What is a critically endangered species?

Critically endangered species is a species that still exists in the wild, but is listed as the highest risk of extinction. The International Union for Preserving Nature and Natural Resources (IUCN) is an organization that evaluates the risk and decides which animals are considered critically endangered. One of the main factors in defining the species as a critically threat is the speed at which it decreases. If the species population has decreased by 80 percent or more within three generations, IUCN is likely to add it to a critically endangered list. This may also be the case if there is a very strong probability that the type of species will decrease by 80 percent or more over three generations.

To understand what it means, that the species is critically endangered, it is important to understand the spectrum of threat that IUCN uses. The spectrum, which is sometimes also reflected as a red list of IUCN, includes seven categories. The highest category that is called "least concern" is reserved for species to be in very Mthe alema of the extinction. This is followed by a category called "almost endangered", which is used to describe species that are not currently endangered by extinction, but can be in the near future.

three more points on the IUCN spectrum are considered an umbrella of "endangered" species, but the threat differs in its severity. The points in this part of the spectrum include "vulnerable species", "endangered species" and "critically endangered species". One of the key problems concerning these types of endangered animals is that they are in the threat spectrum next to extinct categories. Two extinct categories, which are at the opposite end of the spectrum from "almost endangered" and "least end.ene" are "extinct in the wild" and "extinct".

Critically endangered species on the IUCN list include plants and animals. For example, there are different types of lilies that are considered critically endangered. Among animals that are on the list critically endangerThese species include club frog Togo, Anderson's Salamander, Jaguarundi Gulf, Przewalski's horse and Hawaiian monk seal to name only a few. There are a number of organizations that work to threaten the threat to certain groups of plants and animals less serious.
