在欧洲，由于集约农业和荒废，管理广泛的草原经历了大规模的下降。它们的恢复支持了耕作系统中节肢动物的生物多样性。我们研究了草地恢复过程中节肢动物建立的限制因素，包括52个自然更新或直播建立的恢复地点的时间序列。我们的研究涵盖了10目363种节肢动物，包括食草动物、食草动物、捕食性动物和传粉者。采用陷阱诱捕法、吸力采样法和样带采样法对这些样品进行采样。恢复地植物群落与目标物种丰富草原的相似性与节肢动物群落与同一草地的相似性呈正相关。有证据表明，位于物种丰富的草原遭受历史性大规模丧失的景观(1930-2015年)的恢复地点在复制节肢动物群落组成方面的成功率较低，并支持最低水平的物种丰富度。修复地点的年龄是某些营养水平修复成功的预测因子。例如，在最古老的恢复地点，捕食者的物种丰富度最高。然而，只有当遗址规模较大或位于物种丰富的草原历史上损失最少的景观时才会出现这种情况。站点内管理的影响也影响到节肢动物群落。年度采伐频率对有害食肉动物物种丰富度产生负面影响，并针对包括食草动物单食性在内的特征进行选择。节肢动物物种丰富度总体上与草皮高度呈正相关。这些结果强调了在草原恢复过程中成功复制花卉群落以及景观和管理因素的相对重要性。这对未来的农业环境计划有影响。特别是，实现高质量的现场管理，最大限度地建立工厂社区，需要成为任何恢复计划的初始重点。
In Europe, extensively managed grasslands have undergone large-scale declines due to intensive agriculture and abandonment. Their restoration supports arthropod biodiversity within farming systems. We investigated limiting factors for arthropod establishment during grassland restoration across a chronosequence of 52 restoration sites established by either natural regenerating or direct seeding. Our study covered 363 arthropod species of 10 orders, including detritivores, herbivores, predators and pollinators. These were sampled using pitfall traps, suction sampling and transect walks. The similarity of plant communities on restoration sites to target species rich grasslands was positively correlated with the similarity of the arthropod communities to these same grasslands. There was evidence that restoration sites located in landscapes suffering from historic large-scale loss of species rich grassland (1930–2015) had lower success in replicating the composition of arthropod communities and supported the lowest levels of species richness. The age of the restoration site was a predictor of restoration success for some trophic levels. For example, predator species richness was greatest in the oldest restoration sites. However, this was only the case were sites were either of large size or located in landscapes with the lowest historic loss of species rich grassland. Impacts of within site management also affected arthropod communities. The annual frequency of cutting negatively affected detritivores species richness, and selected against traits including herbivore monophagy. Overall arthropod species richness was positively correlated with sward height. These results emphasise the relative importance of the success with which the floral community is replicated, as well as landscape and management factors, during grassland restoration. This has implications for future agri-environmental schemes. In particular, achieving high quality within-site management that maximises establishment of the plant communities needs to be the initial focus of any restoration program.
