Since 2021, the Park has launched a study to find out more about this little amphibian!

How is he doing? What are its numbers?

Here are some initial answers:

▪ The first phase of the study therefore began in 2021, within Natura 2000 sites in order to identify areas potentially favorable to the presence of the Yellow-bellied Ringer and its reproduction. This first field phase unfortunately did not reveal any new favorable areas, only those already known in the Park were confirmed.

▪ In 2022, all of these areas were surveyed as part of an inventory of the species. From March to July, 7 field sessions were carried out in order to detect as many individuals as possible. 

▪ Thanks to the work of our intern, Gautier Duchenet, 294 individuals were observed on the identified sites!

▪ Among these individuals, a very high percentage was still sexually immature thanks to an exceptionally rainy summer of 2021: 82% of individuals were juveniles and only 18% adults.

▪ But in the future, with repeated drought phenomena, which begin earlier and earlier, the rate of reproduction success of the Yellow-bellied Ringer will be impacted and could, ultimately, lead to the disappearance of the species on the Montagne de Reims.

▪ The repeated passage of two wheels or motorized vehicles in areas favorable to this species also causes disturbance. The involvement of sports event organizers is therefore essential to protect this species.

In order to consolidate the results of the study and monitor this species, surveys will be renewed over the next three years. The results presented here are therefore only trends for this first year.

We will keep you informed of the rest!


The engineering and the internship are co-financed by Europe (FEDER) and the State.

“Animation of Natura 2000 sites 26 and 67 2021/2022” is co-financed by the European Union.

Europe is committed to Champagne-Ardenne with the ERDF/FSE/IEJ Champagne-Ardenne Operational Program 2014-2020 / European Regional Development Fund
