In southwest Morocco, you might actually be forgiven for asking daft questions like “do goats grow on trees?”. Everywhere you look, you will find dozens of goats hanging out lazily from the tree tops, munching absentmindedly like overgrown crows.
Goats are skilled climbers and are known to scale steep rock faces and mountains in search of food. The ones in Morocco climb trees for the same reason – food, which is otherwise scarce in this drought-ridden region. The goats are drawn to the fruit of the Argan tree, which ripens in June each year. The Argan grows to 8-10 meters high and live up to 150–200 years. They are thorny, with gnarled trunks, but the goats, who have been climbing these trees for centuries, have learnt to adapt themselves to the task.
The goats native to this region have cloven feet. Each hoof has two toes which can spread out, providing balance and leverage, while the soles of their feet are soft and yielding, helping them to grip the bark. The animals also have two vestigial toes higher up their legs, called dewclaws. These are found on many species including cats and dogs, but the goats’ dewclaws are much firmer and stubbier and help the creatures pull themselves up branches, or lower themselves down sheer cliff faces.
The Argan is endemic to the semi-desert Sous valley of southwestern Morocco and to the Algerian region of Tindouf in the western Mediterranean region. The fruit is also a valuable source of oil, and an important source of economy for the Berber people of Morocco. The fruit, which is about 2–4 cm long, has a very hard nut surrounded by the fleshy part that the goats eat. Inside the nut contains one or two, small, oil-rich seeds. The fruit takes over a year to mature, ripening in June to July of the following year. Until this happens, the goats are kept out of the Argan woodlands, because the animals would often eat the fruit before it’s ripe, as well as the leaves stunting the growth of the trees.
Traditionally, the goats were a part of the oil producing business. The local Berber people would allow the goats to eat the fruit, but the hard nut would pass through the animal’s digestive system unharmed. The goat excrete would then be collected, the seeds removed and grinded or pressed to extract oil, which is used in salad dressing and cosmetics. Removing the soft pulp is the most labor-intensive part of the oil-extraction process which is why the goats were employed. Modern methods, however, have bypassed this stage because a “goaty” smell can sometimes be detected in the oil.
During the past two decades, argan oil has soared in popularity and price to become the world's most expensive oil (about $300/liter). It is sold in Europe and North America where it has become a fashionable product.
Ironically, the argan oil’s popularity has threatened the very survival of this tree. The extra cash acquired from selling the oil has enabled the locals to buy more goats, resulting in more climbing and damage to the trees. Trees are also felled for their wood or to make way for other crops. Through the 1970s and 1980s about 600 hectares of argan forest per annum was lost.

Are the local Berber people made aware that their practice is not sustainable? If yes, are they doing anything about it?
ReplyDeleteAs ingenious as the goat oil refinement system is, if I knew where the oil came from, I probably would not sprinkle it on my salad.
ReplyDeleteI love evolution
ReplyDeleteAccording to Wiki: The best hope for the conservation of the trees may lie in the recent development of a thriving export market for argan oil as a high-value product.
ReplyDeleteThat makes more sense to me.
this article is very good knowledge, I never knew that goats have been blessed with such innovative standard to adapt for living.
ReplyDeleteKudos to the writers and the photographer. Thanks
Really interesting! Loved the pictures of goats in trees.
