Valcheta frog and its clutch.

The Laguna-Raimunda Frog (Atelognathus reverberii) is an IUCN-Vulnerable species, endemic from northern Patagonia steppe in Argentina. Distributional range of this frog is restricted to about 100 meters of the bank of temporary and isolated lagoons placed over a volcanic plateau at more than 800 m elevation. This frog is facing decline in extent and quality of its habitats due to extreme weather and the trampling of lagoons by livestock. In previous researches, we observed that the species is highly infected by Chytrid fungus and we also recorded that local human inhabitants dig water pits on the shores of lagoons, promoting the death of hundreds of frogs, which enter inside the pits for reproduction, but then drown in their attempts to get out. Throughout this project we will conduct research, awareness raising activities and management aimed at improving the conservation of this species, as a continuation of the work started in our previous RSG. We also will extend our work to include the Valcheta Frog (Pleurodema somuncurense), an IUCN-Critically Endangered species also endemic from Somuncura plateau.

In order to improve the conservation of this frog, we will work for the achievement of the following objectives:

1) update knowledge on range of this species by conducting exhaustive surveys searching for new populations;

2) assessing how to better allocate conservation efforts by studying effect of threats;

3) monitor and maintain two sanctuaries created in frame of a previous RSG;

4) improve frogs’ habitats by fencing parts of some lagoons to impede the entrance of livestock and, after fenced, recover native vegetation that individuals use as shelter;

5) implement a system of fences, escape ramps and covers on water pits dug by local people to impede the death of frogs;

6) continue conducting awareness raising activities to inform about the importance of protecting Laguna-Raimunda Frog and Valcheta Frog;

7) write a Conservation Action Plan for both species.
