	The Republic of Equatorial Guinea is located in west central Africa. The country comprises Bioko Island, Annobón Island, and the larger mainland region of Rio Muni, which lies between Cameroon and Gabon and includes the nearby islands of Corisco, Elobey Grande, Elobey Chico, and adjacent islets. Rio Muni covers an area of 26,017 sq. km. The vegetation consists mainly of Guineo-Congolian rainforest, with mangrove forests in the southwest estuary, riparian palm forests along the coast and inselbergs in the east (Murai et al. 2013). The highest altitude reaches 1,113 m in the Niefang Mountain range. Average annual temperature is around 27°C and annual mean rainfall is 2,500 mm (Murai et al. 2013).

	The first gorilla survey, conducted in 1966, provided a nationwide density estimate of 0.58 to 0.86 gorilla per sq. km (Murai et al. 2013). Later on, in 1989, surve work led to an estimate of 0.22 to 0.45 nesting gorilla per sq. km, with the highest densities identified to be in Río Campo and the district of Nsork in the southeast of the country (Murai et al. 2013).

	The nationwide population size estimate of apes in 2011 stands at 11,097, with a maximum population of 7,824 chimpanzees and a minimum population of 3,273 gorillas (Murai et al. 2013). Great apes were most abundant within Monte Alén National Park and the region extending south towards Gabon, which is part of the Monte Alén-Monts de Cristal transboundary landscape (Murai et al. 2013). The Río Campo Nature Reserve is also an important area, as well as the region to the east of the reserve (Murai et al. 2013).

	Fuelled by the country's oil boom, Equatorial Guinea's economy has rapidly developed. Forest concessions have grown significantly since the discovery of oil reserves in the early 1990s; in fact, between 1993 and 1997 concessions more than doubled to 1.5 million hectares (Murai et al 2013). The area further increased to 1.7 million hectares by 2001. This economic development has also led to greater urbanisation and increased infrastructure development and road construction throughout Río Muni (Murai et al. 2013).

	A 2011 nationwide survey revealed that proximity to cities and settlements were important determining factors for chimpanzee abundance in Equatorial Guinea (Murai et al. 2013). Increasing distance to cities and settlements led to increases in chimpanzee abundance. The presence of roads was also identified as a determining factor of gorilla and chimpanzee abundance (Murai et al. 2013). Human population density is high almost throughout the country; not even the most remote areas are further than ~15 km from a road. The effects of high human population density and proximity to roads are aggravated by the lack of patrols in the country's PAs (Strindberg et al. 2018). Roads have made access to the forest easier for hunters. Hunting has also been exacerbated by the ease in the firearm ban in 1979, making both guns and cartridges more affordable and accessible (Murai et al. 2013). Extensive commercial bushmeat hunting in the country and the presence of large urban bushmeat markets in Río Muni are well known (Murai et al. 2013).

	Two priority landscapes for great ape conservation have been identified, which cover parts of Rio Muni. First, the Monte Alén-Monts de Cristal-Abanga landscape, which incorporates the Monts de Cristal mountain chain running from northwest Equatorial Guinea to southeast Gabon. The Equatorial Guinea sector covers 5,570 sq. km (IUCN 2014). The second is the Río-Campo-Ma’an landscape, which comprises the Río Campo Natural Reserve (347 km²) in Equatorial Guinea and Campo Ma’an NP (CMNP, 2,640 km²) in Cameroon. The landscape falls in the Atlantic coastal forest zone, known for high floral diversity and several endemic plant species (IUCN 2014).

	Historically, the network of PAs has existed in Equatorial Guinea by law since 1988 (Ley 8/1988). Today, PAs in Río Muni cover 15.4% of the country’s land. However, since 2004 there are limited law enforcement activities undertaken to manage and protect these areas, when ECOFAC (Conservation et Utilisation Rationelle des Ecosystèmes Forestieres en Afrique Centrale) suspended its activities in Monte Alén National Park (Murai et al. 2013). This park is the only PA that has received any effective protection since the creation of the PA network in Rio Muni (Murai et al 2013). This lack of law enforcement is threatening wildlife populations (Murai et al. 2013).		Historically, the network of PAs has existed in Equatorial Guinea by law since 1988 (Ley 8/1988).

The first gorilla survey, conducted in 1966, provided a nationwide density estimate of 0.58 to 0.86 gorilla per sq. km (Murai et al. 2013). Later on, in 1989, surve work led to an estimate of 0.22 to 0.45 nesting gorilla per sq. km, with the highest densities identified to be in Río Campo and the district of Nsork in the southeast of the country (Murai et al. 2013).

The nationwide population size estimate of apes in 2011 stands at 11,097, with a maximum population of 7,824 chimpanzees and a minimum population of 3,273 gorillas (Murai et al. 2013). Great apes were most abundant within Monte Alén National Park and the region extending south towards Gabon, which is part of the Monte Alén-Monts de Cristal transboundary landscape (Murai et al. 2013). The Río Campo Nature Reserve is also an important area, as well as the region to the east of the reserve (Murai et al. 2013).

Fuelled by the country's oil boom, Equatorial Guinea's economy has rapidly developed. Forest concessions have grown significantly since the discovery of oil reserves in the early 1990s; in fact, between 1993 and 1997 concessions more than doubled to 1.5 million hectares (Murai et al 2013). The area further increased to 1.7 million hectares by 2001. This economic development has also led to greater urbanisation and increased infrastructure development and road construction throughout Río Muni (Murai et al. 2013).

A 2011 nationwide survey revealed that proximity to cities and settlements were important determining factors for chimpanzee abundance in Equatorial Guinea (Murai et al. 2013). Increasing distance to cities and settlements led to increases in chimpanzee abundance. The presence of roads was also identified as a determining factor of gorilla and chimpanzee abundance (Murai et al. 2013). Human population density is high almost throughout the country; not even the most remote areas are further than ~15 km from a road. The effects of high human population density and proximity to roads are aggravated by the lack of patrols in the country's PAs (Strindberg et al. 2018). Roads have made access to the forest easier for hunters. Hunting has also been exacerbated by the ease in the firearm ban in 1979, making both guns and cartridges more affordable and accessible (Murai et al. 2013). Extensive commercial bushmeat hunting in the country and the presence of large urban bushmeat markets in Río Muni are well known (Murai et al. 2013).

First, the Monte Alén-Monts de Cristal-Abanga landscape, which incorporates the Monts de Cristal mountain chain running from northwest Equatorial Guinea to southeast Gabon. The Equatorial Guinea sector covers 5,570 sq. km (IUCN 2014). The second is the Río-Campo-Ma’an landscape, which comprises the Río Campo Natural Reserve (347 km²) in Equatorial Guinea and Campo Ma’an NP (CMNP, 2,640 km²) in Cameroon. The landscape falls in the Atlantic coastal forest zone, known for high floral diversity and several endemic plant species (IUCN 2014).

However, since 2004 there are limited law enforcement activities undertaken to manage and protect these areas, when ECOFAC (Conservation et Utilisation Rationelle des Ecosystèmes Forestieres en Afrique Centrale) suspended its activities in Monte Alén National Park (Murai et al. 2013). This park is the only PA that has received any effective protection since the creation of the PA network in Rio Muni (Murai et al 2013). This lack of law enforcement is threatening wildlife populations (Murai et al. 2013).
