Editing Forest canopy mortality rate (section)

== Monitoring and Measurement ==
Monitoring forest canopy mortality involves a combination of remote sensing technologies, field inventories, and ecological modeling. Satellite imagery, such as high-resolution optical and LiDAR data, enables detection of canopy changes and tree mortality over large areas and extended timeframes. Datasets like deadtrees.earth-aerial provide multi-resolution aerial imagery for tree cover and mortality detection, while LiDAR datasets support detailed forest structure assessments. Ground-based forest inventories complement remote sensing by providing species-level mortality data and causal attribution. Institutions such as the International Tree Mortality Network coordinate data collection and analysis to improve understanding of global tree mortality patterns.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
