The RSPB has been reviewing the state of the UK’s coastal habitats through their Sustainable Shores project. Nathan Richardson from the RSPB describes the headline findings and recommendations from this major project below.
The UK’s estuaries and coasts are incredibly valuable as a place to live, work, relax and play and for the wealth of wildlife they support. They help protect us from flooding; they lock away carbon; they support our fisheries and they attract millions of visitors. The value of the services provided by our coastal habitats is estimated at £48 billion.
However, the coastal zone is in trouble. It is shrinking, and what habitat that remains is generally in a woeful condition. A 2013 assessment of the UK’s internationally important coastal habitats found that none of them have a favourable conservation status.
Stronger nature legislation, in particular the EU Nature Directives, has helped stem the tide of losses due to development. However, our coastal habitats remain very vulnerable to climate change and sea level rise. As sea levels rise in response to global warming, intertidal habitats like mudflat sand saltmarshes can get squeezed against fixed flood defences ("coastal squeeze"). The latest predictions see us continuing to lose at least 60 hectares (ha) of intertidal habitat.
Fortunately, the solutions are in our hands. Through more than 70 projects in the last 25 years we have developed experience of creating coastal habitat. More than 2,500ha of habitat, such as intertidal saltmarshes and mudflats, has been created through techniques such as managed realignment.
The RSPB, working with a range of partners including the Environment Agency, has been at the heart of this effort, helping to deliver and manage more than 33% of the coastal habitat created in the UK (some 880ha). As our experience has increased, our projects have become larger, with schemes such as Medmerry and the Wallasea Island Wild Coast Project providing landscape-scale benefits for wildlife and people.
As part of our Sustainable Shores project, we know that there are more than enough places around the coast where we can replace what has been lost and will be lost in the future. We know what we need to do, where to do it, why and how. But we still haven’t got close to replacing even 25% of the UK area of coastal habitat that has been lost since 1945, and we are struggling to keep up with what continues to be lost each year.

Crucially, the UK is also failing to implement its Shoreline Management Plan policies and to adapt our coast to climate change. This failure was highlighted in the Government’s UK Climate Change Risk Assessment 2017, in which flooding and coastal change risks to infrastructure, communities and businesses was identified as a top risk for the UK.
The RSPB will continue to work with partners to deliver schemes and manage sites that work for people and wildlife. Crucially, we believe there also needs to be:
