Entandrophragma angolense

Entandrophragma angolense, commonly known as Tiama or African cedar, is a large forest tree species belonging to the Meliaceae family. It is a highly regarded timber crop in tropical Africa, known for its significant contribution to both the forest economy and the maintenance of dense humid tropical forest ecosystems.

The species is native to tropical Africa, with a natural range extending from Sierra Leone and Guinea in the west through the Congo Basin to Uganda and Angola in the east. It typically thrives in moist, evergreen, or semi-deciduous forests. The tree is an emergent species, often rising high above the forest canopy, reaching heights of up to 50 meters in pristine conditions.

Botanically, the species is characterized by its massive, straight, and cylindrical bole, which often features low buttresses at the base. The leaves are paripinnate and compound, forming a dense crown. The fruit is a woody capsule that splits into five valves when mature, releasing winged seeds which are efficiently dispersed by wind across the forest floor.

In terms of agrotechnics and silviculture, Entandrophragma angolense requires deep, fertile, and well-drained soils to reach its full potential. While it favors tropical climates with consistent moisture, it must be protected from waterlogged soil conditions. Plantation management involves careful canopy manipulation, as saplings are shade-tolerant and require protection from direct sunlight during their early growth stages.

The tree is primarily utilized for its high-quality, durable timber, which is highly sought after for cabinet making, decorative veneer, and high-end joinery. The wood is prized for its attractive reddish-brown color, fine grain, and good working properties. Besides its economic value, the species is actively managed in reforestation efforts to preserve biodiversity and restore degraded tropical habitats.
