Abstract

Constructed water quality wetlands, designed to accept tile drainage and surface runoff, are a promising solution for reducing surface water nutrient loading from agricultural systems. In addition to their water quality benefits, these systems may also offset losses of migratory waterbird stopover sites resulting from historical and future agricultural drainage modernization. To assess this possibility, we developed spatially explicit habitat models informed with expert opinion to explore the: 1) potential of water quality wetlands to provide suitable stopover resources for waterbirds during spring migration; and 2) the extent these wetlands can offset likely losses of stopover resources due to drainage modernization. We focused our modeling on the Iowa portion of the Prairie Pothole Region of North America as it was a historically important area within this vital region for waterbirds, but it has experienced widespread subsurface drainage. Model results indicate that unmitigated drainage modernization is likely to have a large negative effect on spring migratory resources for dabbling ducks and shorebirds and minimal effect on diving ducks. Water quality wetland installations are likely to provide habitat for dabbling and diving ducks, but wetland installation is unlikely to completely offset habitat losses for dabbling ducks and shorebirds. Drainage modernization aside, our results indicate that water quality wetlands can address several environmental issues associated with agricultural expansion and intensification by improving water quality and providing wetland resources for waterbirds and other organisms. Field-scale research is needed to validate these results.

美国艾奥瓦州草原坑区不同农业管理情景下春季迁徙水鸟湿地资源模拟
人工湿地是一种很有前途的解决方案,用于减少农业系统对地表水的养分负荷。除了对水质有利外,这些系统还可以抵消由于历史和未来农业排水现代化而造成的迁徙水鸟中途停留点的损失。为了评估这种可能性,我们在专家意见的基础上建立了空间明确的栖息地模型,以探讨:1)水质湿地在春季迁徙期间为水鸟提供适当中途停留资源的潜力;2)这些湿地在多大程度上可以抵消由于排水现代化而可能造成的中途停留资源损失。我们将建模的重点放在北美草原坑穴地区的爱荷华州部分,因为它在这个至关重要的地区对水鸟来说是一个历史上重要的地区,但它经历了广泛的地下排水。模型结果表明,未缓解的排水现代化可能对涉水鸭和滨鸟的春季迁徙资源产生较大的负面影响,对潜水鸭的影响最小。水质湿地设施可能为涉水鸭和潜水鸭提供栖息地,但湿地设施不太可能完全抵消涉水鸭和滨鸟栖息地的损失。除了排水现代化,我们的研究结果表明,水质湿地可以通过改善水质和为水鸟和其他生物提供湿地资源来解决与农业扩张和集约化相关的几个环境问题。需要实地规模的研究来验证这些结果。

期刊介绍: Wetlands is an international journal concerned with all aspects of wetlands biology, ecology, hydrology, water chemistry, soil and sediment characteristics, management, and laws and regulations. The journal is published 6 times per year, with the goal of centralizing the publication of pioneering wetlands work that has otherwise been spread among a myriad of journals. Since wetlands research usually requires an interdisciplinary approach, the journal in not limited to specific disciplines but seeks manuscripts reporting research results from all relevant disciplines. Manuscripts focusing on management topics and regulatory considerations relevant to wetlands are also suitable. Submissions may be in the form of articles or short notes. Timely review articles will also be considered, but the subject and content should be discussed with the Editor-in-Chief (NDSU.wetlands.editor@ndsu.edu) prior to submission. All papers published in Wetlands are reviewed by two qualified peers, an Associate Editor, and the Editor-in-Chief prior to acceptance and publication. All papers must present new information, must be factual and original, and must not have been published elsewhere.
