Figure 2. Species accumulation curves for documenting completeness of sampling. (A) Butterflies in rural habitats, (B) butterflies in urban habitats, (C) birds in rural habitats, (D) birds in urban habitats, (E) vegetation in rural habitats, and (F) vegetation in urban habitats. The thick black line is the species accumulation curve estimated using the Mao Tao method with 95% confidence intervals shaded in grey. The number of species identified is shown, along with the number of species predicted for twice the number samples collected, and percentage completion of sampling.
