Geographical Cross-section View of the Island
Ugljan lies parallel to the near mainland, it extends in the northwest-southeast direction, 24 km in length and 3-4 km in width. The total surface area of the island is 52 km2, and the length of the coastline is somewhat more than 70 km. The island relief is exceptionally mountainous. It is made up of two parallel mountain chains whose height is around 100 to 300 m above sea-level. The mountainous high plains fill the central part of the island and it is covered by a whole net of dry walls creating a maze of trekking trails, a result of thousands of years of land clearing in order to gain more surface area for olive groves. The eastern side of the island descends gently towards the sea, and all the localities have taken shelter in its coves. The opposite side is mainly wild, steep and uninhabited.
The island of Ugljan has all the characteristics of Mediterranean climate with an average annual temperature of 16°, around 800 mm of rainfall and 2600 hours of sun annually.
Flora and Fauna
The vegetation of the island is characterized by Mediterranean flora. The typical island vegetation of black oak, pine trees, cypresses and high bushes is, on most of the island, substituted by Mediterranean cultivation dominated by olive and fig trees. Nothing is more characteristic for the island scenery of Ugljan than the thousands of olive trees. The archeological findings in Muline confirm that the olive processing and oil production on the island are more than 2000 years old.
The olive groves function as an eco system, attracting many songbirds with their micro world. The ecologically clean submarine world of the island of Ugljan, with some ten small islands belonging to it, are the habitat of numerous types of fish, seashells, and corals, a real place of discovery for divers.
