Cheetah numbers in alarming decline as African habitat shrinks

Amid population declines for many wildlife species in Africa, conservationists are sounding alarm bells for the cheetah, the fastest animal on land.

An estimated 7,100 cheetahs remain in the wild across Africa and in a small area of Iran, and human encroachment has pushed the wide-ranging predator out of 91 percent of its historic habitat, according to a study published on Monday.

Consequently, the cheetah should be defined as "endangered" instead of the less serious "vulnerable" on an official watch list of threatened species worldwide, the study said.
