Data for experimental conservation translocations of an aquatic invertebrate (Gammarus lacustris) in Minnesota USA from years 2017-2020

The dataset accompanies the scientific article, "Experimental conservation translocations of an aquatic invertebrate (Gammarus lacustris) within prairie and forest-transitional wetlands". In this study, we conducted a before-after/control-impact experiment to test the efficacy of conservation translocation for re-establishing abundant populations of the freshwater amphipod Gammarus lacustris in years 2017-2020. Each site (n=19) comprised at least 2 wetland basins, generally with one basin receiving translocated G. lacustris from a local donor and the other serving as a nearby control basin. The dataset contains information about the sites and the number of amphipods and density of amphipods detected at each basin.
