The Forest Elephants of the Central African Republic Are in Peril
In Africa, there are two kinds of elephants: savanna and forest elephants. The species diverged somewhere between two and six million years ago, with the better-known savanna elephants spreading over the plains and open woodlands of Eastern, Southern, and Western Africa while forest elephants stayed behind in the dense forests at the center of the continent. Although the two occasionally hybridize, they are widely viewed as separate species. Forest elephants are smaller, with smaller and straighter tusks. The size of their tusks, however, has not protected them from rampant poaching, because the tusks have a distinctive hue, sometimes known as “pink ivory,” that has made them particularly valuable.
