Space and airborne active and passive remote sensing data will provide information at large spatial scales, and can infer mortality from changes in canopy cover, sometimes close to realtime.
Forest Inventory and Monitoring
National forest inventories, research plot networks and citizen science approaches provide trends and indicators at tree or stand level.
Large-scale vegetation models underlie IPCC assessments and are increasingly important for policy making, but suffer from limited understanding of mortality mechanisms.
Research of ecophysiological responses of trees to changes in the environment can provide mechanistic mortality relationships, improving predictive capacity.
