Labrador Park is the only Rocky Shore habitat in Singapore. Students often come here to study this unique and “rare” habitat(: Here is some information on the ecology of rocky shores
Ecology of Rocky Shore
Rocky Shore Zonation
There are generally 4 zones on rocky shore: Splash Zone, Upper Shore, Middle Shore and Lower Shore.
The splash zone is the highest part of the rocky shore, it only receives occasional splashes of seawater when the tide is unusually high. Thus, the organisms found here tend to be more terrestial, e.g. Lichens. Organisms found here can also survive without seawater.
The upper shore is mostly covered only during extremely high tides (spring tides), thus it is usually exposed. There is little bio diversity here, and the organisms found here have special adaptations to prevent drying out and are able to cope with severe water loss.
The middle shore is around mean sea level, and is submerged for roughly half a day for each day. It has more bio diversity than the upper shore and splash zone.
The lower shore is covered for most of the day, exposed only during extremely low tides (spring tides). The organisms here are exposed to little sunlight, and are more marine than those found at the splash zone.
This is a very general overview of rocky shore zonation. The organisms found at each zone differ at different places and we apologise for not having much information on organisms found at the rocky shore at Labrador Park as we have not had time to explore much.
However, seagrasses do NOT grow in rocky shore habitats! As they are angiosperms(having roots and vascular system), their roots need to be firmly planted in soil.
Where does seagrass grow?
Seagrasses tend to grow in sandy and muddy areas that generally have no rocks, coastal marine and estuarine habitats, and in sheltered and shallow areas where they are protected from the current and wave action
