The Macroscopic Identification Atlas of Endangered Woods Common in Trade was edited by the Wildlife Conservation Department of China National Forestry and Grassland Adminis tration (NFGA), the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) Management Authority of China and the Research Institute of Wood Industry, Chinese Academy of Forestry, with the support of the International Association of Wood Anat omists (IAWA) and the Research Group 5.16.00 of the International Union of Forest Research Organization (IUFRO). In the atlas, a total of twenty-six tree species listed in the CITES Appendices, were included. The taxonomy, geographic distribution, morphological characteristics of trees, wood description, identification characteristics of wood, type of wood products, and conservation class of each species is reviewed. Moreover, key identification features, in comparison with the similar (easy to be confused or look-alike) species, are indicated with images of solid wood and at low magnification under the stereomicroscope. The atlas is portable and suitable for on-site inspection and law enforcement training. It will provide an important reference for law enforcement and customs of China, and strengthen management of imports and exports of endangered tree species. Meanwhile, the atlas will assist the popularization of wood science for the public.
