The Ecoregion of the Sahara Desert


Most Palm trees are located in Morocco, Africa in the Sahara Desert. The palm trees line along the valleys and riverbeds of southern Morocco and the binding roots of the palm tree help prevent soil erosion from intense desert winds. There are around 5 million palm trees in the country of Morocco, Africa in which is northwest part of the Sahara Desert.

Here is a video of somebody climbing up a palm tree.
Rivers, isolated oases, and saline lakes are among the few water bodies in the Sahara Desert. Less than 100 mm of rain falls each year in much of  the eco-region, which extends from the Northwestern Egypt and also along Libya, Algeria, Mali and Mauritania, and ends at Morocco. The climate varies across the eco-region in Northwestern Sahara as there is low rainfall occurrence. This is the reason why there isn’t nearly as much water and plants in Sahara.

I believe Chotts and Wadis are the two forms that create the eco-region of the Sahara Desert. The Desert is made up of 70% of Regs. Plants, moisture and rock forms all together make up for just 10% of the desert. The Sahara Desert is made up of more rock material and less plants. Chotts are depressions that are filled with water during the winter seasons and is evaporated establishing salt instead during the spring and summer seasons.

Wadis are water resources that come from rain and are found in Hammada's and/or mountains. This is what helps establish the plants of the Sahara Desert. Other forms of trees such as, doum and date palm trees, Acacia trees, fig trees and olive trees are created due to rainfall precipitation from Wadis. Below is a video containing a large portion of what I covered in this post along with previous blogs.
