Notes: This map depicts the number of endangered species in each US state. The data in this map are based on the International Union for Conservation of Nature’s Red List of Threatened Species which classifies organisms by their risk of global extinction. The species used to create this list are categorized as either Endangered or Critically Endangered. The data were pulled from the Global Biodiversity Information Facility which houses publicly available species occurrence data from citizen science projects such as iNaturalist and eBird as well as institutional and governmental surveys. This map includes animal, fungi, and plant species found in both terrestrial and aquatic ecosystems. I created an older version of this map around two years ago and thought that it was due for an upgrade. I released this map today since it's the 50th anniversary of the signing of the US Endangered Species Act into law. We've come a long way, but there is still more to be done in the way of protecting species from extinction. As always if you have any praise, constructive criticism or questions, let me know! I love hearing from you all! Remember to be kind to others and as always stay awesome Reddit!
