2. 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.

3. 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

4. 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

5. 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

6. 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.
