Lophira

Lophira is a genus of flowering plants in the family Ochnaceae. It comprises several species of large trees native to tropical Africa. The best known is Lophira alata, commonly called azobe or ironwood, which is widespread in tropical West and Central Africa.

Distribution and habitat: Lophira species occur in tropical forests of West and Central Africa, often in lowland rainforests and gallery forests. They are typically tall canopy or emergent trees adapted to humid forest environments.

Uses and timber: Lophira alata yields one of the densest and most durable hardwoods in tropical Africa. The heartwood is very heavy and resistant to decay and termites, making it highly valued for heavy construction, marine timbers, bridge timbers, flooring, and other demanding applications. The timber is slow-growing and requires careful management to ensure sustainable supplies.

Other species: The genus includes several additional African species, though L. alata remains the most widely used for timber and the best known internationally.

Ecology and conservation: Like many tropical hardwoods, Lophira species face pressures from logging and habitat loss. Sustainable harvesting, forest management, and certification programs are important to maintain populations and ensure a steady timber supply.
