Ecosystem Recovery Planning for Listed Salmon: An Integrated Assessment Approach for Salmon Habitat

摘要

This report is divided into five main sections. The first, An Assessment Approach for Habitat Recovery Planning, presents a conceptual framework for understanding relationships among land uses, watershed functions, habitat conditions, and biota. The framework relies on principles of watershed and ecosystem management and organizes the habitat-related questions that each recovery plan should attempt to answer. The second, Analyses for Phase I Recovery Planning: Setting Recovery Goals, discusses assessments that help identify important habitat losses and set recovery goals. The third, Analyses for Phase II Recovery Planning: Identifying Ecosystem Restoration Actions, presents more detailed assessments to conduct within individual watersheds for identifying causes of habitat loss or degradation. How to use Phase I and Phase II information together to help prioritize actions is addressed in the next section, Prioritizing Potential Restoration Actions within Watersheds. Finally, Managing Uncertainty in Habitat Recovery Planning discusses how uncertainty can affect planning decisions and provides guidance and examples for identifying and quantifying types of uncertainty. This document also includes three appendices. The following is a summary of these sections.
