World Ranger Day: The Rangers Protecting Okonjima’s Rhinos and Pangolins
Before Sunrise: The Patrols That Protect Okonjima’s Wildlife
Before the first coffee is poured at Okonjima Nature Reserve, in the heart of the Namibian savannah, while the moon still hangs low and the cold winter air carries the last sounds of the night, the day’s most important work has already begun.
Across the reserve, members of the Anti-Poaching Unit (APU) have already spent hours in the field, locating every rhino, checking the perimeter fence and reporting back over the radio before the first light reaches the thornbush. Radios break the silence with quiet updates as patrol vehicles leave fresh tracks across familiar roads. Every observation is carefully recorded as the night’s surveillance gives way to the morning patrol. By the time guests leave the lodge for their morning game drive, the reserve has already been under the watchful eye of the APU for hours. Their work is matched after dark by researchers from the AfriCat Foundation, whose ecological monitoring programmes have tracked Okonjima’s wildlife for more than three decades. Most guests will never know either happened, and that is exactly the point.
“People often think our job is about responding to emergencies,” says Marcus Jacobs, Former Head of the Anti-Poaching Unit at Okonjima Nature Reserve. “In reality, the best days are the quiet ones. Every rhino has been found, every patrol has been completed, and everyone goes home safely. If that’s how the day ends, we’ve done our job.”
On 31 July, World Ranger Day marks its twentieth anniversary. Established by the International Ranger Federation in collaboration with The Thin Green Line, the day honours the men and women who protect the world’s natural and cultural heritage, while remembering the many rangers who have lost their lives or been injured in the line of duty. At Okonjima, it is an opportunity to recognise the people behind the quiet routines that protect wildlife every day of the year.
Rhino and Pangolin Protection at Okonjima Nature Reserve
The APU protects two very different species. The southern white rhinoceros (Ceratotherium simum simum) is one of Africa’s largest land mammals. An adult can weigh more than two tonnes and often feeds in open grasslands where it is easily seen by visitors. The Temminck’s ground pangolin (Smutsia temminckii), by contrast, is one of the continent’s most elusive mammals. Solitary and nocturnal, it spends much of its life hidden beneath the cover of darkness or inside burrows. Many people spend decades exploring Africa without ever seeing one in the wild.
Despite these differences, both animals face the same reality. Both are targeted by organised illegal wildlife trade. According to the International Union for Conservation of Nature (IUCN), the southern white rhinoceros is currently listed as Near Threatened, while the Temminck’s ground pangolin is listed as Vulnerable. Rhinos are targeted for their horns and pangolins for their scales, despite both being made primarily of keratin, the same protein found in human hair and fingernails. Their survival depends on effective legislation, scientific research and habitat protection, but on the ground, it depends on something much simpler: people being present every day.
Okonjima’s Anti-Poaching Unit: Born From a 2024 Loss
Though the APU is now part of the daily rhythm of the reserve, it is one of the newest initiatives created in response to one of the reserve’s most difficult moments. In 2024, a white rhinoceros was lost to poaching. The incident was a sobering reminder that even well-managed protected areas remain vulnerable to organised wildlife crime. For those responsible for the reserve’s wildlife, it was the loss of an individual animal that had been monitored, protected and known over several years. It also reinforced an important reality for conservation across Africa: as threats evolve, so too must the strategies used to counter them.
Rather than accepting the incident as an unavoidable calamity, Okonjima chose to strengthen its approach to wildlife protection. The reserve established a dedicated APU, to strengthen wildlife protection through proactive patrols, reserve security and continuous monitoring. Today, those patrols have become an essential part of daily life on the reserve. Their work is methodical and repetitive and exactly what effective conservation demands.
The Real Cost of Wildlife Protection at Okonjima
Patrolling a protected area is not simply a matter of putting boots on the ground. It requires trained personnel, specialised equipment, reliable vehicles, communication systems, infrastructure and ongoing operational support. These costs continue regardless of visitor numbers or external funding opportunities.
Former South African President Nelson Mandela once observed that “Ultimately conservation is about people. If you don’t have sustainable development around these parks, then the people will have no interest in them, and the parks will not survive.” His words remain just as relevant today. Long-term conservation depends not only on protecting wildlife, but also on creating sustainable models that enable people and nature to thrive together. Wayne Hanssen, owner of Okonjima Nature Reserve, shares that philosophy stating – “If we want to save a species, it must have value for people. When wildlife has value, people invest in protecting it.”
Across southern Africa, privately managed reserves demonstrate this principle every day. Conservation cannot rely solely on grants or emergency funding. It requires a model that generates the resources needed to protect wildlife continuously.
At Okonjima, tourism provides that foundation. Every occupied guest room helps support the Anti-Poaching Unit, long-term ecological research and the people working every day to safeguard the reserve’s wildlife across 22,000 hectares.
AfriCat Research Strengthens Anti-Poaching at Okonjima
Protecting wildlife requires more than vigilance alone. It also depends on understanding the animals being protected and the ecosystems they inhabit. For more than three decades, the AfriCat Foundation has conducted ecological research on Okonjima Nature Reserve, creating one of Namibia’s longest-running wildlife datasets. Research on carnivore ecology, animal movements, habitat use and biodiversity has informed reserve management, helping conservation decisions evolve alongside emerging challenges.
Today, that work is strengthened by technologies including GPS telemetry and the EarthRanger platform, which allow reserve managers to monitor wildlife movements, identify unusual patterns and coordinate field operations more effectively. While technology provides valuable information, it complements rather than replaces the experience of rangers on the ground. Rangers validate observations in the field, while their daily patrols generate information that contributes to long-term ecological research.
This partnership between research and field operations is particularly important for the Temminck’s ground pangolin. Unlike white rhino, pangolins are solitary, nocturnal and exceptionally elusive. Their secretive behaviour means that protecting them requires more than routine patrols. It demands an understanding of how they move through the landscape, which habitats they depend on and where the greatest risks occur.
Research at Okonjima extends beyond monitoring individual pangolins. Researchers are investigating the ecological processes that support their survival, including habitat use and the abundance and distribution of ants and termites, their primary prey. These findings help reserve management make informed decisions that benefit both the species and the ecosystems on which they depend. Together, research an protection form two sides of the same conservation strategy. One provides the knowledge, the other delivers the action.
Okonjima’s Anti-Poaching Unit Protects a Whole Ecosystem
Although the southern white rhino and the Temminck’s ground pangolin are the focus of the Anti-Poaching Unit, the team’s work extends far beyond these flagship species. Daily patrols contribute to the protection of an entire ecosystem. Fence inspections reduce opportunities for illegal entry, routine monitoring improves awareness across the Reserve and the constant presence of trained rangers helps safeguard the diverse wildlife that calls Okonjima home. This broader perspective reflects an important principle of modern conservation. Protecting threatened species is not simply about responding to immediate threats. It is about maintaining healthy ecosystems where wildlife can persist over the long term.
Conclusion
As the first light peaks over the Omboroko mountains each morning, the Anti-Poaching Unit will once again be in the field, carrying out the same quiet work that began long before sunrise. It is work few visitors will ever witness, yet it is fundamental to every wildlife sighting they enjoy.
World Ranger Day celebrates far more than a profession. It recognises the people working where conservation and society meet, often in a world where economic hardship, poverty and inequality place immense pressure on both people and natural resources, creating the conditions in which wildlife crime can take root. Meeting these challenges requires patience, professionalism and an understanding that lasting conservation depends on supporting both people and nature. At Okonjima, the Anti-Poaching Unit embodies that commitment, serving as guardians of a changing planet so that future generations may continue to experience thriving wildlife and healthy ecosystems.
Okonjima’s Anti-Poaching Unit (APU) protects the reserve’s rhino and pangolin populations through daily patrols, fence inspections and continuous monitoring. Patrols typically begin before dawn, locating every rhino on the reserve and checking the perimeter fence before guests leave for their first game drive of the day.
Drought is a temporary reduction in rainfall that dryland ecosystems are adapted to withstand. Desertification occurs when repeated pressures, including drought and unsustainable land use, reduce the land’s ability to recover after rainfall returns.
The AfriCat Foundation supports anti-poaching work at Okonjima through more than three decades of ecological research, including GPS telemetry, EarthRanger monitoring and habitat studies. This research helps reserve management understand animal movements and identify unusual patterns, complementing the physical presence of rangers on the ground.
Anti-poaching patrols at Okonjima take place before dawn and are not a guest activity in themselves. Most of this work happens out of sight by design, so that guests can experience undisturbed wildlife sightings during their stay.
