The region is known for the endemic argan tree (which has become a symbol of Souss) as well as for being the capital of the Shilha Berber ethnic group.
Vegetable production, shared between very large farms and small producers, contributes to the economic development of the region.
The Souss plain produces 40% of Moroccan citrus fruits, and 60% of the production of early vegetables.
