Up to the present in the Danube Delta Biosphere Reserve (DDBR) there were recorded 11 native amphibian taxa (10 species and one hybrid). The first Red List of the wild species from DDBR was drafted in 1999 and printed in 2000. Based on the results of investigations carried out since 2000 and taking into account the developments related to criteria for conservation status of wild species (on world-wide level, on European continental level, on EU level and on national level), the present work provides details on the proposals to consider the following conservations status to amphibians occurring in the DDBR: Triturus dobrogicus (widely distributed, but not frequent species) – Vulnerable; Triturus vulgaris (widely distributed, but not frequent species) – Vulnerable; Bombina bombina (widely distributed, frequent species) - Least Concern; Pelobates fuscus (widely distributed, relatively frequent species) - Least Concern; Pelobates syriacus (a species distributed in the southern part of DDBR and at the limit of the continental plateau)– Vulnerable; Bufo bufo (species occurring only in the proper Danube Delt and less adapted to regularely flooded wetlands with high water-level variations) - Least Concern; Bufo viridis (widely distributed, frequent species, excepting the reed-dominated areas) - Least Concern; Hyla arborea (widely distributed, relatively frequent species) - Least Concern; Rana lessonae (species recorded only in the proper Danube Delt, but probably more frequent than is it known in the present) - Least Concern; Rana ridibunda (widely distributed, frequent species) - Least Concern and Rana kl. esculenta (widely distributed, frequent amphibian) - Least Concern.
