Table 1. Results (mean + 1 SE) of seed bank sampling in the prescribed burn area (1995, n = 5; 1998, n = 7) for the total number of intact seeds/m2, the number of viable seeds/m2, and the percentage of viability in samples from the top 5 cm of soil and next 5 cm of soil below that. Asterisks indicate a significant difference between top and bottom samples (paired t tests, P< 0.05).
