The tree is a relic of the Earth's Tertiary Period, which ended about 1.6 million years ago, and it grows in only a few other places in the world. It is tenacious, withering and fruitless during extended droughts, and it lives as long as 200 years. So there was alarm that the Argania spinosa, as the tree is properly called, was headed for extinction, along with its precious goat-related oil. (cite:wikipedia)
So if you're ever in Morroco and you see a woman run up to a tree and start beating it silly with a huge long stick... she's either a) knocking out the Argan nuts, or b) knocking out the goats.
