Project Meliaceae
Genetic Resources: Genetic Variation
This web site is a continually evolving and ongoing
project. Its purpose is to improve communication among all groups
and individuals that are involved with these species. We need
your help! If you have a link, information to share, or are interested
in authoring a section of the site, please send email to: mftf@mahoganyforthefuture.org

Improvement needs. There is a need for documentation of natural
variation of the three species of mahogany. For S, macrophylla
there are large geographic gaps separating different populations.
Differences in wood properties have been observed on different sites.
The validity of separate macrophylla-humilis needs study. There
is variation in S. mahagoni in Cuba and the Dominican Republic.
Phenotype variations include wood quality.

Resulting from the overall projects:
Journal publications:
Swietenia macrophylla -Costa Rican populations cannot be cut
and Nicaragua is evaluating management of the species. CITES proposal
review recommended that species be included in Appendix II based on
state of Central American and Mexican populations (C. Navarro).
