Abstract

The AA. studied soil and vegetation response to grazing removal along a steep climatic aridity gradient on the southern slopes of the High Atlas Mountains, Morocco. Data were collected on 4 altitudinal levels (semidesert, sagebrush steppe, woodsteppe and Oromediterranean shrubland), and for 3 grazing treatments (grazed, 1-year and 7-year exclosures). Grazing removal led to site-specific, functionally different pathways of rangeland recovery. It is concluded that correlations between biotic and abiotic recovery processes have to be interpreted carefully, as they may not necessarily be functionally connected. Moreover, the performance of perennial plants is, if interpreted together with abiotic parameters, a useful indicator for distinguishing functionally different pathways of pasture degradation and restoration in drylands
