The genetic structure and genetic diversity of Mexican populations of Swietenia macrophylla were evaluated. In Mexico, this neotropical tree reaches its northernmost distribution limit. The relationship between genetic diversity and geographic position (longitude, latitude) of four populations...

To determine the regeneration dynamics and growth rate of mahogany in the natural tropical forests of Quintana Roo, oral histories were used to find essentially even-aged stands that had become established naturally between 2 and 75 years ago, after a hurricane, forest fires, or mechanical distru...

Mahogany has become the flagship species in debates about the feasibility of sustainable forest management in the tropics. Communities that own and control approximately 500,000 ha of permanent forest estate in Quintana Roo, Mexico, and an NGO that manages over 100,000 ha in neighboring Belize, h...

To mimic catastropic disturbances which have favored the establishment of natural stands rich in mahogany (Swietenia macrophylla), two 5000 square meter clearings were established in each locations using each of three treatments: complete felling; slash and burn; machine-clearing with uprooted al...

In 2002, mahogany (Swietenia macrophylla) was listed on Appendix II of CITES (the Convention on International Trade in Endangered Species). This requires that all producing countries define and implement sustainable production systems for mahogany, the most commercially important neotropical timb...

Four years of annual diameter measurements of 75 big-leaf mahogany (Swietenia macrophylla King) trees in natural forests in northwestern Belize were analyzed to determine growth rates. Mean diameter increment among the sample trees exceeded 1 cm y-1, with slightly higher growth rates among trees ...

The most important timber species in Neotropics, mahogany (Swietenia macrophylla) is still harvested from natural forests. The difficulty of ensuring its regeneration in logged-over forests was a primary reason for listing this species in CITES appendix II in 2003, requiring producer countries to...

The annual diameter measurements four years of 75 big-leaf mahogany (Swietenia macrophylla King) trees in natural forests in northwestern Belize were analyzed to determine growth rates. Mean diameter increment exceeded 1 cm year-1, with slightly higher growth rates in trees > 50 cm dbh. Inter-ind...

Although mahogany, the most commercially important timber tree in Neotropical forests, is widely acknowledged to be threatened by unsustainable logging which does not provide for its regeneration, its fruiting dynamics are poorly understood. During each of six successive years, the authors measur...

Honduras or bigleaf mahogany (Swietenia macrophylla King) is the most commercially important timber species in the Neotropics, but it often does not regenerate successfully after harvesting. Effective methods are needed to sustain mahogany yields by increasing regeneration. This study evaluates t...
