Bioindicators

Abstract

A biological indicator is a species (or group of species) that readily reflects some aspect of the state of the environment within which it is found. Bioindicators are used to detect or demonstrate the existence of a particular environmental state, and to monitor changes in that state. In this way they are used as tools to extract abiotic or biotic information from the environment so that this information can be used for making scientifically based management and policy decisions.
