Abstract: In the Mediterranean geographical area, temporary pools often form naturally on natural depressions. Annually, the amount and duration of impoundment of these pools depends on the amount of precipitation and some of the melting snow. Often, the biodiversity of these types of wetlands is high. The vegetation of temporary pools is composed of various floristic groups often arranged in concentric bunches around their centers. The structure of these groupings may vary according to the climatic zone of situation of the pond. Thus, we contribute to determining the composition and organization of the vegetation of the temporary pools of the western part of the Mamora forest which is located in north-west Morocco. The results showed that 56 species were identified. These species have been grouped into 19 botanical families and 40 genera. Likewise, this vegetation is distributed over four concentric belts around the center of the biotope and different in their degree of humidity and the duration of their flooded phase. Plant groups whose systematic structure and species recovery index are still the same from one belt to another. The hygrological and pedological requirements of the species are the main cause of this difference.
