由于长期砍伐森林，英国的林地覆盖面积急剧减少。剩下的林地主要是农田内高度破碎的小片林地。一些农业环境计划旨在增加农业用地上林地的数量和质量，但是关于飞蛾与林地特征之间的关系的信息有限，这些信息可用于为林地的创造和管理提出实际建议。通过对农田内林地斑块中微蛾和大蛾群落的研究，评价林地植被特征和斑块形态的影响。此外，我们还测量了周围景观的影响，以评估景观尺度管理方法对蛾类保护的潜在重要性。一般来说，高的树种多样性和高的本地树种比例与较高的蛾度和物种丰富度有关；放牧也有负面影响。在靠近其他林地的大型林地斑块中，飞蛾的丰度和丰富度较高。形状紧凑的林地（边缘暴露于周围基质的比例较小）有更多的“林地物种”，这些物种与林地核心栖息地有关。小片林地可以保持相对较高的蛾类丰度和丰富度，这取决于它们的形状和与其他林地的接近程度。林地程度是影响飞蛾最重要的景观参数，且主要在相对较小的空间尺度上(
As a consequence of long-term deforestation, woodland cover has been drastically reduced in the United Kingdom. The remaining woodland consists mainly of small, highly fragmented woodland patches within farmland. A number of agri-environment schemes aim to increase the amount and quality of woodland on agricultural land, but there is limited information on associations between moths and woodland characteristics which can be used to produce practical recommendations for woodland creation and management. We studied micro- and macromoth communities in woodland patches within farmland to assess the effects of woodland vegetation character and patch configuration. In addition, we measured the influence of the surrounding landscape to assess the potential importance of a landscape-scale management approach for moth conservation. In general, high tree species diversity and a high proportion of native tree species were related to higher moth abundance and species richness; there was a negative impact of grazing. Moth abundance and richness were higher in large woodland patches located close to other woodlands. Woodlands of compact shapes (with proportionally less edge exposed to the surrounding matrix) had higher numbers of 'woodland species', which were associated with woodland core habitat. Small woodland patches can potentially maintain relatively high moth abundance and richness, depending on their shape and proximity to other woodlands. Woodland extent was the most important landscape parameter influencing moths, mostly at relatively small spatial scales (
