Ecosystem and Relict Cultural Landscape of Lopé-Okanda: A Unique Interface Between Nature and Culture
The Ecosystem and Relict Cultural Landscape of Lopé-Okanda, inscribed as a UNESCO World Heritage Site in 2007, offers a captivating blend of natural beauty and cultural heritage. Situated in central Gabon, this unique property spans an area of approximately 4,912 square miles (1,897 square kilometers), bordered by the Ogooué River to the north and the Chaillu Massif to the south.
More to come…UNESCO Description of the World Heritage Site
The Ecosystem and Relict Cultural Landscape of Lopé-Okanda demonstrates an unusual interface between dense and well-conserved tropical rainforest and relict savannah environments with a great diversity of species, including endangered large mammals, and habitats. The site illustrates ecological and biological processes in terms of species and habitat adaptation to post-glacial climatic changes. It contains evidence of the successive passages of different peoples who have left extensive and comparatively well-preserved remains of habitation around hilltops, caves and shelters, evidence of iron-working and a remarkable collection of some 1,800 petroglyphs (rock carvings). The property’s collection of Neolithic and Iron Age sites, together with the rock art found there, reflects a major migration route of Bantu and other peoples from West Africa along the River Ogooué valley to the north of the dense evergreen Congo forests and to central east and southern Africa, that has shaped the development of the whole of sub-Saharan Africa.
UNESCO Justification of the World Heritage Site
Criterion (iii): the rich archaeological ensembles of the middle stretches of the River Ogooué Valley demonstrate 400,000 years of almost continuous history. The archaeological sites have revealed the earliest date for the extension of Tshitolien culture towards the Atlantic, as well as detailed evidence for the early use of forest produce, cultivation of crops and the domestication of animals.
Criterion (iv): the collection of Neolithic and Iron Age sites together with the rock art remains appear to reflect a major migration route of Bantu and other peoples along the River Ogooué valley to the north of the dense evergreen Congo forests from West Africa to central east and southern Africa, that has shaped the development of the whole of sub-Saharan Africa. The subsidiary Iron Age sites within the forest provide evidence for the development of forest communities and their relationship with present day peoples.
Criterion (ix): The nominated property demonstrates an unusual interface between forest and savannah environments, and a very important manifestation of evolutionary processes in terms of species and habitat adaptation to post-glacial climatic changes. The diversity of species and habitats present are the result of natural processes and also the long-term interaction between man and nature.
Criterion (x): The diversity of habitats and the complex relationship between forest and savannah ecosystems have contributed to a high biological diversity particularly in relation to the property's flora, making it one of the most outstanding areas in relation to floristic diversity and complexity in the Congo Rainforest Biogeographical Province. Over 1,550 plant species have been recorded, including 40 never recorded before in Gabon, and it is anticipated that once all the floristic surveys and research are completed the number of plant species could reach over 3,000.

History, Development, and Politics of Protected Areas in the Congo Basin Countries
Protected areas in the Congo Basin, including UNESCO World Heritage Sites like Lopé-Okanda, have been critical biodiversity refuges despite historical abuses tied to colonial-era resource management. While pre-colonial conservation practices such as taboos and seasonal hunting restrictions existed, modern protected areas emerged under centralized models that often violated human rights but preserved biodiversity amid rising demographic pressures. Recent shifts toward IUCN Category VI reserves and community-led conservation models aim to balance biodiversity protection with human development needs, addressing past injustices while safeguarding the region's ecological integrity.

Genomic Signatures of Microgeographic Adaptation in Anopheles coluzzii Across Urban, Rural, and Forested Environments in Gabon
A study on Anopheles coluzzii, a major malaria mosquito in Gabon, reveals rapid microgeographic adaptation in populations despite ongoing gene flow. Using whole genome re-sequencing of 96 mosquitoes, researchers identified strong selective pressures in urban areas, likely due to insecticides or pollution, while proximate rural and forested populations showed distinctive soft-selective sweeps on standing genetic variation. Demographic analyses suggest a ∼12,000-year-old divergence between urban Libreville and La Lopé National Park populations, followed by asymmetric gene flow around 4,000 years ago. The findings highlight how local adaptation persists in heterogeneous environments, advancing understanding of malaria mosquito evolution.

Contribution of small rodent communities (Muridae) to the history of West Central African savannas (case of Gabonese savannas): diversity, biogeographic affinities, phylogeography and paleoenvironmental analyses
A new study reveals that the fragmentation of small rodent populations in Gabonese savannas occurred over 50,000 years ago, supporting the hypothesis that these savannas originated from paleoclimatic fluctuations rather than solely anthropogenic factors. The research compared phylogeographic patterns of strictly savanicolous rodents using mitochondrial DNA and nested clade analysis, aligning with paleobiological data on tropical West African vegetation changes. This findings challenge the classical anthropic hypothesis, suggesting a complex history of savanna expansion and fragmentation in West Central Africa.

The Rise and Fall of Protected Areas in Central Africa
Modern proposals for protected areas (PAs) in Central Africa often echo colonial-era practices, perpetuating historical injustices while aiming to meet global biodiversity targets. This study reveals that territorialization—a strategic control of bounded space—links colonial reserves like the Mont Fouari hunting complex and Yangambi Floristic Reserve to contemporary PAs such as Lomami National Park. While newer proposals incorporate community consultation, they still risk resurrecting colonial legacies, raising concerns about equity and biodiversity outcomes. The research traces these connections through historical analysis, highlighting the enduring consequences of territorialization on local communities and ecosystems.

Invasion of forested areas in Gabon (Central Africa) by the Asian tiger mosquito and the potential consequences from the One Health perspective
Aedes albopictus, the invasive Asian tiger mosquito, has extended its range into remote forested areas of Gabon, including the Lopé-Okanda UNESCO World Heritage Site, raising concerns about zoonotic pathogen transmission. Research from 2014 to 2018 revealed that while Ae. albopictus is significantly more abundant near human settlements, it also colonizes forest galleries up to 15 km away, particularly at anthropized-sylvatic interfaces. Egg deposition decreased with distance from the forest fringe, suggesting its role as a bridge vector between wild and anthropogenic environments. The study used ovitraps, larval surveys, BG-Sentinel traps, and human landing catches along an anthropization gradient to assess colonization patterns, highlighting potential spillover risks for dengue, chikungunya, and Zika under a One Health framework.
