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.]
