Mahogany
(Swietenia macrophylla)











    Family: Meliaceae
    Genus: wietenia
    Species: Swietenia macrophylla The three species are poorly defined biologically, in part because they hybridize freely when grown in proximity.
    Common Names: mahogany, Caoba, Atlantic mahogany, Chacalté (Mayan)
    Parts Used: Wood


PLANT DESCRIPTION
Characteristics:
Easily identified in the forest because of its unique canopy and branches; leaves are usually bright and the asymmetric shape of leaflets can be clearly seen through binoculars; erect grayish to reddish fruits located at the tip of branchlets are very conspicuous, measuring more than 10 cm in length. It is a big tree, reaching 50 meters in height with a clean trunk up to 25 meters; adult trees have a 75 - 150-cm diameter at breast height and buttresses may rise to 4 meters. Bark is dark reddish brown with many deep fissures along the trunk

Distribution and ecology: It is found at 0 - 400 m.a.s.l. in subtropical moist forests and subtropical wet forests. It can be seen in the Guatemalan provinces of Petén, Izabal, Quiché, and Alta Verapaz, and also from southern Mexico to the Amazon basin and Peru in tropical forests.

Wood and uses: Wood from this species is considered to be one of the best known in the world and for a long time it has been the standard in assessing all the other species as to furniture manufacture. When freshly cut, its wood has a reddish heart, and it is pink, salmon or yellowish.

Potentially Endangered: Bigleaf mahogany is one of the worlds most valuable timber species, averaging $1300 per cubic meter in the U.S. This high value drives a thriving and largely illegal logging industry in many parts of South America. Loggers will often build roads into virgin forests to extract a single stand or tree of mahogany. This provides access for those logging other timber species in these areas, which ultimately leads to burning any remnants to make way for agriculture and ranching. This cycle has been repeated throughout the Amazon, making mahogany logging a leading driver of deforestation in the region. Such illegal logging and deforestation also contributes significantly to habitat destruction of other rare rainforest species, such as tucans and parrots. Additionally, the US National Academy of Sciences lists the species as vulnerable, and other international experts note its complete disappearance in three-quarters of Central America and commercial extinction in areas of Brazil and Colombia.

To slow this destruction and to avoid the extinction of bigleaf mahogany, Guatemala and Nicaragua proposed listing the species on Convention on International Trade in Endagered Species of Wild Fauna and Flora (CITES) which is the most important international treaty governing trade in threatened and endangered wildlife.. at the twelfth Conference of the Parties to CITES in November 2002. This would require that future trade in mahogany be conducted more sustainably. Despite opposition by Bolivia and Brazil, both major exporters of mahogany, countries voted overwhelmingly in favor of protecting the species.
