As of January 21st 2016, tribal areas and subdivisions for American Indian/Alaska Native/Native Hawaiian (AIANNH) are available to select in the TRACS system (all environments including live and training)!


What are tribal areas and subdivisions?

These shapefiles are from the U.S. Census TIGER line data (

  • Tribal areas include "federally recognized American Indian reservations and off-reservation trust land areas, the tribal subdivisions that can divide these entities, state-recognized American Indian reservations, Alaska Native regional corporations, and Hawaiian home lands". 
  • Tribal subdivisions include "additions, administrative areas, areas, chapters, county districts, communities, districts, or segments, and legal administrative subdivisions" of federally recognized tribal areas. 

Note: Full definitions can be found here:


How to find the Tribal Layers:

 Tribal areas and subdivisions are available to select in the "Select an Existing Boundary" tool (also known as the Geopicker) for the plan, project or action. 

 Select the Political Boundary type and then select one of the following:

  • Tribal Areas by Region (AIANNH): Tribal Areas by U.S. Fish and Wildlife Region 
  • Tribal Areas by State (AIANNH): Tribal Areas by U.S. State
  • Tribal Subdivisions by Region: Tribal Subdivisions by U.S. Fish and Wildlife Region
  • Tribal Subdivisions by State: Tribal Subdivisions by U.S. State


Choose the State or Region from the top box and then choose the Tribal Area(s) or Subdivision(s) from the bottom box. Tip: To select more than one area or subdivision, hold down the Ctrl key). Click Select at the bottom of the window to create a polygon using the selected area(s). This will open the properties form on the Guided Process Tool where you can continue entering the project or action data. 



To see the tribal boundary selected for the project, search for the project using the Guided Process Tool and click Zoom to Project Location and Apply Feature Filter. Alternate Option: Click Edit Project and select Edit Project Shape to view the tribal area.
