为管理栖息地而焚烧是全球普遍的做法。由于对气候变化的潜在贡献，在富碳土壤上燃烧是一个全球环境问题。在英国，高地石南和毯子沼泽，所谓的“高沼地”，通常覆盖在富含碳的土壤上，具有国际重要的保护价值，但被烧毁作为狩猎鸟射击和牲畜放牧的管理。关于英国各地燃烧的空间范围或时间趋势的详细信息很少。这阻碍了可持续管理政策的制定，因为这种做法可能对土壤碳储存、水质和生境条件有害。利用遥感数据，我们绘制了英国45000公里（2）范围内的猎鸟管理燃烧图。燃烧发生在8551 1公里的广场，在苏格兰和英格兰被烧毁的广场三分之一的泥炭深度>= 0.5米，和广场内燃烧的高沼地的比例在泥炭深度达到峰值1-2米。在55%的特别保护区和63%的特别保护区进行了评估，发现燃烧，燃烧的高沼地的比例显着高于保护区外的可比广场内的网站。从2001年到2011年，无论泥炭深度如何，每年的烧伤数量都在增加。燃烧与泥炭和保护区的空间重叠，越来越多的烧伤需要迫切关注，可持续管理和扭转在英国高地生态系统服务的损害的政策的发展。(C)2015爱思唯尔有限公司版权所有。
Burning for habitat management is globally widespread. Burning over carbon-rich soils is a global environmental concern due to the potential contribution to climate change. In the UK upland heath and blanket bog, so-called 'moorland', often overlies carbon-rich soils, and has internationally important conservation value, but is burned as management for gamebird shooting and to a lesser extent for livestock grazing. There is little detailed information on the spatial extent or temporal trends in burning across the UK. This hinders formulation of policies for sustainable management, given that the practice is potentially detrimental for soil carbon storage, water quality and habitat condition. Using remotely sensed data, we mapped burning for gamebird management across c45 000 km(2) of the UK. Burning occurred across 8551 1-km squares, a third of the burned squares in Scotland and England were on peat >= 0.5 m in depth, and the proportion of moorland burned within squares peaked at peat depths of 1-2 m. Burning was detected within 55% of Special Areas of Conservation and 63% of Special Protection Areas that were assessed, and the proportion of moorland burned was significantly higher inside sites than on comparable squares outside protected areas. The annual numbers Of burns increased from 2001 to 2011 irrespective of peat depth. The spatial overlap of burning with peat and protected areas and the increasing number of burns require urgent attention, for the development of policies for sustainable management and reversal of damage to ecosystem services in the UK uplands.
