Density (g/mL)	1.31 ± 0.09	1.21 ± 0.08	1.26 ± 0.09	0.72 ± 0.04
Organic (%)	1.63 ± 0.40	1.68 ± 0.20	1.66 ± 0.25	1.94 ± 0.33
Total N mg/g	0.0036 ± 0.0005	0.0039 ± 0.0010	0.0037 ± 0.0006	0.0053 ± 0.0004

Figure 2. Example of plant growth assessment with area of presence and homogenous area of growth indicated. This site was planted with wild celery (Vallisneria americana).

Figure 4. Mean homogenous area of growth at open (hollow) and protected (stippled) sites by year of transplant in shallow plots. Initial planted area (indicated by dashed line) was 0.25 m². Note area axis is in logarithmic scale of base 10. Error bars are ±1 SE.
