一般影响
ERDC报告说：粉绿狐尾藻(Myriophyllum aquaticum)生长在滞水区，溪流边缘，湖泊，池塘，排水和灌溉沟渠，运河，回水区，泥坑和舄湖。可能会形成相当密集的植群，有时漂流的浮动植垫会阻塞息航道妨碍航行。华盛顿州生态部(2003)报告说：粉绿狐尾藻(Myriophyllum aquaticum)，已被引入全球各地，用于室内和室外水族馆。它也是一个受欢迎的水生园林植物。然而，它已经从种植区逃脱，并藉由植物碎片蔓延。虽然粉绿狐尾藻(Myriophyllum aquaticum)可以提供一些水生生物遮蔽掩护，它会严重改变湖泊和溪流的物理和化学性质。粉绿狐尾藻会对水生食物网的基础藻类产生遮荫，进而改变水生生态系统。此外，此植物提供蚊子幼虫的栖地选择。此植物还会限制这些水体的休闲用途。
地点特有的影响：Southern Africa (Africa) 
物理干扰: Apart from invading rivers, lakes and dams, Myriophyllum aquaticum parrot's feather is also known to invade the shallow parts of most water bodies in southern Africa. It can hinder stream flow, clog water inlets, interfere with fishing and fish culture, navigation and cause drowning of humans and animals. It also provides a breeding place for disease-carrying mosquitoes and snails (Henderson & Cilliers, 2002). Guernsey
降低本地生物多样性: Myriophyllum aquaticum is a major problem in ponds and wetlands, where it has eliminated many native species (David, 2003 in Varnham, 2006). United States (USA)
与其它入侵物种相互作用: In addition, the plant provides choice mosquito larvae habitat (Washington State's Department of Ecology 2003).
改变营养机制: Infestations can alter aquatic ecosystems by shading out the algae in the water column that serve as the basis of the aquatic food web (Washington State's Department of Ecology 2003).
栖地改变: While Myriophyllum aquaticum may provide cover for some aquatic organisms, it can seriously change the physical and chemical characteristics of lakes and streams (Washington State's Department of Ecology 2003).
滋扰人类: The plant can also restrict recreational opportunities in these bodies of water (Washington State's Department of Ecology 2003).
物理干扰: ERDC (UNDATED) states that, "Myriophyllum aquaticum populations may be quite dense, sometimes as floating mats that have been uprooted, often choking waterways and impeding navigation." California (United States (USA))
物理干扰: In California, the Myriophyllum aquaticum is becoming an increasing problem in irrigation and drainage canals. A 1985 survey of irrigation, mosquito abatement, flood control, and reclamation agencies in California indicated that parrotfeather infested nearly 600 miles of waterways and over 500 surface acres (Washington State's Department of Ecology 2003).
