The vegetation of Hopewell Furnace National Historic Site was mapped during 2002 and 2003 as part of the U.S. Geological Survey (USGS) / National Park Service (NPS) Vegetation Mapping Program. The goal of the mapping effort was to produce an up-to-date digital geospatial vegetation database for the park. New aerial photography was obtained for the park in spring 2002 by Kucera International and converted to a digital orthophoto mosaic image by the North Carolina State University Center for Earth Observation in early summer 2002. The Pennsylvania Science Office of The Nature Conservancy (PSO/TNC) interpreted the photography and developed a digital formation-level vegetation map. PSO/TNC sampled 35 vegetation classification plots during the summer of 2003. Data analysis identified 12 natural or semi-natural vegetation types.
