Appendix B. Figures showing (1) an overview of the study area and study design; (2) Sago pondweed tuber biomass densities in the experimental grid; (3) mean Sago pondweed tuber density for plots in which aboveground biomass was removed during different stages of the growing season; and (4) the mean Sago pondweed biomass density encountered by a swan when it made short and long movements from patches with different initial tuber density classes.
