Representativeness is obtained after dividing the Security Index (1 –I_i) by the ratio of mainland Spain covered by the network (i.e. 0.00667). We repeated the random Securities 20 times, so values of the third column range from 0 to 20, being 20 for well-represented species and 0 for under-represented species according to this approach.
