Environmental Profile
The environmental status of this species within its geographical boundaries has not been officially determined. The geographical range of Cedrela is throughout Latin America, from Mexico to Argentina, except Chile. The trees prefer rich, well-drained humid soils, but may also be found growing on drier hillsides
Heartwood Color
The heartwood is pink to pale pink brown or reddish brown when freshly cut. The wood darkens upon exposure to a dark reddish brown, sometimes with a purplish tinge. Resin marks may be present in the wood
