Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.
In crisis
This frog is under threat due to the large human population.
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
