สรุป	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.	Canopy cover, or canopy closure, is the proportion of ground area covered by tree crowns when viewed from above, typically expressed as a percentage. Formalized by Jennings and colleagues in pioneering work on tropical forest structure, canopy cover estimation employs multiple methods—from field-based ocular assessment to sophisticated remote sensing and terrestrial LiDAR—providing essential data on forest structure, light availability, and habitat characteristics relevant to ecology, silviculture, and climate research.
