Using Cyber Tracking Technology to Outsmart Poachers

ImageJef Dupain

I’m just recently back in Lomie (on border of the Dja Faunal Reserve in Cameroon) from two days of practical training for rangers on the use of the CyberTracker/Trimble for ecological monitoring and anti-poaching.

Instead of counting living monkeys, elephants, and great apes, we witnessed the arrest of about 15 poachers on more than five different occasions. We have been hiding and running, sleeping on the ground next to the fire with guards at both sides of our overnight spot— switching every two hours, assuring security. The Conservator, Achile Mengamenya, who was with us, has a good and dedicated team of park wardens (we were about 20). Nobody complains, while equipment is lacking, and everybody works hard. We were fed water and some rice and tomato sauce in the evening, and in the morning we have one or two beignets for each.

The total amount of confiscated illegal wildlife, from the poachers, is surprising—sitatunga, forest duikers, living and dead pangolin, several species of monkey, freshly killed or smoked. No chimp, gorilla or elephant meat though…as these species are victim of a different type and more specialized category of hunters.

We heard only one group of chimps was heard about 1 km from our campsite, so we can consider that this periphery of this Natural World Heritage site is probably almost hunted out.

However, based on the interrogations of the arrested poachers, and witnesses of some park guards, it is clear that the Dja is still housing good numbers of all species, and remains attractive for a lot of people who prefer to put snares in the park instead of working on their fields in the village. With the Dja managers lacking any support for the last few years, and no control happening anymore, the Dja Biosphere is being hit very hard. And poachers are getting increasingly aggressive. Over the last few weeks, one guard got shot in his arm, another received a blow of a machete above his eye, and last night inhabitants of Lomie attacked the post of the Conservator and his team.

Alain Lushimba (who is here with me, taking the lead in the training on cybertracker) and myself agree on the area’s high resemblance with the Lomako Yokokala Faunal Reserve. While being a beautiful forest with high potentials for biodiversity, the Dja is probably in the same conditions today as the Lomako forest was in 2004 when AWF started working in DRC. Support is needed. “Performance Based Management” and “Evidence-based Conservation” à la Lomako, and the lessons learned, will prove most helpful here. The park authorities and their team are extremely happy with the support we are giving.

Today, we will adapt a work plan in order to respond, first of all, to the absolute priority to get those poachers out of the Reserve, restore law and order, and let the people know that the conservator and his team are operational again.

All paths will be georeferenced, poaching camps destroyed, traces of gorillas, chimps, elephants, bongo and buffaloes recorded, and groups of monkeys—now all frightened—counted. Data will be shared with AWF headquarters the AWF-GIS (mapping) Centre. Evaluation on the ground is planned about 4 to 5months from now.

The CyberTracker Story

The Origin of Science

CyberTracker has grown from a simple hypothesis: The art of tracking may have been the origin of science. Science may have evolved more than a hundred thousand years ago with the evolution of modern hunter-gatherers. Scientific reasoning may therefore be an innate ability of the human mind. This may have far-reaching implications for indigenous knowledge, citizen science and self-education.

The Persistence Hunt

In 1990 I ran the persistence hunt with !Nate at Lone Tree in the Kalahari. The persistence hunt involves running down an antelope in the mid-day heat on an extremely hot day – chasing the antelope until it drops from heat exhaustion. This may well be one of the oldest forms of hunting, going back two million years ago, long before humans invented bows and arrows. Persistence hunting may have played a critical role in the evolution of the art of tracking and the origin of science.

In 2001 I worked with David Attenborough on the BBC film showing Karoha doing the Persistence Hunt. You can watch Karoha running down a kudu in the video at

Reviving the Dying Art of Tracking

After running the persistence hunt in 1990 !Nate asked me to help them. They could no longer live as hunter-gathers and needed jobs. Wildlife in the Kalahari has been decimated by fences that cut off migration routes. It was no longer viable to live as hunter-gatherers. And the art of tracking was dying out. After hundreds of thousands of years, traditional tracking skills may soon be lost. Yet tracking can be developed into a new science with far-reaching implications for nature conservation.

We had lengthy discussions around the fire, and it was decided that I should try to find a way to create jobs for trackers. Only by developing tracking into a modern profession, will tracking itself survive into the future. !Nam!kabe agreed that this will be good for the future. But he also had the wisdom to know that it will take a long time. This was for the younger generation, he said, it will not be for him. When he died in 1995 his exceptional tracking expertise was irretrievably lost. He was one of the last of the old generation hunters and one of the best trackers. !Nam!kabe inspired the creation of the Master Tracker certificate – the highest standard of tracking that others could aspire to.

The Tracker Evaluation methodology that I developed provide certification of practical tracking skills, thereby enabling trackers to get jobs in ecotourism, as rangers in anti-poaching units, in wildlife monitoring and scientific research. Tracker evaluations have since 1994 resulted in a steady growth of trackers with increasing levels of tracking skills, thereby reviving tracking as a modern profession.

The Tracker Institute was established as a centre of learning for the highest standards of excellence in the art of tracking and to develop the next generation of Master Trackers. The Tracker Institute is situated in the Thornybush Nature Reserve, providing the opportunity to track lion, leopard, rhino and a wide diversity of species. In addition to providing intensive individual mentoring of practical tracking skills, it will also serve as a research institute.

CyberTracker

If the art of tracking was the origin of science, then modern-day trackers should be able to do science. However, some of the best traditional trackers in Africa cannot read or write. To overcome this problem, the CyberTracker software was developed with an icon-based user interface that enabled expert non-literate trackers to record complex geo-referenced observations on animal behaviour.

In 1996 I teamed up with Justin Steventon, a brilliant young computer science student at the University of Cape Town. The CyberTracker user interface was developed with the help of Karel Benadie, a tracker working in the Karoo National Park in South Africa. Together with fellow ranger and tracker James Minye, they tracked the highly endangered Black Rhino, recording their movements and behaviour in minute detail. Together we published a paper on rhino feeding behaviour in the journal Pachyderm. This is perhaps the first paper based on data gathered independently by two non-literate trackers, confirming a hypothesis about rhino feeding behaviour put forward by the trackers. It was a demonstration that non-literate trackers can do science.

In 2008 the Western Kgalagadi Conservation Corridor Project was initiated, funded by Conservation International for a three-year period. Community members from several villages were employed to use the CyberTracker to conduct track counts. This was the first time that !Nate and Karoha were employed in a major research project, enabling them to use their traditional tracking skills, using the CyberTracker, in a modern context.

Involving scientists and local communities in key areas of biodiversity, CyberTracker combines indigenous knowledge with state-of-the-art computer and satellite technology.

Towards a New Tracking Science

From its origins with the Kalahari San trackers, CyberTracker projects have been initiated to monitor gorillas in the Congo, butterflies in Switzerland, the Sumatran rhino in Borneo, jaguars in Costa Rica, birds in the Amazon, wild horses in Mongolia, dolphins in California, marine turtles in the Pacific and whales in Antarctica.

CyberTracker is being used by indigenous communities, in national parks, scientific research, citizen science, environmental education, forestry, farming, social surveys, health surveys, crime prevention and disaster relief.

The CyberTracker story is captured in the powerful image of Karoha holding the CyberTracker, with his hunting bag slung over his shoulder. The image symbolises the cultural transition from hunter-gatherer to the modern computer age. Persistence hunting may be the most ancient form of hunting, possibly going back two million years, long before the invention of the bow-and-arrow or the domestication of dogs. After two million years, Karoha may well be the last hunter who has been doing the persistence hunt. Yet of all the hunters at Kagcae, Karoha is the most proficient in using the CyberTracker. In Karoha, one individual not only represents one of the most ancient human traditions, but also the future of tracking with computers.

Karoha’s story represents the most profound cultural leap – a story that gives hope for the future: The ancient art of tracking can be revitalized and developed into a new science to monitor the impact of climate change on biodiversity.

At a more fundamental level, it shows us that anyone, regardless of their level of education, whether or not they can read or write, regardless of their cultural background, can make a contribution to science.
