This work results as an in-depth study of mixed cork-oak, by the necessity to profound the knowledge of Moroccan forest ecosystems, particularly in
the Central Plateau. Accordingly, we describe a new association of the cork-oak forest subhumid, thermomediterranean and mesomediterranean, na
med Quercetum rotundifolio-suberis ass. nova and two new subassociations consecutively named Quercetum rotundifolio-suberis chamaeropetosum
humilis subass. nova and Quercetum rotundifolio-suberis cistetosum libanotidis subass. nova. Their floristic and ecologic particularities are exposed.
Key words: BEIS of El Harcha, Central Plateau, cork-oak woodlands, Morocco, phytosociology.
