There are most likely more than just these few species of aglae living in Girraween. Many algae are single-celled organisms, too tiny to see with the naked eye. Even though they can be so very small, algae play a very important role in the park.

Water-living algae, such as the blue-green algae pictured below, produce oxygen and provide food for the many creatures that live in Girraween's creeks. Other algae that grow on bare rock, such as the red-coloured algae pictured below, break down the granite into soils that other plants can thrive in. [For more, see Biological Weathering.]

Blue-green algae are actually not plants but bacteria. Like plants, however, they create their own food using light and produce oxygen (photosynthesize).

Some algae (green and blue-green algae) have formed a symbiotic relationship with various fungi, creating the composite organisms that we know as lichens.
