Goats love to climb the argan trees and eat the fruits. Unfortunately, they damage the tree so it's best to keep them away from it. The old traditional way of harvesting argan oil was to collect the seeds from the goats droppings. Not so common any longer but it's important to know where you buy your argan oil from.
The Argan tree (Argania Spinosa) can only be found in Southwestern Morocco, which makes it precious and rare. The Argan forest is now protected by UNESCO. The Argan trees are sustainable and produce Argan fruit year after year. The local Berber women have created cooperatives where they hand-crack and make the Argan oil.
