Peatland drainage in Scotland has been carried out for over a century, to prepare peatland for afforestation, agricultural or grouse moorland use. Drainage leads to peatland degradation and carbon release, in the form of Greenhouse Gas (GHG) emissions and the release of carbon into waterways. There are few records remaining of where drainage has taken place in Scotland, although this information is vital to enable accurate emissions accounting in the UK GHG Inventory and to assess priority areas to fulfil the ambitious peatland restoration and rewetting targets in the Climate Change Plan.
