Environmental Profile

Rare
Data source is World Conservation Monitoring Center
Considered vulnerable in its natural habitat because its numbers are threatened by serious adverse factors throughout its range. However, the species likely exists today in relatively large numbers.

Distribution Overview
The species occurs throughout tropical America, from the West Indies and southern Mexico southward to Chile. It is also widely planted from Coquimbo to Valparaiso and Santiago in Chile.

Trength properties are lower than those of European beech (Fagus sylvatica ), especially in hardness and shock resistance. It is moderately hard and resistant to wearing and marring. It is heavy, and high in density. The bark of the tree is reported to yield tanning, and the grain is similar to that of Guarea spp.
