Seagrass and saltmarsh habitat expansion

New maps revealing the extent of seagrass and saltmarsh habitats go live.
New mapping tools from the Environment Agency and Natural England which reveal the extent of seagrass and saltmarsh habitats around England for the first time, are now live.
The maps will provide valuable information for the management of these crucial blue carbon habitats, helping to drive forward restoration projects.
Saltmarsh and seagrass habitats are vital to support ocean recovery and fight the impacts of climate change by protecting important marine biodiversity and capturing and storing carbon. They provide a wealth of benefits for people and wildlife, including acting as a flood defence, improving water quality, and providing a place for recreation. They are also key habitats for breeding and feeding birds, many of them migratory, as well as nursery sites for a range of commercial fish and marine invertebrate species.
To help protect and expand these habitats, the Environment Agency recently published its saltmarsh inventory and accompanying report, mapping where saltmarsh has been gained and lost over a ten year period. The data revealed a 7% increase in saltmarsh extent around the English coast. This takes the total habitat to over 350km squared, with saltmarsh restoration projects contributing 37% of this gain.
A brand new national seagrass map has also been published by Natural England and the Environment which identifies where intertidal and subtidal seagrass habitats have been surveyed in England and draws on historic data to reveal how seagrass extent has changed over time.
Roger Proudfoot, Estuaries and Coasts Planning Manager at the Environment Agency, said:
These new maps help us understand the threats to these important habitats, providing a baseline for seagrass and showing how saltmarshes are changing which helps inform us on actions we can take to protect and restore them.
Both saltmarsh and seagrass are an important part of the Environment Agency’s work to tackle climate change and the biodiversity crisis; improve water quality; and in promoting green growth for a sustainable future.
A number of coastal habitat restoration schemes are already underway, including the LIFE Recreation ReMEDIES project led by Natural England, the largest seagrass restoration project in England which is restoring seagrass in Plymouth Sound and the Solent.
Jonathan Burney, Director of Strategy & Government Advice (Marine) at Natural England, said:
Seagrasses are a vital part of our marine ecosystem and bring a range of benefits for people and nature, including providing an important habitat for wildlife, enhancing water quality and capturing and storing carbon”.
We are undertaking England’s largest seagrass planting project to restore our precious marine environment, and this new map will be a pivotal tool to progress more seagrass restoration projects around the UK”.
Elsewhere, the Natural Environment Investment Readiness Fund, coordinated by the Environment Agency, is supporting three restoration projects with the aim of enabling them to attract private sector funding. These include the Biosphere Foundation, who are aiming to deliver saltmarsh restoration using finance raised from carbon credit sales, and Plymouth City Council who are developing a develop a pilot seagrass carbon code to attract investment. Saltmarsh and seagrass are also two of the estuarine and coastal habitats being prioritised by the Restoring Meadow, Marsh and Reef (ReMeMaRe) habitat restoration initiative.
The maps follow the publication of two free handbooks providing practical advice to local authorities, community partnerships and environmental organisations on restoring and creating estuarine and coastal habitats.
