How satellite data changed chimpanzee conservation efforts

Approximately 345,000 or fewer chimpanzees remain in the wild, according to the International Union for the Conservation of Nature, a substantial decline from the more than two million that existed a hundred years ago. Humans' closest genetic cousins, chimpanzees are an endangered species and scientists and conservationists are turning to the NASA-U.S. Geological Survey Landsat satellites to help bolster their efforts to preserve their forest homes.
