The cork oak forest, a defining feature of the Mediterranean region, is renowned for its cork production, a commodity of substantial industrial significance. This study aims to elucidate the structure of cork oak stands in Theniet-El-Had National Park and to characterize the cork they produce. To achieve this, 40 temporary plots were established, facilitating the sampling of 390 cork oak trees across two cantons (Sidi Abdoun and Ourten). Analysis of the distribution of various dendrometric measurements reveals that these cork oak forests form stands with an irregular structure. The growth in circumference and height varies significantly with concave topography, which allows for better water accumulation, and moderately inclined terrain, which provides improved drainage. Additionally, the characterization of cork growth from the sampling units (60 calas) reveals an average increase of 2.58 mm/year. The results of the cumulative growth study show that approximately 48% of the samples reached a thickness of 27 mm after 12 years, a satisfactory period considered as the rotation for the cork oak forest of Theniet-El-Had. Furthermore, the shape of the average cork growth curve is a regressive polynomial type, indicating a regular decrease and reflecting high-quality cork. The highest growth rates are recorded during the first three years, exceeding 3 mm/year. Beyond this period, the average growth rate falls below 2 mm, reaching 1.5 mm at the end of the eleventh year of growth. This study provides foresters with restoration, regeneration methods, and cork exploitation management tools.
