What are ecological indicators?

An ecological indicator is a plant or animal species that can be used to indicate a changes in an ecosystem, generally changes that can affect ecosystem health. The indicators react to natural or anthropogenic effects. They may indicate the presence of air, water, or soil pollution, as well as changes in climate, moisture, and species composition.

They can be the "canary" equivalent for ecosystems. They can be used to obtain indicator values of various parameters simply due to the presence of a population.
