What's Left

Six emblematic species, a crowd of icons that shrinks or rebuilds, census after census.

Tiger, black rhinoceros, giant panda, mountain gorilla, vaquita, European hamster: these emblematic species have been tracked for decades by conservation bodies that regularly survey their wild population. Each new census is an estimate, sometimes accurate to within a handful of individuals, of how many actually remain in the wild.

This page follows these species through their successive censuses, each one represented by a crowd of icons that grows or shrinks over time. The story isn’t one-directional: alongside the decline of the vaquita or the European hamster, the giant panda and the mountain gorilla show that recovery remains possible.
