Distribution Overview
Avodire is distributed in tropical Africa, from Sierra Leone to the Congo region and Angola, and is most common in the eastern region of Ivory Coast. It is usually found in dense stands in rain forests, alongside lakes and streams.

Product Sources
The ITTO reports that timber from this species is produced regularly but in low quantities and is exported regularly.
The material is exported from the Ivory Coast to the world market in log form. Quantities are low and price is usually in the moderate range. The price of Avodire varies with grade and type of grain in the veneer. Avodire veneer of architectural grade is in the moderate price range.

Avodire exhibits similar machining characteristics to those of the mahoganies since they are in the same botanical family. It is also reported to have almost the same strength properties as English oak (Quercus ), although it is about 15 percent lighter. The wood is slightly better to work with than Primavera. It is rated as medium in crushing and bending strengths, and low in shock resistance and stiffness. Hardness is rated as medium, weight is about average, and it has high density. Timber produced by the species is often mixed and marketed with that ofTurreanthus vignei .
