CHARACTERISTICS OF TEN TROPICAL HARDWOODS FROM CERTIFIED FORESTS IN BOLIVIA PART I WEATHERING CHARACTERISTICS AND DIMENSIONAL CHANGE R. Sam Williams Supervisory Research Chemist Regis Miller Botanist and John Gangstad Technician USDA Forest Service Forest Products Laboratory1 Madison, WI 53705-2398 (Received July 2000) ABSTRACT Ten tropical hardwoods from Bolivia were evaluated for weathering performance (erosion rate, dimensional stability, warping, surface checking, and splitting). The wood species were Amburana crarensis (roble), Anudenanthera macrocarpa (curupau), Aspidosperma cylindrocarpon Cjichituriqui), Astronium urundeuva (cuchi), Caesalpinia cf. pluviosa (momoqui), Diplotropis purpurea (sucupira), Guihourriu chodatiuna (sirari), Phyllostylon rhamnoides (cuta), Schinopsis cf. quebracho-colorudo (soto), and Tabeb~liuspp. (lapacho group) (tajibo or ipe). Eucalyptus marginatu Cjarrah) from Australia and Tectonu grandis (teak), both naturally grown from Burma and plantation-grown from Central America, were included in the study for comparison. The dimensional change for the species from Bolivia, commensurate with a change in relative humidity (RH) from 30% to 90%, varied from about 1.6% and 2.0% (radial and tangential directions) for Arnburunu cer~ren.risto 2.2% and 4.1% (radial and tangential) for Anadenanthera macrocarpu. The dimensional change for teak was 1.3% and 2.5% (radial and tangential) for the same change in relative humidity. None of the Bolivian species was completely free of warp or surface checks; however, Anadenanthera macrocarpu, Aspidosperma cy- lindrocurpon, and Schinopsis cf. quebracho-colorado performed almost as well as teak. The erosion rate of several of the wood species was considerably slower than that of teak, and there was little correlation between wood density and erosion rate. Part 2 of this report will include information on the decay resistance (natural durability) of these species. -
African Mahogany Wood Defects Detected by Ultrasound Waves
General Technical Report FPL-GTR-239 • Proceedings: 19th International Nondestructive Testing and Evaluation of Wood Symposium African mahogany wood defects detected by ultrasound waves Tamara Suely Filgueira Amorim França Department of Sustainable Bioproducts, Mississippi State University, Starkville, Mississippi, United States, [email protected] Frederico Jose Nistal França Department of Sustainable Bioproducts, Mississippi State University, Starkville, Mississippi, United States, [email protected] Robert John Ross U.S. Forest Service, Forest Product Laboratory, Madison, Wisconsin, USA, [email protected] Xiping Wang U.S. Forest Service, Forest Product Laboratory, Madison, Wisconsin, USA, [email protected] Marina Donaria Chaves Arantes Departamento de Ciências Florestais e da Madeira, Universidade Federal do Espírito Santo, Jerônimo Monteira, Espírito Santo, Brasil, [email protected] Roy Daniel Seale Department of Sustainable Bioproducts, Mississippi State University, Starkville, Mississippi, United States, [email protected] Abstract This study aims to investigate the potential of ultrasound wave to detect defects in 19 years old of two species of African mahogany planted in Brazil. Were used five 76 x 5 x 5 cm samples from each species with different types of defects, and were conditioned to 12% moisture content. The samples were scanned with ultrasound wave in longitudinal direction and every 2,54 cm in radial and tangential directions along the samples. It was possible to identify end split and pin knots in Khaya ivorensis and reaction wood in Khaya senegalensis wood. Beetle galleries did not affect wave velocities in Khaya senegalensis wood. Grain angle had a large effect in ultrasound velocities in radial and tangential directions. Khaya senegalensis exhibit lower longitudinal velocities related to larger amount of interlocked grain in this species. -

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. -

Dimensional Stability of Nine Tropical Hardwoods from Cameroon
Journal of Tropical Forest Science 22(4): 389–396 (2010) Shukla SR & Kamdem DP DIMENSIONAL STABILITY OF NINE TROPICAL HARDWOODS FROM CAMEROON SR Shukla* & DP Kamdem** Laboratory of Wood Science and Technology, Department of Forestry, 126 Natural Resources Building, Michigan State University, East Lansing MI 48824, USA Received September 2009 SHUKLA SR & KAMDEM DP. 2010. Dimensional stability of nine tropical hardwoods from Cameroon. This study investigated the rate of swelling and dimensional stability of nine tropical hardwood species from Cameroon, namely, ayous (Triplochiton scleroxylon), bilinga (Nauclea diderrichii), bubinga (Guibourtia tessmannii), iroko (Chlorophora excelsa), makore (Mimusops heckelii), moabi (Baillonella toxisperma), movingui (Distemonanthus benthamianus), teak (Tectona grandis) and zingana (Microberlinia brazzavillensis). Continuous swelling of wood specimens immersed in water at room temperature for up to a maximum of 48 hours were monitored using linear voltage displacement transducers (LVDTs). The amount of water uptake as function of immersion duration was measured and correlated with wood porosity. Among the species used in this study, teak showed the lowest swelling rate, therefore, the more dimensionally stable property. Ayous, iroko and movingui were relatively more dimensionally stable than bubinga, makore and moabi. The swelling rate in the tangential direction was much higher than the radial. Bubinga, bilinga and zingana exhibited higher radial swelling rates compared with iroko, teak and makore. Similarly, higher tangential swelling rates were obtained for bubinga and movingui in comparison with teak, makore and moabi. The calculated ratios of the tangential to radial swelling rates also known as the anisotropy of the species used in this study were within the normal range and in agreement with published data. -
