在农业景观中，树篱和树木线等线性特征为许多物种提供了宝贵的栖息地。我们使用的数据从315个断面，完成了蝙蝠分布的全国声学调查的一部分，研究在农村地区的线性功能附近的四种蝙蝠的发病率。线性特征的使用进行了评估，绿篱宽度，树木密度，存在的水和林地接近。为了研究树木密度的影响，线性特征被分类为没有树木的树篱，稀疏树木的树篱（包括50%的树冠）。对线性特征的使用不受树木密度的影响;所有类型的线性特征都与P. pipistrellus发病率的类似增加相关。使用线性功能的Pipistrellus pygmaeus是依赖于树木密度和林地的接近度;只有线性功能包含树木提供了增加P. pygmaeus发病率，而不管林地的接近度。P. pipistrellus和P. pygmaeus的发病率不受绿篱宽度或水的存在的影响。任何类型的线性特征的密度的发生率的Nyctalus tubula和Eptesicus tubinus不受影响。许多农业环境计划为建造和管理树篱提供财政奖励。优化线性特征提供的生物多样性增益将最大限度地提高这些方案的有效性。农业环境措施，鼓励提供和保留树篱树木将有利于蝙蝠在农业景观。(C)2011爱思唯尔有限公司保留所有权利。
Within agricultural landscapes, linear features such as hedgerows and tree-lines provide valuable habitat for many species. We use data from 315 transects, completed as part of a national acoustic survey of bat distribution, to examine the incidence of four bat species adjacent to linear features in rural areas. The use of linear features was assessed in relation to hedgerow width, tree density, the presence of water and woodland proximity. To examine the effect of tree density, linear features were classified as either hedgerows without trees, hedgerows with sparse trees (comprising 50% tree canopy). The use of linear features by Pipistrellus pipstrellus was not affected by tree density; linear features of all types were associated with a similar increase in P. pipistrellus incidence. The use of linear features by Pipistrellus pygmaeus was dependent on both tree density and the proximity of woodland; only linear features containing trees provided an increase in P. pygmaeus incidence regardless of woodland proximity. P. pipistrellus and P. pygmaeus incidence was not affected by hedgerow width or the presence of water. Incidence of Nyctalus noctula and Eptesicus serotinus was unaffected by the density of linear features of any type. Many agri-environment schemes offer financial incentives for the creation and management of hedgerows. Optimising the biodiversity gain provided by linear features will maximise the effectiveness of these schemes. Agri-environment measures that encourage the provision and retention of hedgerow trees will benefit bats in agricultural landscapes. (C) 2011 Elsevier Ltd. All rights reserved.
