The primary extinction drivers and the sum of extinction drivers for (a) all 18,016 terrestrial vertebrate species together and separately by terrestrial vertebrate group: (b) amphibians, (c) reptiles, (d) mammals, and (e) birds. The total number of species threatened by each extinction driver for those classified as near threatened or worse by the International Union for the Conservation of Nature is shown in decreasing order for all terrestrial vertebrates. Threat order is the same (from the all‐species analysis) in all graphs to facilitate direct comparisons between groups (y‐axes values vary in range based on the number of species)
