Risk assessment for invasive species

Area of Science:

• Ecology
• Environmental Science
• Risk Assessment

Background:

• Invasive species incur substantial economic costs and pose risks to environmental services and public health in the U.S.
• The National Invasive Species Council (NISC) coordinates domestic management efforts, focusing on science-based risk evaluation.
• International agreements, including the WTO's SPS Agreement, emphasize scientific risk assessment for trade regulations.

Purpose of the Study:

• To address the nascent field of invasive species risk assessment.
• To formulate scientifically sound methods and approaches for evaluating invasive species risks.
• To ensure domestic and international risk assessment processes are based on robust scientific principles.

Main Methods:

• A joint workshop was convened by the Society for Risk Analysis Ecological Risk Assessment Specialty Group and the Ecological Society of America Theoretical Ecology Section.
• The workshop aimed to provide independent scientific input for developing risk assessment methodologies.
• Focus on establishing sound scientific principles for risk analysis.

Main Results:

• The field of invasive species risk assessment is currently underdeveloped.
• There is a persistent gap between the demand for empirical evidence and its availability.
• The need for scientifically rigorous methods is paramount.

Conclusions:

• Formulating scientifically sound methods for invasive species risk assessment is an urgent priority.
• Risk assessment processes must be firmly rooted in sound scientific principles.
• Continued development of risk assessment frameworks is essential for managing invasive species effectively.
