Species at risk are all those considered critically endangered, endangered or vulnerable by the International Union for Conservation of Nature and Natural Resources. In 2004, 15,503 species were assessed as at risk of worldwide extinction. Mapped here are animals and plants assessed as being locally at risk of extinction.
The islands of Mauritius and Madagascar have the most at risk species living there as a proportion of all local species assessed. The highest counts of species at risk are in Ecuador, the United States and Malaysia. In Ecuador 2151 species including many plants and 163 amphibians were classed as ‘at risk’.
