Our goal was to characterize the interactive feedback between garlic mustard (Alliaria petiolata) and European earthworm species in southwest Ohio. Earthworm community composition, abundance and biomass were compared between 0.1 m2 plots of garlic mustard, cut-leaved toothwort (Cardamine concatenate), wild ginger (Asarum canadense), or no plant cover. Exotic earthworms were present in the study site. Earthworm abundance and biomass did not correlate with garlic mustard percent cover. There was a greater density of earthworms in the fall than in the spring. Worm abundance differed between garlic mustard and wild ginger plots and cut-leaved toothwort and control plots, suggesting that earthworms may prefer to be located under plants that produce high biomass. Worm biomass did not differ between the plants. There was a greater abundance of endogeic worms below all plants, while anecic worms contributed the most biomass. Our results do not support strong feedback between garlic mustard and European earthworms.
