In this study we provide the first comprehensive camera-trap assessment of terrestrial mammals in the Yangambi landscape, comprising the Yangambi Biosphere Reserve and a logging concession in the Democratic Republic of the Congo. The terrestrial mammal community in this area exhibits lower occupancy and species richness compared to other conservation areas in the Congo Basin. The community is dominated by four species: Emin's pouched rat Cricetomys emini (1.3 kg), African brush-tailed porcupine Atherurus africanus (2.8 kg), blue duiker Philantomba monticola (5 kg) and bay duiker Cephalophus dorsalis (12 kg), which are known to be highly resilient. Large ungulates and medium-sized carnivores have particularly low abundances. Our study also confirmed the presence of four species categorized as threatened on the IUCN Red List: the chimpanzee Pan troglodytes , giant ground pangolin Smutsia gigantea , black-bellied pangolin Phataginus tetradactyla and white-bellied pangolin Phataginus tricuspis. Our findings highlight the need to consider wildlife conservation at the landscape level, including the logging concession, where species showed higher occupancy levels compared to the Biosphere Reserve, and highlighting the need for planning infrastructure construction and developing mitigation schemes, reducing forest degradation from logging and developing permanent cash crop agriculture. Landscape-level conservation will only be possible if a collaborative management model steered by local communities is developed with the participation of all constituencies. [ABSTRACT FROM AUTHOR]

Baseline population data are fundamental to the development of wildlife management plans and are usually generated based on field surveys using sampling tools such as camera traps (CT). However, this method can be costly and ineffective with rare species or in wildlife-depleted areas. An alternative is to complement baseline wildlife population data with Local Ecological Knowledge (LEK)-based methods. We compared LEK and CT surveys in terms of their capacity to assess the status of terrestrial mammal species (richness, abundance, distribution) in the Yangambi landscape of the Democratic Republic of Congo. This region is heavily hunted and wildlife population densities are low. Species not captured by CT included naturally rare and endangered species that were instead recorded by interviewed hunters. LEK and CT abundance metrics were positively related for all species. For all medium- and largesized species, the number of positive sites from LEK outnumbered the number of positive sites from the CT survey, indicating that hunters detected species over larger areas. Overall, our comparison suggests that LEK and CT methods can be used interchangeably to provide reliable information on relative abundance. Nevertheless, LEK appears as a more cost-effective alternative to camera trapping, particularly for hunted and depleted tropical forests. [ABSTRACT FROM AUTHOR]

The rise of zoonotic disease-related public health crises has sparked calls for policy action, including calls to close wildlife markets. Yet, these calls often reflect limited understanding of where, precisely, exposure to risk occurs along wildlife and wild meat trade chains. They also threaten to negatively impact food security and livelihoods. From a public health perspective, it is important to understand the practices that shape food safety all along the trade chain, resulting in meat that is either safe to eat or managed as a potential vector of pathogens. This article uses ethnographic methods to examine the steps that lead a wild animal from the forest to the plate of an urban consumer in Yangambi and Kisangani in the Democratic Republic of Congo (DRC). Focusing on hunters, village-level consumers, transporters, market traders and urban consumers, we highlight specific practices that expose different actors involved in the trade chain to wild meat related health risks, including exposure to food borne illnesses from contaminated meat and zoonotic pathogens through direct contact with wild animals, and the local practices in place to reduce the same. We discuss interventions that could help prevent and mitigate zoonotic and food borne disease risks associated with wild meat trade chains. [ABSTRACT FROM AUTHOR]
