1. 在世界范围内，控制用火是重要的生态管理工具，对于许多社区的延续至关重要。它在英格兰高地地区被广泛使用，以维持矮灌木栖息地以饲养猎鸟。然而，不适当的焚烧现在被认为是这些地区保护区状况不佳的第二重要原因。尽管如此，关于其使用程度和频率的数据却很少，无法帮助判断其对生物多样性的潜在影响。2．这项研究利用航空摄影对英国高地2%的样本（208公里(2)）进行了首次调查，调查了全国火灾管理规模，并利用历史摄影来确定其使用的中期趋势。3．英国高地的管理焚烧现在在以杜鹃花为主的荒原上很普遍； 2000年，该栖息地17%的面积在过去4年内被烧毁，相当于114平方公里(2)年(-1)。目前，一致管理的站点的中位燃烧重复时间约为 20 年。4。在此期间，大多数英国国家公园内新烧伤的范围显着增加（从 15.1% 增加到 29.7%），表明某些地区的烧伤情况有所加剧。5。合成与应用。燃烧的程度和频率，以及进行这种管理的栖息地，都是有争议的问题。协调保护、狩猎和农业利益相关者的不同目标，以便制定战略和地方管理规划来解决这些问题，需要有关燃烧做法的范围和历史的信息。这项研究提供了急需的对英格兰燃烧做法的首次全国性估计，并作为判断管理制度变化及其对栖息地影响的基线。
1. World-wide, the controlled use of fire is an important ecological management tool and is essential for the continuance of many communities. It is used extensively in upland regions of England to maintain dwarf shrub habitats for game-bird rearing. Inappropriate burning, however, is now cited as the second most important reason for the poor condition of conservation sites in these areas. Despite this there are few data on the extent and frequency of its use to help judge its potential impact on biodiversity.2. This study, using aerial photography of a 2% sample (208 km(2)) of the English uplands, surveyed the national scale of fire management for the first time, and used historical photography to identify medium-term trends in its use.3. Management burning in the English uplands is now widespread on ericaceous-dominated moorland; in the year 2000 17% of the area of this habitat had been burned within the previous 4 years, equivalent to 114 km(2) year(-1). The present median burn repeat time of consistently managed sites is approximately 20 years.4. Within most of the English national parks there has been a significant increase in the extent of new burns (from 15.1% to 29.7%) over this period, indicating an intensification of burning regimes in some areas.5. Synthesis and applications. The extent and frequency of burning, and the habitats in which this management occurs, are contentious issues. Reconciling the differing objectives of conservation, game rearing and agricultural stakeholders to allow the development of both strategic and local management planning to address these issues requires information on the extent and history of burning practices. This study provides a much needed first national estimate of burning practices in England and serves as a baseline against which changes in management regimes and their impacts on habitats can be judged.
