ABSTRACT
“Biodiversity” (or biological diversity) is considered in Morocco neither as a formally individualized development sector nor as a clearly defined environmental theme, but rather as a concept and a support/ecological and environmental constituted by all the biological, ecosystem resources, Genetic, landscape and abiotic conditions governing these resources. The International Convention on Biological Diversity (CBD, Rio de Janeiro, 1992) clearly defined its content as: “The variability of living organisms from all sources, including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part. This includes diversity within and between species and ecosystems.”
