Cracking Down on Poaching of Endangered Species, CSI-Style
African elephants and tigers are faced with extinction, in large part due to poaching. That’s the disheartening news coming out of the Convention on International Trade in Endangered Species, or CITES, meetings underway in Qatar.
As for elephants, Tanzania and Zambia are petitioning CITES to “downlist” the mammal’s conservation status so they can legally sell stockpiled ivory. The countries say the prized tusks come from elephants that died naturally or were seized from poachers. “But conservationists argue that over the past decade illegal poaching has risen steadily, and if the elephant is downlisted in some African nations it could have a devastating impact for the species as a whole,” Time reports.
The situation is even more dire for tigers. Willem Wijnstekers, secretary general of CITES, said the world has “failed miserably” at protecting the creatures, which are on “the verge of extinction,” the AP reports. In order to conserve the 3,200 remaining wild tigers, Wijnstekers says countries will have to develop conservation strategies and cooperate with international agencies to halt poaching and the illegal tiger products trade.
One approach that might help crack down on illegal killings of these and other endangered animals involves DNA analysis. The technology is already being tested on the ground. While the technology is still improving, in the near future anyone from biologists to law-enforcement officials might be able to plop a bit of tissue into a handheld device and tell which species it came from.
Audubon’s Susan Cosier recently covered the technology, and its potential affect on endangered species conservation:
Gorilla. Duiker. Mandrill. The six fingernail-sized pieces of dried, smoked meat ready to be analyzed on the warped table in an impromptu lab in the Cameroonian jungle could belong to any, or none, of these animals. That’s what Sarah Burgess-Herbert, a biologist at the Zoological Society of San Diego, California is here to find out. Using minimal equipment, Burgess-Herbert is testing whether she can extract DNA sequences, or bits of genetic information called barcodes, from these samples confiscated by Cameroon’s Ministry of Forestry and Wildlife. Then she’ll try to identify their origin. It’s a process that’s easily done in a traditional laboratory, but it’s a challenging feat in this remote locale, where sterile space, supplies, and equipment can be hard to come by.
If the experiment is successful, the portable laboratory could help to crack down on the illegal bushmeat trade. Not all wild animal meats are illegal to sell, but with more logging, roads, and access to previously untouched areas, hunters can reach rare, exotic wildlife, which end up in the market. Instead of sending meat samples elsewhere to be tested, a mobile test kit could help local authorities better track which species are being sold illegally as bushmeat, and provide evidence to prosecute providers of these illicit victuals. Burgess-Herbert is just one researcher in an international effort to curtail the bushmeat crisis using forensic genetics.
