Best Practices for Integrating Ecosystem Services into Federal Decision Making

Best Practices for Integrating Ecosystem Services into Federal Decision Making

Federal agencies take many actions that influence ecosystem conditions and change the provision of ecosystem services valued by the public. To date, most decisions affecting ecosystems have relied on ecological assessments with little or no consideration of the value of ecosystem services. Best practice for ecosystem services assessments is to apply quantitative measures and methods that express both an ecosystem’s capacity to provide valued services and, through those services, social benefit (value). Although preference evaluation methods are well established, their implementation can be infeasible because of time or resource constraints, particularly when new data need to be collected. In such cases, the minimum standard recommended for an ecosystem services assessment is to use measures that go beyond narrative description and that are carefully constructed to reflect the ecosystem’s capacity to provide benefits to society but that stop short of a formal assessment of people’s preferences. These measures of ecosystem services are benefit-relevant indicators (BRIs). Their use ensures that ecosystem services assessments measure outcomes that are demonstrably relevant to human welfare, rather than biophysical measures that might not be relevant to human welfare. If ecosystem service values or BRIs are not used in some manner, ecosystem services are not being assessed, and no direct insights can be drawn about effects on social welfare. This minimum best practice is broadly achievable across agencies and decision contexts with current capacity and resources.
