Planning Pacific Salmon and Steelhead Reintroductions Aimed at Long-Term Viability and Recovery

摘要: AbstractLocal extirpations of Pacific salmon Oncorhynchus spp. and steelhead O. mykiss, often due to dams other stream barriers, are common throughout the western United States. Reestablishing salmonid populations in areas they historically occupied has substantial potential assist conservation efforts, but best practices for reintroduction not well established. In this paper, we present a framework planning reintroductions designed promote recovery salmonids listed under Endangered Species Act. Before implementing plan, managers should first describe benefits, risks, constraints proposed reintroduction. We define benefits as specific biological improvements towards objectives. Risks negative outcomes that could worsen status rather than improve it. Constraints factors will determine whether successfully establishes self-sustaining population. provide guidance ...
