The Anthropocene is characterized by unparalleled human impact on other species, potentially ushering in the sixth mass extinction. Yet mitigation efforts remain hampered by limited information on the spatial patterns and intensity of the threats driving global biodiversity loss. Here we use expert-derived information from the IUCN Red List on threats to 23,271 species, representing all terrestrial amphibians, birds and mammals, to generate global maps of the six major threats to these groups: agriculture, hunting & trapping, logging, pollution, invasive species, and climate change. Our results show that agriculture and logging are pervasive in the tropics, and that hunting & trapping is the most geographically widespread threat to mammals and birds. Additionally, current representations of human pressure underestimate overall pressure on biodiversity, due to the exclusion of threats like hunting and climate change. Alarmingly, this is particularly the case in areas of the highest biodiversity importance.
We thank the 1000s of people who participate in the red list. We also thank Dr Simon Stuart for valuable input on the amphibian maps. We thank Prof. Nick Dulvy and Dr Simon Stuart for early input on the approach.
