Dalbergia melanoxylon (African blackwood, grenadilla, or mpingo) in french Granadille d'Afrique is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea, to southern regions of Tanzania to Mozambique and south to the north-eastern parts of South Africa. The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments,[3] sculptures vinyago in Swahili language and fine furnitures. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates.[3]
African blackwood is a small tree, reaching 4–15 m tall, with grey bark and spiny shoots. The leaves are deciduous in the dry season, alternate, 6–22cm long, pinnately compound, with 6–9 alternately arranged leaflets. The flowers are white and produced in dense clusters. The fruit is a pod 3–7cm long, containing one to two seeds. It is often cited as one of the most expensive woods in the world.
Uses
African blackwood
The dense, lustrous wood ranges in colour from reddish to pure black. It is generally cut into small billets or logs with its sharply demarcated bright yellow-white sapwood left on to assist in the slow drying so as to prevent cracks developing. Good quality "A" grade African blackwood commands high prices on the commercial timber market. The timber is used mainly because of its machinability, density, dimensional stability, and moisture repellence. Those properties are particularly valued when used in woodwind instruments, principally clarinets, oboes, transverse flutes, piccolos, recorders, Highland pipes, and Northumbrian pipes.[4][unreliable source?] The Deering Banjo Company uses blackwood ("grenadilla") to construct the tone ring in its John Hartford-model banjo because it weighs less than brass or bronze tone rings, and that the wood "plays in" (improves in tone) with use. Furniture makers from ancient Egypt on have valued this timber. A story states that it has even been used as ballast in trading ships and that some enterprising Northumbrian pipe makers used old discarded blackwood ballast to great effect. The German knife companies Wüsthof, Böker and J. A. Henckels sell knives with blackwood handles due to the wood's moisture repellent qualities.
Due to overuse, the mpingo tree is severely threatened in Kenya and is needing attention in Tanzania and Mozambique. The trees are being harvested at an unsustainable rate, partly because of illegal smuggling of the wood into Kenya, but also because the tree takes upwards of 60 years to mature.
African blackwood is no longer regarded as ebony, a name now reserved for a limited number of timbers yielded by the genus Diospyros; these are more of a matte appearance and are more brittle.
Other names by which the tree is known include babanus and grenadilla, which appear as loanwords in various local English dialects.
Conservation
There are multiple organisations involved in the conservation of African blackwood: the Mpingo Conservation & Development Initiative, the African Blackwood Conservation Project, and Daraja Music Initiative (formerly Clarinets for Conservation).
The Mpingo Conservation & Development Initiative (MCDI, formerly the Mpingo Conservation Project) is involved in research, awareness raising and practical conservation of African blackwood. Conservation of mpingo and its natural habitat can be achieved by ensuring that local people living in mpingo harvesting areas receive a fair share of the revenue created, thus providing them with an incentive to manage the habitat in an environmentally friendly manner. In order to achieve this, the MCDI is helping communities to get Forest Stewardship Certification.[7]
The African blackwood Conservation Project works around Mount Kilimanjaro replanting African blackwood trees, and in conservation education. It also works with adult and women's groups in the promotion of environmentally sound land uses.[8]
Daraja Music Initiative (formerly Clarinets for Conservation) is a U.S.-based non-profit that aims to raise awareness and promote conservation of mpingo through music education in Tanzania. Students participate in an interdisciplinary program during the summer months that raises awareness of the value of mpingo through musical performances, classroom instruction, and tree plantings at local secondary and primary schools.[9]
Small growers in Naples, Florida have been successful in growing African blackwood there. Growth habit in Florida yields taller, larger trees, and the rich soil combined with ample nutrients and long growing season yields timber of superior quality at more sustainable rates.[10][11]

Ebony is a dense black/brown hardwood, coming from several species in the genus Diospyros, which also includes the persimmon tree. A few Diospyros species, such as macassar and mun ebony, are dense enough to sink in water. Ebony is finely textured and has a mirror finish when polished, making it valuable as an ornamental wood. It is often cited as one of the most expensive woods in the world.
Dalbergia is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic Dalbergia clade : the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and Southern Asia.
Cocobolo is a tropical hardwood of Central American trees belonging to the genus Dalbergia. Only the heartwood of cocobolo is used; it is usually orange or reddish-brown, often with darker irregular traces weaving through the wood. The heartwood changes color after being cut and can be polished to a lustrous, glassy finish. Being quite dense and sometimes having a specific gravity of over 1.0, it will sink in water. The sapwood is a creamy yellow with a sharp boundary between it and the heartwood.
Colophospermum mopane, commonly called mopane, mopani, balsam tree, butterfly tree, or turpentine tree, is a tree in the legume family (Fabaceae), that grows in hot, dry, low-lying areas, 200 to 1,150 metres in elevation, in the far northern parts of Southern Africa. The tree only occurs in Africa and is the only species in genus Colophospermum. Its distinctive butterfly-shaped (bifoliate) leaf and thin seed pod make it easy to identify. In terms of human use it is, together with camel thorn and leadwood, one of the three regionally important firewood trees.
The Makonde are an ethnic group in southeast Tanzania, northern Mozambique, and Kenya. The Makonde developed their culture on the Mueda Plateau in Mozambique. At present they live throughout Tanzania and Mozambique, and have a small presence in Kenya. The Makonde population in Tanzania was estimated in 2001 to be 1,140,000, and the 1997 census in Mozambique put the Makonde population in that country at 233,358, for an estimated total of 1,373,358. The ethnic group is roughly divided by the Ruvuma River; members of the group in Tanzania are referred to as the Makonde, and those in Mozambique as the Maconde. The two groups have developed separate languages over time but share a common origin and culture.
Rosewood is any of a number of richly hued hardwoods, often brownish with darker veining, but found in other colours. It is hard, tough, strong, and dense. True rosewoods come from trees of the genus Dalbergia, but other woods are often called rosewood. Rosewood takes a high polish and is used for luxury furniture-making, flooring, musical instruments, and turnery.
Acacia melanoxylon, commonly known as the Australian blackwood, is an Acacia species native to south-eastern Australia. The species is also known as blackwood, hickory, mudgerabah, Tasmanian blackwood, or blackwood acacia. The tree belongs to the Plurinerves section of Acacia and is one of the most wide-ranging tree species in eastern Australia and is quite variable mostly in the size and shape of the phyllodes.
Tonewood refers to specific wood varieties used for woodwind or acoustic stringed instruments. The word implies that certain species exhibit qualities that enhance acoustic properties of the instruments, but other properties of the wood such as aesthetics and availability have always been considered in the selection of wood for musical instruments. According to Mottola's Cyclopedic Dictionary of Lutherie Terms, tonewood is:
Wood that is used to make stringed musical instruments. The term is often used to indicate wood species that are suitable for stringed musical instruments and, by exclusion, those that are not. But the list of species generally considered to be tonewoods changes constantly and has changed constantly throughout history.
Triplochiton scleroxylon is a tree of the genus Triplochiton of the family Malvaceae. The timber is known by the common names African whitewood, abachi, obeche, wawa, ayous and sambawawa. The tree is the official state tree of Ekiti State, Nigeria.
Pterocarpus santalinus, with the common names red sanders, red saunders, Yerra Chandanam, Chenchandanam, red sandalwood, Rakta Chandana, and rakto chandon, is a species of Pterocarpus endemic to the southern Eastern Ghats mountain range of South India. This tree is valued for the rich red colour of its wood, and in recent years there has been a marked uptick in the use of red sandalwood as a component of incense, especially in the west. The tree is not to be confused with the aromatic Santalum sandalwood trees that grow natively in Southern India.
The Eastern miombo woodlands (AT0706) are an ecoregion of grassland and woodland in northern Mozambique, southern Tanzania, and southeastern Malawi.
Dalbergia sissoo, known commonly as North Indian rosewood or shisham, is a fast-growing, hardy, deciduous rosewood tree native to the Indian subcontinent and southern Iran. D. sissoo is a large, crooked tree with long, leathery leaves and whitish or pink flowers.
Dalbergia cochinchinensis, the Thailand rosewood, Siamese rosewood, or tracwood, is a species of legume in the family Fabaceae.
Dalbergia monticola is a species of flowering plant in the legume family Fabaceae. It is endemic to Madagascar. It occurs at higher elevation, which gave the species its name.
Aniba rosaeodora, also known as pau-rosa, is a species of Magnoliid tree in the family Lauraceae. Often confused as rosewood, the plant doesn't grow on any tree of the genus Dalbergia. It grows in parts of the tropical rainforest of South America. It is an endangered species that is exploited due to its essential oil.
Khaya anthotheca, with the common name East African mahogany, is a large tree species in the Meliaceae family, native to tropical Africa.
Dalbergia retusa is a plant species in the familyFabaceae . It is found in Pacific regions of Central America, ranging from Panama to southwestern Mexico. It produces the cocobolo wood. It is a fair-sized tree, reported to reach 20–25 m in height. This is probably the species contributing most of the wood in the trade. Because of the wood's great beauty and high value, the trees yielding this wood have been heavily exploited and are now rare outside national parks, reserves, and plantations.
