This dataset was compiled by the USDA Forest Service Region 1 and Region 4 for the State of Idaho Roadless Rule Draft Environmental Impact Statement(DEIS) 20260428 Final EIS Version vector digital data The BdyPlan_RoadlessArea_2008_ID feature class describes the boundaries of Roadless Areas designated by the Idaho Roadless Rule of 2008 and managed by the US Forest Service. The final rule reflects the views and concerns of thousands of people who expressed interest during the rule-making process, which ran from October 2006 to October 2008. The public comment period generated 38,000 comments.The Idaho Roadless Rule takes a balanced approach, recognizing both local and national interests. Five management themes have been established (and are identified in the MgmtClassification attribute) that provide prohibitions, with exceptions or conditioned permissions, governing timber cutting, removing and selling, road construction and reconstruction, and certain mineral activities. These management themes are: Wild Land Recreation, Special Areas of Historic or Tribal Significance, Primitive, Backcountry Restoration, and General Forest, Rangeland, and Grassland. Each theme provides management direction that varies from most restrictive to least restrictive and provides roadless character that varies from higher quality to lower quality. Forest Plan Special Areas are also identified, where management of the area is according to Forest Plan direction, not the Idaho Roadless Rule. These special areas include items such as wild and scenic river corridors, research natural areas, etc.This dataset is a compilation of the most up to date Roadless areas from the National Forests in Idaho.This dataset was compiled by taking the roadless area boundaries from each of the National Forests in Idaho and adding the management area prescription boundaries from each forest. For some forests both the existing forest plan management prescription layer and a "proposed" prescriptions boundaries were used. See the list of these Forests in the metadata for the each forest.Date of last update: April 2026. See Lineage for details. The BdyPlan_RoadlessArea_2008_ID feature class describes the boundaries of Roadless Areas designated by the Idaho Roadless Rule of 2008 and managed by the US Forest Service. The Idaho Roadless Rule provides management direction for conserving and managing approximately 9.3 million acres of Idaho Roadless Areas (IRAs) on National Forest System lands and replaces the roadless areas identified in the 2001 Roadless Area Conservation Rule. The Chief of the Forest Service may modify or make administrative corrections to the boundaries of any IRA after public notice and comment and coordination with the state. This data reflects the selected alternative of the Idaho Roadless FEIS. unknown publication date Complete As needed -117.034085 -111.042990 48.999594 41.993959 None Idaho Roadless Area boundaries ISO 19115 Topic Categories boundaries None Caribou National Forest Clearwater National Forest Salmon National Forest Idaho Sawtooth National Forest Boise National Forest Wallowa-Whitman National Forest Kootenai National Forest Idaho Panhandle National Forest Targhee National Forest Payette National Forest Challis National Forest This data is being made available to the public upon request and through the Idaho Roadless Rule website.

The National Forest Plan Management Prescription layer for each forest was then overlayed with the Roadless Area boundary. For some forests present Forest Plan management prescriptions were used for the Existing Forest Plan Theme assignment (generally 1987 vintage) and the Forest Plan Revision prescription layer was overlayed and used to assign the State Roadless Rule Theme. The separate datasets were then edge matched and brought together into one dataset. The Idaho Roadless Rule Themes were than applied to each polygon based on the management prescription cross walk to the themes. Themes for Idaho Roadless Rule alternative were not always uniformly applied by prescription and some roadless areas were split on lines other than management prescription in order to assign the State of Idaho's desired theme to an area. The Existing forest plan prescriptions were used for Alternative 3 and applied uniformly across all prescriptions. The Modified Proposal Themes were then applied to each roadless area based on requested changes by the State and National Forests and by public comment. The dataset was then edge matched with Wilderness area boundaries. The edge matching process altered the boundaries of the roadless areas slightly when done between forests and the wilderness boundary.

Ogden UT 84401 (801) 625-5766 8:30 am - 4:00 pm MST UPDATE: The changes proposed and approved by the Payette National Forest are reflected in this latest version of the Idaho Roadless Areas. Roadless Areas affected by the changes include: Big Creek Fringe, French Creek, Placer Creek, Secesh, and Smith Creek. Updates were made based on approved changes to Idaho Roadless Rule themes and boundaries of the IRA on the Payette National Forest in March 2011. For more information visit: http://www.fs.usda.gov/roadmain/roadless/idahoroadlessrule 20110301 UPDATE: R04 GIS Lab - T.Rhoades 6/2014 ===>> To prepare this data for inclusion into the Forest Service Enterprise Data Warehouse (EDW), the data was modified to meet EDW standards. The following changes were made to the original fields: ROADLESS_NAME - renamed to RoadlessAreaName; FOREST - renamed to ForestPlanningUnitName; MIRR_022011 (alias FEIS_SELECTED_ALTERNATIVE) - renamed to MgmtClassification; DATE_OF_LAST_UPDATE - field dropped. This field was tracking the Payette corrections and splitting roadless areas into multiple polygons. This information was deemed unnecessary, the field was dropped and polygons merged so official acres could be coded on the data. The following records were deemed unnecessary to the data and therefore deleted: "ROADLESS_NAME" in ( 'NOT A ROADLESS AREA', 'NOT FS', 'PVT'); "MIRR_022011" = 'NOT FS' The following fields were added to the data: MgmtClassificationCode; RegionCode_ca2008; RegionName_ca2008; ForestCode_ca2008; ForestName_ca2008; ForestOrgCode_ca2008; StateCode; StateName; Acres 20140601 USDA Forest Service Intermountain Region Teresa Rhoades Regional GIS Coordinator UPDATE: R04 GIS Lab - T.Rhoades 7/2014 ===>> Idaho Panhandle National Forest boundary modifications and corrections resulting from June 11, 2014 Federal Register notification - http://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprd3805148.pdf have been completed on this dataset. The U.S. Department of Agriculture (USDA), Forest Service is modifying the boundaries for the BigCreek, Grandmother Mountain, PinchotButte, Roland Point, and Wonderful Peak Idaho Roadless Areas on the Idaho Panhandle National Forests to include lands acquired within and/or adjacent to these roadless areas. In addition, the Forest Service is correcting mapping errors involving Forest Plan Special Areas in the Salmo-Priest and Upper Priest Idaho Roadless Areas. For more information, please visit: http://www.fs.usda.gov/detail/roadless/idahoroadlessrule/?cid=stelprdb5382399 Linework that was used to create the August 28, 2012 proposal maps as well as the current authoritative land ownership data were referenced for the modifications/corrections. Using current ownership data did result in a 3 acre difference on Grandmother Mountain. 20140714 USDA Forest Service Intermountain Region Teresa Rhoades Regional GIS Coordinator UPDATE: R04 GIS Lab - T.Rhoades 9/2015 ===>> Caribou-Targhee National Forest boundary modifications and corrections resulting from July8, 2015 Federal Register notification - http://www.fs.usda.gov/Internet/FSE_DOCUMENTS/stelprd3846255.pdf have been completed on this dataset. The U.S. Department of Agriculture (USDA), Forest Service is modifying the West Mink Idaho Roadless Area boundary on the Caribou-Targhee National Forest to relocate and expand the Gibson Jack Trailhead. For more information, please visit: http://www.fs.usda.gov/detail/roadless/idahoroadlessrule/?cid=stelprdb5382399 Linework that was provided by the forest was used in the modification. 20150918 UPDATE: R04 GIS Lab - T.Rhoades 4/21/2026 ===>> Updates to reflect the overlap of designated wilderness and the Boulder-White Clouds and Railroad Ridge IRAs, requested by the Idaho Roadless Commission. Briefing materials from the Idaho Roadless Rule Coordinator and WO Ecosystem Management Coordination used to prepare edits. In areas of overlap, existing management classifications were replaced with 'Managed as Designated Wilderness (code - MDW). USDA Forest Service Enterprise Data Warehouse utilized as the source data for wilderness boundaries (data extracted 4/21/2026). 20260421 UPDATE: R04 GIS Lab - T.Rhoades 4/21/2026 ===>> The Acres attribute (official acres as reported in the Idaho Roadless Area Final Rule document) was removed.
