Benthic (meaning “bottom-dwelling”) macroinvertebrates are small aquatic animals and the aquatic larval stages of insects. They include dragonfly and stonefly larvae, snails, worms, and beetles.

Bioassessments involve field sampling of aquatic biological communities to characterize community structure (i.e., diversity, pollution tolerance). They include measuring water quality indicators such as dissolved oxygen, evaluating habitat conditions and determining the health of aquatic insect communities.

The purpose of a biological assessment is to evaluate the potential effects of proposed actions on listed and proposed species and designated and proposed critical habitat and to determine whether any such species or habitat are likely to be adversely affected by the action.

Biological assessments (bioassessments) are a way to evaluate the health of a stream by looking at the overall physical habitat and the organisms that live there.

Rapid Bioassessment Protocols. The Assessment and Watershed Protection Division developed the rapid bioassessment protocols (RBPs) designed to provide basic aquatic life data for water quality management purposes such as problem screening, site ranking, and trend monitoring, and produced a document.

Rapid bioassessment is based on comparing habitat, water quality, and biological measures of a given stream with an expected state, or stream reference condition, that would exist in the same type of stream in the absence of human disturbance.

Biological assessment (bioassessment) is an evaluation of the condition of a waterbody based on the organisms living within it. It involves surveying the types and numbers of organisms present in the water and comparing the results to established benchmarks of biological health.
