You’;ve seen goats climb rocks, houses, cliffs or even this dam in Italy。

But have you ever seen goats climb trees? In Morrocco, this is a very common occurrence。 You see, in most parts of the world where you’;ll find goats, their food is usually right under their hoofs。 In *** around the Atlas Mountains, though, grazing pastures are patchy —; here and there。 So, goats have learned to make the best of anything they could get their adorable hoofs and snouts on, even if that means being perched high up in the trees。

This is not only nice for goats but for the trees themselves too。 According to a recent study in the journal Frontiers in Ecology and the Environment by Spanish researchers who wanted to learn whether domesticated goats benefit argan trees (Argania spinosa)。 

Goats in Southern Morrocco will often climb 30-foot-trees in search for food, in this case, acorn-sized argan seeds。 Even as much as three-quarters of their time is spent in the argan trees during the autumn days when vegetation is scarce。 The team wanted to know if the goats help in any way with seed dispersal。

It’;s well established that many animals spread the seed of various trees and plants by excreting seeds。 This is how all sorts of plant species end up on islands, for instance, after some bird pooped them out even after hundreds of miles。 The argan seed, however, is way too big and shouldn’;t make it intact out of a goat’;s digestive tract。

But precisely because the seeds are so large, they can be a nuisance for the goat。  Instead, the researchers chronicled the goats as they spit the seeds out。 Like cows and other ruminants, a goat has multiple stomachs。 So, what a Moroccan goat does is it will regurgitate the argan seeds from the first stomach and chew on it some more。 During this process, the goats will often spit out some of the argan seeds, sometimes days after first ingesting them。 Some seeds are spit very far from the parent tree too, the team fo***。
