To evaluate long-term dynamics in unmanaged red spruce\u2013northern 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.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1DQZ9J5", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.69aaf06eb66b01cd2fd12272.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_69aaf06eb66b01cd2fd12272", "keyword": ["Picea rubens", "USGS:69aaf06eb66b01cd2fd12272", "Virginia", "West Virginia", "central Appalachians", "climate change", "ecosystem recovery", "ecosystems", "red spruce"], "modified": "2026-04-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-80.7385, 36.9762, -79.1675, 39.2748", "theme": ["geospatial"], "title": "Red Spruce-Northern Hardwood Ecotone Forest Measurements in the Central Appalachian Mountains"}
