Challenges of Conservation and Sustainable Management of African Rosewood (Pterocarpus Erinaceus) in West Africa
Chapter Challenges of Conservation and Sustainable Management of African Rosewood (Pterocarpus erinaceus) in West Africa Adjonou Kossi, Houetchegnon Towanou, Rabiou Habou, Segla Kossi Novinyo, Abotsi Komla Elikplim, Johnson Benziwa Nathalie, Alaba Pyoabalo, Ouinsavi Christine A.I. Nougbodé, Quashie Akossiwoa Marie-Luce, Kokutse Adzo Dzifa, Mahamane Ali and Kokou Kouami Abstract Pterocarpus erinaceus is an endemic and threatened plant species in arid and semiarid zones of West Africa and is highly exploited for timber, animal feeding, and various medicinal uses. The species is currently native to the Guinean forest- savannah mosaic ecoregion and reported from Senegal to Cameroon. The values of the main characteristics of the P. erinaceus forest stands (density, average diameter, À average height and average stem height) vary significantly (P < 10 3) from the Guinean zone to the Sahelian zone. It has high technological performance and can be classified as heavy and very hard wood with a density of the order of 0.80 Æ 0.07 g/cm3 and an average hardness of 12 Æ 3.7 g/cm3. The species is the subject of large-scale international traffic between West Africa and Asia, which is by far the greatest threat to the species. The various uses induce repeated mutilation and increase pressures on the species resulting in a significant reduction in its natural populations. In response to this situation, measures are proposed, including large-scale plant production strategies, the definition of minimum felling diameters, policy measures, etc., to meet the restoration needs of natural stands of P. erinaceus and the fight against climate change. Keywords: Pterocarpus erinaceus, socioeconomic services, wood properties, uncontrolled logging, sustainable management, West Africa 1. -
Dalbergia Proposal Guatemala (Rev.2)
CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES I AND II A. Proposal Inclusion of the genus Dalbergia in CITES Appendix II with exception to the species included in Appendix I. The UNEP-WCMC assessed the Dalbergia species of Latin America and concluded: “… all populations of Dalbergia spp. from South and Central America appear to meet the criteria for listing in CITES Appendix II” (UNEP-WCMC, 2015). Including the whole genus in Appendix II will be essential for the control of international trade by eliminating the arduous task of enforcement and customs officers of differentiating between the hundreds of Dalbergia species listed and not listed in CITES. The inclusion will help ensure that legal trade does not become a direct cause of the extinction of these highly threatened species and will help curb illegal trade. Considering that CITES Appendix II must include all species, which although not necessarily now threatened with extinction may become so unless trade in specimens of such species is subject to strict regulation in order to avoid utilization incompatible with their survival, it is important to include the genus Dalbergia in CITES Appendix II. a) Resolution Conf. 9.24, Annex 2 a, Criterion A - ”It is known, or can be inferred or projected, that the regulation of trade in the species is necessary to avoid it becoming eligible for inclusion in Appendix I in the near future”. b) Resolution Conf. 9.24, Annex 2 a, Criterion B - ”It is known, or can be inferred or projected, that regulation of trade in the species is required to ensure that the harvest of specimens from the wild is not reducing the wild population to a level at which its survival might be threatened by continued harvesting or other influences”. -
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607)
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607) by Nancy Ross Preface Since it was published in 1984, Tropical Timbers of the World has proven to be an extremely valuable reference to the properties and uses of tropical woods. It has been particularly valuable for the selection of species for specific products and as a reference for properties information that is important to effective pro- cessing and utilization of several hundred of the most commercially important tropical wood timbers. If a user of the book has only a common or trade name for a species and wishes to know its properties, the user must use the index of common names beginning on page 451. However, most tropical timbers have numerous common or trade names, depending upon the major region or local area of growth; furthermore, different species may be know by the same common name. Herein lies a minor weakness in Tropical Timbers of the World. The index generally contains only the one or two most frequently used common or trade names. If the common name known to the user is not one of those listed in the index, finding the species in the text is impossible other than by searching the book page by page. This process is too laborious to be practical because some species have 20 or more common names. This supplement provides a complete index of common or trade names. This index will prevent a user from erroneously concluding that the book does not contain a specific species because the common name known to the user does not happen to be in the existing index. -

BOX 447, Arusha, Tanzania 3 Mikocheni Agricultural Research Institute, P.O.Box 6226, Dar es Salaam, Tanzania *Corresponding Author. Email: [email protected] Abstract Dalbergia melanoxylon is an economically and ecologically important timber yielding tree species. It is propagated through seeds, but is not successful because of poor seed germination that limits its multiplication. Therefore, the objective of this study was to develop efficient micropropagation protocol for this species. Cotyledonary nodes were used as explants. The highest (85.33%) explants initiated shoots on Murashige and Skoog (MS) medium containing 2.0 mg/l 6-benzyl amino purine (BAP) and 1.0 mg/l -Naphthaleneα acetic acid (NAA) of the culture revealed greatest shoot multiplication (6.12 ± 0.13) from nodal segments. The shoots rooted best (92%) on MS medium containing 1.0 mg/l NAA with 5.89 ± 0.47 roots per microshoot. Plantlets were planted in pots containing sterilized forest soil and sand mixture (1:1) and acclimatized in greenhouse. After four weeks of acclimatization in greenhouse, 84.6 % of plants survived. This protocol could be useful for large-scale multiplication and conservation of this ecologically and economically important multipurpose tree.

Wood Research Effect of Heat Treatment and Wax
WOOD RESEARCH doi.org/10.37763/wr.1336-4561/65.6.963974 65 (6): 2020 963-974 EFFECT OF HEAT TREATMENT AND WAX IMPREGNATION ON DIMENSIONAL STABILITY OF PTEROCARPUS MACROCARPUS WOOD Lin Yang1,2, Tianqi Han1, Yudong Fu1 1Nanjing Forestry University China 2Northeast Forestry University China (Received March 2020) ABSTRACT In order to improve dimensional stability and control deformation, heat treatment (HT) and wax impregnation (WI) were conducted to large size boards (LB) of Pterocarpus macrocarpus and the tangential swelling were compared in various relative humidity (RH) conditions. The results show that the tangential swelling and shrinking of control group and treated group performed differently corresponded to various relative humidity (RH). Comparing with control group, the swelling ratio of HT combined WI group was much less, and followed by 180°C-3h HT group. The maximum swelling ratio decreased by 31% and 29% in humidity chamber and indoor conditions respectively. The swelling ratio was affected by size of samples, LB showed smaller welling ratio than small sample. Wax filled in cell cavities and presented uneven distributions after impregnation. The rate of wood hygroscopicity was reduced after HT combined WI treatment which was an effective method on improvement of wood dimensional stability. KEYWORDS: Pterocarpus macrocarpus, heat treatment, wax impregnation, dimensional stability, modification. INTRODUCTION Pterocarpus macrocarpus mainly grows in Myanmar, Laos and Thailand, belonging to the butterfly-shaped flower Pterocarpus, Rosewood mahogany (Azratul et al. 2017), which is categorized as a red Suanzhimu class in China national standard— “Hongmu” (GB/T18107- 2017). Pterocarpus macrocarpus has straight trunk, branches few and it is excellent wood tree species. -
