RAMAS Red List gives a different threat classification than I expected. Why is the difference?
A. In almost all cases, the difference between the IUCN classification that RAMAS Red List gives and one that you obtain by running through the IUCN criteria stems from the parameters you did not specify. If you leave a parameter blank (empty), RAMAS Red List assumes that it is “unknown” and assigns the widest possible range to this parameter. (Why? See below.) For example, if you leave the Future reduction parameter blank, the program assumes the interval [0, 100]%. To correct, make sure that all parameters are specified. If you have no data on a parameter, but you believe that it should not make a difference in the threat status of the species, you may choose to ignore this parameter. To do this, click on the button next to the parameter field. This button looks like , and clicking it will open the Value editor window. In this window, check the box for “Ignore this value”. We do not recommend ignoring any parameters. Please see the User Manual for a discussion of unknown values. Othe
