Fig. 4. Smoothed collector curve for the 70 surveyed plots (black solid line. Its 95% confidence interval is represented by dotted black lines) and the extrapolated samplingcurve (dashed gray. Its 95% confidence interval is represented as dotted gray lines) for a sampling effort three times greater (210 plots) than the actual sampling effort. Thelargest (Chao 2) and smallest (Jackknife 1) estimated richness for the study site is shown as horizontal dashed black lines.
