ABSTRACT Farming intensification negatively effects native habitat and associated biodiversity in New Zealand. Planting native species around field margins has been proposed as a means of restoring biodiversity within this highly modified landscape. To test this hypothesis, we collected invertebrates on a dairy farm at Lincoln, Canterbury, in three habitat types: native plantings in field corners, native plantings along a double fence line, and pasture. Invertebrates were collected from pitfall traps, yellow pan traps, wooden discs and leaf litter samples were collected from the sites over summer. Assemblages of spiders, flying insects, slugs and litter mites in the planted areas had distinct compositions compared with those found in adjacent pasture. Species richness of native spiders was increased in the planted areas compared with adjacent pasture, as was the abundance of ecosystem service providers, such as honeybees, parasitoid wasps and hoverflies. Exotic slugs were significantly more abundant under discs in pasture than in planted areas. However, not all native or beneficial invertebrates responded positively to the planted areas. Further research is required to examine whether these results are repeatable at other locations, if invertebrate assemblages at this location develop further over time, and to evaluate whether any perceived benefits of these service providers can be quantified in terms of meaningful endpoints such as reduced pest levels and/or increases in yield.

本地种植可以鼓励坎特伯雷奶牛场的本地和有益无脊椎动物吗？

摘要 农业集约化对新西兰的原生栖息地和相关生物多样性产生负面影响。在田地边缘种植本地物种已被提议作为在这个高度改造的景观中恢复生物多样性的一种手段。为了验证这一假设，我们在坎特伯雷林肯市的一个奶牛场收集了三种栖息地类型的无脊椎动物：田角的本地植物、双栅栏线上的本地植物和牧场。整个夏季，从陷阱陷阱、黄盘陷阱、木盘和落叶样品中收集了无脊椎动物。与在邻近牧场发现的那些相比，种植区的蜘蛛、飞虫、蛞蝓和凋落物螨的组合具有不同的成分。与邻近牧场相比，种植区的本地蜘蛛物种丰富度有所增加，生态系统服务提供者（如蜜蜂、寄生蜂和食蚜蝇）的丰富度也是如此。外来蛞蝓在牧场的圆盘下比在种植区的数量要多得多。然而，并非所有本地或有益的无脊椎动物都对种植区域做出积极反应。需要进一步研究以检查这些结果在其他地点是否可重复，如果该地点的无脊椎动物组合随着时间的推移进一步发展，并评估这些服务提供者的任何感知利益是否可以根据有意义的端点（例如害虫水平降低）量化和/或产量增加。外来蛞蝓在牧场的圆盘下比在种植区的数量要多得多。然而，并非所有本地或有益的无脊椎动物都对种植区域做出积极反应。需要进一步研究以检查这些结果是否在其他地点可重复，如果该地点的无脊椎动物组合随着时间的推移进一步发展，并评估这些服务提供者的任何感知利益是否可以通过有意义的端点（例如害虫水平降低）量化和/或产量增加。外来蛞蝓在牧场的圆盘下比在种植区的数量要多得多。然而，并非所有本地或有益的无脊椎动物都对种植区域做出积极反应。需要进一步研究以检查这些结果是否在其他地点可重复，如果该地点的无脊椎动物组合随着时间的推移进一步发展，并评估这些服务提供者的任何感知利益是否可以通过有意义的端点（例如害虫水平降低）量化和/或产量增加。
