Red Spruce-Northern Hardwood Ecotone Forest Measurements in the Central Appalachian Mountains

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: August 01, 2026 at 05:25 AM | Dataset Last Updated: April 28, 2026 at 12:00 AM
This dataset contains long-term measurements of red spruce-northern hardwood ecotone forests in the central Appalachian Mountains. To evaluate long-term dynamics in unmanaged red spruce–northern hardwood forests, ten ecotone transects were installed in 1992-1994 across the central Appalachians. The ten ecotone transects were remeasured in 2003-2005 and 2023-2025 to assess post-exploitation recovery or lack thereof. Measurements were taken to identify changes in forest structure and composition in the tree, sapling, and seedling strata.
