Like meadows on land, seagrass meadows are highly productive and support extensive food webs. Apart from green turtles, dugong and garfish, very few animals directly eat seagrass. Seagrasses support many important fisheries species, and slow down water movement which helps to stop shorelines and marshes from eroding. For a number of sites detailed survey and monitoring reports also exist. They also help with coastal stability. They also absorb nutrients from coastal run-off and stabilise sediment, helping to keep the water clear. For this reason, seagrass meadows are often referred to as the “prairies of the sea.” Fish visit seagrass meadows to hunt or to hide in between the seagrass leaves. What is it?

Seagrass meadows have a high carbon sequestering rate, with an average of 830 Kg of carbon per hectare per year (3), about 30x higher than terrestrial forests (4). Meadows of seagrass spread across the seabed, their dense green leaves sheltering a wealth of wildlife including our two native species of seahorse.
