Making wood identification easier for foresters [NZ]Friday 19 Jun 2026
“We use a technique called Direct Analysis in Real Time mass spectrometry to analyse the chemical fingerprint of wood,” Bioeconomy Science Institute analytical chemistry team lead Ilena Isak says. “Specifically focusing on Podocarpus totara from New Zealand, Eucalyptus saligna from Australia and Pinus radiata imported from California and grown in NZ. Each species has its own chemical signature, which allows us to distinguish between them. “This analysis technique has potential to support non-experts in identifying wood species – giving us the opportunity to move towards tools that could be used beyond specialist labs.” New Zealand forestry encompasses a mix of native and exotic species, necessitating precise species identification for sustainable management and compliance with trade regulations. Wood differentiation helps ensure the right resource is being used for the right purpose. “It improves confidence in wood supply chains, supports compliance and traceability and enables higher-value uses of timber,” Ilena says. “It also reduces reliance on individual expertise and moves towards more consistent, accessible tools.” Next steps for this research include expanding datasets, refining the method and working towards more portable and practical applications. “Ultimately, the goal is to make wood identification faster, more reliable and more widely accessible,” Ilena says. “We hope to secure funding to help us work towards that goal and build industry interest.” This research is part of the Bioeconomy Science Institute’s wider work to unlock more value from NZ’s natural resources – turning knowledge into practical tools that support a more sustainable, high-value bioeconomy.
