Up to 90 percent of tropical timber is illegally sourced. To eliminate this illegal trade, independent tools are needed to verify timber legality. Therefore, we are developing a fast, accurate and cost-effective forensic tool for tracing the claimed origin of tropical timber: Timtrace.
Timtrace verifies the geographical origin of tropical timber. We apply multiple methods:
(1) chemical methods, including stable isotopes (e.g. δ13C, δ18O, δ15N), trace elements and rare earth elements in wood that can be matched with regional reference data and
(2) genetic analyses, using microsatellite markers and SNPs to distinguish trees from different populations.
