\[RLI^t=1 - \frac{\sum_{i}^{n}S_i\cdot W_i}{N\cdot W_{EX}}\]Where: \(S_it\)is the number of species for category i, \( w_i\)is the weight of category i (1 for ¿almost threatened¿ up to 5 ¿Extinct¿), \N\) is the total number of species considered and \(W_{EX}\)is the weight for category ¿Extinct¿. For the calculation of this indicator the wild species present in Spain are considered according to the data of the Spanish Inventory of Natural Heritage and Biodiversity for which its category of global IUCN threat has been determined. In order for year-on-year comparisons to be made, the indicator requires comparison of the same set of species each year. For this reason, when determining the category of threat of new species, the indicator is reviewed retrospectively, assuming that the most recent assessment applies since the first set of species was evaluated. \(W_{EX}\)Dollars_parentesis_3
