While artificial farmland drainage has allowed the development of a highly productive agriculture, the availability of periodically flooded arable land as a niche habitat for a broad range of animal and vascular plant species has diminished. Accordingly, many species depending on temporary wetlands are endangered, already extinct or extirpated in Switzerland and other European countries. Some arable fields with temporary pools can still be observed in Switzerland. However, it is not known how suitable such small temporary ponds are as habitats in the modern, intensively-managed agricultural landscape, where disturbance rates are high, and connecting wetland habitats are scarce. We surveyed 120 fields across 10 hot spot regions for potential waterlogging in Switzerland, investigating the effect of temporary waterlogging on the diversity of arable plant and ground beetle species. Half of the fields were heavily influenced by waterlogging, while the other half represented conventional crop field controls. We found that wet fields exhibited a higher number of vascular plant and carabid species on average compared to control fields. This difference was explained by the presence of more hygrophilic plant and ground beetle species on wet fields. While we did find more hygrophilic species on wet fields, the threatened character species of temporary wetland habitats were mostly absent despite availability in regional species pools. These results suggest that temporary pools still provide the raw environmental characteristics that hygrophilic species require in the agricultural landscape. However, alternative management schemes are required to transform them into habitats that can effectively support high-priority, threatened species of temporary wetlands.

尽管人工农田排水使高产农业得以发展，但定期淹没的可耕地作为各种动植物和维管植物物种的利基生境的可用性已经减少。因此，许多依赖临时湿地的物种在瑞士和其他欧洲国家已濒临灭绝或灭绝。在瑞士仍然可以观察到一些带有临时池的耕地。然而，尚不知道这样的小型临时池塘在现代的，集约化管理的农业景观中是否适合居住，那里的干扰率很高，而相连的湿地栖息地却很少。我们对10个热点地区的120个油田进行了调查，以了解瑞士的潜在涝灾，调查临时淹水对可耕植物和地面甲虫物种多样性的影响。一半的田地受到涝灾的严重影响，而另一半则代表了常规作物田间的控制。我们发现，与对照田相比，湿田平均表现出更高数量的维管植物和钩兰物种。造成这种差异的原因是在湿地上存在更多具有亲水性的植物和地面甲虫物种。尽管我们确实在湿地上发现了更多的嗜湿性物种，但是尽管存在区域物种库，但临时缺水湿地栖息地的受威胁特征物种却大多不存在。这些结果表明，临时池仍提供了农业景观中嗜湿性物种所需的原始环境特征。然而，
