了解食草动物的分布情况对植物群落的保护管理具有重要意义。大规模控制野生和家养大型食草动物种群通常用于操纵其影响。然而，大规模的人口密度和当地的影响之间的关系往往是薄弱的植物群落的空间布局，和草食动物的偏好，可以驱动草食动物的栖息地利用。我们测试了接近的一个首选的植物群落的规模高达3 km 2的放牧影响的红鹿（马鹿）对4个植物群落的保护重要性的影响。我们还测试了放牧的影响和草食动物密度之间的关系，在规模的鹿管理单位的网站上。放牧的影响是衡量放牧的直接和间接指标。首选物种丰富的草地在目标站点附近的面积影响放牧的影响首选（草地）和不太首选（健康）社区。放牧对石楠的影响更高时，有更多的物种丰富的草地在1000米。当500 m范围内物种丰富草地面积较小时，放牧对物种丰富草地的影响较小，特别是当500-1000 m范围内物种丰富草地面积较大时，放牧对物种丰富草地的影响更小。草食动物密度只有微弱的放牧影响。当植物群落对放牧的敏感性或需要放牧来维持它们的同时存在时，在管理两者的保护方面存在着内在的冲突。我们的理解相邻社区的空间布局作为草食动物的影响的决定因素的作用，可以告知一个植物群落的保护比其他的管理和优先顺序。
Understanding the distribution of herbivory is of great importance to planning the conservation management of plant communities. Control of wild and domestic large herbivore populations at large scales is commonly used to manipulate their impacts. However, the relationship between large scale population density and local impacts is often weak as the spatial layout of plant communities, and the herbivores' preferences for them, can drive the herbivores' habitat use. We tested the effects of proximity of a preferred plant community at scales up to 3 km2on the grazing impact of red deer (Cervus elaphus) on four plant communities of conservation importance. We also tested the relationship between grazing impacts and herbivore density at the scale of deer management units on the site. Grazing impact was measured using direct and indirect indicators of grazing. The area of the preferred species-rich grassland in proximity to the target site influenced grazing impacts on both preferred (grassland) and less-preferred (heath) communities. Grazing impacts on heaths were higher when there was more species-rich grassland present within 1000 m. Grazing impacts on species-rich grasslands were lower when the area of species-rich grassland within 500 m was small, especially when there was also more species-rich grasslands in the wider area (500–1000 m away). Herbivore density was only weakly correlated to grazing impacts. Where plant communities with contrasting grazing sensitivity to or requirement for grazing to maintain them exist side by side, there is an inherent conflict in managing for the conservation of both. Our understanding of the role of spatial layout of adjacent communities as a determinant of herbivore impact may inform the management and prioritisation of the conservation of one plant community over others.
