Identification of the timbers of Southeast Asia and the Western Pacific

Abstract

To say it briefly, this is a marvellous book. It describes in depth and richly illustrates the wood structure of some 180 trade timbers belonging to approximately 60 families. This edition in the English language finally allows access for non-Japanese scientists, wood engineers and applicants of wood to the lifetime work of Ken Ogata, one of the foremost wood anatomists of our time. Contrary to gloomy predictions that by the year 2000 world timber trade would be largely restricted to plantation-grown pines and eucalypts and products manufactured thereof, the diversity of tropical timbers shipped to the main importing countries, such as China, Japan and EU countries, has actually increased. This is a constant challenge for those involved in wood identification. Representatives of wood industry and trade are the traditional and still the most important customers for this service. But on the other hand, also archaeologists, architects, paleobotanists, and, more recently, agencies responsible for monitoring and controlling trade with protected plants and activities concerning illegal logging are also seeking help and advice from wood anatomists responsible for timber identification. And this is what this book addresses.From A (Alangiaceae) to V (Verbenaceae), each hardwood timber description gives a brief explanation of the botanical and trade nomenclature and the geographical distribution of a trade timber, followed by concise description of macroscopic and microscopic features. Nearly all comments are accompanied by accurate line drawings highlighting structural patterns and specific features. Moreover, a series of excellent half-tone illustrations cover a wide range of magnifications on macroscopic, microscopic and SEM level and explain structural features of the woods in question. In addition,

Wood properties related to pulp and paper quality in two <i>Macaranga</i> species naturally regenerated in secondary forests, Central Kalimantan, Indonesia

“…The previously reported range of basic densities of wood from Macaranga species was about 0.30 to 0.45 g cm -3 (Killmann 1990, Suzuki 1999a, Ogata et al 2008, Chin et al 2013. Killmann (1990) reported a basic density for M. hosei wood of 0.27 to 0.34 g cm -3…”

“…The vessel diameter was smaller and the vessel element length was longer in M. bancana than in M. pearsoni . Information about the anatomical characteristics of Macaranga species is very limited, although Ogata et al (2008) reported vessel diameters of 100 to 180 µm and fiber lengths of 1.0 to 2.0 mm in Macaranga species. The vessel diameters and fiber lengths reported in the present study for M. bancana and M. pearsoni were therefore similar to those reported by Ogata et al (2008).…”

Wood with long and large diameter vessel elements produces paper showing vessel picking which vessel elements are picked from the surface of paper during the printing process and are deposited on the printing surface (Hudson et al 1998, Drew andPammenter 2006).…”

“…In Indonesia, Macaranga trees are commonly found in secondary forests that have regenerated naturally after shifting cultivation. However, little information is available regarding the wood properties and anatomical characteristics for this genus (Killmann 1990, Sosef et al 1998, Ogata et al 2008. The main objective of this study was to explore the potential utilization of the wood resources from unutilized fast-growing tree species found in secondary forests in Indonesia.…”

Occurrence and anatomical features of growth rings in tropical rainforest trees in Peninsular Malaysia: a preliminary study

“…The climate of AHFR is also classified as tropical rainforest, but with a short dry period for 1-2 months in June and July. Table 1 summarizes the selection of tree species, as well as the information regarding their growth rings from the literature available (FRIM 1993;PROSEA 1994a, b, c;Ogata et al 2008). We investigated the occurrence and anatomical features of growth rings in five tree species, belonging to three families, planted in MAFR; five tree species, belonging to four families, planted in BHFRIM; and 26 tree species, belonging to 18 families that grow naturally in AHFR.…”
