Forest Service Enterprise Data Warehouse (EDW) Surface Ownership updated with saltwater shoreline Mean High Water Combined Source (MHW_CS). Note, Forest service land areas were updated to MHW_CS shoreline, while non-forest service areas were not. This data is intended for read-only use. Surface Ownership is a commonly used base layer used in a wide range of Forest Service business functions as well as those of other entities.

Forest Service Enterprise Data Warehouse (EDW) Surface Ownership updated with saltwater shoreline Mean High Water Combined Source (MHW_CS). Forest service Shoreline Integration Tool was employed to accomplish this update. Note, Forest service land areas were updated to MHW_CS shoreline, while non-forest service areas were not. The Forest Service prepared this dataset to support the Tongass National Forest (TNF) plan revision GIS analysis. This 2025 update builds upon the 2024 TNF forest plan assessment analysis incorporating all available NOAA CUSP shoreline updates, including additional Lidar derived shoreline. Forest Service Lands Team is updating Land Status Record System (LSRS) in 2024/2025 with expected completion and publication to EDW in 2026. These data may not be used to determine title, ownership, legal descriptions or boundaries, legal jurisdiction, or restrictions that may be in place on either public or private land.
The Forest Service has multiple types of boundaries represented by different feature classes (layers): Administrative, Ownership and Proclaimed.
1) ADMINISTRATIVE boundaries (e.g. AdministrativeForest and RangerDistrict feature classes) encompass National Forest System lands managed by an administrative unit. These are dynamic layers that should not be considered "legal" boundaries as they are simply intended to identify the specific organizational units that administer areas. As lands are acquired and disposed, the administrative boundaries are adjusted to expand or shrink accordingly. Please note that ranger districts are sub units of National Forests. An administrative forest boundary can contain one or more Proclaimed National Forests, National Grasslands, Purchase Units, Research and Experimental Areas, Land Utilization Projects and various "Other" Areas. If needed, OWNERSHIP boundaries (e.g. BasicOwnership and SurfaceOwnership feature classes) should be reviewed along with these datasets to determine parcels that are federally managed within the administrative boundaries.
2) OWNERSHIP boundaries (e.g. BasicOwnership and SurfaceOwnership feature classes) represent parcels that are tied to legal transactions of ownership. These are parcels of Federal land managed by the USDA Forest Service. Please note that the BasicOwnership layer is simply a dissolved version of the SurfaceOwnership layer.
3) PROCLAIMED boundaries (e.g. ProclaimedForest and ProclaimedForest_Grassland) encompass areas of National Forest System land that is set aside and reserved from public domain by executive order or proclamation. Please note that the ProclaimedForest layer contains only proclaimed forests while ProclaimedForest_Grassland layer contains both proclaimed forests and proclaimed grasslands. For boundaries that reflect current National Forest System lands managed by an administrative unit, see the ADMINISTRATIVE boundaries (AdministrativeForest and RangerDistrict feature classes).
For a visual comparison of the different kinds of USFS boundary datasets maintained by the USFS, see the Forest Service Boundary Comparison map at https://usfs.maps.arcgis.com/apps/CompareAnalysis/index.html?appid=fe7b9f56217949a291356f08cfccb119.
USFS boundaries are often referenced in national datasets maintained by other federal agencies. Please note that variations may be found between USFS data and other boundary datasets due to differing update frequencies. PAD-US (Protected Areas Database of the United States), maintained by the U.S. Geological Survey, is a "best available" inventory of protected areas including data provided by managing agencies and organizations including the Forest Service. For more information see https://gapanalysis.usgs.gov/padus/data/metadata/. SMA (Surface Management Agency), maintained by the Bureau of Land Management, depicts Federal land for the United States and classifies this land by its active Federal surface managing agency. It uses data provided by the Forest Service and other agencies, combined with National Regional Offices collection efforts. For more information see https://landscape.blm.gov/geoportal/catalog/search/resource/details.page?uuid=%7B2A8B8906-7711-4AF7-9510-C6C7FD991177%7D.
