Following the devastating droughts in the 70s and 80s in the Sahel region south of the Sahara desert, vegetation has now recovered. What surprised the researchers is that although it is now raining more and has become greener, it is particularly the more drought resistant species that thrive instead of the tree and shrub vegetation that has long been characteristic of the area. The conclusion is that not only rain but also agriculture and human utilization of trees, bushes and land affect the plants recovering.
