Our Forest Plan was approved in 2005 after several years of extensive environmental analysis and collaboration with the public. Thousands of people repre- senting a variety of interests, sciences, and specialties joined in the effort by way of public meetings, discussions, document reviews and comments, and scientific study to create what is now our 2005 Forest Plan. The Plan is a programmatic framework which documents the agreed-upon balance of multiple uses to meet society’s needs while protecting, restoring, and enhancing our natural resources. The 2005 Forest Plan may be amended at any time. It guides our land management for the next 15 years, when it will be revised again. Until then we will use the manage- ment framework of the 2005 Forest Plan to achieve our goals, objectives, and vision of the desired conditions for the White Mountain National Forest. Implementing the Vision of the Forest Plan: The Mill Brook Vegetation Management Project A team of resource specialists examined the Mill Brook area to assess the current conditions and identify any potential management activities that would move this area closer to the desired conditions described in the Forest Plan. The team decided to propose vegetation management to diversify wildlife habitat and promote a sustained yield of timber products, as well as to conduct two watershed restoration projects in eroding locations along Mill Brook. It also made sense to look at the road system in the area and propose which roads are necessary for long-term management, and which should be decommissioned. On-going field surveys, site-specific data collection, and public involvement helped refine the site-specific proposals and develop alternatives. This document presents the results of the environmental analysis. The Project File contains the supporting data, science, and other information associated with this anal- ysis. Field survey and observations were an important part of project development. This proposal is a revised version of the original proposal presented to the public in March 2006. Court rulings late in 2006 (in consolidated cases California v. USDA and Wilderness Society v. USFS) reinstated the 2001 Roadless Area Conservation Rule (RACR). The RACR prohibits road construction and timber harvest in inventoried roadless areas identified in the RACR, except in narrow circumstances. The original Mill Brook project proposal included about 1,500 acres of forest management and 0.9 miles of connected road construction in the RACR Kilkenny Inventoried Roadless Area. The proposed activities do not meet the exceptions allowed in the RACR. Therefore, we were required to revise the proposal to exclude those acres. The new project is described in Chapter 2, Section 2.2. The land base of the Forest is divided into Habitat Management Units (HMU) as a tool to ensure that habitats are well-distributed across the Forest. HMUs contain a variety of habitat and land types in a mix of Management Areas, and provide a framework for 5 White Mountain National Forest — Androscoggin Ranger District analyzing project impacts to wildlife habitat at a local scale. The Mill Brook project is located in the Mill Brook HMU. Within each HMU there are compartments, which are smaller subdivisions of forest area used for orientation, administration, and silvicultural operations. Distinct features such as rivers, ridges, and roads define compartment boundaries. The Mill Brook project area consists of Compartments 2, 3 and 4 of the Mill Brook HMU in the Kilkenny region of the White Mountain National Forest. See Map 1 in Appendix A. The project is located in the Mill Brook drainage in the Town of Stark in Coos County, NH, on moderately sloped terrain ranging from approximately 1,300 to 2,300 feet in elevation. The forest stands proposed for treatment are northern hard- wood, mixedwood (a mix of hardwoods and softwoods), and spruce-fir types. Management Areas The Mill Brook HMU is comprised of three of the 15 Management Areas (MA) which the Forest Plan allocated across the White Mountain National Forest. Each Management Area emphasizes particular goals, objectives, and desired conditions as described below. Each MA has a set of standards and guidelines that set parameters on activities to ensure protection of the character of the land and goals assigned to the MA. The 17,000-acre Mill Brook HMU includes the following Management Area allocations: MA 2.1: General Forest Management (9,000 acres) allows for a range of uses and activ- ities, including timber harvest, roads, motorized recreation such as snowmobiling, and developed areas such as campgrounds. MA 2.1 is described in the Forest Plan on pages 3-3 through 3-8. MA 6.1: Semi-Primitive Recreation (170 acres) emphasizes non-motorized recreation, but allows motorized trail use in winter. Development levels are kept low, and sched- uled commercial timber harvest and new Forest Roads are not allowed. MA 6.1 is described in the Forest Plan on pages 3-19 through 3-22. MA 6.2: Semi-Primitive Non-Motorized Recreation (7,830 acres) maintains a sense of remoteness in a relatively undisturbed landscape. Timber harvest and roads are prohibited. MA 6.2 is described in the Forest Plan on pages 3-23 through 3-26. MA 6.1 and 6.2 are simply within the analysis area defined by the interdisciplinary team for this project. No ground disturbing or other actions would occur within these areas. All proposed activities in Alternatives 2 and 3 are located in MA 2.1 and are designed to meet the goals
