This site is about Labrador Park and the seagrass ecosystem at the beach. We are a group of students monitoring the seagrasses there, namely Halophila ovalis, Thalassia hemprichii, and Enhalus acoroides. And yes, there ARE seagrasses there.
Seagrasses are ANGIOSPERMS(flowering plants) and NOT seaweed or algae. Similar to their counterparts on land, they thrive better in tropical climates than temperate ones. There are 11 species of seagrasses in Singapore and they can be mostly found at Chek Jawa, west of Pulau Semakau, Labrador Beach, Cyrene reefs and Tuas.
