The island of Korcula belongs to the group of islands of middle Dalmatia. The island is known as one of the most wooded islands of Mediterranean (61% of its area covered in forest and underbush). The vegetation is rich and various. From the bioclimatic point of view it belongs to the mediterranean vegetational region inside the framework of the mediterranean littoral zone, in the southern part stenomediterranean and eumediterranean zone in the north. Inside the boundaries of island belongs to the group of 94 botanically significant areas in the Republic of Croatia. It has a number of protected objects of natural values: a special botanical reservation of forests Kocje, a significant landscape of the small island of Badija, two forest-parks on the island of Osjak near Vela Luka and a town-park Hober in the town of Korcula, four monuments of gardenarchitecture (alley of cypress in the town of Korcula, a 450-yearsold cypress in Cara, Foretic park in the town of Korcula and Vela Spila (Big cave) in Vela Luka) and botanical monuments of nature Cesmina in Klokovina, Zrnovo. The most significant forrest plant on the island is holm oak (Quercus ilex L.). Next to he holm oak, the are also allepo pine (Pinus halepensis Mill.), pinaster (Pinus pinater Aiton), dalmatical black pine (Pinus nigra Arnold ssp. Dalmatica (Vis) Franco), pine (Pinus pinea L.), cypress (Cupressus sempervirens L.) and oleaster (Olea europea L. var Sylvestris Brot.). The degradation of forests, especially exploitaton of holm oak (shipbuilding etc.) has contributed the degradation of the vegetation in the stage of underbush. Nevertheless, lately, after supplying the house holds with electric energy and gas, forrests are less used as firewood, which contrinuted to its succession toward climazonal forms.
