​The Rangers of Gorongosa National Park, Mozambique

Approximately 260 trained rangers are employed by Gorongosa National Park to protect the environment from threats such as illegal logging and wildlife trade. Those of us that conduct research in Mozambique as part of the Paleo-Primate Project Gorongosa are greatly supported by these rangers. For safety reasons, all researchers working in the Park must be accompanied by a ranger when on foot in the field, and since we spend a great deal of our time in the field on foot (be this following primates, excavating fossils sites, conducting surveys, or otherwise), our research would simply not be possible without them. Many of the rangers are from the local area and are hugely knowledgeable about the Park and its wildlife, the environments in which we work, and provide valuable insight about how to navigate conducting fieldwork within the at times challenging landscape. They often share valuable knowledge and insights about the site’s flora and fauna, for example assisting in identifying tree species during surveys and sharing what local communities may use them for. In 2018, a documentary film highlighting the Gorongosa Rangers was released: Na Linha da Frente: Os Fiscais do Parque Nacional da Gorongosa (On the Front Line: The Rangers of Gorongosa National Park). You can read more about the important work of the rangers and watch a trailer for the documentary here. We are inspired by their hard work and dedication to protecting Gorongosa and its people, and their knowledge of the Park and its wildlife which is instrumental to our research. We are in the process of creating individual profiles for the rangers that we have worked with most frequently in Gorongosa National Park and look forward to sharing more of these below soon.

​Gonçalves Verinca

Verinca has been a ranger at Gorongosa National Park since 1995. He is passionate about the conservation of biodiversity and finds the most challenging aspect of monitoring such biodiversity to be coming to terms with the reality that there are others that want to destroy it. Thanks to the efforts of Verinca and his fellow rangers, the number of individuals of various species in Gorongosa National Park has increased – their work is essential to the conservation of the ecosystem. Verinca has worked with a number of our Lab members helping them to habituate and study baboon and vervet monkey troops in Gorongosa, as well as assisting with the paleontological side of research at the excavation sites. He enjoys this work as he believes it will allow a new generation to learn more about the animals that existed far back in time and hopes the findings can be used to create an education centre to allow people to see these fossils for themselves. Verinca is originally from the town of Inhaminga in Cheringoma district, but now lives in Dondo district. His principal language is Sena. Verinca’s family is very proud of his profession as a ranger.

​Daniel Maveneco Mamenhane

Maveneco has been a ranger in Gorongosa National Park since 2005 and says his favourite part of his profession is accompanying scientists, tourists, and colleagues in the field. The most difficult part is walking in the bush with the challenge of dangerous animals. With his experience, Maveneco has learnt much about the wildlife of the local area and the rules pertaining to forests – knowledge which we are very appreciative of when we carry out research in the Park. In turn, Mavenco tells us he enjoys assisting and learning with us about areas of research he wasn’t previously aware of. Maveneco is originally from Gaza Province and the district of Manjacaza, but now lives in Metuchira in Nhamatanda district. His main language is Changana.
