Chaco Culture National Historical Park's vegetation is predominantly Great Basin grassland and desert scrub. Riparian vegetation, including cottonwood and willow groves, are locally abundant along the arroyo within the canyon floor and around the few seeps found in the park. Diverse scrub and wildflower communities occur around the sandstone bluffs throughout the canyon. Pinyon-juniper woodland is also well-developed at the park's highest elevations on Chacra Mesa, and along the margins of several other mesas.

The Chaco Culture 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.
