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 Anegre Birdseye Maple Black Walnut
African Mahogany African Mahogany (Khaya) is a genus of seven species of trees in the mahogany family Meliaceae, native to tropical Africa and Madagascar. All species become big trees 30-35 m tall, rarely 45 m, with a trunk over 1 m trunk diameter, often buttressed at the base. The leaves are pinnate, with 4-6 pairs of leaflets, the terminal leaflet absent; each leaflet is 10-15 cm long abruptly rounded toward the apex but often with an acuminate tip. The leaves can be either deciduous or evergreen depending on the species. The flowers are produced in loose inflorescences, each flower small, with four or five yellowish petals and ten stamens. The timber of Khaya is called African mahogany, the only timber widely accepted as mahogany besides that of the true mahogany, of the genus Swietenia. Khaya senegalensis, also known as the African dry zone mahogany is also used for its non timber parts. In West Africa, Fulani herdsmen prune the tree during the dry season to feed cattle. Anegre Anegre is milled from the Tawa tree (Beilschmiedia tawa) is a New Zealand broadleaf tree common in the central parts of the country. Tawa is often the dominant canopy species in lowland forests in the North Island and north east of the South Island, Individual specimens may grow up to 30 meters or more in height with trunks up to 1.2 meters in diameter, and they have smooth dark bark. The word "tawa" is the Maori name for the tree. One of the few hardwood trees in the country with good timber, the wood of this tree can be used for attractive and resilient floor boarding. -

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. -
