Poaching Map (IMAGE) Princeton University Caption Since the 2008 legal sale, illegal ivory production has increased by about 66 percent, while seizures of ivory being smuggled out of Africa have increased by approximately 71 percent. The sale briefly opened ivory trade between China and Japan and four African nations (in dash outlines) -- clockwise from left, Namibia, Botswana, Zimbabwe and South Africa. Elephant poaching, however, has increased all over sub-Saharan Africa, as seen on the map above with red indicating more poaching since 2008 and blue equating to less. The white dots indicate sites for monitoring elephant poaching.
