	The Dulombi National Park is located in southern Guinea-Bissau, bordering Guinea to the south. The park is part of a larger complex of protected areas, the Dulombi-Boé-Tchetche (DBT) Complex, formed by Dulombi National Park, Boé National Park, Tchetche wildlife corridor, Cuntabane-Quebo wildlife corridor and Salifo wildlife corridor. The park was established in 2017. The area is characterized by its great diversity of ecosystems, which are typical habitats of this transition zone between the Sudano-Sahelian and Guineo-Congolese regions. The Dulombi area is the area of greatest biodiversity in Guinea-Bissau due to the convergence of savannah and forest species, some endemic plants, with 164 species of birds, 10 species of primates, 13 carnivores and 17 ungulates, including many rare and endangered species, especially primates, such as the chimpanzee, ''Cercopithecus mona campbelli'', ''Papio papio'' and ''Erythrocebus patas''. The park contains some species characteristic of the savannah and the subtropical climate, such as aquatic species and some migratory species that use the various waterways. This area is also recognized as an International Bird Area (BirdLife International 2023).		The Dulombi National Park is located in southern Guinea-Bissau, bordering Guinea to the south.

= Site characteristics =

The Dulombi National Park is located in southern Guinea-Bissau, bordering Guinea to the south. The park is part of a larger complex of protected areas, the Dulombi-Boé-Tchetche (DBT) Complex, formed by Dulombi National Park, Boé National Park, Tchetche wildlife corridor, Cuntabane-Quebo wildlife corridor and Salifo wildlife corridor. The park was established in 2017. The area is characterized by its great diversity of ecosystems, which are typical habitats of this transition zone between the Sudano-Sahelian and Guineo-Congolese regions. The Dulombi area is the area of greatest biodiversity in Guinea-Bissau due to the convergence of savannah and forest species, some endemic plants, with 164 species of birds, 10 species of primates, 13 carnivores and 17 ungulates, including many rare and endangered species, especially primates, such as the chimpanzee, ''Cercopithecus mona campbelli'', ''Papio papio'' and ''Erythrocebus patas''. The park contains some species characteristic of the savannah and the subtropical climate, such as aquatic species and some migratory species that use the various waterways. This area is also recognized as an International Bird Area (BirdLife International 2023).

= Ape status =

Based on observations and data collected between 2011 and 2016 in the territories of Dijifilm and Paramanguel, which are part of Dulombi National Park, the average group size is about 7, but groups up to 19 animals have been observed. It is possible that at least 25 to 30 chimpanzees are present in the territories of Djifim and Paramanguel (Wit, P. & Goedmakers, A. 2022).

= Threats =

Although it is a protected area, the park model adopted by Guinea-Bissau contains human populations within it. This has the effect of increasing the pressure on wildlife. The chimpanzee is not hunted for meat consumption, however it faces several threats, including the destruction and fragmentation of its habitats by shifting agriculture and the plantation of cashew trees. Other threats are lower, but with negative impacts on the conservation of chimpanzee species, such as the installation of new villages, the use of biological resources, in particular fruit trees and timber, and other potential activities such as mining. But the population of chimpanzees in Dulombi has not been extensively studied, so there has not been an effective assessment or estimation of the level of impacts.

The Institute of Biodiversity and Protected Areas is the main structure in charge of the management of the park and the conservation of biodiversity. With the model of protected areas adopted with the communities inside, zoning is established, and 3 priority zones (integral conservation zone, buffer zone and development zone) have been defined for the use of space and resources are established in each area. This park was officially created in 2017, by Decree-Law, after years of negotiation with local communities. Since its creation, the park has been the subject of many management, conservation, awareness-raising and community development support actions with the support of the GEF project (2011-2017), GCCA+ (2014-2022).

[[Conservation activities]]
= Challenges =

The park has a Management Plan (2021) and a management structure, but the volatility and lack of sustainable funding hampers the implementation of conservation actions. There is also a lack of staff capacity on chimpanzee monitoring methods and capacity to cover the entire surface area of the protected area. Shifting cultivation followed by the planting of cashews is one of the greatest challenges facing this park. We need to invest even more in sustainable alternative activities.

Few research actions have been carried out in this recently created park. Camera-traps were installed (Bersacola, 2016) and also genetic studies (Silva Ferreira, 2016). Chimpanzee monitoring indicators have also been identified (IBAP, 2015) and complementary surveys of chimpanzee populations in the Cuntabane corridor (Biotope, 2020). In summary, little research has been conducted on this site.
