Intertidal Walk Introduction - About the Intertidal Zone - Safety - Equipment

Intertidal Zone There are different types of reefs. The reef around North Keppel Island is a fringing reef We are in a green zone, which means that it is a ‘no take’ zone. This allows the area to regenerate.

Factors affecting the intertidal zone * The intertidal zone is subject to tides and the associated physical and biological stresses of being covered with water and then exposed to air. * The organisms living in the intertidal zone have adaptations to aid survival in their particular habitat. Abiotic (non-living) factors - pH - amount of light - salinity - slope - turbidity, current - wind speed - temperature

Life in the intertidal zone There is an amazing and diverse range of plant and animal organisms in the intertidal zone You might see tube worms, sea slugs, soft corals, mudskippers, algae If you move a rock, it must be put back exactly as it was to protect the life underneath the rock

Safety There are dangerous organisms in the reef. General rule – If you are not sure, then don’t touch it! Beware of cone shells and a specific few corals that can sting Beware of oysters on the rocks, and stay away from them as much as possible Stay together as a group and follow teacher instructions

Take care of this beautiful area Be gentle with any animals that you might touch such as sea slugs Stay on the sand patches as much as possible We will be making an impact just by walking, so try and make that impact as minimal as possible.
