Where the Dogs Lead
Tracking dogs and their Maasai handlers are helping to keep wildlife and people safe in northern Tanzania—and word of their effectiveness is spreading.
Olekashe, who previously served in the Tanzanian military, was recruited two years earlier by the African Wildlife Foundation (AWF) to help curb poaching in this important wildlife corridor that connects two of Tanzania’s most iconic national parks, Tarangire and Manyara. But as the phone call illustrated, poaching is not the only variety of crime Olekashe fights. And quite often he enlists the ranch’s highly trained tracker dog teams to help him in this work. At his request, two dogs and their handlers were already on their way, escorted by uniformed rangers.
When they arrive, Olekashe and the handlers, Kayongo Kalasinga and Saitabau Londasat, immediately begin inspecting the camp—initially without the dogs. Amidst a confusing mosaic of tracks, they identify two sets of fresh footprints off the main trail that lead, suspiciously, to the narrow space between the two looted tents. Kalasinga pulls on rubber gloves and uses stainless steel tongs to place pieces of clean gauze over the prints. “We leave the gauze on for five minutes to absorb the person’s smell,” he says. “Then the gauze is presented to the dog to track or match the scent to an actual person.”
After a few minutes, one of the handlers leads a striking maroon-red Alsatian named Rosdaz, its nose to the ground, to the area between the tents and from there, to an open-air kitchen. Here, the handler directs five camp staff members and about 10 others, including me, to stand still as he presents the dog with one of the pieces of gauze. After a few sniffs, Rosdaz matches the scent to one of the staff members; the dog stands up on his hind legs and places his front paws firmly against the man’s waist. The man, dressed in a crisp, collared shirt, stands motionless and stares straight ahead, avoiding the gaze of his accuser.
Because Rosdaz is still young, the handlers decide they want a second opinion. Rocky is a more classic looking Alsatian with a sloping back and dusty grey coat. At 7 years old, he’s more experienced and bolder than Rosdaz. As one of Tanzania’s two original tracker dogs, Rocky has already made a name for himself. He and another dog, now based in the Serengeti National Park, once tracked a poachers’ trail for some 7 hours. Ultimately, the dogs led rangers to a hidden stash of ivory weighing 60 kilograms (130 pounds), representing tusks from at least a half dozen elephants (Loxodonta africana
Eventually, the scent on the other piece of gauze leads Rocky to a second man in the circle. Both of these staff members had arrived just the night before with the camp manager to provide “expertise” to the local staff. And while the positive identification only connects the men to the suspicious tracks, not necessarily the crime, the evidence seems sufficient for the camp manager to initiate a line of questioning, and to consider reporting the men to local law enforcement authorities.
Tanzania, which recently boasted the continent’s second largest elephant population after Botswana, lost more than 60 percent of its elephants to poaching between 2009 and 2014. Seeking effective low-tech solutions to the problem, rangers began considering using dogs to track down poachers in the bush.
The use of highly trained dogs like Rocky and Rosdaz was pioneered by the Tanzanian conservation organization Honeyguide. (The organization is named after a group of birds in the Indicatoridae family that are known to lead people to sources of wild honey.) Honeyguide first established a conservation tracker dog unit in 2011 in West Kilimanjaro and was one of only a few such programs in Africa.
Poaching incidents in Manyara Ranch have fallen as well. In 2014 and 2015, poachers killed 17 elephants inside the ranch. This number fell to zero in 2016, although three elephants were speared on the outskirts of the ranch in retaliation for feeding on farmers’ crops. Thus far, 2017 has been quiet, with no elephants poached or speared. “These days, not only does an elephant die naturally, its tusks are left intact,” Olekashe says. “This would have never happened before.”
Rosdaz, elephant poaching at Manyara Ranch has been greatly reduced.
Keeping Dogs Alive and Well in the BushOn a stiflingly hot afternoon at Manyara Ranch, a young man stands just beyond the roof of a cavernous airplane hangar turning pieces of meat and bone drying in the sun. Flies drawn to the smell buzz around the rack, and curious superb starlings (Lamprotornis superbus) mill about looking for a free morsel. Once dried, the meat and bones will be ground and mixed in an enormous aluminum cooking pot with three other ingredients: sweet potatoes, lentils, and molasses. When complete, this particular batch of ingredients will yield about 75 kilograms (165 pounds) of dog biscuits, enough to feed Honeyguide’s four tracker dogs, Rocky, Rosdaz, Jerry, and Chester, for a little more than two weeks.
“Sometimes the meat comes from cows that have been predated on by large carnivores like lions,” says Ole Kirimbai, the Chairman of Honeyguide. “Our project buys what’s left of a cow or goat carcass as a way of helping reduce revenge killings of predators by villagers who’ve lost their livestock.” This transaction helps encourage conservation buy-in from local community members, who also rely on seasonal grazing rights on the ranch. Cattle, goats, and sheep move through the region with their Maasai herders.
“The dogs will follow you to where you live. Don’t even think about poaching there.”
To see this team in action, I board a small plane that will take me from Manyara Ranch to Serengeti National Park. Just moments after the plane lifts off above the narrow airstrip, the Rift Valley escarpment plunges beneath us. Its wall forms the eastern side of the sunken 14-mile-wide Ngorongoro Crater, which is home to all of Africa’s “Big 5” (elephant, rhino, buffalo, lion, and leopard). For the better part of two hours, the plane skims over seemingly endless yellow plains until finally we touch down in the middle of one of the richest ecosystems in Africa. Stepping off the plane, we’re met by Andrew Mbwambo, the park’s energetic veterinary technician.
“We work as a team,” Mbwambo says. “The handler will be the first to spot a problem and may need to administer emergency first aid. Detecting any sudden changes in behavior is vital: Did Chester eat or not eat his food today?”
To combat disease, each weekend, handlers wash their dogs in an anti-tick solution. They also maintain fine mesh on kennels and crates that house the dogs when they ride in the backs of vehicles to avoid exposure to tsetse flies. Mbwambo routinely administers sleeping sickness prophylaxis (an intervention originally developed for camels), which requires careful dosing. “Too much, and you’ll kill your dog,” he says. Too little, and the protection won’t work. Every month, blood samples are collected and checked for sleeping sickness antibodies. Purple-blue tsetse fly targets—steeped in insecticide—also hang near the dog kennels to kill the flies. Before going into the bush, handlers apply insect repellent to each dog, and they always carry plenty of water. After all, a panting dog can't pick up a scent.
“I was fond of dogs before becoming a handler,” Isaack says. “Training improved my commitment to them. People were more accustomed to using dogs for hunting. Now we’re using dogs to stop hunting.”
Isaack recounts tracking meat poachers back to their camps with dog Jerry. To avoid detection, these poachers tend to make camp far from where they dry the bushmeat—often small antelope such as impala or dikdik. “Once we ambushed a group while they were cooking their evening meal and were completely oblivious that they had been tracked from the site of their snares.”
Poaching of wild animals with snares remains one of the greatest conservation challenges in the Serengeti, and a Serengeti-wide de-snaring program is now in operation. Isaack shows me his collection of dozens of wire snares, which will be destroyed at the park’s headquarters. Unlike in Manyara Ranch, where snares aren’t set for fear of injuring cattle, the greater Serengeti ecosystem is dense with snares. Almost daily, the veterinary technician Mbwambo removes these traps from the legs, necks, and trunks of wild animals.
Emerging K-9 UnitsWhat began as a trial with just a few dogs less than a decade ago has become an essential tool in Africa’s conservation efforts. Honeyguide’s tracker dog teams alone have operated throughout northern Tanzania in nine national parks and community-based conservation areas. As word about the organization spread, Honeyguide established kennels in Manyara Ranch and partnered with Tanzania National Parks (TANAPA), the national parks authority, in the Serengeti. Since 2014, their efforts have helped lead to the arrests of more than 20 criminals and to seizures of illicit items including mining equipment, guns, and ammunition. In addition, they’ve collected and destroyed more than 400 snares and have confiscated bushmeat, ivory, and other wildlife products.
One recent convert to the conservation dogs model is the Singita Grumeti Fund and Ikorongo Game Reserve complex, a private concession that skirts the western edge of Serengeti National Park. Having called the Serengeti dog unit for assistance on several occasions, they’ve now decided to get dogs of their own. Four rescue dogs—two chocolate Labrador mixes and two Belgian Malinois—arrived in early September. They were trained in detection by Working Dogs for Conservation (WD4C), a Montana-based organization that sources its dogs from shelters.
“We wanted to complement the TANAPA facility, which is primarily a tracking program, by adding detection dogs to the ecosystem,” says Grant Burden, in charge of special projects at Grumeti. While Serengeti’s dogs will continue tracking, Grumeti’s dogs will detect wildlife contraband such as ivory, rhino horn, bush meat, ammunition, and pangolin scales. And soon, the dogs will be trained to detect wire snares and poisons as well.
As the number of tracking and detection dog programs continues to grow across Africa, a few key elements will be necessary to maximize the achievements of canine units: setting and maintaining standards and best practices, long-term donor support, and importantly, sharing knowledge and even resources.
“In conservation, we have limited resources,” says Damian Bell, Honeyguide’s executive director. “While dogs are expensive to maintain, they have proven effective at helping government and community ranger teams curb poaching and crime.” Bell estimates that it costs at least $30 thousand per year to maintain an established dog unit. The rationale is that if dogs are helping to keep the region’s protected areas, campsites, and communities safe, they are not only fostering positive attitudes toward conservation, but also helping secure a vital sector of Tanzania’s economy. Tourism is a mainstay in the country where the northern circuit—together with the islands of Zanzibar—generate some 90 percent of the country’s $1.3 billion in tourism earnings annually. These funds help subsidize Tanzania’s lesser-known and more remote national parks.
“We spread the word about the dogs through the people we train in crime-scene protection,” says Kirimbai, who was a member of Tanzania’s original anti-poaching unit established in 1978. “Sometimes this training—in how to leave a scene undisturbed so that the dogs can do their work—can be enough to deter illegal activities.” In other words, the people he trains become message multipliers. “There are no secrets in Tanzania,” he says.
Proof of this came during a recent bus ride, Kirimbai says. A head of anti-poaching efforts was coming for a meeting at Manyara Ranch and overheard another passenger say, in response to a comment about the area’s elephants and their valuable ivory, “The dogs will follow you to where you live. Don’t even think about poaching there.”
