Somewhere in the Kruger National Park, Cole du Plessis steps out of his vehicle, and slowly waves a contraption that looks like a TV antenna. He watches a small digital display on a handheld device. Suddenly, it pings. He moves around. It pings twice.
“We’ve got signal,” he says with quiet satisfaction.
But he’s not talking about a cellphone signal. He’s just used a receiver that picks up VHF signals – low-power, short-range radio waves. The transmitter is fixed to a tracking collar that has been attached to an African wild dog – South Africa’s most endangered large carnivore. Du Plessis works for the Endangered Wildlife Trust (EWT), with the unique title of national wild dog meta population coordinator.
Cole’s focus on this single species is testament both to its endangered status – there are fewer than 500 surviving in South Africa – and the special nature of the animal. It’s one of the most socialised of all wild animals, with a highly structured social order, a collective style of hunting and an orderly approach to feeding on a kill, with the young always feeding first.
It is also one of the underdogs of the wild, with what the EWT calls “a mistaken reputation for attacking livestock”, which results in them being persecuted by humans as much as by lions. That’s aside from its susceptibility to poachers’ snares and even road accidents.
A combination of human and natural threats have resulted in the wild dog going extinct in 23 countries of Africa, and there are fewer than 5000 on the entire continent. That makes it even rarer than the rhino, which has become the poster animal for endangered wildlife.
Help is at hand, however, and technology is playing a major role in attempts to bring the species back from the brink of total extinction.
The EWT’s Kruger Rare Carnivore Program is a major project to investigate threats to wild dogs and factors affecting their numbers, as well as to track their movement in the Greater Kruger ecosystem.
Du Plessis previously worked with Wildlife ACT in kwaZulu-Natal, using telemetry to track and locate wild animals in smaller reserves. In smaller reserves, intensive monitoring was possible, as well as necessary, due to the proximity of local communities living around the reserves. The challenge in the Kruger Park is very different, largely due its size.
“In smaller reserves, VHF gives you the luxury of getting live tracking data every day,” says Du Plessis, who has a Masters degree in protected area management. “In the Kruger and in the Gorongoza in Mozambique, the rural nature of the area and the lack of road access means that, to find wild dogs, you have to use satellite collars with GPS devices fitted. So you have luxury of sitting on computers at home or the office and tracking them. The problem is, the more GPS data you want to download, the shorter the collar battery’s duration.”
He points out that animal tracking technology does not have the luxury of GPS tracking on cellphones, which have their batteries charged by human beings every day.
“There are three categories of collar: VHS is very old tech but very reliable, and uses very high frequency radio telemetry. GSM collars works off the cellphone network, have SIM cards built in, and relay information through cellular signals, based on proximity to a tower or handheld device.
“The third collar is the best type, using GPS, and there are different types. We traditionally used Sirtrack, a New Zealand company which developed satellite tracking collars for wildlife. But they cost around R55-60 000, so we couldn’t use too many. In KZN and Kruger we use all these categories of tracker.”
Fortunately, tracking collars are now being manufactured locally by African Wildlife Tracking, at half the cost of the imported versions.
David Marneweck, manager of the EWT’s Carnivore Conservation Programme, points out that the objectives for putting on the collar determine what technology is used.
“The more often we ask the collar to relay data, the shorter the battery life. If we want data once a day, it lasts a year and a half. If you’re doing a coarse study on habitat use, once a day is fine, but if you want to vaccinate a population, once every six hours makes more sense, and battery life is affected accordingly.”
When Du Plessis or other members of the world dog project pick up a signal, they are able to home in on the general location of a wild dog pack. Usually, due to the cost and complexity of collaring a dog, the focus is on the alpha male in each pack. This means that the entire pack can be tracked, even if only one dog is collared.
The collars have to be checked regularly, and the batteries replaced, and this can only be done by darting the animal to sedate it. Sometimes, it can take several days to track down a single wild dog. In the process, however, the team regularly comes across animals in distress.
During an expedition with the wild dog tracking team coordinated by Vodacom, we receive an urgent call: members of the team have come across an elephant caught in a poacher’s snare. It’s a crude wire trap, but it has cut deep into the elephant’s leg. The Kruger Park’s state vets are called, and they are quickly on the scene to sedate the animal, remove the snare and treat its injuries.
A few hours later, we finally find one of the elusive wild dogs. It is sedated, collar and battery checked, and after a few minutes the beautiful animal staggers to its feet and hobbles away.
Among the observers is John Mitchell, coach of the Vodacom Bulls rugby team. He is there with several of his players to see the tracking project in action. It is not a mere public relations exercise, though. Mitchell uses the wild dog as a metaphor for the strategies he has used to transform the team in the past year.
“They are not only underdogs, but they work as a team, win as a pack, and support each other even in most dangerous circumstances,” he explains. “Even if one is injured, it is never abandoned.”
Mitchell and his team are participating in the Vodacom Red Wild Dogs tour, part of a campaign that gives Vodacom Red clients a chance to win a once in a lifetime experience, based on their personal interests. The small group on this tour all combine a passion for rugby with a strong interest in wildlife.
Mitchell and the group watch with admiration as the tracking team and the vets, too, work in close cooperation. The vets and the wild dog tracking team have a symbiotic relationship, and it is clear that a deep mutual respect exists between them.
“Just implementing technology doesn’t mean you’re going to be successful,” says Marneweck. “You still have to use your expertise to achieve your goal, and to get wild dogs immobilised ethically and effectively within a reasonable period of time.”
Given the rapid advances in cellular, radio and satellite technology in just the last five years, one would expect tracking to become far easier and cheaper. Marneweck insits they have tried it all, and the advances that aid cellular connectivity still do not offer the range or battery efficiency that makes it practical for wildlife tracking across a vast area like the Kruger.
“Everything is based on battery life, and we’ve tried everything from kinetic technology to solar technology, like small solar panels. It’s a great idea, and we use it for vulture backpacks extremely successfully; it can last seven years. With dogs, however, they roll in the mud and get dirty. The panels fill with dirt very quickly and become useless.”
The benefits of tracking are massive.
“Without collars, wild dog conservation would not have been possible,” says Du Plessis. “Today is a case in point. It was so hard to find. Imagine if they didn’t have collars, it would have been impossible. As ugly as some people think collars are, wild dogs have been saved from snares by anti-snare plates fitted to the side of the collar, which absorbs the force of snare.”
The current project is a collaboration between SANparks, the state veterinary authority and the EWT. It started in July 2016, after an outbreak of canine distemper virus wiped pout a pack of wild dogs in the Kruger. The project is both a health survey and a targeted vaccination of wild dogs, to understand the threat and protect the animals from disease.
Next week it will have been running for two years, with 100 dogs successfully vaccinated. That makes it the largest vaccination ever of wild dogs. It also means every pack of wild dogs in the Kruger National Park is collared for the first time in the park’s history.
Notre Dame, Scoop Makhathini, GoT, top week in search
From fire disaster to social media disaster, the top Google searches this week covered a wide gamut of themes.
Paris and the whole world looked on in shock as the 856-year-old medieval Catholic cathedral crumbled into ash. The tragic infernal destruction of this tourist attraction of historical and religious significance led South Africans to generate more than 200 000 search queries for “Notre Dame Cathedral” on Monday. Authorities are investigating the cause of the fire that razed the architectural icon.
In other top trending searches on Google this week, radio presenter Siyabonga Ngwekazi, AKA Scoop Makhathini, went viral when it appeared he had taken to Twitter to expose his girlfriend, Akhona Carpede, for cheating on him. Scoop has since come out to say that he was not responsible for the bitter rant and that his account was hacked. “Scoop Makhathini” generated more than 20 000 search queries on Wednesday.
Fans generated more than 20 000 search queries for “Sam Smith” on Tuesday ahead of the the British superstar’s Cape Town performance at the Grand West Casino. Smith ended up cutting his performance short that night due to vocal strain.
Local Game of Thrones superfans were beside themselves on Sunday, searching the internet high and low for the first episode of the American fantasy drama’s eighth season. “Game of Thrones, season 8, episode 1” generated more than 100 000 queries on Google Search on the weekend.
As the festivities kicked off in California with headliners such as Childish Gambino and Ariana Grande, South Africans generated more than 2 000 search queries for “Coachella” on Saturday.
South Africans generated more than 5 000 search queries for “Wendy Williams” on Friday as it emerged that the American talk show host had filed for divorce from her husband Kevin Hunter after 21 years of marriage. Hunter has long been rumored to have been cheating on Williams, which reportedly finally led to the divorce.
Search trends information is gleaned from data collated by Google based on what South Africans have been searching for and asking Google. Google processes more than 40 000 search queries every second. This translates to more than a billion searches per day and 1.2 trillion searches per year worldwide.

5G smartphones to hit 5M sales in 2019
According to the latest research from Strategy Analytics, global smartphone shipments will reach a modest 5 million units in 2019. Early 5G smartphone models will be expensive and available in limited volumes. Samsung, LG and Huawei will be the early 5G smartphone leaders this year, followed by Apple next year.
Ken Hyers, Director at Strategy Analytics, said, “We forecast global 5G smartphone shipments will reach a modest 5 million units in 2019. Less than 1 percent of all smartphones shipped worldwide will be 5G-enabled this year. Global 5G smartphone shipments are tiny for now, due to expensive device pricing, component bottlenecks, and restricted availability of active 5G networks.”
Ville Petteri-Ukonaho, senior analyst at Strategy Analytics, added, “Samsung will be the early 5G smartphone leader in the first half of 2019, due to initial launches across South Korea and the United States. We predict LG, Huawei, Xiaomi, Motorola and others will follow later in the year, followed by Apple iPhone with its first 5G model during the second half of 2020. The iPhone looks set to be at least a year behind Samsung in the 5G smartphone race and Apple must be careful not to fall too far behind.”
Neil Mawston, executive director at Strategy Analytics, added, “The short-term outlook for 5G smartphones is weak, but the long-term opportunity remains huge. We forecast 1 billion 5G smartphones to ship worldwide per year by 2025. The introduction of 5G networks, by carriers like Verizon or China Mobile, opens up high-speed, ultra-low-latency services such as 8K video, streaming games, and augmented reality for business. The next big question for the mobile industry is how much extra consumers are really willing to pay, if anything, for those emerging 5G smartphones and services.”
