Biodiversité

The IUCN Red List of Threatened Species is essential for practical and theoretical efforts to protect biodiversity. However, species classified as “Data Deficient” (DD) regularly mislead practitioners due to their uncertain extinction risk. Here we present machine learning-derived probabilities of being threatened by extinction for 7699 DD species, comprising 17% of the entire IUCN spatial datasets. Our predictions suggest that DD species as a group may in fact be more threatened than data-sufficient species. We found that 85% of DD amphibians are likely to be threatened by extinction, as well as more than half of DD species in many other taxonomic groups, such as mammals and reptiles.

Protected Planet by the UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) is a staggering achievement of data management that catalogues our planet’s most precious places. The open data platform visualizes and shares detailed geographic data on 250,000 conservation areas around the world, available for anyone to use.
