Using self-sustaining wild rice mesocosms, we collected data on the population response to sulfate, as well as iron and litter, which both may modify the production and availability of sulfide to plants. Wild rice also experiences natural population oscillations due to delays in release of nitrogen from decomposing litter. We use this data to investigate how sulfate-induced population declines interact with stable litter-driven population cycles. Population data was collected 2014-2019, and geochemical data (iron, sulfide, pH) was collected in 2019, after 5 years of of a factorial design treatment (sulfate, iron, litter).CC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/Wild riceSulfideMesocosmsLitterIronPopulation oscillationsDatasethttps://doi.org/10.13020/cq0g-r486
