Scottish Gamekeepers Association Chairman Alex Hogg said: "It is important to monitor the affects of all management practice on land.
Those clamouring for curbs on grouse shooting, for example, should assess the carbon released through widespread afforestation and pine regeneration programmes on peat soil in the Scottish uplands, which have the same drying and degrading affect as described in the Leeds study, including the release of stored pollutants.
“Controlled heather burning, following the strict Muirburn Code, only takes place within very short, regulated, seasons. Following best practice, it only takes place when the fire will not burn into peat edges.
“Aside from providing benefits acknowledged by SNH and organisations such as RSPB when it comes to conservation for black grouse, for example, controlled muirburn helps alleviate more damaging environmental problems on peatland.
“Rotational strip burning acts as a fire-break against the spread of wildfires which scorch peat over large areas, releasing carbon into the atmosphere at a far more damaging rate than any controlled muirburn would. We saw this at Mar Lodge when a campfire caused the loss of 10 hectares of important blaeberry amongst Pinewoods.
“Regenerating heather, which has lost its nutritional value, through cyclical muirburn provides vital food and shelter for birds such as waders, some of which are now only stable on grouse moors, so it is important to see the study within context.”
