Key challenges and developments in wildlife ecological risk assessment: Problem formulation.

Area of Science:

• Environmental toxicology
• Ecological risk assessment
• Chemical safety evaluation

Background:

• Problem formulation (PF) is crucial for wildlife risk assessments, informing pesticide registration and chemical evaluations.
• Despite scientific advances, risk assessments rarely incorporate population- and system-level ecological processes.
• Existing methods have not been fully integrated into wildlife risk assessment practices.

Purpose of the Study:

• To identify opportunities for improving wildlife risk assessments by enhancing the problem formulation stage.
• To promote the use of population- and system-level endpoints in risk assessment.
• To align risk assessment practices with established guidance for robust conceptual models and decision planning.

Main Methods:

• Focusing on conceptual model construction within the problem formulation stage.
• Selecting assessment endpoints that target population- and system-level processes.
• Adhering to established risk assessment guidance, including clear protection goals and stakeholder engagement.

Main Results:

• Opportunities exist to elevate wildlife risk assessments by refining the problem formulation process.
• Integrating population- and system-level thinking can enhance the predictive power of assessments.
• The four established steps of risk assessment guidance provide a framework for improvement.

Conclusions:

• Elevating the problem formulation stage, particularly conceptual models and endpoint selection, is key to advancing wildlife risk assessment.
• Incorporating population- and system-level processes will lead to more relevant and predictive environmental risk evaluations.
• Consistent application of established guidance, including stakeholder engagement and iterative planning, is essential for robust risk assessment.
