Source-derived summary

The East Saharan montane xeric woodlands is an ecoregion of central Africa, a number of high mountains in the middle of the huge area of savanna on the edge of the Sahara Desert.

Location and description

The ecoregion covers the higher elevations of the Ennedi Plateau and the Ouaddaï Highlands of eastern Chad and the extinct volcano system Jebel Marra in Darfur, western Sudan. These mountain ranges rise above the semi-desert sahelian Acacia savanna at the southern edge of the Sahara Desert. The ecoregion covers an area of 27,900 square kilometers (10,800 sq mi). The summer rains are irregular, even more so in Chad than on Jebel Marra, which has two crater lakes.

Flora

Plant life includes many species typical of the sahel belt including Ammania gracilis, the grass Panicum laetum, the forb Chrozophora brocchiana and the herbs Farsetia stenoptera, Indigofera senegalensis and Tephrosia gracilipes. One classic element of the natural flora was Laperrine's Olive (Olea europaea laperrinei).

Fauna

Water from mountain streams makes the area an important habitat for wildlife such as a number of threatened antelope species such as addax (Addax nasomaculatus), Dama gazelle (Gazella dama), Dorcas gazelle (Gazella dorcas) and Red-fronted gazelle (Gazella rufifrons). Endemic species include the Arid Thicket Rat (Grammomys aridulus) from Jebel Marra. The mountains are home to birds of both Eurasia and Africa, species include Nubian bustard (Neotis nuba) and Cinereous Vulture (Aegypius monachus).

Editorial summary

“East Saharan montane xeric woodlands” enters the record as desert ecoregion in Africa. Crown Archives preserves that source wording while asking what East, Saharan and montane can confirm, complicate or overturn.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 231-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around East, Saharan and montane.
Editorial analysis

Why this record matters

“East Saharan montane xeric woodlands” is worth following because a concise public description often conceals a longer documentary argument. Here, East, Saharan and montane provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 13, 2024. The linked authority identifier is Q3850748. Authority coordinates are 17.400, 22.576. None of the 2 selected statements returned an explicit reference.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
