Seagrass meadows are marine habitats dominated by seagrasses, forming what resembles a flooded grassfield. Seagrasses are the only group of flowering plants that can survive in the marine habitat. They flower and pollinate underwater, and some even produce edible fruits.

Seagrass meadows are important because they serve various functions. Due to their efficiency at trapping sediments, they can prevent erosion. They provide food and shelter for many marine organisms (including large mammals like dugongs) while also serving as nurseries for many juvenile fishes and shrimps. Therefore, they support a very high diversity of marine life.

Though more extensive in the past, seagrass meadows in Singapore now occur in patches. Today, the more extensive meadows can be found in the intertidal flats of Pulau Semakau (about 100 ha), Cyrene Reef (about 60 ha) and Chek Jawa (about 50 ha).Though seagrass meadows are greatly reduced in area, recent surveys have recorded twelve plant species in the seagrass meadows of Singapore, which is more than half of all the known species in the Asia-Pacific.
