Saving seagrass means saving our seas

Seagrasses are flowering plants that live in shallow sheltered areas along our coast. These sensitive plants are different from seaweed and form bright green leaves. These leaves form large, dense meadows under the sea. Like the coral reefs and rainforest’s of the tropics, these underwater gardens are full of life, hosting many animals of different shapes, colours and sizes. However, like rainforest’s and coral reefs, these incredible underwater gardens are threatened. Globally, estimates suggest we lose an area of seagrass around the same size as two football pitches every hour. Protecting what is left is vital.

Although it might not look like it, seagrass is incredibly important around our coasts, for people, biodiversity and the planet

Here are just some reasons why:

Seagrass meadows act as a natural sea defence by trapping sediment and slowing down currents and waves.
They provide a home for many baby fish, including Cod, Plaice and Pollack around our shores.
Seagrass meadows absorb and store large amounts of carbon and are vital in the fight against climate change.
They absorb nutrients, pollutants and bacteria and help to keep our coastal waters clean

Seagrass under threat!

Despite its importance, seagrass is disappearing...Fast.

Storms, disease and human induced threats such as pollution and decreased water clarity, often triggered by excessive nutrients and sediments in runoff from the land, can have devastating local effects. Physical damage can also occur from contact with boat propellers and from chain moorings. Generally, if only leaves and above-ground vegetation are impacted, seagrasses can recover from direct physical damage within a few weeks; however, when damage is done to roots and rhizomes, the ability of the plant to produce new growth is severely impacted, and plants may never be able to recover.
