Crynodeb
Pollen and magnetic mineralogical analyses of sediment cores from lakes in the Middle Atlas region of Morocco provide evidence for vegetational disturbance, almost certainly anthropogenic, since about 5000 BP. Localized periodic clearances of pine are recorded at Dayat Iffir before a major episode of pine clearance and soil erosion at about 2000 BP. Catchment disturbance at this and two other sites intensified about 1500 years ago, as arable farming incresed in a predominantly pastoral economy. Because evergreen oak resprouts after cutting or burning, it has become the dominant forest tree in much of the region. -from Authors
