| Introduction | Identification Key |



Biomonitoring is the use of organisms to assess or monitor environmental conditions. Benthic macroinvertebrates are ideal for use in biomonitoring for several reasons:
  1. They are ubiquitous.
  2. They are relatively sedentary and long-lived.
  3. Some species of benthic macroinvertebrates are sensitive to pollution and some are tolerant.
  4. Benthic macroinvertebrates are easy to collect and identify.
Benthic macroinvertebrates act as continuous monitors of the water they live in. Unlike chemical monitoring, which provides information about water quality at the time of measurement, biological monitoring can provide information about past and/or episodic pollution.
