Support UK seagrass restoration and research

Why support seagrass restoration and research in the UK?

Seagrasses are marine flowering plants that thrive in shallow waters across the globe, forming dense meadows that provide shelter and habitat to thousands of marine species. They act as nurseries, with the leafy underwater canopy they create providing shelter for small invertebrates (like crabs and shrimp and other types of crustaceans), small fish and juveniles of larger fish species. These vibrant biodiverse meadows also act as feeding grounds for larger predators that utilise the seagrass meadows to hunt for food.  

 The leaves of seagrass can also filter pathogens, bacteria, and pollution out of seawater, making our oceans a cleaner and safer environment to enjoy. 

Furthermore, the roots of seagrass extend through the sediment creating a network which strengthens the coast, helping to reduce coastal erosion. Their leaves also weaken wave energy and storm surges offering protection to coastal communities from storms.

Seagrass meadows have the potential to sequester and store large quantities of the carbon dissolved in our ocean, often known as ‘blue carbon’. Whilst seagrass occupies only 0.1% of the seafloor, they are responsible for up to 18% of the organic carbon buried in the ocean.

The UK’s seagrass habitats play an important role for both biodiversity and carbon storage. However research estimates that up to 92% of the UK’s seagrass has been lost since 1936, and we must act now to restore these important ecosystems. Mapping existing seagrass meadows, promoting measures such as sustainable boating practices to conserve our remaining meadows, researching how best to restore them, and replanting seagrass are all important steps you will help to fund through this project.

Benefits

Seagrass meadows have an important role to play in both climate change mitigation and adaptation. These ecosystems are going to be increasingly crucial in our fight to minimise the extent and impact of climate change globally.

Seagrass meadows are able to store carbon in their sediment, essentially ‘locking’ away large amounts of carbon and acting as a carbon store. If undisturbed, this carbon can be stored for millennia. When seagrass meadows are destroyed, the carbon that they have stored for potentially thousands of years is suddenly released back into the ocean and can become a significant carbon source.

How does this project support the UN SDGs?

This project supports a huge 16 of the 17 UN Sustainable Development Goals, demonstrating its wide-ranging and far-reaching impacts.

Seagrass ecosystem provide services for poverty alleviation, making them important for living, subsistence, and livelihoods)

Seagrass ecosystems protect subsistence fisheries which reduces hunger.

Seagrass bioengineers its environment, making it more productive and increasing the nutritional value of fish that are found there.

Seagrass ecosystems provide a means of teaching children core scientific principles, such as photosynthesis and environmental values.

The project helps to empower women in seagrass fisheries, increasing access to food and income for women.

Healthy seagrass filters and cleans water.

Seagrass restoration can be embedded in marine renewable energy.

Sustainable seagrass fisheries and green restoration jobs promote seagrass.

There is a fantastic opportunity for using seagrass as a trailblazer for the uptake of net gain within industrial marine biodiversity loss.

Management of seagrasses and their fisheries supports the underappreciated role of women in these activities.

Old coastal urban heritage infrastructure (e.g., ports) creates opportunities for seagrass restoration.

Seagrass conservation requires sustainable management of associated resources.

Seagrass meadows store and sequester carbon.

Seagrasses bioengineer the seabed, enhancing life and biodiversity underwater.

Seagrasses support coastal defense, provide trophic subsidy to the coast, and support coastal avifauna.

Improved seagrass conservation and restoration activity requires strong cross-sectoral partnerships.
