections of the North- North-east side of it, is covered by pine trees.

On the north- north-east side of the island, there are olive groves and some farms with lemon trees and orange trees. In the area of Fousa, are still cultivated some vineyards, by which the great Fousaetian wine is produced. On the north of Fousa, on the mountains, bushes and brushwood are found, with the most dominant, the oak trees, the lentisks, the bretia and the bearberries, while in the peninsula of Bisti, the venies dominate.

Sfairia is triangular stone palisade that has three sides. The beds of stone are of trachyte and the vegetation is almost non-existing. Nowadays, it has no natural source of water. Its coasts have totally 3.650 m. length and are extended towards three directions. It is volcanic and came from an explosion of the volcano, from which Methana also came, during the pre-historic years.

Fauna

The geologic bedrock (limestone), the physiognomy of the flora and the climatic conditions do not allow the existence at the area o f a big variety of species of land fauna and bird-fauna. The species that are noticed are rabbits, wild bunnies, badgers, mice, hedgehogs, turtles and ferrets. On the opposite Troizinia, there are also wolves, coyotes and foxes.

Also, the emigrating birds that visit the island are the trugoni, the quail, the babbler, the woodcock, the apiarist bird and the fig eater.
