Timber identification of Autranella, Baillonella and Tieghemella in the taxonomically challenging Sapotaceae family

Addressing the need for standardized wood reference collections to support authentication analysis technologies; a way forward for checking the origin and identity of traded timber
Societal Impact Statement Forest products are the most used inedible renewable resource, but supplies are finite. It is difficult to know which tree species are
To enforce timber import laws and perform timber species identification, the identity of the botanical species must be well-defined. Since the Sapotaceae family is known as a taxonomically challenging family, we focus in this study on the four most valuable Sapotaceae timber species from tropical Africa: Autranella congolensis (De Wild.) A.Chev., Baillonella toxisperma Pierre, Tieghemella africana Pierre and Tieghemella heckelii (A.Chev.) Pierre ex Dubard. The wood anatomical characteristic fiber lumen fraction and Direct Analysis in Real Time—Time of Flight Mass Spectrometry (DART-TOFMS) were used to differentiate the four species and to make inferences on species delineation and taxonomic identity.
Creating verifiable timber origin claims from the Solomon Islands: This study sought to establish scientific methodology to assess geographic origin claims of timber declared to have originated from the Solomon Islands to enable operators to carry out due diligence analysis and permit members of Law Enforcement to conduct forensic investigations.
Protecting forest in Gabon with Stable Isotope testing: This study aimed to assess the differences in stable isotope ratio profile of a variety of timber samples collected from two FSC concessions in Gabon, for the purposes of origin classification, and to enable operators and Law Enforcement agencies to carry out due diligence checks and forensic investigations.
