Okume wood (also ocume) is native to Central Africa, mainly from countries like Gabon or Equatorial Guinea. At the bottom, it is a soft wood, very regular in appearance thanks to its smooth texture and straight grain, and light brown color.
In these countries, okume wood exports represent between 80% and 90% of wood exports, thus being the main species.
The tree can reach 300 years, 2.5 meters in diameter and up to 60 in height. However, this is not frequent, as the species is constantly exploited. Although it is not considered risky, since in Gabon exists in large numbers, the speed with which the resource is exploited elsewhere is worrying. There are cultures dedicated to the exploitation of this wood in many African countries. However, demand and exports are greater than this production.
Its scientific name is Aucoumea klaineana.
