The island vegetation is Mediterranean, rich and varied. Korcula is one of the most forested Adriatic islands, as much as 61% of its surface is covered with woods and macchia thickets. Conifers grow everywhere: Aleppo pine (Pinus halepensis), stone pine (Pinus pinea), Dalmatian black pine (Pinus nigra), cypress (Cypressus), and other species. The island has thick indigenous forests of holm oak (Quercus ilex), wild olive, carob, and bay. Heather, arbutus, prickly juniper, vetch and other plants grow in the low undergrowth called macchia. #$#
