FIGURE 5.

Number of nonthreatened (NT) and vulnerable (VU) and endangered (EN) and critically endangered (CR) terrestrial vertebrate species threatened by various extinction drivers (e.g., agriculture, logging, invasive species native species and disease) (white dot, median; thick black line, interquartile range; thin black line, 1.5 × interquartile range). The number of extinction drivers for each species is the total number of primary threat types as listed by the International Union for the Conservation of Nature (IUCN) for taxa that are near threatened or worse. The sum of extinction drivers for near threatened and vulnerable species and for the sum of extinction drivers for endangered and critically endangered species were grouped together
