Coastal wetlands provide critical habitat for aquatic organisms and important ecosystem services for the terrestrial and aquatic landscapes they bridge, but increasingly common invasive macrophytes disrupt plant communities, food webs, habitat structure and littoral-pelagic linkages. In Laurentian Great Lakes coastal wetlands, invasive cattails (Typha √óglauca and T. angustifolia, hereafter Typha) homogenize ecosystem structure and reduce nearshore dissolved oxygen, and plant, fish, and macroinvertebrate diversity. We hypothesize that management treatments that reduce Typha and its abundant litter promote structural heterogeneity and mitigate physiochemical and biodiversity impacts. To test this hypothesis, we implemented a large-scale (2048 m2 treatment units), multi-site (four coastal wetlands) experiment in northern Michigan (USA) to examine how invasive Typha mechanical harvesting treatments (biomass harvest, aquatic connectivity channels, Typha-dominated control) altered fish, macroinvertebrate, plant, larval amphibian abundance and diversity, and water quality for two-years post-treatment. We collected fish, macroinvertebrates, plant, larval amphibian, and water quality data from for two years following the implementation of management treatments. These data are presented in this archived dataset.
