Sixth-Remaining Northern White Rhino Dies

The species faces extinction, with only five of its kind left on Earth.

Angalifu, a northern white rhino housed at the San Diego Zoo's Safari Park, has died of old age at 44. With his death the subspecies draws closer to extinction, as only five remain.

Angalifu was housed at San Diego Zoo with another elderly northern white rhino named Nola. The pair, however, was not able to produce offspring, and the outlook for babies elsewhere looks grim.

All hopes for offspring rest with a single male named Sudan living on a reserve in Kenya with two females. Dvur Kralove Zoo, in the Czech Republic, meanwhile, is home to one elderly female.

The northern white rhino has been brought to the brink of extinction by poachers, who kill the animals for their horns, which are sold in markets in East Asia, where rhino horn is believed to have medicinal value.

There’s no silver bullet solution to protecting endangered species. We can't stand guard over every single one of them, as this man is doing to protect black rhinos in Zimbabwe. But technology can be helpful in staying ahead of wildlife poachers who have been winning the war for too long, according to Crawford Allan, a senior director based at the World Wildlife Fund for a large international wildlife trade monitoring program called TRAFFIC. Here’s a look at their arsenal.

One of the first technologies rolled out consistently to monitor wildlife, camera traps were catching poachers in the act. They’ve since evolved into tinier, almost impossible to detect digital devices. Some have live video feeds, automatic triggers, remote access, heat sensing, vibration detection and are smart enough to triangulate shotgun sounds so park rangers know exactly where to go.

Wildlife conservationists need to know where the animals are in order to protect them. Radio-frequency identification tags are an important tool, WWF’s Crawford Allan said. RFID chips implanted in rhinoceros horns connect to ground or mobile sensors so when one falls off the grid, a team can work on tracking it down and check the animal's welfare. The tags work for other species, as well. Here, two Canada Lynx kittens are tagged by rangers from the US Fish and WIldlife Services.

Getting a visual on poachers before they strike is tall order. Masts with static night vision cameras are used to keep an eye out, but the image angle and range are limited, according to Allan. Light aircraft are expensive, require a pilot, need runways and could be shot down. For these reasons, unmanned aerial vehicles are emerging as a potential solution. Cost is still an issue but poachers can’t hide easily from UAVs with thermal detection patrolling the skies.

Mesh networks are digital communications systems originally developed for the military, Allan explained. With help from a $5 million Google grant, WWF is installing a mesh network to relay sensor and device data. Rangers on the ground can also use the network to communicate without poachers being able to listen in.

Satellite technology has transformed basic tracking collars. Accelerometers inside can indicate whether the animal is well, sick or has died given its motion and the satellite connection means the animals are easier to locate. The collars can be used on a wide range of animals, from birds on up to elephants. Allan said the price has been prohibitive for developing countries, so he hopes it will come down.

The Spatial Monitoring and Reporting Tool, known as SMART, is a free open-source software created by a community of conservation organizations. Available in local languages, the software is designed to make wildlife conservation activities and wildlife law enforcement patrols more effective. Tracking animals, patrols and vehicles means an influx of data, and SMART can crunch it all to show stakeholders the big picture.

In India, the illegal metal snares used to catch tigers were being cleverly camouflaged. To fight back, the TRAFFIC wildlife trade monitoring network trained forest guards to use robust, easy-to-assemble Deep Search Metal Detectors. “Word kind of got around that there was some sort of magic technology out there that was going to find every poacher in the forest instantly,” Allan said.

In South Africa, the Rhino DNA Index System or RhODIS project has unique DNA profiles for individual rhinos. If one is killed for its horn, the database aids in prosecuting poachers. Wildlife forensics has such a high degree of resolution now that DNA testing can actually show which country in Africa confiscated ivory came from, Allan said. Here, a tiger cub is donating a blood sample for DNA sequencing.
