Management of the invasive Phragmites australis haplotype has focused on controlling its abundance in wetlands where it reduces biodiversity. However, little information is available on establishment of native communities and reinvasion by seed following removal using herbicides. The potential for reinvasion and development of native vegetation were evaluated using a seedbank assay and a vegetation survey along gradients from the channel edge to the marsh interior (0, 5 and 20 m distance) in three tidal freshwater marsh sites - Natural, treatment 6 months prior (Treated), and untreated (Phragmites). Recolonization potential from the seedbank was high with >18,500 seedlings m⁻² in Treated samples. Richness and density of native species were low in the interior of Treated and Phragmites sites as compared to the Natural marsh. Few species were present in Treated site vegetation 11 months following treatment where P. australis litter comprised a large proportion of the cover. Results indicate that planting native vegetation to outcompete P. australis seedlings and total removal of P. australis to cut off the seed supply may be necessary for successful longer-term restoration and establishment of native species.

入侵性芦苇单倍型的管理集中在控制其减少生物多样性的湿地中的丰度上。但是，很少有关于建立本地社区和使用除草剂清除种子后再入侵的信息。在三个潮汐淡水沼泽地中，使用种子库测定法和沿河道边缘至沼泽内部（0、5和20 m距离）的坡度进行植被调查，评估了天然植被的再入侵和发展的潜力-自然，处理6个月之前（已处理）和未处理（芦苇）。来自种子库的再定殖潜力很高，> 18,500苗m ^-2在处理过的样品中。与天然沼泽相比，已处理和芦苇站点内部的物种丰富度和密度较低。处理后11个月，处理过的植被中几乎没有物种，其中P. australis凋落物占覆盖的大部分。结果表明，要成功地长期恢复和建立本地物种，必须种植天然植被以胜过澳大利亚P. australis幼苗，并彻底清除澳大利亚P. australis以切断种子供应。
