Perhaps as few as eighty thousand forest elephants remain in the Central African Republic. The story of these declining numbers is also a story of habitat destruction. Where forest elephants exist in an undisturbed state, they build networks of trails through the deep forest. These trails connect mineral deposits, fruit groves, and other essentials of forest-elephant life. In Central Africa, there are dozens of fruit trees whose seeds are too large to pass through the guts of any other animal and for which forest elephants have evolved as the sole dispersers. These trees line the forest-elephant paths. Where elephant populations are disturbed, the paths disappear.

How to Write About a Vanishing World

The losses on our human-dominated planet keep coming, and so, too, do the stories. These days, it’s not just species that are vanishing. Entire features of the earth are disappearing—thus, the latest batch of “witness-to” books, written by geologists.

On the Brink: African Wild Dog

Poachers use wire snares in many parts of Africa to trap wild antelope, but collateral damage occurs too. African wild dogs, one of the world’s most endangered mammals, are often caught by these snares. Due in large part to this poaching practice, the population of African wild dogs has dropped by 90 percent – to 6,660 – in the last century.  

So, zoologist Brandon Davis and his team formed the Painted Dog Protection Initiative and designed specialized collars to protect the animals from these deadly entanglements.

The African wild dogs’ susceptibility to snares arises largely from their social nature. They are pack animals that move in groups and look after one another.

“They will lick the wounds of the injured,” Davis said, explaining that these animals are “one of the few species that actually care for their injured.”

When one wild dog is snagged by a wire snare, others will return to care for the packmate, and then get trapped or injured as well. If enough traps are present in a snare line, an entire pack can be caught.

Wire snares are lightweight and low cost traps, so they are easy to obtain and use. It takes only a light touch to trigger the wire loop to tighten down on the animal’s neck.

Davis’ team noticed tracking collars – used in research to keep tabs on a wild dog’s location – helped animals caught in snares to avoid suffocation. So, the team built custom collars with rivets and clips that allow a trapped animal to breathe and break free.

Now that testing is completed, the Painted Dog Protection Initiative plans to deploy ten collars with wild dogs living in at-risk packs in Zimbabwe. They aim to build 100 additional collars, which could protect 20 percent of the wild dog population in Zimbabwe.

On the Brink: Pangolins

Pokémon fans should be familiar with the pangolin. The scaly plates of this real-life critter inspired the armored, roly-poly defenses of the sandshrew Pokémon.

Though the scales and somersaults protect pangolins from hungry predators, such as lions, these mechanisms can’t save them from humans. To date, pangolins are the most trafficked mammals in the world, according to “The Global Trafficking of Pangolins,” a 2017 report by TRAFFIC (a wildlife trade monitoring network). The number of pangolins remaining in the wild is unknown, but scientists estimate populations dropped up to 80 percent in the last decade.

“Poachers simply find them, pick them up, and send the off to their dooms,” Paul Todd, a senior staff attorney with the NRDC’s Wildlife Trade Initiative, told the PBS NewsHour via email. “The defenses that have evolved over millions of years do absolutely no good when faced with the threat posed by people.”

Pangolins are native to Asia and Africa, and they’re the only mammals adorned with scales. Todd said in 2017, African authorities confiscated almost 50 tons of pangolin scales. In April and May, law enforcement in Vietnam and Taiwan confiscated 20 tons of scales shipped from Africa. Between 2010 and 2015, authorities around the world made a total of 1,270 pangolin shipment seizures. But Todd and other experts believe the actual numbers are higher because, according to the TRAFFIC report, some countries reported more pangolin trafficking than seizures.

“Remember that these are fairly small animals, like the size of a small to medium dog, so a ton in weight of scales or other parts can represent thousands of individual animals,” Todd said.

Even though Asia has its own species of pangolins, African pangolins are imported to Asia in droves due high demand for their scales and meat.  Nearly 70 countries play a role in the illegal pangolin trade, according to a report by TRAFFIC. This list includes the U.S., China, Germany, Vietnam, Thailand, Belgium and Malaysia. Mongabay reported in May that all pangolin parts are in high demand, mostly in Asia. Pangolin meat is a delicacy, their skin is used in leather materials, and their scales are used in traditional medicine.

Pangolins play vital roles in their ecosystems by cultivating soil and managing insect populations. A pangolin consumes millions of ants and termites every year. Losing them could mean serious pest infestations in their habitats.

But hope for the pangolin exists. The PBS NewsHour reported in 2016 that CITES (an international group in charge of wildlife trade) banned international pangolin trade. Pangolin trafficking still occurs, but this ban has lowered the demand for pangolin scales and meat. Todd said the U.S., China and other countries involved in pangolin trade have stepped up enforcement under the ban.

“But there’s a lot more that needs to be done,” Todd said. “It’s entirely within our power to erase the species forever, and so it’s also our duty to make sure that doesn’t happen.”
