Conservation status refers to the level of threat faced by a particular species or ecosystem in terms of its risk of extinction or ecological degradation. It is a measure of how vulnerable a species is to extinction or how endangered it is.

The International Union for Conservation of Nature (IUCN) has developed a widely recognized system of conservation status categories that are used to assess the extinction risk of different species.

The categories range from those organisms that are already extinct to those of least concern.

Least concern and near threatened species, are species that are not presently considered endangered. This means that they are not at immediate risk of extinction but may become endangered if their populations decline.

Examples of least-concern vertebrates include domesticated animals like cows, pigs, and chickens. And common animals like rabbits, squirrels, robins and corn snakes.

Examples of Near Threatened species include large mammals such as the giraffe, cheetah, and hippopotamus. Green sea turtles, Blue-footed Boobies and tiger sharks.

The term "threatened" is used to describe species that are categorized as Vulnerable, Endangered, or Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

A vulnerable species is a species of plant or animal that is at risk of becoming endangered if its population continues to decline. There are currently over 5,000 animals classified as vulnerable. Some examples of vulnerable animals include reindeer, lemurs, polar bears, snow leapards and rockhopper penguins.

Endangered species have a very high risk of extinction in the wild in the near future, and their populations are declining. There are over 3,000 animals classified as vulnerable. Including African and Asian elephants, California condors, tigers, whale sharks and northern spotted owls.

Critically endangered species have experienced significant population declines or have extremely small populations due to various factors such as habitat loss, poaching, pollution and climate change. Without immediate and intensive conservation efforts, they are at risk of becoming extinct. Examples of critically endangered vertebrates include Sumatran orangutans, hawksbill sea turtles, gorillas, Sumatran rhinoceros and the black-footed ferrets.

The final two categories on IUCN Red List are extinct in the wild and extinct. Extinct in the wild organisms no longer exist in their natural habitats and can only be found in captive populations, like zoos and conservation parks. Extinct animals

These species are considered extinct in the wild because they no longer exist in their natural habitats and can only be found in captive populations or through reintroduction efforts. An organism becomes extinct when it no longer exists anywhere on Earth. Examples of extinct organisms include dinosaurs such as the Tyrannosaurus rex, the Dodo bird, the Woolly Mammoth, and the Saber-toothed Tiger.
