Mahogany

• 1. Introduction

  ›

  Mahogany is a straight-grained, reddish-brown wood from three tropical tree species in the genus Swietenia, native to the Americas. By 1788, the peak year of eighteenth-century trade, more than 30,000 tons of it were flowing into Britain alone each year. The wood was so prized that it sparked a debate still unresolved today: where does its very name come from? And what drove a single type of timber to reshape entire coastlines, fuel colonial rivalries, and end up at the center of one of the most consequential environmental decisions in the history of the lumber trade?

• 2. A Name With No Clear Origin

  ›

  In 1671 the word mahogany appeared in print for the first time, in John Ogilby's book America, where it described a "curious and rich wood" from Jamaica. But where did that word itself come from? Two competing theories have dominated the debate, and neither has ever fully won.

  Kemp Malone, writing in 1940, proposed that mahogany began as a generic term for "wood" in a native Bahamian language. F. Bruce Lamb rejected that idea, pointing instead to the Yoruba word oganwo, used collectively as m'oganwo, meaning "one which is the tallest or most high." Lamb argued that Yoruba and Igbo people transported to Jamaica as enslaved laborers recognized the local Swietenia trees and applied the same name they used for Khaya trees back in West Africa. From m'oganwo, his theory runs, the word passed into the Portuguese mogano, which first appeared in print as a river name in 1661, and eventually settled into the English mahogany sometime between 1655 and 1670.

  Malone pushed back hard. He found the leap from the Yoruba singular oganwo to the collective m'oganwo linguistically implausible, partly because the Swietenia tree typically grows alone rather than in dense stands. He also noted that the river Lamb cited as evidence for mogano could have been named for any tall tree, since oganwo simply means tall. Lamb, in turn, challenged Malone's methodology and maintained there is no evidence for mahogany as a generic word at all.

  While the linguists debated, botanists were classifying the tree on their own timeline. Carl Linnaeus placed it in the cedar genus in 1759, calling it Cedrela mahagoni. The following year, Nicholas Joseph Jacquin reassigned it to its own genus and named it Swietenia mahagoni, the name that stuck.

• 3. Three Species, One Name

  ›

  Sir George King named the third and most commercially significant species, Swietenia macrophylla, in 1886, after studying specimens planted in the Botanic Gardens in Calcutta, India. Before that, botanists and traders had spent most of the nineteenth century assuming all mahogany was a single species.

  Honduran or big-leaf mahogany, S. macrophylla, grows from Mexico southward all the way to Peru, Bolivia, and the far western edge of Brazil. It is the only genuine mahogany still commercially cultivated today. West Indian or Cuban mahogany, S. mahagoni, once dominated the trade entirely; it is native to southern Florida and the Caribbean but has not been in widespread commercial use since World War II. The third species, Swietenia humilis, is a small, often twisted tree confined to seasonally dry forests along the Pacific coast of Central America, and some botanists consider it merely a variant of S. macrophylla.

  When the three species grow in proximity, they can crossbreed. The hybrid between S. mahagoni and S. macrophylla is now widely planted for timber. Beyond the three official Swietenia species, the Federal Trade Commission permits certain other woods to be sold under the mahogany name in the United States, provided they carry a qualifying prefix. "African Mahogany" covers five species of the genus Khaya. "Philippine Mahogany" covers seven species in the genera Shorea and Parashorea, also known as lauan or meranti. No other wood can legally be sold as mahogany in the American market without one of those qualifiers.

  A cross in the Cathedral at Santo Domingo, bearing the date 1514, is said to be mahogany, one of the earliest known uses of the wood by Europeans. Philip II of Spain apparently used it for the interior joinery of the palace El Escorial, begun in 1584. Even so, the Spanish largely treated caoba, as the Taino people called it, as a strategic resource. It was declared a royal monopoly at Havana in 1622 and reserved primarily for shipbuilding, meaning very little reached Europe.

  The transformation of mahogany into a mass-market luxury began in Britain with the Naval Stores Act 1721, which removed all import duties on timber from British possessions in the Americas. The effect was immediate. Imports into England climbed from 525 tons per year by 1740, to 3,688 tons by 1750, reaching more than 30,000 tons in 1788.

  Until the 1760s, over 90 percent of the mahogany imported into Britain came from Jamaica. Much of it was used by British furniture makers, while the wood used in American colonial furniture came largely from the Bahamas and was often called Providence wood, or madera. The first Honduras mahogany arrived in Kingston, Jamaica, in November 1763, carried by loggers who had been cutting logwood in Belize and the surrounding region and turned to mahogany after the European market for logwood collapsed.

  Hispaniola mahogany, also called "Spanish" or "St Domingo" mahogany, entered the British market in the late 1760s following the Free Port Act 1766, which opened Kingston and other Jamaican ports to foreign vessels for the first time. By the 1790s, Jamaica's own viable mahogany stocks were largely exhausted, and the trade had settled into two main grades: Honduras mahogany, plentiful but rarely of the finest quality, and Hispaniola mahogany, prized for high quality work.

• 5. The Global Spread

  ›

  India was one of the first countries outside the Americas to receive Swietenia plantings, when both S. macrophylla and S. mahagoni were introduced in 1865 using seeds from the West Indies. Bangladesh followed in 1872 with Honduran S. macrophylla, and Indonesia received both species in 1870 from Indian seed stock.

  Fiji received S. macrophylla in 1911, originally as an ornamental species using seeds from Honduras and Belize, and has since become a major mahogany producer in the twenty-first century thanks to a plantation program spanning over fifty years, with harvesting beginning in 2003. The Philippines received multiple plantings of both species between 1907 and 1922, with planting resuming in the late 1980s as part of reforestation efforts.

  The reason the Asian plantations succeeded where native-range replanting failed comes down to a moth larva. Efforts to regenerate mahogany in its original American range were largely undone by the shoot borer Hypsipyla grandella, which attacks young trees. A related species, Hypsipyla robusta, caused equivalent damage to replanting attempts in Africa. Asia and the Pacific had neither pest, which allowed plantation management to progress through the 1990s and 2000s and push global supply of genuine mahogany upward. However, the trees in Asian plantations are still relatively young compared to old-growth trees still being cut in South America, and illegal logging of bigleaf mahogany has continued.

  Mahogany's wood properties are exceptional by almost any measure. Its grain is straight, fine, and even, largely free of the voids and pockets that weaken other timbers. Its reddish-brown color deepens with age and develops a reddish sheen when polished. Its specific density is 0.55, with Cuban mahogany coming in at 660 kg/m3 and Honduras mahogany at 650 kg/m3. The tree's girth historically produced wide boards unavailable from most other species.

  Much of the finest furniture made in the American colonies from the mid-eighteenth century onward was mahogany. It resists rot, making it attractive for boat construction and outdoor decking. As a tonewood, it is used in the backs, sides, and necks of acoustic guitars, electric guitar bodies, and drum shells, valued for producing a deep, warm tone compared to maple, alder, or spruce. Gibson used mahogany for the Les Paul and SG electric guitars, and in the 1930s for banjo necks as well.

  The price of this versatility has been severe. By the end of the nineteenth century, scarcely any part of coastal Central America had been left untouched by logging, with activity extending into Colombia, Venezuela, Peru, and Brazil. Britain alone imported more than 80,000 tons in 1875, a figure never matched again. Peru surpassed Brazil as the world's largest exporter after Brazil banned mahogany exports in 2001, but it is estimated that some 80 to 90 percent of Peruvian mahogany exported to the United States is illegally harvested. The economic cost of that illegal logging in Peru has been placed conservatively at $40-70 million USD annually. In 2000 alone, an estimated 57,000 mahogany trees were harvested to supply the American furniture trade.

• 7. CITES and the Battle to Regulate

  ›

  Swietenia humilis was the first of the three species placed on CITES Appendix II in 1975, which lists species that would face extinction risk without strict trade controls. S. mahagoni followed in 1992, and S. macrophylla was added to Appendix III in 1995 before being moved to the more restrictive Appendix II in 2003. That 2003 listing was a landmark: S. macrophylla was the first high-volume, high-value timber tree ever placed on Appendix II of CITES.

  Beyond the shoot borer damage, replanting in native ranges faced another obstacle. After decades of mismanagement and illegal harvesting, Swietenia trees suffered from genetic loss, which weakened and mutated their seeds. Erosion in native locations meant that in some areas seeds could no longer even be planted. International conservation programs began in earnest after 1992 and 1993, aided by a World Bank report published that year on tropical hardwood marketing strategies.

  In the Philippines, environmentalists have called for an end to new mahogany plantings, arguing that the species causes soil acidification and provides no net benefit to wildlife. Mahogany is the national tree of both the Dominican Republic and Belize. In Belize, a mahogany tree with two woodcutters bearing an axe and a paddle appears on the national coat of arms, beneath the motto Sub umbra floreo: Latin for "under the shade I flourish." That motto, chosen for a country built on the mahogany trade, now reads as something close to a quiet acknowledgment of how much of the modern world grew in mahogany's shadow.
