This map was to adhere to the directions specified in Subpart B of the Forest Service Travel Management Rule (rule), regarding designation of roads, trails, and areas for motor vehicle use. The rule consists of two other Subparts: Subpart A, which covers the administration of the Forest transportation system, and Subpart C, which covers use by over- snow vehicles. By the end of 2010, approximately 93 percent of the National Forest System Lands were covered by an MVUM1. These maps only followed directions specified in Subpart B, but in order to identify opportunities for the forest transportation system to meet current or future management objectives, based on ecological, social, cultural, and economic concerns, the National Forests also needed to adhere to the directions specified in Subpart A. On November 10, 2010, the Washington Office directed the National Forests to complete Subpart A of the rule, which would require each unit to: Identify the minimum road system needed for safe and efficient travel and for the protection, management, and use of NFS lands; and Identify roads that are no longer needed to meet forest resource management objectives and therefore, scheduled for decommissioning or considered for other uses (36 CFR 212.5(b)). With this direction given, the District Ranger for the Fairfield Ranger District has directed an interdisciplinary team to identify the minimum road system and unneeded roads using a travel analysis process that is dynamic, interdisciplinary, and integrated with all resource areas. The travel analysis process (TAP) will follow directives described in Forest Service Manual 7712 and Forest Service Handbook (FSH) 7709.55, Chapter 20, to complete the applicable sections of Subpart A. This analysis includes all National Forest System roads, maintenance levels 1-5, on lands located within the Fairfield district on the Sawtooth NF. The analysis will not evaluate existing motorized trails or non-system roads but will consider their existence when performing the analysis. Roads Analysis Objective The objective of the roads analysis is to provide the line officer with critical information that is used to develop a road system that is safe and responsive to public needs and desires, adheres to the Sawtooth National Forest’s Land and Resource Management Plan (Forest Plan), meets 1 Cited in letter sent by Joel D. Holtrop, Deputy Chief, National Forest System, “Travel Management, Implementation of 36 CFR, Part 212, Subpart A (36 CFR 212.5(b)”, November 10, 2010 3 | P a g e current and future resource management objectives, reverses or minimizes negative ecological effects on the land, and allows for economical and efficient road management within likely budget levels. To meet these objectives, as stated previously, Forest Service Manual (FSM) 7712 requires an interdisciplinary team conduct a science-based roads analysis process. A process meeting the requirements is described in the report Roads Analysis: Informing Decisions About Managing the National Forest Transportation System (USDA Forest Service, 1999, Misc. Report FS-643). The interdisciplinary team conducting the science-based roads analysis consisted of the following: Team Member Title / Specialty Shawn Robnett Forest’s Assistant Engineer / Engineering Steve Frost Fairfield RD Recreation Manager / Recreation Mark Dallon Fairfield RD Hydrologist / Hydrology Erika Phillips Fairfield RD Aquatics Biologist / Aquatics David Skinner Fairfield RD Wildlife Biologist / Wildlife John Pine Fairfield RD Forester / Timber Management John Shelley Fairfield RD Rangeland Mgmt. Specialist / Range & Weeds Devin Hulme Fairfield RD Fire Management Officer / Fire & Fuels Heidie Torrealday Forest’s Geologist / Minerals Dave Stockdale Forest GIS Specialist / Mapping The science-based roads analysis provides a written document that contains the necessary information for the line officer to: 1. Identify transportation management opportunities and priorities. 2. Assess transportation management needs, long-term funding, and expected ecosystem, social, and economic effects. 3. Establish transportation management objectives and priorities. The final result of the roads analysis is a written document with accompanying maps that document the information and analysis methods used to identify social and environmental opportunities, issues, risks, and priorities for future road management. The report, at a minimum, should contain the following: 1. Identification of needed and unneeded roads. 2. Identification of road-associated environmental and public safety risks. 3. Identification of site-specific priorities and opportunities for road improvements, decommissioning, and conversion to other uses. 4. Identification of areas of special sensitivity, unique resource values, or both. 5. Any other specific information that may be needed to support project-level decisions. 4 | P a g e It should be noted here the information and final recommendations in this TAP represents the best available information at this time. This document is an analysis tool to be used for guiding future planning documents such as Environmental Analysis, Environmental Impact Statements or Categorical Exclusions. It is not intended to be a decision making document by itself. Project Area and Existing Transportation System Project Area The Fairfield Ranger District is located in the southwest portion of the northern half of the Sawtooth National Forest. The District lies mostly within Camas County with a small portion of it in the western section of Elmore County. The District encompasses 420,720 acres of Forest system administered lands and contains 440 miles of inventoried trails, twelve campgrounds, over 680 miles of streams and more than 20 high mountain lakes. Existing Transportation System The existing road system on the Fairfield Ranger District consists of 369.78 miles of forest roads. A “Forest Road” is a road wholly or partly within or adjacent to and serving the National Forest System that the Forest Service determines is necessary for the protection, administration and utilization of the National Forest System and the use and development
