Dalbergia retusa Family: Leguminosae Cocobolo Other Common Names: Granadillo (Mexico, Guatemala), Funera (El Salvador), Palo negro (Honduras), Nambar (Nicaragua, Costa Rica), Cocobolo, Cocobolo prieto (Panama). Distribution: Pacific regions of Central America and extending from Panama to southwestern Mexico. Of limited occurrence, usually in the drier uplands. The Tree: A small to medium-sized tree 45 to 60 ft high with trunk diameters of 20 to 24 in.; usually of poor form. The Wood: General Characteristics: Somewhat variable in color when freshly sawn but heartwood usually becoming a deep rich orange red with black striping or mottling on exposure Texture fine; grain straight to interlocked; oily; without distinctive taste, odor slightly pungent and fragrant when worked. Fine dust may cause dermatitis. Weight: Basic specific gravity (ovendry weight/green volume) 0.80 to 0.98; air- dry density 62 to 76 pcf. Mechanical Properties: No data available, but is denser and stronger than Brazilian rosewood (see D. nigra). Drying and Shrinkage: Reported to have excellent drying properties, free of surface and end checking. A kiln schedule similar to T1-B1 has been suggested. Shrinkage is usually low; high stability in use. Very low moisture absorption. Working Properties: Reported to have excellent machining characteristics; natural oils give the wood a good polish, but make it unsuitable for gluing. Fine dust may produce rash resembling ivy poisoning. Durability: Durability is high, has very high resistance to marine borer attack. Preservation: No data available. Uses: Highly favored in the cutlery trade for handles, inlay work, brush backs, musical and scientific instruments, jewelry boxes, chessmen, and other specialty items.

INTRODUCTION (II) • The species belongs to the family Fabaceae – Papilionoideae. • Pterocarpus erinaceus is a medium- sized, generally deciduous tree 12-15 m tall, bole often of poor form. INTRODUCTION (III) • The bark surface is finely scaly fissured, brown- blackish with thin inner bark. It produces red sap when cut. INTRODUCTION (IV) • Traditionally, the species is used for the production of high quality charcoal and for building construction especially by local people. Rosewood Occurrence in Ghana (I) • The species occurs mostly in the forest savannah transitional zone and parts of the northern savannah woodland ecological zone. • Found in open forest and wooded savannah. Rosewood Occurrence in Ghana (II) • There are ten regions in Ghana. • Rosewood occurs in six of these regions, namely, Asha nti, Brong Ahafo, Northern, Upp er East, Upper West and Volta regions. HARVESTING REGULATIONS • Generally, Timber resource allocation & harvesting is based on Timber Resources Management Act, Act 547 of 1998 and the related Regulation LI 1649 of 1999. • For Rosewood, the issuance of permit to contractors prior to exploitation and monitoring exploitation once the permit has been issued have been the main regulatory mechanism since the surge in its export.

While a number of tree species had been brought under CITES regulation over the previous decades1, COP-17 saw a marked expansion of CITES timber species listings. The Parties at COP-17 listed the entire Dalbergia genus (some 250 species, including many of the most prized rosewoods), Pterocarpus erinaceous (kosso, a highly-exploited rosewood species from West Africa) and three Guibourtia species (bubinga, another African rosewood) to CITES Appendix II.2 The new listings entered into force on January 2, 2017.
