Forests are most abundant in the high mountains. One of the natural resources of Taiwan is camphor laurel, from which a great deal of camphor is produced. One-quarter of the total area in Taiwan is arable and fully cultivated. Sloping areas and dry riverbeds are also under cultivation, as are the tidal lands in the west. The most important crop is rice, which is grown on about 1,000,000 acres.
