Long-term monitoring of Darwin's frog populations (Rhinoderma darwinii)
Southern Darwin's frog (Rhinoderma darwinii)
Project Description
ā
Since 2014, we have maintained a long-term monitoring programme of various local populations of the Southern Darwin’s frog (Rhinoderma darwinii) throughout the entire range of this species. We currently monitor four locations: Contulmo (Nahuelbuta Mountain Range), Neltume (Andes Mountain Range), Inio (Isla Grande de Chiloé), and Melimoyu (Aysén Fjords). This long-term project, unique in the study of Chilean amphibians, provides crucial information to understand the dynamics of wild populations of this species. This data is essential for detecting abnormal situations that may threaten its conservation, as well as for designing management and recovery actions for the wild populations of our beloved Darwin’s frog. This project has been fundamental in the development of the Binational Strategy for the Conservation of Darwin’s Frogs.
