DNA barcoding technology has emerged as one of the most promising tools available to identify timber at the species level, contributing to the monitoring of the timber trade and the conservation of forestry sources. This paper reviews the progress, challenges, and existing problems in the development of DNA barcoding for wood identification in the last ten years. There is a focus on the optimization of DNA extraction methods for processed or ancient wood, the strategy of screening high-resolution DNA barcodes suitable for wood identification, the development of a wood DNA reference database especially for priority taxa, and the comparison and comprehensive application of sequence analytical methods to achieve accurate identification. In addition to DNA barcoding, the feasibility of other genetic methods for wood identification is also discussed. Furthermore, future research orientation and strategy of wood DNA barcoding are presented. We argue that wood DNA barcoding integrated with other methodologies including wood anatomy can offer an effective approach and a new perspective to promote legal logging for timber trade custody and global biodiversity conservation.
