Profiles of Tree Species: The Americas 195 Pterogyne nitens  Leguminosae amendoim bravo, cocal, guiraró, madeira nova, palo coca, tipa colorado Distribution Argentina (Chaco, Corrientes, Formosa, Jujuy, Misiones, Salta, Tucuman), Bolivia, Brazil, Paraguay Habitat The species occurs in dry deciduous forest, caatinga, transition between caatinga and mata de cipó, disturbed deciduous woodland, usually on calcareous soils in areas where there is a well defined dry season. Population Status and Trends The species distribution is contained within an area extending from northern Argentina into Brazil, Paraguay and Boliva. The habitat is unprotected and under decline because of logging, encroaching agriculture and pastoralism (Prado, 1996).  In Bolivia the species represents one of several species, native to the semi-decidous forests of eastern Santa Cruz, which are experiencing increased logging pressure (Killeen, 1997). The demand for the wood, especially for industrial use, has resulted in the species becoming increasingly rare throughout its natural range. The species is included in the databook of endangered species by the FAO (FAO, 1986). Role of species in the Ecosystem Threats Overexploitation, extensive agriculture, pastoralism/ranching Utilisation In Argentina the wood is considered to be of excellent quality and in high demand (Prado, 1996).  The wood is exported from Paraguay and used to make veneer, high-quality furniture, turnery, flooring and plywood. IUCN Conservation category LR/nt according to Prado, D. Conservation Measures Forest Management and Silviculture An average height of 9.02m and DBH of 10.71cm after 14 years growth is recorded from trials in São Paulo.
