it dominated the market. In 1907 the total of mahogany from all sources imported into Europe was 159,830 tons, of which 121,743 tons were from West Africa. By this time mahogany from Cuba, Haiti and other West Indian sources had become increasingly difficult to obtain in commercial sizes, and by the late 20th century Central American and even South American mahogany was heading in a similar direction. In 1975 S. humilis was placed on CITES Appendix II (a list of species that would be in danger of extinction without strict regulation) followed by S. mahagoni in 1992. The most abundant species, S. macrophylla, was placed on Appendix III in 1995 and moved to Appendix II in 2003. Uses Mahogany has a straight, fine, and even grain, and is relatively free of voids and pockets. Its reddish-brown color darkens over time, and displays a reddish sheen when polished. It has excellent workability, and is very durable. Historically, the tree's girth allowed for wide boards from traditional mahogany species. These properties make it a favorable wood for crafting cabinets and furniture. Much of the first-quality furniture made in the American colonies from the mid 18th century was made of mahogany, when the wood first became available to American craftsmen. Mahogany is still widely used for fine furniture; however, the rarity of Cuban mahogany, the over-harvesting of Honduras and Brazilian mahogany, and the protests by indigenous peoples and environmental organizations from the 1980s into the 2000s, have diminished their use. Recent mahogany production from Mexico and Fiji has a lighter color and density than South American production from the early 20th century. Mahogany also resists wood rot, making it attractive in boat construction and outdoor decking. It is a tonewood, often used for musical instruments, particularly the backs, sides and necks of acoustic guitars, electric guitar bodies, and drum shells because of its ability to produce a very deep, warm tone compared to other commonly used woods, such as maple, alder, ash (Fraxinus) or spruce. Guitars featuring mahogany in their construction include select Martin Guitars such as the D-18, select Taylor Guitars, select Gibson Guitars such as the Les Paul, SG and J45 and select Hagström guitars. In the 1930s Gibson used the wood to make banjo necks as well, the RB, TB and PB style 3s and RB, TB and PB style 75s were most commonly fitted with mahogany necks. Mahogany as
