Argan oil

Where Does Argan Oil Come From?

Argan oil comes from the argan tree, a species that grows almost exclusively in southwestern Morocco's Souss-Massa region, part of a UNESCO-designated biosphere reserve.

Where does argan oil come from?

Argan oil comes from the kernels of the argan tree (Argania spinosa), a species that grows natively almost nowhere except southwestern Morocco. Its core range is the Souss-Massa region, a strip of semi-arid land between the Atlas Mountains and the Atlantic coast, extending in pockets toward Essaouira. This isn’t a loosely applied geographic label — it’s closer to a botanical fact.

Why the argan tree grows where it grows

The argan tree is adapted to a specific set of harsh conditions: long dry seasons, poor soil, and high heat. Its deep, extensive root system lets it draw water other plants can’t reach, which is exactly what allows it to survive in a landscape too arid for most tree species. That same adaptation is why attempts to grow it commercially elsewhere have had limited success — the tree isn’t just associated with this part of Morocco, it’s genuinely suited to conditions found reliably in only a few places on earth.

Individual argan trees can live for well over a century, growing slowly into the gnarled, wide-canopied shape often pictured in photos of the region — sometimes with goats climbing into the lower branches to browse the fruit, a genuinely common sight in the Souss-Massa countryside.

The Arganeraie Biosphere Reserve

In 1998, UNESCO designated the argan forest of southwestern Morocco as the Arganeraie Biosphere Reserve, one of the largest biosphere reserves in the Mediterranean region. That designation reflects two things: the ecological significance of the argan forest itself, and the traditional human activity — harvesting, cracking, pressing — that has coexisted with it for generations without depleting it, at least under sustainable management practices.

A biosphere reserve isn’t a strict nature preserve where human activity is excluded; it’s a recognition that the forest and the people who work within it are part of the same system. Argan oil production is a central part of that system.

The tree’s ecological role

Beyond producing oil, the argan tree does real ecological work in a region where that matters:

  • Its root system stabilizes soil that would otherwise be prone to erosion in a semi-arid climate.
  • It helps limit desertification by anchoring ground cover in an area bordering the Sahara’s influence.
  • It supports local agriculture and grazing, since goats and other livestock feed on the fruit’s pulp and the tree provides shade in an otherwise exposed landscape.

This is part of why sustained, sensible harvesting of argan fruit — rather than clear-cutting or over-farming — has long-term stakes beyond the oil itself. Trees that are stripped or damaged rather than harvested carefully don’t just affect a single season’s yield; because the argan tree grows and matures slowly, a damaged or lost tree isn’t quickly replaced, which is part of why the traditional harvesting rhythm — waiting for fruit to fall rather than aggressively picking it early — has persisted for generations rather than being replaced by faster methods.

The Souss-Massa region beyond the tree itself

The Souss-Massa area isn’t a single town or forest patch — it’s a broader region stretching inland from the Atlantic coast near Agadir toward the foothills of the Anti-Atlas mountains, encompassing a mix of small agricultural towns, cooperative workshops, and the argan woodland itself. Agadir functions as something of a regional hub for the area, and it’s common for argan oil sold elsewhere in Morocco, or exported abroad, to trace back through this region at some point in its supply chain. If you’re traveling in the area, the tree’s presence is hard to miss — it shows up along roadsides, in fields shared with other crops, and in the goat-in-tree photographs that have become a familiar shorthand for the region.

Why the growing region shapes the product

Because the tree’s range is so narrow, the entire supply chain for authentic argan oil runs through this one part of Morocco. There isn’t a parallel argan oil industry based on trees grown somewhere else — when you see “Moroccan argan oil,” the geography in the name is doing real, verifiable work, not just brand positioning. That’s also why the region shows up repeatedly in any serious explanation of the product, from what argan oil actually is to how it’s pressed and processed.

Frequently asked questions

Does the argan tree grow anywhere outside Morocco?

A very small amount of experimental cultivation exists elsewhere, but the argan tree's natural, commercially significant range is almost entirely limited to southwestern Morocco.

Why was the argan forest given UNESCO status?

UNESCO designated the Arganeraie as a Biosphere Reserve in 1998 in recognition of the argan forest's ecological importance and its role in the region's traditional way of life.

Does the argan tree only grow in one part of Morocco?

Its core range is the Souss-Massa area between the Atlas Mountains and the Atlantic coast, with additional pockets extending toward Essaouira, but this remains a relatively narrow band of the country.
