Tibesti-Jebel Uweinat montane xeric woodlands

The Tibesti-Jebel Uweinat montane xeric woodlands ecoregion, in the deserts and xeric shrublands biome, is located in the eastern Sahara. The woodlands ecoregion occupy two separate highland regions, covering portions of northern Chad, southwestern Egypt, southern Libya, and northwestern Sudan.

The ecoregion covers 82,200 square kilometers (31,700 sq mi) in the volcanic Tibesti Mountains of Chad and Libya, and 1932-m peak of Jebel Uweinat on the border of Egypt, Libya, and Sudan. The climate is arid and subtropical, but can reach 0°C at the highest altitudes during the winter. Rainfall is irregular but more regular than the surrounding desert and may of the lower wadis are watered by rain which falls higher up.

The Tibesti (and to a lesser extent the Jebel Uweinat massif) foster higher, more regular rainfall and cooler temperatures than the surrounding Sahara. This supports woodlands and shrublands of date palm (Phoenix dactylifera), acacias, Saharan Myrtle (Myrtus nivellei), oleander (Nerium oleander), tamarix, and several endemic and rare plant species, such as Ficus teloukat. The northern slopes are humid enough to support wetland species such as Juncus maritimus, Typha australis, Scirpus holoschoenus, Phragmites australis and Equisetum ramosissimum.
