    FIG. A1. Plot design. Vertical center line indicates treatment boundary. Crosshatching indicates herbicide treatment area, including variable buffer zone on three sides of treatment (most buffers were several hundred meters, one was 50 m). Treatment sides of plots were randomly assigned. Seed-removal cages begin 10 m from the treatment boundary and are separated by 30 m thereafter. Seedling emergence and recruitment cages start approximately 20 m from the treatment boundary and are separated by 40 m. Seed-removal cages are located on the primary transects that are spaced 50 m apart and seedling emergence and recruitment transects are on secondary transects that are 10 m from the primary transects. Trap stations indicate where mice were sampled (10-m spacing). Symbols for cages are oversized relative to plot scaling.
