The IUCN Red List is the world's most comprehensive source of information on the extinction risk of animal, fungi and plant species. It classifies species into nine categories, from Not Evaluated to Extinct, and provides data and news on biodiversity conservation.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change .
- Javan Rhinos. Once found throughout south-east Asia, Javan rhinos have suffered a staggering decline in their numbers due to hunting and habitat loss.
- Amur Leopard. The Amur leopard is one of the rarest big cats in the world, with only around 100 individuals left in the wild. Although their wild population seems to be stable and increasing, these leopard subspecies are still critically endangered since 1996.
- Sunda Island Tiger. The Sunda Island tiger, or the Sumatran tiger, is the smallest tiger subspecies in the world, weighing up to 140kg. For reference, the tigers that live in the Amur region are the biggest of all the big cats where males can weigh up to twice as much as Sunda Island tigers.
