Nymphargus siren
Nymphargus siren, the Siren Glass Frog, is an elusive and delicate species found only in a few pockets of Andean cloud forest in Ecuador. Listed as Endangered on the IUCN Red List, this tiny frog faces growing threats from habitat loss, climate change, and the degradation of clean mountain streams it depends on for breeding. Because it is highly sensitive to environmental changes, its presence—or absence—serves as a powerful indicator of ecosystem health.
Conservation Goals
Through research, habitat protection, and community engagement, Savia seeks to ensure the long-term survival of this endangered and ecologically important glass frog within the Chontayacu landscape.
Our main goal is to identify all breeding sites, assess long-term population health, seasonal activity, and guide conservation actions that protect both the frogs and the fragile cloud-forest ecosystems they depend on.
Non Invasive Science
Acoustic monitoring offers a powerful, non-invasive way to achieve our goals. Listening to Nymphargus siren allows us to monitor a species that is otherwise extremely difficult to study.Instead of capturing or disturbing animals, researchers simply record the soundscape of the forest and analyze the calls that naturally occur. Each species has a unique vocal signature, allowing scientists to detect presence, track population trends, and monitor breeding activity without ever touching a frog. For sensitive and elusive species like Nymphargus siren, acoustic monitoring provides essential data while keeping the habitat—and the frogs themselves—undisturbed.
