概要	Silvicultural treatment design is the process of developing specific management prescriptions for forest stands to achieve defined objectives (timber yield, biodiversity, carbon storage, watershed protection). Codified in foundational texts by Smith and colleagues, silvicultural design integrates stand assessment, growth models, and ecosystem understanding to specify interventions (thinning, shelterwood, clear-cut, rotation-age modification) that steer forest development toward intended outcomes while respecting ecological constraints.	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.
