As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.
Additionally 1193 amphibian species (16% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
A type of leaf-eating langur that has an unusually long and bushy tail with white hips. It is also one of the most endangered primates in the world. Only about 300 Delacour's langurs are alive today, and experts fear they could be completely extinct if the current rate of decline continues.

The ASG is a global volunteer network of dedicated experts who work to provide the scientific foundation for effective amphibian conservation action around the world. The ACAP (Gascon et al 2007), concerned that time and capability were short, recommended that all relevant species be immediately incorporated into ex situ breeding programs . [ 48 ]
The following is a list of'amphibians found in Hoàng Liên National Park' in northern Vietnam. The list is based on Tapley, et al. (2017). The list is based on Tapley, et al. (2017).

Of all evaluated amphibian species, 10% are listed as vulnerable. No subpopulations of amphibians have been evaluated by the IUCN. For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild".
