Among the remarkable findings was the harlequin frog (Atelopus seminiferus), once thought to be disappearing from the area. Biologist Trond Larsen was astonished to spot the elusive amphibian in an unexpected lowland habitat.
‘I almost couldn’t believe it,’ he said to Conservation International on the Harlequin frog. ‘Not only is this frog endangered, but this species has never been found this low on the mountainside. It was our first important discovery — and it was a harbinger of more to come.’
The 38-day research mission, part of Conservation International’s Rapid Assessment Program, documented over 2 000 species of plants and animals, including four new mammals and 49 species threatened with extinction. Notably, the team identified a rare amphibious mouse and dung beetles thriving in previously deforested areas.
With deforestation threatening the region’s ecosystems, researchers emphasize the importance of sustainable conservation. By working alongside Indigenous communities, they aim to establish protected corridors to safeguard this extraordinary wildlife.
