This tree, also known as argania spinosa is endemic to the Sous valley of southwestern Morocco. Nicknamed, “the Tree of Iron”, the argan tree possesses roots that can reach 30 m which allows it to draw water at great depth and to survive in arid and semi-arid regions.

The period between ~700 and 900 CE coincides with the Arabization of Morocco which had an impact on the demographic composition of the country leading to new agricultural habits and, as a result, on the land-use triggering a higher erosion of lowland material by the Souss River. This region is presently subject to severe droughts, desertification and land degradation, and likely facing increased climate variability and socio-economic stress in the future. An Israeli company, named Sivan, has created a special strain of argan trees that are tolerant to the Mediterranean climate and can produce 10 times more nuts than their Moroccan equivalent. In this study, researchers analysed over a 3400-year history of vegetation, climate and fire frequency change to assess the impact on the Argan tree in southern Morocco using pollen, tiny charcoal fragments and sediment records. But how long will the argan tree be endemic? Model simulations show that climate change will likely have a stronger effect resulting in more arid conditions on Morocco than on other North African regions, where agriculture is the main form of land use. Understanding the diverse ways in which our climate may change over time at a regional or local level is critical for a broad range of applications including city design, crop yields and natural disaster planning. 5.For us women, it is known as a “Beauty Champion” for its great applications in cosmetics. Zielhofer, C, Von Suchodoletz, H, Fletcher, WJ. Successful introduction of this species in Argentina depends on the degree of climate similarity in the natural area compared to new areas with agroclimatic suitability.

The southwest of Morocco is considered to be an area of refuge within the Mediterranean region, hosting the endemic tropical Argan tree.
