This project, known as the Tsali Forest Health Restoration Project is proposed for compartments 152,153,154,155, and 156 across the Tsali Peninsula for the next several years. The District Ranger or Forest Supervisor will use this information to decide whether or not the Forest Service will proceed with this project, and if so, how to proceed. Other government agencies, groups, individuals, and Forest Service personnel interested and concerned about the potential outcome of this project will also use this publication as a basis for critiquing the various courses of action. Finally, this publication will be used by Forest Service personnel for implementation and monitoring if the decision is made to proceed. This document presents: - The proposed action - Why the action is being proposed (Purpose and Need) - Analysis of existing conditions - Project objectives - Public involvement with the analysis - Issues associated with the proposed action - Alternatives considered including the proposed action - Environmental impacts and analysis The Proposed Action The Forest Service is proposing to implement forest management practices on up to 1693 acres in the area known as The Tsali Recreation Area to reduce the impact forest health threats like southern pine beetle, gypsy moth, and the complex disease known as oak decline can and in recent years, have, impacted forest ecosystems at Tsali. The proposed life span of this project is expected to be fiv to seven years and also includes improvements to wildlife habitat and the recreation experience by providing additional habitat for featured wildlife species across the Tsali
