Fig. 2: Confusion charts for the identification of wood samples to their respective origin.

Identification was based on A pSNPs (SNP), B three stable isotope ratios (ISO), C multi-element analysis of 44 trace elements (EL) and D all three combined. Mean identification accuracy across all sites is indicated in the bottom left. Each site has a unique colour, shown in the inner circle and in the legend. Colours in the outer circle of each symbol indicate to which (other) site(s) the trees of that site were assigned. Primary tropical forest extent from Global Forest Watch is indicated in grey84.
