Whether tributary habitat improvements have achieved, or are likely to achieve, the goal of recovering conditions favoring the natural production of native salmonids in the Columbia River Basin is an open question, and a review of the approaches, assessment procedures, and implementation strategies for habitat improvement is therefore timely. In this report, the ISAB examines several topics central to the recovery of tributary habitat:
- the biological objectives related to habitat recovery,
- the strategies for implementing restoration,
- the incentives for implementing restoration,
- the scientific foundation for habitat recovery, and
- monitoring and evaluation.
The objective of the review is to answer the question: What concepts and strategies should be incorporated in habitat recovery actions to improve their chances for success?
