Species at Risk

Trying to get a picture of where and how many species globally are endangered or even at risk of extinction is a difficult undertaking. For 50 years the International Union for Conservation of Nature (IUCN) publishes the red list of threatened species. The list is a “comprehensive information source on the global conservation status of animal, fungi and plant species and their links to livelihoods”. It contains over 77,000 species of which according to the most recent report more than 22,000 are at risk of extinction. IUCN considers species at risk when they are “critically endangered, endangered or vulnerable.
Mapped here is data from the International Union for Conservation of Nature’s (IUCN) Red List of threatened species including endangered and vulnerable species. The main cartogram shows countries resized according to all animal and plant species assessed as being at risk of local extinction. The two smaller cartograms highlight that conservation efforts have very different spatial degrees of severity, which also partly reflects the different geographical distribution of species.
