    文化教育:雪梨奥林匹克公园管理局(2004)报告说:成熟时黄色的花朵,很容易用来识别秘鲁水丁香(Ludwigia peruviana)。早期发现是重要的,广大市民也可以发挥防止这种入侵植物的蔓延的重要作用。但是,所有丁香属植物都有黄色的花朵,秘鲁水丁香的毛叶,嫩枝,以及大型黄色的花朵是其特征(南雅各布布pers.comm, 2006)。 English  français   

    A variety of different management tools have been used at the various sites, depending on the reasons for management and the characteristics of the site. Habitat manipulation was used with great success on the Airport colony. The ibis were nesting on an introduced weed species, L. peruviana, in the Botany Wetlands. This was considered a great risk for birdstrike due to the close proximity to the main east-west runway. The complete removal of the weed prevented the colony from using the site in subsequent seasons (G. Ross, pers. comm.) (Bankstown, 2004).
    Botany Wetlands
    Efforts to restore the Wetland's ecological and environmental values and rehabilitate the stormwater basin commenced in 1996. This required the initial removal of entrenched weed infestations, and replacement of the weed dominated vegetation by native, aquatic and terrestrial vegetation. The strategy for removal of the massive weed infestations was repeated, timely applications of herbicides, followed by large-scale mechanical and manual weed removal and controlled burning of dead plants. The strategy for revegetation and restoration of the areas cleared was based on natural regeneration by the native macrophytes, supplemented by active replanting of a range of desired species in order to maximise species diversity. Species were selected for plantings based on their ability to rapidly colonise sites, resist weed invasion, withstand herbicide spray effects, and provide desirable habitat and aesthetic characteristics. Water level management was essential for successful weed control operations by improving access and encouraging subsequent revegetation. This paper provides an overview of the problems encountered in implementing the strategies, some solutions, and discusses the success of the operations (Chandrasena and Sim, 1999).
    The Longview Diking District uses mechanical methods to remove water primrose and other noxious plants from the canals and ditches in Longview/Kelso. Other methods such as cutting, covering with opaque materials, and using the aquatic herbicide (Rodeo®) may be effective. It is not likely that grass carp would find water primrose to be palatable (Washington State Department of Ecology, 2001)
    New South Wales
    Class 1 pests established in Queensland are subject to eradication from the state. Landowners must take reasonable steps to keep land free of Class 1 pests. It is a serious offence to introduce, keep or supply a Class 1 pest without a permit issued by the Department of Natural Resources and Mines. Penalties of up to $60 000 apply. (Department of Natural Resources and Mines, 2005).
    New Zealand
    L. peruviana is included in the First Schedule of the National Pest Plant Accord. All plants on the list are designated as Unwanted Organisms, and are banned from sale, propagation and distribution throughout New Zealand. Please see National Pest Plant Accord for the complete list.
    L. peruviana is being sold as an ornamental species because of its showy yellow flowers. Lake residents are strongly discouraged from planting water primrose in lakes, private ponds, in a flood zone, or in natural waterbodies. As of January 2001, these plants will no longer be offered for sale in Washington (Washington State Department of Ecology, 2001).

            摘要: This report is the second stage in the development of a Border Control Programme for aquatic plants that have the potential to become ecological weeds in New Zealand. Importers and traders in aquatic plants were surveyed to identify the plant species known or likely to be present in New Zealand. The Aquatic Plant Weed Risk Assessment Model was used to help assess the level of risk posed by these species. The report presents evidence of the various entry pathways and considers the impact that new invasive aquatic weed species may have on vulnerable native aquatic species and communities.
