Dendroclimatological research, both ring-width and isotopes, on tropical and subtropical broadleaf trees, is rapidly offering new insights into climate reconstruction, ecosystem dynamics, etc. Despite this, these species remain underrepresented in tree-ring studies, largely due to challenges in cross- dating annual rings. Historically, dendroclimatic research has focused on conifers in high-altitude and high-latitude regions, leaving significant gaps in our understanding of remaining forests. Recent methodological improvements have enabled more accurate dating and standardisation of broadleaf species, opening new opportunities to study forest resilience, carbon sequestration, and climate– vegetation interactions. This session highlights innovative work addressing cross-dating difficulties and explores how dendrochronology can enhance our understanding of past climate change in tropical and subtropical ecosystems, including the impacts of deforestation on regional climate processes.
