摘要:

In southern Tunisia where mean annual rainfall is less than 200 mm, the flora is more and more subject to a high and continuous human pressure for at least the last century.

These trees and shrubs are among the most threatened species of the southern Tunisian flora for several reasons, as excessive use for domestic purposes, and their poor natural and even artificial regeneration.
