Table 1. Risk evaluation by species for southern African anatids. Estimates have been rounded to the nearest 0.1. The risk score is calculated by summing the other columns, dividing by the maximum possible total of 35, and converting to a percentage. Note that all of the species commonly called "goose" in southern Africa are actually ducks. Further details of assessment categories and species names are provided in the Appendix.
