Importance and distribution in Luxembourg

H. ranunculoides is an aquatic plant that thrives in slow-flowing water bodies, particularly in ditches, canals, lakes and ponds. It prefers eutrophic waters, but it can also colonise marshes and mesotrophic water bodies. The species forms dense interwoven mats of vegetation which can quickly cover the entire water surface. Due to its vigorous growth, this plant causes loss of light and reduction in dissolved oxygen content in the water. As a consequence, the native submerged and water-edge plant species can be outcompeted and ecosystem functions can be altered (Source: http://ias.biodiversity.be/species/show/63).

The species has not yet been observed in Luxembourg.
