概要	Dendrochronology is the science of dating and analyzing tree rings to reconstruct past climatic conditions, chronologies, and tree growth patterns. Pioneered by Andrew Ellicott Douglass in the early twentieth century and formalized by Fritts and colleagues, dendrochronology enables precise dating of historical wood samples and generates millennial-length climate records, becoming indispensable for paleoclimatology, archaeology, and forest ecology.	Forest carbon stock estimation quantifies the amount of carbon stored in tree biomass and other forest components, typically expressed in tonnes of carbon per hectare. Formalized by Brown, Chave, and international bodies such as the IPCC and FAO, this method is foundational for climate change mitigation accounting, carbon credits, and monitoring progress toward climate commitments. Accurate carbon assessment enables identification of high-priority reforestation areas and verification of carbon offset projects.
