Definition of Indicator species:
A species whose presence or absence indicates a certain environmental condition or a particular community or habitat.
This is the common definition for Indicator species, other definitions can be discussed in the article


Examples

  • Greasewood indicates saline soil;
  • Mosses often indicate acid soil;
  • Tubifex worms indicate oxygen-poor and stagnant water unfit to drink;
  • Ammophila arenaria requires blown sand to thrive and will begin to die back if sheltered from further accommodation. Thus it is a good indicator of sediment supply to the system[1].

[Comment: The last example can be confusing; A. arenaria also occurs on retreating coasts.]
