Ecology

A. guatemalensis is listed as threatened by the IUCN due to timber exploitation and loss of habitat. It characteristically grows in deep fertile soils, which are desirable for agriculture by local inhabitants. It was reported as being a common tree up until the 1940s. Large populations may still remain in Honduras, but data is currently deficient. Some evidence suggests that the remaining stands in Guatemala

 in Guatemala is said to harbor the largest and best-conserved stands, though these are also threatened by illegal logging. As a result of its status it has become illegal to harvest in some countries where it is native and it is listed in CITES Appendix I, making its international trade illegal. The Central American And Mexico Coniferous Resources Cooperative (CAMCORE) has also begun programmes to protect the tree in the wild.
