The species most characteristic of the subregion III and of the more xerophytic zones of the subregion III (IV) is 'Argania spinosa' (Schmid). It is difficult to separate the two suborders of vegetation 'Argania' and 'Tetraclinis' which are very similar. For this reason we refer to both of them in a mixed form, as if there existed the suborder 'Argania-Tetraclinis'.
The existing scarce groves of Pinus halepensis in the region supply timbers of the type which has been just described. Timbers of this type attain prices per foot higher than timbers of larger diameters and of better quality in other more wooded regions of Spain. For this reason this species has been used more extensively; similarly in the sandy and coastal zones P. pinea finds considerable utilization. P. halepensis has shown a great-colonising capacity in the entire arid zone. The dissemination of this species is very intense and natural regeneration takes place if grazing pressure and forest fires fail to eradicate the young seedlings.
