Africa's elusive forest elephants are disappearing

The clock is ticking to save Central Africa's forest elephants. Populations of the elusive elephants have plunged by around 80 percent inside one of the region's most important nature preserves. Within Gabon's Minkébé National Park, poachers likely killed about 25,000 forest elephants for their ivory tusks between 2004 and 2014, according to a Duke University-led study in the journalCurrent Biology.SEE ALSO: The world's fastest land animal is even more threatened than we thoughtTha
