The foliar biomass produced by green oak coppices in two experimental plantations located in the Middle Atlas and the El Ayat forest massif in Eastern Morocco was assessed using dendrometric and weighted data. Based on a stratified random sample, regression models were developed in order to estimate the biomass. The dimensional method is the analysis method used within the framework of this study. The results showed that: - the circumference at 1.30 m above the ground constitutes the best parameter for the assessment of dry biomass; - foliar production varies from one region to another, reaching 2.47 tons per ha at Bab Bou Idir, which corresponds to 247 UF per ha, 1.95 ton per ha at Dayat Aoua, which is equivalent to 195 UF per ha, 1,97 ton per ha in the Aït Hatem forest, which is equivalent to 197 UF per ha, and 0.778 tons per ha at the El Ayat forest massif, which corresponds to 77.8 UF per ha.
