Using structured decision making to help implement a precautionary approach to endangered species management.

Area of Science:

• Conservation Biology
• Risk Management
• Environmental Policy

Background:

• Endangered species protection is a critical risk management issue in North America.
• Precautionary approaches are conceptually emphasized but lack applied evaluation frameworks.
• Existing risk management practices often overlook multidimensional impacts of precautionary strategies.

Purpose of the Study:

• To demonstrate how decision-aiding techniques can create and analyze alternative precautionary strategies.
• To apply these techniques to the protection of endangered Cultus Lake salmon.
• To address the challenge of implementing precautionary approaches amidst economic, social, and biological tradeoffs.

Main Methods:

• Utilized a structured decision-making (SDM) process to bound the management problem.
• Defined objectives and performance measures for conservation efforts.
• Developed and evaluated alternative management strategies using tools like strategy tables.

Main Results:

• Decision-aiding techniques facilitated the creation and analysis of alternative precautionary strategies.
• The SDM process helped stakeholders identify and evaluate management options considering tradeoffs.
• Identified areas of agreement and disagreement among multistakeholder committee participants.

Conclusions:

• Structured decision-making provides a practical framework for implementing precautionary approaches in endangered species management.
• Quantitative analysis can aid in defining and applying the precautionary principle in complex conservation scenarios.
• Decision-focused processes have broader implications for other precautionary resource management initiatives.
