The Alaska National Interest Lands Conservation Act of December 2, 1980 defined the external boundaries of 16 National Wildlife Refuges and 10 Designated Refuge Wilderness Areas within the State of Alaska. The USFWS Region 7 Division of Realty has digitized these boundaries and they can be downloaded from the links shown below.

Note that the boundaries available here represent the outermost, external boundary of the refuges and wilderness areas. Internal boundaries between refuge/wilderness and private parcels of land are not depicted in these files. For the boundaries of private parcels within the external refuge/wilderness boundaries, refer to the land status download page.

Refuge and wilderness boundaries are available in three formats:

ESRI File Geodatabase and ESRI Shapefile

The file geodatabase format can be used in ESRI's ArcGIS program. The shapefiles can be used in ArcGIS, other GIS mapping programs that support shapefiles, and other programs, such as Google Earth Pro, which support the shapefiles format.

GPX

The GPX format is a universal format for use with GPS units. You can load the refuge and wilderness GPX files into your GPS for use in the field.
