The Sous region is an area in mid-southern Morocco. Geologically, it is the alluvial basin of the Sous River , separated from the Sahara desert by the Anti-Atlas Mountains. The natural vegetation in the Sous region is savanna dominated by the Argan (Argania spinosa), a local endemic tree found nowhere else; part of the area is now a UNESCO Biosphere Reserve to protect this unique habitat. The tree produces an annual fruit crop, and it is this delicious morsel that attracts legions of local goats who hop up into the branches to pick out the fruit. These memorable rural scenes mostly happen in June when the Argan fruit ripen.
