The popularity of constructed wetlands (CWs) in new residential development areas to remove nutrients and sediments from stormwater runoffs is increasing. However, with increased urbanisation and enhanced climate change, the need to continuously monitor the treatment effectiveness of these constructed wetlands (CWs) is important. Monitoring of these wetlands to assess their design capacities to reduce pollutants had been sporadically undertaken, and the information regarding the status of CWs is often not publicly accessible, hence, the fate of the CWs is a concern. To determine the barriers in monitoring effectively the treatment capacity of CWs, this paper presents the findings of a survey specifically targeting all the 32 local governments and water authorities who own and manage the CWs in metropolitan Melbourne. The survey highlighted that monitoring is affected by several factors including lack of funding, lack of expert knowledge, lack of guidance and maintenance, as well as technical feasibility. The opportunities and benefits in utilising citizen science programs and strengthening political influence were also noted. The results provide holistic insights into the barriers and opportunities in implementing routine monitoring of CWs.

了解监测城市地区人工湿地处理效果的问题——澳大利亚大墨尔本地区的案例研究

人工湿地 (CW) 在新的住宅开发区中越来越受欢迎，以从雨水径流中去除养分和沉积物。然而，随着城市化进程的加快和气候变化的加剧，持续监测这些人工湿地 (CW) 的处理效果非常重要。对这些湿地进行监测以评估其减少污染物的设计能力的工作是偶尔进行的，而且有关 CW 状态的信息通常无法公开获取，因此，CW 的命运令人担忧。为了确定有效监测 CW 处理能力的障碍，本文介绍了一项调查的结果，该调查专门针对墨尔本市区拥有和管理 CW 的所有 32 个地方政府和水务部门。调查强调，监测受到多种因素的影响，包括缺乏资金、缺乏专家知识、缺乏指导和维护以及技术可行性。还指出了利用公民科学计划和加强政治影响的机会和好处。结果提供了对实施 CW 常规监测的障碍和机会的整体见解。
