Tumacácori National Historical Park is located in southern Arizona, along the Santa Cruz River valley, which is part of the southern Basin and Range physiographic province. The vegetation is composed primarily of cottonwood–willow riparian forest and woodland along the Santa Cruz River channel, and mesquite forest and woodland on low terraces flanking the river, with a gradation to savanna, semi-desert grassland, and desertscrub on the uplands away from the river.

The Tumacacori 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.
