Metric 4

Number of Intolerant Species


This metric provides a measure of fish species most sensitive to environmental degradation.

The absence of some fish species occurs with subtle environmental changes caused by

anthropogenic disturbances. Fish species assigned as intolerant should have historical

distributions significantly greater than presently occuring populations and be restricted to

streams that have exceptional water quality (Karr et al. 1986).
