On the uplands of Exmoor drainage ditches have been dug across the moorland for a variety of reasons and over many decades.

Generations of peat-cutting and the creation of drainage ditches has caused the mires to dry out, which reduces the water-holding capacity of the moors.

In addition, this drying action causes oxidation of exposed peat bogs which releases large quantities of carbon into the atmosphere. A 'healthy' bog accumulates carbon and absorbs CO2 from the atmosphere.

The focus of the Exmoor Mires Project is to block drainage ditches using sustainable methods, local materials and local contractors in order to 're-wet' the bog, enabling it to retain water and carbon.

During periods of heavy rainfall, re-wetted peat bogs slow down the run-off of water from land before steadily releasing it. This increased water storage has the effect of reducing the fluctuation of river flows, making flooding less likely, reducing soil erosion and the amount of silt entering rivers.

Water carrying less silt is up to 20 per cent less expensive to treat, requiring fewer chemicals and carbon to turn it into our top quality tap water.


Previous Projects
 
Ditch-blocking and water management techniques on Exmoor began in 1998.
What's happening now
 
2000ha is the target area of moorland to be restored on Exmoor.
Benefits
 
Worldwide peatlands are huge carbon stores, but damaged areas release carbon dioxide into the atmosphere through oxidation processes.
History of peat
 
On Exmoor a blanket of peat which is over a metre deep in places covers the central moorland.
Threats to Exmoor's blanket bog
 
Historic environment
 
Exmoors mires are an important repository of archaeological information for a number of reasons.
Research
 
The project has also been asked by Ofwat to undertake research and monitoring on the hydrological and ecological effects of rewetting peatland.
