Data were collected on the abundance of plants in a 10-year weeding experiment of garlic mustard, located at Trillium Trails Park in Pennsylvania. Garlic mustard was weeded annually to suppress its abundance, and the impacts of garlic mustard were measured based on the response of the plant community to garlic mustard weeding. Because garlic mustard is known to suppress mycorrhizal fungi, the mycorrhizal status of each plant species was determined and recorded. The experiment was arranged in a blocked design, where plots had subareas with and without garlic mustard removal. Cover of each plant species was measured as the average percent cover recorded in 18 2x2 meter quadrats with garlic mustard removed per plot and 18 2x2 meter subplots with garlic mustard remaining per plot.
