Conservation Careers

In Mozambique’s Niassa Special Reserve, Dr Samuell Bilerio, a wildlife veterinarian and passionate advocate for human-wildlife coexistence, is making a profound impact.

His approach to conservation goes beyond veterinary care; it integrates community involvement, innovative solutions, and long-term planning. His career highlights the crucial role that veterinary medicine plays in broader conservation efforts, particularly in addressing the challenges posed by wildlife conservation in Africa.

Samuell’s story is not just about his work with animals; it’s a testament to the integration of science, community engagement, and hands-on conservation. Here’s a deeper look at his journey, his work and the lessons he’s learned along the way.

A personal journey sparked by curiosity and passion

Samuell’s passion for wildlife and conservation began in his early years when he was greatly influenced by National Geographic documentaries which sparked his curiosity about the natural world. “I was fascinated by the resilience of wildlife and the challenges they faced due to human activities,” he recalls, and this led him to pursue veterinary medicine.

He soon realised the immense potential veterinarians have not only in treating animals, but also in addressing conservation, environmental and public health challenges, particularly those arising from Human Wildlife Conflict (HWC).

Through his early field experiences, especially in the Niassa Special Reserve, Samuell recognised the interdependence of wildlife, domestic animals and human health. This realisation led him to adopt the One Health approach, which focuses on addressing wildlife health alongside broader environmental and human health challenges.

A defining career moment

A pivotal moment in Samuell’s early career occurred while he was working in the Niassa Special Reserve, and had to respond to a lion caught in a snare, suffering severe injuries. This wasn’t just any ordinary case. The snare had been set not to target lions, but to catch bushmeat for subsistence. Samuell, alongside the response team, treated and released the lion, but this experience stuck with him.

“It made me realise that conservation isn’t just about protecting wildlife, it’s about understanding the socio-economic realities that drive human behaviour,” he explains.

He also reflects on a powerful quote from Nelson Mandela: “Conservation is about people.” This moment, seeing how conservation overlaps with human survival, reinforced Samuell’s commitment to community-based conservation and the need for solutions that bridge human-wildlife conflict and local development.

The ‘One Health Approach’

A core principle of Samuell’s work is the One Health Approach – a concept that emphasises the interconnectedness of human, animal and environmental health. Samuell has integrated this framework into his daily conservation work, ensuring that veterinary practices support broader conservation goals while addressing human health concerns.

This is especially important in areas where wildlife diseases like rabies can affect both animals and humans. By applying a holistic approach, Samuell and his team are addressing not just the immediate health of wildlife but also the long-term sustainability of ecosystems and human populations.

Balancing clinical work with conservation efforts

As a wildlife veterinarian, Samuell’s work goes beyond treating individual animals. His role is a combination of field research, disease surveillance, community engagement and policy advocacy.

“Balancing clinical responsibilities with on-the-ground conservation efforts requires a multidisciplinary approach,” he explains. “It’s not just about treating animals; it’s about finding solutions that consider the ecological, community, and health aspects together.”

A typical day for Samuell is never the same. He could start his day conducting health checks on wildlife, such as collaring lions for research or treating injured elephants. By midday, he might be visiting villages affected by human-wildlife conflict, offering training and implementing safety measures.

His afternoons often involve analysing field data, reporting, and preparing proposals. “At times, I work as a field operative during the day and a strategist by night, problem-solving and managing multiple responsibilities,” he adds.

The challenges and rewards of working in the field

Working in Mozambique’s Niassa Special Reserve has brought Samuell face-to-face with some of the toughest conservation challenges, but also some of the most rewarding experiences. One such instance occurred when a lion repeatedly attacked a community, forcing Samuell and his team to respond swiftly to ensure the safety of the people. Samuell’s team spent three days in the bush, capturing the lion and safely relocating it to a protected area away from human settlements.

“This experience reinforced the idea that conservation is about finding solutions that balance community safety with wildlife protection,” Samuell reflects. “Rather than taking a life, the focus was on removing the threat and ensuring the lion could continue to play its role in the ecosystem, safely away from human conflict. The reward came not just from protecting the community, but from showing that conservation can involve solutions where both people and wildlife benefit.”

In addition to the logistical challenges of working in remote areas with unpredictable weather and limited resources, he emphasises the importance of building trust within communities. “You need to show the community that they are part of the solution,” he says. The key is aligning conservation goals with local needs, which is vital for fostering long-term, sustainable change.

Addressing human-wildlife conflict and anti-poaching efforts

Human-wildlife conflict remains one of the most significant challenges in conservation. Samuell’s approach focuses on engaging communities and using non-lethal deterrents like chili fences to protect crops from elephants, beekeeping to deter lions and predator-proof enclosures for livestock. These methods help reduce tensions while providing alternative livelihoods to lessen the pressure on wildlife.

For anti-poaching, Samuell has supported rapid response teams and collaborated with law enforcement to tackle wildlife crime. He also uses SMART technology (Spatial Monitoring and Reporting Tool, a technology used by wildlife conservationists and law enforcement), which helps park rangers track animal movements and poaching activity in real time, making patrols more efficient.

Essential skills for aspiring wildlife veterinarians

So, what does it take to become a wildlife vet like Samuell? It’s all about balancing technical know-how and people skills. On the technical side, you need a solid foundation in wildlife health, disease management, field vet practices and ecological knowledge.

But don’t forget the soft skills! You’ve got to be a pro at community engagement, problem-solving, adaptability, and teamwork.

Samuell’s advice for young conservationists? “Be prepared, stay calm, and build trust with local communities.” It’s not just about the science – it’s about understanding local cultures, learning the language and working side-by-side with communities. After all, conservation is a team sport, and the more you connect with the people around you, the bigger the impact you can make.

Staying current with best practices and emerging technologies

To stay at the forefront of wildlife conservation, Samuell actively engages with networks and conservation organisations like the Wildlife Conservation Society (WCS) and the International Union for Conservation of Nature (IUCN).

In Mozambique, he is closely involved with organizations like the Mozambique Wildlife Alliance (MWA) and the Niassa Carnivore Project. “These organisations offer invaluable resources, from workshops and webinars to field training and networking opportunities,” he says.

The role of collaboration and partnerships

Samuell’s work is a prime example of the power of collaboration. Whether it’s partnering with local communities, government agencies, or other NGOs, Samuell understands that conservation success relies on strong partnerships.

He strongly recommends that aspiring conservationists get involved through internships, volunteering and networking with a range of related organisations, saying “Collaboration is key to understanding the diverse needs of conservation and working toward lasting solutions.”
