Red pandas have been recorded to use steep slopes of more than 20° and stumps exceeding a diameter of 30 cm (12 in). [50] [52] Red pandas observed in Phrumsengla National Park used foremost easterly and southerly slopes with a mean slope of 34° and a canopy cover of 66 per cent that were overgrown with bamboo about 23 m (75 ft) in height.

The Red List Index (sampled approach) (SRLI) has been developed in order to determine the threat status and also trends of lesser-known and less charismatic species groups. It is a collaboration between IUCN members and is coordinated through the Institute of Zoology (IoZ), the research division of the Zoological Society of London (ZSL).
Endangered (EN) – very high risk of extinction in the wild, meets any of criteria A to E for Endangered. Vulnerable (VU) – meets one of the 5 Red List criteria and thus considered to be at high risk of unnatural (human-caused) extinction without further human intervention. Near Threatened (NT) – close to being endangered in the near future.
The current extinction crisis is witnessing extinction rates that are occurring at a faster rate than that of the natural extinction rate. It has largely been credited towards human impacts on climate change and the loss of biodiversity. This is along with natural forces that may create stress on the species or cause an animal population to ...
Conservation status for warm-water reef-building corals was analysed for the International Union for Conservation of Nature’s (IUCN) Red List. 44% of warm-water coral species facing extinction ...
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 474 endangered mammalian species. [1] Of all evaluated mammalian species, 8.6% are listed as endangered. The IUCN also lists 86 mammalian subspecies as endangered.
Critically endangered (CR) species face an extremely high risk of extinction in the wild. 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.
Version 2014.2 of the IUCN Red List of Threatened Species identified 4574 critically endangered species, subspecies, varieties, stocks, and subpopulations.
