摘要:灌木树篱是英国景观之一,为一些群体提供食物和住所,是英国政府环境管理计划的一部分,灌木篱墙管理要顺应英国景观发展轨迹和发展方式。本文通过简单介绍田园风景中的灌木篱墙管理,分析其相关的管理方式和措施,以促进英国灌木篱墙管理的迅速发展。

摘要 Abstract

树篱是英国景观的一个重要组成部分,为一些群体提供食物和住所。作为英国政府的环境管理计划的一部分,农民得到补贴,与此同时,“增强灌木篱墙管理”。尽管回声探索影响下的灌木篱墙管理对一些群体会产生巨大的有利影响,这些群体包括无脊椎动物和鸟类,这种回声探测管理将对小型哺乳动物群落产生什么样的影响目前还一无所知。


本研究的目的是调查增强灌木篱墙管理是否会影响田园景观灌木篱墙的特征和小哺乳动物的数量,是否会增加回声探测系统下树篱的数量。正在调查的“缓冲保护带”(2 m +未被利用的长满草的边界地带)有可能改善回声探测系统下的灌木篱墙管理。使用动态捕获方法,我调查了回声探测系统下树篱与非回声探测系统树篱之间的小哺乳动物数量多少。


Hedgerows are an important part of the British landscape, providing both food and shelter for a number of taxa. As part of the UK government’s Environmental Stewardship (ES) Scheme, farmers are granted subsidies for, amongst other things, ‘enhanced hedgerow management’. Although hedgerow management under ES is expected to have beneficial effects for taxa such as invertebrates and birds, less is known about the effects ES management will have on small mammal communities.


The aim of this study was to investigate whether this ‘enhanced hedgerow management’ is affecting hedgerow characteristics in pastoral landscapes and whether small mammal abundances are increased under ES managed hedgerows. ‘Conservation buffer strips’ (2m+ unimproved grassy margins) were investigated as a possible improvement to ES hedgerow management. Using live trapping methods, I investigated small mammal abundances in ES managed hedgerows compared with non-ES managed hedgerows.


Wood mice Apodemus sylvaticus and bank voles Clethrionomys glareolus were the most abundant species, with some captures of field voles Microtus agrestis and common shrews Sorex araneus. Small mammal abundances were increased in ES managed hedgerows, however, the presence of a ‘conservation buffer strip’ was more significant in increasing small mammal densities. ES management showed no definite effect on the hedgerows’ characteristics.


Introduction

Agricultural intensification since the 1940s has led to widespread and significant reductions in the biodiversity of many agricultural areas. This drive for greater yields has been linked with the population decreases seen in many species of farmland specialists and non-specialists who often inhabit farmland (Robinson and Sutherland, 2002). Farmland habitats can be categorised into non-linear habitats such as set-aside, cropped fields and woodland areas, and linear habitats, generally field boundaries, such as ditches, banks, streams and hedgerows. These field boundaries remain relatively undisturbed areas and are therefore significant wildlife corridors within otherwise inhospitable agricultural landscapes (Tew, 1994).


Although there continued to be a reduction in total area of hedgerows within the UK during the 80s and early 90s, the last decade has seen small increases in the area of hedgerow as their conservation significance became more documented (Barr and Gillespie, 2000). This increase in the number of hedgerows has been driven by government backed grants. Countryside Steward (CS), set up in 1991 encouraged selected farmers to enhance and conserve the wildlife within their farms, a large part of this involved the laying of new hedgerows. The CS schemes have now been superseded by the Environmental Stewardship Schemes. More recently, hedgerow grant pilot schemes have been set up in a number of reg论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
