GENERAL USES:

  1. Timber: Entandrophragma cylindricum is highly valued for its timber, which is known as Sapele or African mahogany. The wood is durable, moderately heavy, and exhibits a distinctive reddish-brown color with a pronounced grain pattern. It is widely used in furniture making, cabinetry, flooring, veneer, musical instruments, and boatbuilding.

GEOGRAPHIC DISTRIBUTION: Entandrophragma cylindricum is native to tropical regions of West and Central Africa. It is found in countries such as Nigeria, Cameroon, Ghana, Ivory Coast, and Congo.

WHY IS IT GREEN? Entandrophragma cylindricum, like other plants, appears green due to the presence of chlorophyll in its leaves. Chlorophyll is a pigment that captures sunlight and facilitates the process of photosynthesis. It absorbs red and blue light while reflecting green light, giving plants their characteristic green color.

ENVIRONMENTAL IMPACT: Entandrophragma cylindricum has both positive and negative environmental impacts. As a large tree, it provides habitat and shelter for various species, contributes to forest biodiversity, and helps maintain ecosystem balance. However, overexploitation of its timber has led to deforestation and habitat loss in some regions. Sustainable forestry practices and conservation efforts are crucial to ensure the long-term viability of this species.
