Data criteria and suitability categories were developed by the ELWG and vetted with the Technical Committee and Western Governors Wildlife Council. State and Provincial data coordinators provided data according to the criteria which were then clipped to the Qualified Resource Area (QRA) boundaries. Suitability categorization was then applied according the instructions of the data coordinators or conducted by NatureServe and approved by the data coordinators. In some cases States or Provinces conducted their own data manipulation and categorization and submitted to NatureServe for integration into the regional map. Iterations were performed and presented to the ELWG and WGWC which in some cases resulted in revisions by the states.
