Wetlands are the superheroes of the natural world. They are crammed with wildlife, protect our coastlines, keep our rivers clean, and store climate-changing amounts of carbon.
Yet through much of history they have been at best ignored and at worst vilified and destroyed. In recent years public campaigns and money have been thrown at tree planting and reforestation, yet hardly a mention was given to restoring the UKās bogs, swamps and marshes. But a quick scan through famous literature, paintings and even films and TV series will show you how often wetlands feature as the unpleasant, sinister backdrop of dark storylines.
Fortunately, things are now changing. This was highlighted with the recent announcement of a 15,000-acre . This is the UKās second so-called āsuper reserveā after Purbeck Heaths in Dorset. These reserves take in a mosaic of different habitats, and by linking them all together as part of an entire landscape management plan, it is hoped the region as a whole will benefit.
In this case, the new super reserve will encompass existing reserves on Somersetās levels and moors, a region of coastal plains, fens, reedbeds and saltmarshes, which make up the heart of the county.
These areas are estimated to contain around 11 million tonnes of carbon, in the form of peat: semi-decomposed dead plant material. When peatlands dry out ā perhaps because they are drained to make farmland or when peat is extracted for compost ā the vegetation decomposes a lot faster, releasing carbon into the atmosphere.
Much of Somersetās peat deposits have been damaged over the centuries, and continue to be so, releasing every year. Their protection as carbon sequestering powerhouses is essential if the UK is to hit its net zero goals in the coming decades.
The saltmarshes on the edge of the new reserve are also carbon-dense habitats and can protect the coastline during storms and sea level rises. Then there is the wildlife that teems in this area, from otters and kingfishers to eels and marsh fritillaries (one of Britainās ).
Well-preserved history
Itās not just the environmental and natural benefits provided by the wetlands of the new super reserve that make the project so special.
Britainās history and heritage is tied up in this area and the acidic, waterlogged peatland conditions means it is uniquely preserved for us to discover. For instance the UKās oldest wooden walkway, the Sweet Track, was built 6,000 years ago to help Neolithic people cross the marshes. Since it was uncovered it has helped archaeologists understand how these people lived.
It may also only be a touch melodramatic to state that England as we know it would not exist if it hadnāt been for the Somerset levels and moors āfen-fastnessā (as described in the ), offering King Alfred the refuge and battleground his small force needed when fighting the Vikings in the 800s. (Though whether he burnt some cakes in the process is up for ).
Large-scale protection
Itās not just the Somerset region that will see the benefits of the proposed landscape-scale management plans ā the entire country will be richer. Of course, some of the area is already under the supervision of conservation organisations and they are doing a great job. But this project goes beyond those individual sites and brings them all together on a larger scale.
Properly managed individual nature reserves, no matter what the size, can be fantastic. But itās when we join-up these pockets and expand them that we can really start to control waterflows, maximise biodiversity, reduce carbon emissions and enhance our own wellbeing. Indeed, research is showing itās at this scale that we can have a and harness the potential of ānature-based solutionsā which allow natural ecosystems to help address the climate and biodiversity crisis.
When these areas are large enough and dominated by coastal and freshwater wetlands then the benefits are magnified, as itās not just a landscape-scale being looked at, or even the seascape, but the āwholescapeā.
This āwholescapeā approach must be the way forward if we are serious about the use of nature-based solutions this century. And natureās superheroes ā our wetlands ā need super nature reserves like the one in Somerset to show us just what they can do.
