Phragmites australis or Common Reed is a robust native wetland plant and an important component of many of our wetland plant communities, but can become invasive and thwart wetland restoration efforts. Phragmites is difficult to control and its successful control is likely to require a combination of abiotic (e.g. water regime), biotic (e.g. shading) and physical interventions (e.g. slashing). I will present two case studies on efforts to control Phragmites, one in which we assessed the efficacy of slashing and flooding, the other in which various combinations of slashing, matting and planting were trialled. Despite setbacks, some level of Phragmites control and wetland restoration were achieved in both cases. Appropriate control measures and control success were dependent on wetland context and realistic restoration goals.
