Macroinvertebrates

This simulates the collection of macroinvertebrates in waterways. To collect, click on the "Click here to collect macroinvertebrates" area. Each time this area is clicked a new grouping of macroinvertebrate will be collected. This can be used to calculate biodiversity or to perform a river quality analysis. Below is a key identifying the organisms as pollution sensitive, somewhat pollution tolerant, or pollution tolerant. Two different rivers are available for analysis.

Group I: Pollution Sensitive Group II: Somewhat Pollution Tolerant Group III: Pollution Tolerant
