Bottomland hardwood forest plots in the GTR on Felsenthal National Wildlife Refuge (FNWR) are measured every 5-6 years to monitor tree survival, growth, and mortality. This dataset presents the measurements of all the trees in 54 plots during the year 2001. Parameters measured are species, diameter, vigor class, canopy class, and whether or not the tree is a new recruit in 2001. These parameters are defined in the Entity and Attributes section of this metadata file.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7WW7GZN", "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.5d66d1a2e4b0c4f70cf04406.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5d66d1a2e4b0c4f70cf04406", "keyword": ["Arkansas", "Felsenthal National Wildlife Refuge", "USGS:5d66d1a2e4b0c4f70cf04406", "biota", "bottomland hardwoods", "environment", "forest ecosystems", "green tree reservoir", "green-tree reservoir", "greentree reservoir", "long-term ecological monitoring", "plot sampling", "wetland ecosystems"], "modified": "2020-08-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-92.252971191601, 33.029023497267, -91.991271972852, 33.249807001053", "theme": ["geospatial"], "title": "Felsenthal National Wildlife Refuge green-tree reservoir 2001 forest plot measurements"}
