Over the cause of many millennia, there have been plenty of extinction events. Five, to be exact. However, many believe us to be living in the sixth extinction event caused by human activity. To illustrate this point, we have looked at data from the OECD that shows the number of endangered species by country.

We have created multiple charts to show the data more accurately.

Also included in this article will be answers to multiple questions regarding endangered species. How many endangered species there are, what the number of endangered species is for every country, what the most endangered species are, and more.

The data for species in the endangered species charts include:

  • Mammals
  • Birds
  • Reptiles
  • Amphibians
  • Fish
  • Vascular Plants
  • Mosses
  • Lichens
  • Invertebrates

As you can see in the chart above, the number of endangered species by country is very high. The Czech Republic has the most endangered species with 1,905. However, only a small portion of these (~200) is actually (non-invertebrate) animals. The rest of the staggering amount comes from invertebrates (a whopping 1,173) and some plant & moss species.

Some examples of invertebrates include:

  • Squids
  • Insects
  • Spiders
  • Clams
  • Sea urchins
  • Whales

How Many Endangered Species Are There in 2022?

There are over 18,000 species on the endangered species list as of 2022. There are many more on the IUCN red list. Keep in mind, that this includes both plant and animal species.

This number is way up from last year and continues to grow.
