As elevations and rainfall increase in the maritime ranges of the north, the vegetation becomes denser. Aloes are common, and on the higher plateau areas of the Ogo are woodlands. At a few places above 1,500 meters, the remnants of juniper forests (protected by the state) and areas of Euphorbia candelabrum (a chandelier-type spiny plant) occur. In the more arid highlands of the northeast, Boswellia and Commiphora trees are sources, respectively, of the frankincense and myrrh for which Somalia has been known since ancient times.
