B32B:
Drivers and Consequences of Changing Forest Productivity Using Individual-Based Models, Remote Sensing, and Field Measurements I

Submit an Abstract to this Session



Session ID#: 35641

Session Description:
Forests cover vast expanses and provide a wide range of goods and services. Some reports indicate widespread forest productivity declines in recent decades coincident with warming and associated increases in drought, fire, and insect outbreak (often referred to as a "browning" trend), while others indicate a broad stasis or even increasing productivity (a "greening" trend). Key next steps include improved change detection, reconciling diverse evidence, and increased understanding of underlying mechanisms. This session will focus on the drivers and consequences of forest browning or greening, as well as related productivity, demographic, compositional and structural changes. Submissions reporting research that uses a range of tools are encouraged, including ground-based measurements, remote sensing, and/or process based models. We especially encourage submissions that diagnose patterns and/or causes of vegetation change, assess the consequences for ecological services, provide improved mechanistic understanding, or reconcile multiple lines of evidence.
