Abstract

After more than a decade from the first red list of threatened herpetofauna proposal by the Asociación Herpetológica Argentina (2000), we re-categorized snakes from new taxonomic, biogeographical and bio-ecological information as well as methodological changes in the former evaluation. Through the participation of 18 specialists from all over Argentina, 136 taxa of snakes (130 in the previous) were re-evaluated including several taxonomic changes (8 new taxa added to Argentina, and 2 sinonimies). The results were the inclusion of 49 species in the red list (5 Endangered, 17 Threatened, 27 Vulnerable), 15 Insufficiently Known and 72 Not Threatened. Compared to the former categorization of the AHA: one taxon descended from Vulnerable to Not Threatened, 11 Not Threatened and 4 Insufficiently Known were elevated to different categories of threat, 7 taxa were elevated from Endangered to Vulnerable, one from Vulnerable to Endangered. From the 8 taxa not evaluated in 2000, one categorized Not Threatened, 4 Insufficiently Known, one Vulnerable, and 2 Threatened. These changes are the result of: (1) increased systematic, biogeographical and bio- ecological information available for the evaluation, (2) Changes in human pressures on the species or their habitats, (3) methodological changes that included recommendations to apply concepts, discussion and consensus among specialists and the analysis of uncertainties.
