Rosewood
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. True rosewoods Genuine rosewoods belong to the genus '' Dalbergia''. The pre-eminent rosewood appreciated in the Western world is the wood of '' Dalbergia nigra''. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name ''rosewood''. Another classic rosewood comes from '' Dalbergia latifolia'', known as (East) Indian rosewood or ''sonokeling'' (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood ('' Dalbergia maritima''), known as ''bois ...

Illegal Logging In Madagascar
Illegal logging has been a problem in Madagascar for decades and is perpetuated by extreme poverty and government Political corruption, corruption. Often taking the form of high grading, selective logging, the trade has been driven by high international demand for expensive, fine-grained lumber such as rosewood and ebony. Historically, logging and exporting in Madagascar have been regulated by the Politics of Madagascar, Malagasy government, although the logging of rare hardwoods was explicitly banned from protected areas in 2000. Since then, government orders and memos have intermittently alternated between permitting and banning exports of precious woods. The most commonly cited reason for permitting exports is to salvage valuable wood from cyclone damage, although this reasoning has come under heavy scrutiny. This oscillating availability of Malagasy rosewood and other precious woods has created a market of rising and falling prices, allowing traders or "timber barons" to s ...

Cocobolo
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 relative density of over 1.0, it will sink in water. The sapwood (not often used) is a creamy yellow with a sharp boundary between it and the heartwood. Provenance Cocobolo is yielded by two to four closely related species of the genus ''Dalbergia'', of which the best known is ''Dalbergia retusa'', a fair-sized tree, reported to reach in height and in diameter; it probably is the species contributing most of the wood in the trade. Because of the high value of the timber, the trees yielding it have been heavily exploited, so they have become rare outside of national parks, reserves, and plantations. Only small amou ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant community, plant cropping or crop, formed by the collection of individual Crown (botany), plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, Arboreal, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, Ecological resilience, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants. Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted ...
