The Probable Ancient Regional Ecology
North Africa enjoyed a fertile climate during the subpluvial era; what is now the Sahara supported a savanna type of ecosystem, with elephant, giraffe, and other grassland and woodland animals now typical of the Sahel region south of the desert. Historian and Africanist Roland Oliver has described the scene as follows:
the highlands of the central Sahara beyond the Libyan desert,... in the great massifs of the Tibesti and the Hoggar, the mountaintops, today bare rock, were covered at this period with forests of oak and walnut, lime, alder and elm. The lower slopes, together with those of the supporting bastions — the Tassili and the Acacus to the north, Ennedi and Air to the south — carried olive, juniper and Aleppo pine. In the valleys, perennially flowing rivers teemed with fish and were bordered by seed-bearing grasslands.

Famous quotes containing the words probable, ancient and/or ecology:
“I have very lately read the Prince of Abyssinia [Samuel Johnson’s Rasselas]MI am almost equally charmed and shocked at it—the style, the sentiments are inimitable—but the subject is dreadful—and, handled as it is by Dr. Johnson, might make any young, perhaps old, person tremble—O heavens! how dreadful, how terrible it is to be told by a man of his genius and knowledge, in so affectingly probable a manner, that true, real happiness is ever unattainable in this world!”
—Frances Burney (1752–1840)

—Herbert Hoover (1874–1964)
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
