One-quarter of mammal species [are threatened](https://ourworldindata.org/grapher/share-threatened-species) with extinction. Indonesia is home to nearly 200 of these species. In contrast, Sweden has only one, and Finland only two at risk. If we’re to protect and conserve the world’s mammals from extinction we first need to know where they’re most threatened. In our **related post** we saw how the diversity of mammal species varies across the world, and where the biodiversity hotspots are. But does this also reflect where mammals are most under threat? ## Where are **endemic** mammal species at risk of extinction? In the map we see the number of endemic mammal species which are threatened with extinction in the wild.{ref}Species are defined as ‘threatened’ if they’re classified as Critically Endangered, Endangered, or Vulnerable on the [IUCN Red List](https://www.iucnredlist.org/).{/ref} It looks very similar to the [map of endemic species](https://ourworldindata.org/grapher/endemic-mammal-species-by-country). Indonesia has the most endemic mammals threatened with extinction: 132 species. This means 45% – nearly half – are under threat.{ref}The map presents threatened species in _absolute_ numbers. Some may argue that they should instead be presented in relative terms i.e. the percentage of species which are threatened. After all, reporting absolute numbers tends to make countries with a larger number of endemic species look worse: countries with more endemics tend to have more threatened endemics. We should be aware of this. But here I think absolute numbers provide the more useful metric: if we want to protect and prevent the world’s mammals from going extinct, we need to know where the largest number are threatened and why. To do this, we need absolute numbers.{/ref} Madagascar is second on the list, with 129 (61%) species threatened. Australia – despite having the second largest number of endemic mammals – has much fewer at risk: with 54 endemics (1-in-5) at risk of extinction. Mexico, Brazil and India also have more than 25 threatened endemic species. <Chart url="https://ourworldindata.org/grapher/threatened-endemic-mammal-species"/> ## Where are **total** mammal species at risk of extinction? It makes sense to be most concerned about endemic species, or those with a very small geographical range. Once they are lost from these specific areas, they are lost forever. But of course that doesn’t mean we should ignore non-endemic species. In this map you can explore the total number (endemic and non-endemic) of mammal species threatened in each country.
