ABoVE: Subsistence Resource Use Areas of Interior Alaskan Communities, 2011-2017

Documentation Revision Date: 2019-10-31

Dataset Version: 1

Summary

This dataset provide maps to show the search and harvest areas used by community residents for all subsistence resources combined across Interior Alaska for the years 2011 through 2017. The maps show the extent of areas used by residents for those communities where data collection and research has occurred; it is not a comprehensive use map for the entire area. The maps are a composite of data collected by the Division of Subsistence, Alaska Department of Fish and Game using standardized methods where respondents indicated the search areas for species harvested, the amounts harvested, and the location and months of harvest. These data are important for research, analysis, and regulatory assessment.

All data were collected under the principles of informed consent and in accordance with the State of Alaska confidentiality statute (AS 16.05.815) and have been reviewed by their respective communities. All data are confidential at the household level and only reported at the community level in the provided maps.

There are three shapefiles provided with this dataset showing community use areas: (1) points marking localized search and harvest areas, (2) polygons indicating larger search and harvest effort areas, and (3) lines indicating linear search and harvesting activity. The data in the shapefiles are provided as companion files in .kmz format for viewing in Google Earth.

Data File Information

There are three compressed (*.zip) shapefiles provided with this dataset showing community use areas: (1) points marking harvest effort locations, (2) polygons indicating harvest effort areas, and (3) lines indicating linear harvesting activity. The data in the shapefiles are provided as companion files in .kmz format for viewing in Google Earth.

There is only a single attribute for each of the maps – indicating the name of the community using the area.  

Data Files:

Interior_Alaska_Subsistence_Use_Areas_Polygons.zip Compressed shapefile with polygons indicating harvest effort areas
Interior_Alaska_Subsistence_Use_Areas_Lines.zip Compressed shapefile with lines indicating linear harvesting activity such as trapping and trolling

Application and Derivation

These data are important for research, analysis and regulatory assessment. Alaska Statute 16.05.094 requires the Division of Subsistence, ADF&G, to conduct studies and compile existing data on all aspects of the role of subsistence hunting and fishing in the lives of state residents. The Division must also make this information available to the public, appropriate agencies, and other bodies. Copies of this map are available for viewing on the Division’s website (https://www.adfg.alaska.gov/) and copies may be made available upon request through the ADF&G office in Fairbanks.

Quality Assessment

Data were collected using a standardized method where respondents indicate the search areas for species harvested, the amounts harvested, and the location and months of harvest. Data collection maps were usually produced for individual projects using ArcGIS software. Survey maps were typically produced at various scales and extents to accommodate both local and distant searches and harvests.

Data Acquisition, Materials, and Methods

The provided maps are a composite of subsistence search areas for Interior Alaska collected by the Division of Subsistence, Alaska Department of Fish and Game (ADF&G) for 2011 to 2017. These data are important for research, analysis and regulatory assessment.

Alaska Statute 16.05.094 requires the Division of Subsistence, ADF&G, to conduct studies and compile existing data on all aspects of the role of subsistence hunting and fishing in the lives of state residents. The Division must also make this information available to the public, appropriate agencies, and other bodies.

The map is a composite of previously collected spatial data depicting the search and harvest areas used by community residents for all subsistence resources combined in specific years. It shows the extent of area in Interior Alaska used by residents for subsistence uses for communities where research has occurred; it is not a comprehensive use map for the area.

Data were collected using a standardized method where respondents indicate the search areas for species harvested, the amounts harvested, and the location and months of harvest.

  • Points were used to mark localized search and harvest areas.
  • Polygons (shaped areas) were used to indicate harvest effort areas, such as areas searched while hunting moose.
  • Lines were also drawn when the harvesting activity did not occur at a specific point, such as trapping and trolling.

Data collection maps were usually produced for individual projects using ArcGIS software. Survey maps were typically produced at various scales and extents to accommodate both local and distant searches and harvests.

All data were collected under the principles of informed consent and in accordance with the State of Alaska confidentiality statute (AS 16.05.815) and have been reviewed by their respective communities. All data are confidential at the household level and only reported on the community level. Copies of this map are available for viewing on the Division’s website (https://www.adfg.alaska.gov/) and copies may be made available upon request through the ADF&G office in Fairbanks.

Data Access
