Vegetation Classification and Mapping of Herbert Hoover National Historic Site, Iowa. Project Report.

摘要

Herbert Hoover National Historic Site (HEHO) is situated in east central Iowa, surrounded by the small town of West Branch, just north of, and adjacent to, Interstate 80. The Herbert Hoover Library and Museum, a visitor center, and a number of restored homes and other buildings are present within the park. A restored tallgrass prairie is the most significant terrestrial natural resource within this largely agricultural landscape. A vegetation classification and mapping project was initiated in 2011 and completed in 2013. Protocols and products were produced following National Park Service Vegetation Inventory Program guidelines. Classification was based on 15 field plots and 24 georeferenced observation points. Mapping was based on air photo interpretation and heads-up digitizing of polygons. Accuracy assessment points obtained during 2013 verified that the map was 98.7% accurate.
