Understanding the biodiversity of our planet is critical for developing conservation strategies. This series of datasets shows the biodiversity of birds, mammals, and amphibians. Said simply, these maps show how many kinds of birds or mammals or amphibians live in each area around the world. These maps look at just the animals on land and don’t include any marine animals. Also included are corresponding maps of where the threatened species live, the ones at greatest risk of extinction. Knowing where these threatened species live can help direct conservation efforts to ensure that the places with the most vulnerable species are being protected.
The species data for this dataset comes from the International Union for Conservation of Nature. Roughly 41% of amphibians are classified as threatened with a high risk of extinction. Amphibians are more extreme than the other vertebrate groups in that many of them are restricted to very small distributions, sometimes only a few square miles. As a result, even though nearly half of the world’s amphibians are shown in this map, they occur in just a tiny fraction of the land surface. These are the places where conservation is urgently needed to save these amphibians from extinction.
