Index of nonindigenous aquatic animal species is one of a group of measures under the animals indicator -- one or more is required. The animals indicator is under the human-caused change monitoring question for the natural quality.

This measure is reported as a single value. The wilderness was designated in 1978, so we constrain our analysis to observations between 1978 and 2020.

The space below will show something interesting, like a graph or a map, about this measure for this reporting period.
