概要	Forest biodiversity indices quantify species richness, evenness, and overall diversity in forest ecosystems. Rooted in information theory (Shannon) and statistical ecology (Simpson, Magurran), these indices compress complex multispecies data into interpretable metrics. Applied to forest inventory data, biodiversity indices guide conservation planning, assess ecological health, and track responses to management or disturbance.	Forest fire risk assessment quantifies the probability and potential severity of wildfire in forest ecosystems, integrating stand structure, fuel characteristics, weather patterns, and topography. Developed by Van Wagner, Rothermel, and fire science communities, fire risk models predict fire ignition likelihood, fire behavior (spread rate, intensity), and consequences (area burned, damage extent). Essential for land management planning, community protection, and ecosystem conservation.
