Swietenia humilis

It is found in the drier zones of the western Sierra Madre mountain range from Mexico through Guatemala, Belize, Honduras, and El Salvador. The distribution in Guatemala and Honduras bulges eastward from the Pacific Coast nearly to the Atlantic Ocean. In Honduras it also extends from the western Sierra Madre into the abutting northern Nicaraguan cordillera range. The northern half of the Pacific Coast of Costa Rica includes habitat. It is found at altitudes up to 1,200 metres (3,900 ft). Its habitat is both wet and dry deciduous forest, savanna, rough scrub, rocky hillsides and cultivated fields. The species having been over-exploited, surviving trees usually are scattered and isolated individuals. Large specimens are rare.

The multilateral treaty CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) lists S. humilis in Appendix II (all parts and derivatives except seeds). It is also categorized in the IUCN (International Union for Conservation of Nature) Red List of Threatened Species as Vulnerable (Version 2011.2).
