Vulnerabilities

Moorland fires

Kersey et al. (1) reported on the risk of moorland fires in the East Midlands. An increased risk of moorland fires arising from climate change is a major issue for the Peak District. Such fires could lead to the replacement of heather moorland by grass, with serious implications for soil erosion and grouse-shooting. There have been 30 to 40 fires on the National Trust estate in the High Peak in the past decade – about a dozen of which have been classified as ‘major’ fires. Approximately one third of fires are caused by visitors’ cigarettes, whilst another third are heather management fires that have gone out of control (1).


Fires have a direct impact upon plant communities. An even greater problem is when fires get down into the peat causing large areas of erosion which are very difficult to re-vegetate, and which add to water colouration and associated treatment problems (1).

The Peak District National Park Authority has done much work on educating visitors about the risks and hazards of fire. Work is also proceeding on how to respond more effectively to fires when they do occur. Schemes are also being undertaken in the Peak on how to restore vegetation after fires. The problem of re-vegetation was described by the National Trust, however, as ‘quite immense’ (1).

The impact of climate change on the number of wildfires in the Peak District uplands has been investigated (3). Future climate projections suggest an overall increase in occurrence of summer wildfires in the Peak District uplands. The likelihood of spring wildfires is not reduced by wetter winter conditions. Temperature rise has a non-linear impact, with the risk of wildfire occurrence rising disproportionately with temperature. Recreation use is a major source of ignition. Little change in wildfire incidence is projected in the near future, but as climate change intensifies, the danger of summer wildfires is projected to increase from 2070 (3).

Forest fires

In the UK, between now and 2100, the conditions will change towards a higher risk of forest fires (2).

Adaptation strategies

Adaptation options to forest fire risk should aim to decrease the vulnerability, where a change in tree species from conifers to broadleaves had most effect (2).

Moorlands may have to be managed to reduce the chance of summer wildfires becoming catastrophic, with consequent damage to ecosystem services such as water supplies and peat carbon storage. Management measures may include controlled burning, grazing or mowing to remove fuel (3).
