Walker Basin History & Data

The University of Arizona, College of Agriculture and Life Sciences’ V Bar V Ranch operates on the Walker Basin Allotment in the Coconino National Forest in central Arizona. Over the years, there has been a systematic collection of natural resource data on the Walker Basin Allotment to meet federal environmental regulations such as those defined in the National Environmental Policy Act (NEPA), the Endangered Species Act (ESA), and the Clean Water Act. This U.S. Forest Service (USFS) allotment is representative of similar allotments throughout the West and, thus, the historical information provided on the Walker Basin Allotment website provides an example of a representative set of public lands information. The purpose is to provide a model for others to build allotment data sets and a records archive and, thus, to maximize past financial inputs, offer new planning opportunities, and facilitate compliance with federal laws and regulations.
