Tarp impacts on weed growth

These data demonstrate the impacts of tarps on weed growth. We surveyed weeds weekly for five weeks after tarp removal. Weeds were identified to species and we calculated species richness, Shannon’s diversity, and total cover (%) for each plot (plots were 1 m x 2 m). We additionally include the cover for specifically purslane, a weed species of interest. <br> For more information, please refer to Kinnebrew et al. 2022 (https://doi.org/10.1080/21683565.2022.2146254) or contact Dr. Kinnebrew at [e-mail]. <br> Column Names and Explanations: <br> 1. Farm: the farm site (“A,” “B” or “C”) where the plot was located. All farms were located in Chittenden County, Vermont, USA <br> 2. Sampling: the sampling period, indicating the number of weeks after tarps were removed <br> 3. Plot_Replicate: the treatment replicate number on each farm (1-6 for each treatment on each farm) <br> 4. Plot_ID: the unique identifier for each spatial plot <br> 5. SpRichness: species richness (number of weed species) <br> 6. Shannon: Shannon’s diversity of weed species <br> 7. Total_Cover: summed cover (%) within the plot area of all individual weed species’ cover (cover can exceed 100% when there are multiple layers of weed cover) <br> 8. Purslane_Cover: percent of only purslane cover within the plot area
