Taxa: RIVPACS score

RIVPACS (River InVertebrate Prediction and Classification System) is a model that predicts probabilities of aquatic invertebrates occurring in streams in Western Washington. The number of observed taxa (O) at a test site is divided by the expected taxa (E), yielding a ratio. A ratio of 1 indicates that all expected taxa are present. As a site becomes more degraded, fewer expected taxa are observed, yielding a smaller ratio. We are 90% confident that a ratio smaller than 0.86 is degraded relative to a reference condition.

Taxa: RIVPACS score

RIVPACS (River InVertebrate Prediction and Classification System) is a model that predicts probabilities of aquatic invertebrates occurring in streams in Western Washington. The number of observed taxa (O) at a test site is divided by the expected taxa (E), yielding a ratio. A ratio of 1 indicates that all expected taxa are present. As a site becomes more degraded, fewer expected taxa are observed, yielding a smaller ratio. We are 90% confident that a ratio smaller than 0.86 is degraded relative to a reference condition.

RIVPACS score for this visit: 1.09
