This part of the Navajo Nation where Hubbell Trading Post National Historic Site is located is a Pinyon- Juniper Woodland ecosystem with typical foliage for that environment. As is true in all places precipitation dictates the vigor in which vegetation grows. In dry years plant cover is sporadic, whereas in wet years, the entire ground can be covered with vegetation. The more prevalent plants at Hubbell are shrub-like and include rabbitbrush, sagebrush and four-wing saltbush.

The Hubbell Trading Post 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.
