Inventory and complementary areas for the conservation of the birds of Entre Rios Province, Argentina

The Neotropical region is characterized by the high species richness of birds, whose protection and inventories show biases due to lack of geographic representation and species diversity. In Entre Rios province its protected areas have not been well established, generating biases in biodiversity representativeness. We updated the birds' inventory of Entre Rios with 80,000 records. The province was divided into 39 cells of 0.5 degrees lat-long to analyze birds' richness and priority areas through a complementary analysis. The Protected Areas (PAs) system was overlapped with the complementary areas to detect gap conservation areas. Entre Rios presents 396 bird species and needs 10 cells to protect them all. The priority areas included cells on the Parana and Uruguay rivers. These priority areas overlap poorly with the current PAs system. We recommend the creation of new PAs or change the protection categories of PAs that overlap with priority areas selected. This work revaluates the importance of updated inventories to perform spatial prioritization and contrast the current PAs system to generate representative and efficient systems.
