INTRODUCTION
This project is being funded by NASA's North American Carbon Program and the USDA Forest Service.
NAFD is combining the USFS FIA and Landsat information sources to characterize recent trends in North American forest disturbance and regrowth. Initial projects by this team have shown that the basic patterns of disturbance can be evaluated using change detection methods and that regrowth can be evaluated from inferences of forest structural change noted by spectral reflectance changes. Collaboration with the US Forest Service has provided important access to Forest Inventory and Analysis (FIA) data that permit direct comparison of the satellite-based spectral reflectance patterns with ground-based forest structural attributes.
