英文摘要	Human pressure on North African ad pastures is causing soil degradation and rarefaction of perennial grasses. Artificial reintroduction of rarefied species can be an alternative in these areas, where spontaneous regeneration may be too slow. We have evaluated the ecological needs and performance of two perennial grasses with high grazing interest. Tropical Cenchrus ciliaris L. is a C4 that concentrates production during the warmest periods, and may be of particular interest in relatively wet years. Stipa lagascae Roem. & Shultes, is a C3 grass that may thrive under relatively cold conditions. Seeding mixes of these complementary species may contribute to rehabilitate grazing areas where the seed bank has been depleted. Soil degradation, and the reduction in the period when water is available during the summer, partly explain rarefaction of tropical species (as C. ciliaris) and gradual dominance of Mediterranean species (as S. lagascae) in northern Sahara arid pastures.
