Algae in the water and lichen on tree trunks are very abundant here
.Lichens are nature's pioneers...they are among the first to arrive, finding their homes in some of the most barren and inhospitable parts of the world. From there they slowly begin the process of creating a foundation for habitation by others.
The structure of lichens are unique: a symbioses of two organisms -- a fungus and algae -- so complete that they behave and look like an entirely new being. A lichen can literally eat stones, survive severe cold, and remain dormant for long periods without harm.
