However, it becomes more extreme towards the interior regions. 12% of the land is covered by forests. 18% of the land is arable out of which 5% is irrigated. The country has Atlas mountain range which not only divides the country into different terrains but also cause a variation in climatic zones. Several different climates like Mediterranean and Maritime Temperate allow different species of oaks, junipers, carpets, Atlantic cedars and many other plants. This leads to the formation of very extensive and rich humid cloud forests. On the other side there is the big Sahara desert. Here, the interesting features are oasis, sand dunes and rocky desert landscapes.
