Figure 1. Proposed hierarchical framework for assessing and reporting on ecosystem condition in Puget Sound.

Goals combine societal values and scientific understanding to define a desired ecosystem condition [13], [14]. Focal components divide a goal into its major ecological characteristics. Key attributes are characteristics that describe the state of a focal component. Indicators are metrics that reflect the structure, composition, or functioning of an ecological system and can assess changes in key attributes [14], [45]. Adapted from U.S. EPA [14].
