Lions have disappeared from North Africa and southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru. The lion is now a vulnerable species. There was a decline in its African range of 30–50% over two decades in the second half of the 20th century. Habitat loss and conflicts with humans are the greatest causes of concern.
