OverviewEffigy Mounds National Monument is in a transition zone of several vegetation communities. The monument was created from the acquisition of private land that had been farmed and logged altering the native vegetation mosaic. Results of monument vegetation surveys combined with information from federal land surveys show that a mosaic of forest, savanna, and prairie covered the monument. Prairie and savanna dominated ridges and south facing slopes. Forests pockets were likely found on north facing slopes and in the river floodplain.
The Effigy Mounds National Monument 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.
