Research and Conservation Priorities for The Ryabov’s mossy frog Theloderma ryabovi in Vietnam

Mossy Frogs of the genus Theloderma are particularly well adapted to their environment due to their coloration and warty appearance, which allows them to hide from potential threats. Despite its good camouflage, it is nevertheless threatened by poaching for trade, habitat loss and tourism. Theloderma ryabovi is microendemic to Vietnam and is listed as endangered (EN) on the IUCN Red List. However, it is not listed in Vietnam's Red Data Book and is not protected by law. This project aims to provide scientific evidence for the authorities to consider listing Theloderma ryabovi in key conservation documents and take urgent conservation actions.  It also aims to improve the understanding of the distribution, habitat use, breeding habits and threats of Theloderma ryabovi. This is particularly important as only a few individuals of this species are yet known to exist in a small and unprotected area.  Following the One Plan Approach, the project also plans to set up an in-country conservation breeding programm.

In addition to this project, Stiftung Artenschutz is supporting the mossy frogs through the latest EAZA campaign "Vietnamazing".
