Value resulting from the data reduction of Metrics across sites and temporal periods based on applying the procedures in the Inference Design. A reported value used to indicate the status, condition, or trend of a resource or ecological process; intended to answer questions posed by the Objectives of the Protocol. Contrast with Metric.
Metric J + Metric K = Indicator X

For example, measurement of channel migration (metric) + over a period of time (metric) = Channel Migration Rate (indicator)

Per the Inference Design, Metrics are combined or reduced to produce Indicators.
