This indicates that the species is not critically endangered, but is facing a very high risk of extinction in the wild in the near future. This is due to an observed, estimated, inferred or suspected reduction in population of at least 50% over the last 10 years or three generations, whichever is the longer, based on a decline in area of occupancy, extent of occurrence and/or quality of habitat, as well as actual or potential levels of exploitation.

For the same reasons, a reduction in the population of at least 50% is also projected or suspected to be met within the next 10 years or three generations, whichever is the longer.
