Vegetation on the islands is very sparse maquis. There have been 200 known varieties of Mediterranean plants, but they have degenerated. The most common plant is a tough variety of grass, but there are many scented and medicinal herbs: sage, feather grass and Xeranthemum, giving a fragrant spring, and during the year providing the best forage for bees. Olive trees account for about 80% of the land under cultivation, followed by vineyards, figs, orchards and vegetable gardens. It is thought that the Kornati islands were once covered with forests of Mediterranean holm oaks, Quercus ilex, but as open fires demanded a great deal of wood, the forests were slowly destroyed; the sole remnant is round the bay of Tela??ica.[6]
