David Ross is correct to highlight the dangers of wildfires to the peat stored in Scotland's uplands, and the evidence of massive damage in the English Peak District over past decades is a warning ("Peat wildfires are linked to climate change", The Herald, September 24).

As our climate changes, wildfires are likely to become more frequent, especially in the spring when there is a lot of dry fuel in the form of dead vegetation after the winter, as we have seen in 2012 and 2013.

Wildfires with high fuel load burn hottest and go down into the peat layer below, resulting in loss of all vegetation and then releasing the carbon stored in the peat through wind and water erosion.

However, periodic reduction of the fuel load by carefully managed muirburn has a big part to play in preventing such wildfires. When done correctly, muirburn will take off excess vegetation, leaving the ground layer intact and encouraging vigorous new growth that protects in turn the peat below. Areas of short vegetation also act as natural firebreaks, which is why wildfires on managed moorland tend to be far less damaging than where a thick layer of old woody heather has been allowed to develop.

Peatlands are increasingly recognised as a vital way of storing carbon and moorland managers are playing an active part in preventing damage to the peat.

Glasgow University researchers suggest peat destroyed by a wildfire on a 10-acre site in the Highlands released between 0.1% and 0.3% of carbon dioxide all the UK's peatlands would otherwise have absorbed in a year. Why, then, does the Scottish Government support the building of wind farms on peatlands? The first phase of the Whitelee site covered 13,000 acres from which one million cubic metres of peat were removed.
