Distribution
Brazil (Amapá,
Amazonas, Pará), Colombia, Ecuador, French Guiana, Guyana, Peru,
Suriname, Venezuela
Habitat
A species
of tropical, lowland to submontane, non-seasonal, rainforest. It occurs
on clay soils, developing well in forest clearings (Varty, 1996). The species
is also recorded from areas of mountain savannah forest up to 1280m.
Population
Status and Trends
Populations
throughout the species range have seriously declined because of rosewood
oil extraction. Substantial wild stands are believed to exist still in areas
which are unlikely to be exploited, but where exploitation has occurred
the population is devoid of mature trees and significant signs of regeneration
are absent (Coppen, 1995). The whole tree and its roots are destroyed in
the extraction process, trees of all sizes being harvested indiscriminately
(Varty, 1996). The sole producer at present is Brazil, although the species
was wiped out through exploitation over large areas in French Guiana between
1910 and 1930. Harvesting incurs high costs and is taking place in more
and more remote locations concentrated around Amazon tributaries, principally
in Amazonas and Pará states (Coppen, 1995). Mobile distillation factories
have moved deep into the forest (Varty, 1996). Levels of exploitation have
significantly declined with increased use of synthetic oils (Coppen, 1995).
The species is included in lists of threatened plants in Colobia, Brazil
and Suriname (Calderon, 1997; IBAMA, 1992; Werkhoven, 1997).
Ecology
Early pioneer,
light demanding (Varty, 1996)
Role of species
in the Ecosystem
The few fruit
crops produced are sought by parakeets (Varty, 1996).
Threats
Commercial
overexploitation, poor regeneration, clear-felling/logging of the habitat
(Varty, 1996).
Utilisation
The essential
oil is extracted from the wood. The leaves and roots are also fragrant.
Rosewood oil contains high concentrations of linalool, which can be transformed
into a number of derivatives for the flavour and fragrances industry. Rosewood
oil has for a long time been used in the preparation of more expensive perfumes
and at one time in fragrant soaps. Synthetic linalool and more cheaply harvested
natural sources of linalool are now more commonly used than Rosewood oil.
(Coppen, 1995). The timber is also of some commercial value in furniture-making,
turnery, boat or canoe building, millwork, flooring, plywood, veneer and
the making of agricultural implements and tool handles (Flynn, 1994, Varty,
1996).
Trade
At the height
of international interest in rosewood oil in the 1960s, Brazil alone exported
500 tonnes pa. The world market is now stable at about 100 tonnes (Coppen,
1995). Fluctuations in supplies are caused by changes in rainfall levels,
which affect access to harvesting sites. Although Peru, Colombia and the
Guianas have all produced rosewood oil for the international market, Brazil
is now the only producer. The chief importer is U.S.A. followed by Switzerland,
France and other EC countries (Coppen, 1995).

category
EN A1+2d according

Conservation
Measures
The species
is included in the official list of threatened Brazilian plants compiled
by IBAMA.
Forest Management
and Silviculture
The establishment
of plantations has not been greatly successful and continues at a small
scale (Varty, 1996). Silvicultural studies have been carried out by several
Brazilian institutions and are continued by the Faculdade de Ciências
Agrárias do Pará (FCAP) with assistance from the U.K. institutions,
NRI, OFI and ITE.
