Lebanon is known for the highest densities of floral diversity in the Mediterranean

Lebanon is known for the highest densities of floral diversity in the Mediterranean basin which is one of the most biologically-diverse regions in the world. It hosts tree species with critical biogeographical locations (southernmost limit) on the western slopes of Mount Lebanon’s mountain range such as Cedrus libani A. Rich. in the Shouf Biosphere, which is a notable keystone species and flagship plant in the country that has been exploited since the rise of civilization in the Fertile Crescent.
