2.3.4 'Mahogany' trees

Mahogany table circa 1839
Foreign craftsmen (Dutch and French) arrived in Britain following the accession of William of Orange and his wife Mary (the daughter of James II), in 1689. William of Orange was Dutch and hence a great deal of Dutch influences entered into English life. Fine cabinetmaking, walnut and ebony veneers and florals. Legs are turned to trumpet shapes or scrolled and scroll develops into cabriole leg by the end of William's reign in 1702.
William and Mary furniture was graceful and decorative, it had a well-developed sense of display and articulation. There was much use of ornate decorative effects on surfaces such as veneering, parquetry, lacquer, and marquetry, particularly in side tables. This was the beginning of the era of the cabinetmaker and men such as Gerrit Jensen excelled at very fine inlay and marquetry work. Cabinets, as well as writing bureaus and escritoires, gained domed tops, and were set on heavily baroque style stands with doric columns, as were tables.
Chairs were set on turned legs whose stretchers were tied and curved and mirrored the carving decoration of the crest at the back. Upholstered chairs had square back rests and supports separating them from the seats and their upholstering was more ample and comfortable.
Walnut was very much in demand by the immigrant Dutch and French furniture makers of the William and Mary period. Oak was rapidly sliding into country obscurity and mahogany was just making its very first inroads. There was also use of kingwood and amboyna for inlay work and ebony was used for very fine, fancy pieces such as looking glasses and curio cabinets.
The history of mahogany logging is linked inseparably to the history of colonialism. Prized originally by European furniture makers for its dark colour, stability and ability to be carved in scrolls without breaking, mahogany was first targeted shortly after Columbus invaded the New World.

The history of mahogany logging is also a history of deforestation in the Caribbean and Central and South America. The wave of logging that began in the 1500s and has expanded out from the original point of European invasion of the Americas, and continues to this day, is nearly identical to the expansion of the mahogany frontier.
There are numerous species of mahogany and a number of other species of trees called 'mahogany' in trade. Generally, “true” mahoganies are those in the genus Swietenia, the species of which are found throughout the Caribbean and Central and South America. However, species from Africa in the genus Khaya are also considered mahoganies as they are distantly related.

Swietenia
There are four species of Sweitenia in Latin America: Caribbean mahogany (Swietenia mahogani), Honduran or Pacific Coast mahogany (Swietenia humilis), bigleaf or big-leafed mahogany (Swietenia macrophylla) and Venezuelan mahogany (Swietenia candollei). There is much confusion as to their common names, with bigleaf mahogany often being called true mahogany, geniune mahogany, South American mahogany or Honduran mahogany. Local common names include acajou and caoba.

Swietenia mahogani, known as Caribbean, Cuban or true mahogany, is found from the tip of southern Florida and throughout the West Indies. Swietenia humilis, known as Honduran mahogany, is found on the Pacific coastal region of Central America. Both of these species are listed in Appendix I of the Convention on Trade in Endangered Species of Flaura and Fauna, known as CITES. This means that countries trading in these species need to verify that sources are legal and sustainable and all trade must come with paperwork showing origin.

The majority of the trade in mahogany is currently bigleaf, S. macrophylla. This species is now listed on Appendix II of CITES after decades of lobbying by environmental groups and counter-lobbying by industry groups.

Bigleaf ranges from the north of the State of Veracruz to Yucatan in Mexico, along the north Atlantic slope of Central America to Venezuela and Brazil. It also occurs in Colombia, Peru, and Bolivia at elevations of up to 4900 feet (1500 m), and on Cape Verde Islands.

Bigleaf mahogany is an emergent tree, growing to heights of over 150 feet and diameters of 6 feet. It is a sun-loving tree, rapidly growing in clearing and then reaching heights that take its crown above the canopy.

The US is the largest importer of mahogany by volume and by dollar value. US demand helped to decimate the populations of Caribbean and Honduran mahogany. Later, big-leafed mahogany was targeted, first mostly in Central America. US mahogany imports from around 1900 to 1960 were almost entirely from Belize and Mexico3. Mahogany in these countries has been reduced to third-rotation trees that are still being cut, often illegally, before they even mature.

US imports from 1960 to 2002 were largely from Brazil, Bolivia and Peru. Since Bolivia's change in forestry law, exports of mahogany have fallen. From 1995 to 1998, U.S. imports from Bolivia decreased by two-thirds, while U.S. imports from Peru surged nearly fourfold4. Further, with Brazil's recent crackdown on illegal mahogany logging (after decades of calls by environmental organizations) and Bolivia's shift to mostly certified logging operations, since 2002, Peru has become the largest exporter to the US. Much of the logging there is illegal, as most of it was in Brazil and much of it in Bolivia.

In Peru, mahogany's range has shrunk by 50%, and, within a decade, a further 28% will be logged out.5

African Mahogany

Typically Khaya ivorensis, but also other species in the Khaya genus are sold as African mahogany, including K. anthothecaK. grandifoliola, and K. senegalensis.

Khayas are grand trees, reaching heights of 110 to 140 feet with trunk diameters of as much as 6 feet.

Khayas are found from the Ivory Coast to Gabon and Cabinda, and are primarily found in the Ivory Coast, Ghana, and Nigeria. The largest exporters to the US are Ivory Coast and Ghana.

Sapele (Entandrophragma cylindricum) is sometimes sold as African mahogany and ranges through
  Cameroon and  Democratic Republic of Congo (Zaire).

These species are heavily targeted by illegal loggers in Africa and as well, many of these countries allow for overlogging that is not sustainable. IUCN lists these species as vulnerable in much of their range, due to overlogging.
