Note: Even probability P = total proportion of species endangered/total number of species endangered = 8.02/41 = 0.1955. Binomial probability of each endangered species was calculated using statistical software Minitab. ^∗∗∗ indicates significant difference at  ≤ 0.001 level of significance, ^∗∗ indicates significant difference at  ≤ 0.01 level of significance, and ^∗ indicate significant difference at p ≤ 0.05 level of significance.
