Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 05:30 AM | Dataset Last Updated: January 28, 2026 at 12:00 AM
As part of Upper Mississippi River Restoration (UMRR), the U.S. Army Corps of Engineers (USACE) is conducting a study to understand what environmental factors are contributing to the regeneration of floodplain forest. This dataset uses lidar derivatives to identify forest canopy gaps along select portions of the Mississippi River and Illinois River. USACE will use this dataset to select field sites to collect data in forest canopy gaps. This will also serve as the baseline for long-term forest canopy gap study.
