采用多尺度方法研究沼泽鸟类群落对周围基质和局部尺度植被特征的农业用地利用的响应。对于高地特有物种的组合而言，750 m 空间尺度上集约化管理的草地范围呈负相关。这对丰富度的影响比荒原本身的当地植被特征更大。同样，对于受保护的物种来说，750 m 尺度景观林地覆盖的增加也增强了其丰富度。这种组合水平的关联可以掩盖单个物种的反应。例如，一些高地专家，如红松鸡和金鸻，与景观中的密集草地呈负相关，而其他受保护的物种，尤其是麻鹬、田凫和鹬都表现出正相关。这些结果表明，景观规模的高地农业对于维持英国荒原鸟类的丰富性和组成是不可或缺的，因此荒原的土地管理行动不应仅限于该栖息地。 (c) 2010 Elsevier B.V. 保留所有权利。
A multi-scale approach was used to investigate the response of the moorland bird community to agricultural land-use in the surrounding matrix and local-scale vegetation characteristics. For the assemblage of upland specialist species, there was a negative association with the extent of intensively managed grassland at the 750 m spatial scale. This had a greater influence on richness than the local vegetation characteristic of the moorland itself. Similarly, for species of conservation concern, richness was enhanced by increased landscape-level woodland cover at the 750 m scale. Such assemblage-level associations can mask the responses of individual species. For example, some upland specialists, such as the red grouse and golden plover, were negatively associated with intensive grassland in the landscape, while other species of conservation concern, notably curlew, lapwing and snipe all showed positive relationships. These results indicate that upland agriculture at the landscape-scale is integral to maintaining the richness and composition of UK moorland birds and hence land management actions for moorland should not be limited to that habitat alone.
