Nez Perce National Historical Park includes multiple sites across parts of Montana, Idaho, Oregon, and Washington in the northwestern U.S. Traditional Nez Perce culture was closely tied with the natural world, and plants had great importance materially and spiritually. Plants contributed to traditional Nez Perce culture in both material and spiritual dimensions. The extant vegetation varies from natural to semi-natural and from grassland to woodland stands among the seven sites with some similarities of plant communities between sites.

The Nez Perce National Historical Park 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.
