Isotope map could give Brazil a harder-to-fake test for illegal Amazon timber
Key Takeaways
- Brazilian researchers are building an isotope map of Amazon tree wood for law-enforcement use.
- The method analyzes stable isotopes in cellulose to estimate where timber was harvested.
- Early results show a regional oxygen-isotope gradient across the Amazon that could aid origin checks.
