The project’s proposed activities are designed to move the vegetation in the project area from its existing condition toward the desired conditions described in the forest plan. Key objectives of the Mesabi Project are to promote diverse, productive, and healthy native vegetation communities; improve habitat for sensitive plants; enhance wildlife habitat for threatened, endangered, and sensitive species; introduce fire into fire dependent ecosystems; reduce hazardous fuels; improve riparian function; improve water and soil resource health; improve recreational opportunities; designate gravel pits; provide sustainable forest products; and improve forest health and productivity. Other objectives are described further in this document. Activities proposed to accomplish these objectives include harvesting (such as thinning, clearcut with reserves or shelterwood), hazardous fuels reduction, a full suite of reforestation activities (such as site preparation, seeding, planting (figure 1.1), timber stand improvement (TSI), prescribed burning, and understory fuel reduction. Additional proposed actions include constructing and decommissioning temporary roads to access units, decommissioning roads no longer needed, and designating federal gravel pits needed for projects and public use. The Mesabi Project Area is located in St. Louis County, approximately three miles north of Virginia, Minnesota (figure 1.2). Townships include 59 North, Ranges 16, 17, 18, 19, 20, and 21 West; Township 60 North, Ranges 17, 18, 19, 20, and 21 West; and Township 61 North, Ranges 17, 18, 19, 20, and 21 West. The Mesabi Project Area encompasses approximately 256,984 acres of land with mixed ownership; approximately 101,599 acres (40 percent) are National Forest System land. This environmental assessment was prepared to provide the decision maker (Laurentian District Ranger) and the public with information about the potential effects of proposed vegetation management activities and connected road actions in the project area. An interdisciplinary team of resource specialists prepared this document. Figure 1.1: An example of diversity planting with oak, pine, and spruce.

Laurentian Ranger District 2 Mesabi Project Environmental Assessment 1.2 ORGANIZATION OF THE ENVIRONMENTAL ASSESSMENT This environmental assessment (EA) is organized into four chapters with appendices and follows the format established by the Council on Environmental Quality (CEQ) regulations (40 CFR 1500-1508) for implementing the National Environmental Policy Act (NEPA). Major sections of the EA are as follows: • Chapter 1: Purpose and Need. This chapter provides introductory material that explains the purpose and need for the proposed action, provides background information about the project area, presents pertinent laws and regulations, and describes issues to be addressed. • Chapter 2: Alternatives. This section describes the no action alternative and the action alternatives, all of which are analyzed in detail in chapter 3. Chapter 2 also includes mitigation measures and monitoring procedures that would be used in implementing an action alternative. A summary comparison of the environmental effects for each alternative is also provided. • Chapter 3: Affected Environment and Environmental Effects. This chapter describes the affected environment and the direct, indirect, and cumulative effects likely to occur with the implementation of each alternative. • Chapter 4: References. This chapter provides names of the preparers and contributors to this environmental assessment, a distribution list, and literature cited. An important consideration in the preparation of this EA was the reduction of paperwork as specified in 40 CFR 1500.4. The objective is to furnish enough site-specific information to demonstrate a reasoned consideration of the environmental effects of the alternatives and how any adverse effects can be mitigated or avoided. Additional supporting information is in the Mesabi project record and is available at the Laurentian Ranger District, Aurora, Minnesota or upon request. This environmental assessment is tiered to the Forest Plan Revision Final Environmental Impact Statement (FEIS). Relevant analysis from the Forest Plan Revision FEIS was incorporated by reference rather than repeating the information. 1.3 FOREST PLAN DIRECTION FOR THE MESABI PROJECT AREA The forest plan divides the Superior National Forest outside the Boundary Waters Canoe Area Wilderness (BWCAW) into ten management areas. Chapter 3 of the forest plan (FP) includes the desired conditions, objectives, standards, and guidelines for each management area. The project
