FIGURE SET

Figure 1a and 1b

Figure 1. The probability that small Lespedeza cuneata plants would (a) grow to a medium sized plant or (b) die from one year to the next. Figures modified from Schutzenhofer and Knight (2007). Chi-square analyses presented in Schutzenhofer and Knight (2007) show that there is a statistically significant difference in the fate of small plants (stay the same size, grow or die) between clipping treatments (Χ2=16.0, df=8, P=0.042).
