Conservation Status for Photographed Wildlife

You've probably heard of the Red List. The IUCN, the International Union for the Conservation of Nature, produces this list. The IUCN Red List of Threatened Species. A lot of species are endangered or almost extinct. The Red List is needed to focus on the conservation of the right species.
I've added the Conservation Status for wildlife I photographed. With every species and subspecies in my Biological Classification menu (see the menu on the left as well). You can see the little icon if you go down to the species and subspecies level. If you hover over it with your mouse, it has a tooltip text explaining the icon, e.g. "Conservation status: Near Threatened". And at the bottom of that page you can find some stats about the number of animals with a certain Conservation Status.


Species are classified in nine groups, set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation.

  • Extinct (EX) - No individuals remaining.

  • Extinct in the Wild (EW) - Known only to survive in captivity, or as a naturalized population outside its historic range.

  • Critically Endangered (CR) - Extremely high risk of extinction in the wild.

  • Endangered (EN) - High risk of extinction in the wild.

  • Vulnerable (VU) - High risk of endangerment in the wild.

  • Near Threatened (NT) - Likely to become endangered in the near future.

  • Least Concern (LC) - Lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

  • Data Deficient (DD) - Not enough data to make an assessment of its risk of extinction.

  • Not Evaluated (NE) - Has not yet been evaluated against the criteria.

When discussing the IUCN Red List, the official term "threatened" is a grouping of three categories: Critically Endangered, Endangered, and Vulnerable.
