Biomonitoring of water quality and catchment management are often disconnected, due to mismatching scales. Considerable effort and money are spent each year on routine reach-scale surveying across many sites, particularly in countries like the UK, where nationwide sampling has been conducted using standardised techniques for many decades. Most of these traditional freshwater biomonitoring schemes focus on pre-defined indicators of organic pollution to compare observed vs expected subsets of common macroinvertebrate indicator species. Other taxa, including many threatened species, are often ignored due to their rarity, as are many invasive species, which are seen as undesirable despite becoming increasingly common and widespread in freshwaters, especially in urban ecosystems. Both these types of taxa are often monitored separately for reasons related to biodiversity concerns rather than for gauging water quality. Repurposing such data could therefore provide important new biomonitoring tools that can help catchment managers to directly link the water quality they aim to control with the biodiversity they are trying to protect. Here we used extensive data held in the England Non-Native and Rare/Protected species records that track these two groups of species as a proof-of-concept for linking catchment scale management of freshwater ecosystems and biodiversity to a range of potential drivers across England. We used national land use (Centre for Ecology and Hydrology land cover map) and water quality indicator (Environment Agency water quality data archive) datasets to predict, at the catchment scale, the presence or absence of 48 focal threatened or invasive species of concern routinely sampled by the English Environment Agency, with a median accuracy of 0.81 area under the receiver operating characteristic curve. A variety of water quality indicators and land-use types were useful in predictions, highlighting that future biomonitoring schemes could use such complementary measures to capture a wider spectrum of drivers and responses. In particular, the percentage of a catchment covered by freshwater was the single most important metric, reinforcing the need for space/habitat to support biodiversity, but we were also able to resolve a range of key environmental drivers for particular focal species. We show how our method could inform new catchment management approaches, by highlighting how key relationships can be identified and how to understand, visualise and prioritise catchments that are most suitable for restoration or water quality interventions. The scale of this work, in terms of number of species, drivers and locations, represents a significant step towards forging a new approach to catchment management that enables managers to link drivers they can control (water quality and land use) to the biota they are trying to protect (biodiversity).

在国家范围内预测流域对生物多样性的适宜性

由于尺度不匹配,水质的生物监测和集水区管理经常脱节。每年都花费大量精力和金钱在许多地点进行常规范围调查,特别是在像英国这样的国家,几十年来一直使用标准化技术进行全国抽样。这些传统淡水生物监测方案中的大多数都侧重于预先定义的有机污染指标,以比较观察到的与预期的常见大型无脊椎动物指标物种的子集。其他分类群,包括许多受威胁物种,由于它们的稀有性而经常被忽视,许多入侵物种也是如此,尽管它们在淡水中变得越来越普遍和普遍,但在城市生态系统中变得越来越普遍和普遍,但被认为是不可取的。出于与生物多样性相关的原因,而不是为了衡量水质,这两种类型的分类群通常被单独监测。因此,重新利用这些数据可以提供重要的新生物监测工具,可以帮助流域管理者将他们想要控制的水质与他们试图保护的生物多样性直接联系起来。在这里,我们使用了英格兰非本地和稀有/受保护物种记录中保存的大量数据,这些记录跟踪这两组物种,作为将淡水生态系统和生物多样性的流域规模管理与英格兰的一系列潜在驱动因素联系起来的概念验证. 我们使用国家土地利用(生态和水文中心土地覆盖图)和水质指标(环境署水质数据档案)数据集在流域范围内预测,英国环境署定期采样的 48 种重点受威胁或入侵物种的存在与否,接受者操作特征曲线下的中位准确度为 0.81 面积。各种水质指标和土地利用类型在预测中很有用,强调未来的生物监测计划可以使用这些补充措施来捕捉更广泛的驱动因素和响应。特别是,淡水覆盖的流域百分比是唯一最重要的指标,加强了对空间/栖息地支持生物多样性的需求,但我们也能够解决特定重点物种的一系列关键环境驱动因素。我们展示了我们的方法如何为新的流域管理方法提供信息,通过强调如何识别关键关系以及如何理解、可视化和优先考虑最适合恢复或水质干预的集水区。这项工作的规模,在物种、驱动因素和地点的数量方面,代表着朝着形成流域管理新方法迈出的重要一步,使管理人员能够将他们可以控制的驱动因素(水质和土地利用)与他们所在的生物群联系起来试图保护(生物多样性)。
