Today farms and pastures cover the Iowa countryside but elements of the state's old natural beauty fill out the landscape commemorating Herbert Hoover's life at Herbert Hoover National Historic Site.These cultural features are complimented by a small bottomland woodland, a newly acquired area of retired cropland, and a prairie restoration area. The tallgrass prairie restoration is currently the most significant natural feature within the park. The 81 acres of tallgrass prairie reconstructed here offer a glimpse of an Iowa landscape that had almost vanished by the time Herbert Hoover's grandparents moved here in 1854.

The Herbert Hoover National Historic Site Vegetation Inventory Project delivers many geospatial and vegetation data products, including an in-depth project report discussing methods and results, which include descriptions to vegetation associations, field keys to vegetation associations, map classification, and map-class descriptions. The suite of products also includes a database of vegetation plots, and accuracy assessment (AA) sites; digital images of field sites; digital aerial imagery; digital maps; a contingency table listing AA results; and a geodatabase of vegetation, field sites (vegetation plots, and AA sites), aerial imagery, project boundary, and metadata.


The products of vegetation mapping projects are stored and managed in the National Park Service's Data Store, a repository for documents and publications relating to park resources. From the highlighted items below, click on the type of information you are looking for.
