Question: What reserve was established in 1991 to protect the habitat of the "Pan paniscus"?

full_context: Document 1: Mount Nimba Strict Nature Reserve: Mount Nimba Strict Nature Reserve is a protected area and UNESCO World Heritage Site located in both Guinea and Côte d'Ivoire, extending over a total of area of 17,540 hectares, with 12,540 hectares in Guinea, and 5,000 hectares in Côte d'Ivoire. The reserve covers significant portions of the Nimba Range, a geographically unique area with unusually rich flora and fauna, including exceptional numbers of single-site endemic species, such as viviparous toads, and horseshoe bats. Its highest peak is Mount Richard-Molard at 1,752 m (5,750 ft), which is the highest peak of both countries.
Document 2: Nomascus: Nomascus is the second-most speciose genus of gibbons (family Hylobatidae). Originally, this genus was a subgenus of "Hylobates", and all individuals were considered one species, "Hylobates concolor". Species within "Nomascus" are characterized by 52 chromosomes. Some species are all black, some are light with a distinct black tuft of crown fur, and some have distinct, light-colored cheek patches. "Nomascus" is found from southern China (Yunnan) to southern Vietnam, and also on Hainan Island. One species, "Nomascus nasutus," has been deemed "the most critically endangered ape species in the world". All species in this genus are endangered or critically endangered.
Document 3: Kogyae Strict Nature Reserve: Kogyae Strict Nature Reserve (or Kogyae) is a strict nature reserve, located near Kumasi, Ghana. The Kogyae Strict Nature Reserve was established in 1971 and has an area of 386 km. Animals present on the reserve include African buffalos, African civets, civet cats, and monkeys, as well as 85 species of birds. The reserve has taken the waterbuck as its symbol.
Document 4: Frances J. White: Frances Joy White is a biological anthropologist, professor, and primatologist at the University of Oregon. She has studied the socioecology of the bonobo chimpanzee ("Pan paniscus") for over 25 years at Lomako Forest in the Democratic Republic of Congo. She is the foremost American authority on this species in the wild and has done extensive field research on the bonobo or pygmy chimpanzees.
Document 5: List of Panamanian monkey species: At least six monkey species are native to Panama. A seventh species, the Coiba Island howler ("Alouatta coibensis") is often recognized, but some authors treat it as a subspecies of the mantled howler, ("A. palliata"). An eighth species, the black-headed spider monkey is also often recognized, but some authorities regard it as a subspecies of Geoffroy's spider monkey. All Panamanian monkey species are classified taxonomically as New World monkeys, and they belong to four families. The Coiba Island howler, mantled howler, black-headed spider monkey and Geoffroy's spider monkey all belong to the family Atelidae. The white-headed capuchin and Central American squirrel monkey belong to the family Cebidae. the family that includes the capuchin monkeys and squirrel monkeys. The Panamanian night monkey belongs to the family Aotidae, and Geoffroy's tamarin belongs to the family Callitrichidae.
Document 6: Réserve Naturelle Lomako Yokokala: The Lomako Forest Reserve is found in Democratic Republic of the Congo. It was established in 1991 especially to protect the habitat of the Bonobo apes. This site covers 3,601.88 km² 
Document 7: Bui National Park: The Bui National Park is found in Ghana. It was established in 1971. This site is 1820 km². The reserve is notable for its Hippopotamus population in the Black Volta. The endangered black and white colobus monkey and a variety of antelopes and birds are also present. Part of the park will be inundated by the reservoir of the Bui Dam, which has been under construction since 2009. The filling of the reservoir is expected to begin in 2011.
Document 8: Augustin Kambale: Augustin Kambale is the head of the Bukima ranger patrol post, in the Mikeno sector of Virunga National Park in the Democratic Republic of the Congo. His patrol group has gained notoriety in recent years due to the importance of Virunga to conservationists, as it serves as the refuge for 100 of the world's 700 remaining silverback gorillas. It has also been subjected to numerous bloody attacks from rebels camped or residing outside of the park boundaries; since 1996, over 120 Virunga rangers have been murdered by rebels such as the Mai Mai and the forces of General Laurent Nkunda. However, Nkunda signed a ceasefire in February 2007 with the government in Kinshasa, thus allowing for the rangers at Virunga to focus more on their jobs as conservationists.
Document 9: Ipassa Makokou Biosphere Reserve: The Ipassa Makokou Biosphere reserve is situated in Gabon and covers 150.00 km². Situated along the banks of the Ivindo River, Ipassa-Makokou Biosphere Reserve represents an example of the dense tropical rainforest of the Congo-Guinean phytogeographic region. The biosphere reserve is Gabon’s only area where no forest exploitation takes place thus the core area is in a relatively pristine state. Within the 15,000 hectares of the biosphere reserve, more than 2,000 plant species and 600 species of mammals, reptiles, fish, amphibians and birds have been recorded. Among the most threatened plant species are Ardisia belingensis and Rhaptopetalum belingensis.
Document 10: Bonobo: The bonobo ( or ; "Pan paniscus"), formerly called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus "Pan"; the other is "Pan troglodytes", or the common chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood as referring to the common chimpanzee, whereas "Pan paniscus" is usually referred to as the bonobo.
Document 11: Homininae: Homininae is a subfamily of Hominidae. It includes two tribes, with their extant as well as extinct species: the Hominini tribe (with the genus "Homo" including modern humans, Australopithecina, comprising at least three extinct (or, fossil) genera and the genus "Pan" including chimpanzees and bonobos), and the Gorillini tribe (gorillas). It comprises all hominids that arose after orangutans (subfamily Ponginae) split from the line of great apes. The Homininae cladogram has three main branches, which lead to gorillas (through the tribe Gorillini), and to humans and chimpanzees via the tribe Hominini and subtribes Hominina and Panina (see the evolutionary tree below). There are two living species of Panina (chimpanzees and bonobos) and two living species of gorillas, but only one extant human species. Traces of hypothetical "Homo" species, including "Homo floresiensis" and "Homo denisova", have been found with dates as recent as 40,000 years ago. Organisms in this class are described as hominine or hominines (not to be confused with the terms hominins or hominini).
Document 12: Isabel Behncke: Isabel Behncke Izquierdo is a Chilean primatologist who studies the social behaviour, especially play, of bonobos ("pan paniscus") the other species, together with Chimpanzee, inside the genus Pan. In 2011 she was a TED Fellow and gave a talk "Evolution's gift of play, from bonobo apes to humans".
Document 13: Gregoire (chimpanzee): Gregoire (c. 1942 – December 17, 2008) was, up until his death, Africa's oldest known chimpanzee. For the last eleven years of his life, he was a resident of the Tchimpounga Sanctuary (part of the Jane Goodall Institute) in the Republic of the Congo. He was observed to have a pair bond relationship with the chimpanzee Clara. Previously he had been confined by himself for more than 40 years in a cage at the Brazzaville Zoo before being rescued by staff of the Jane Goodall Institute and airlifted to the Sanctuary during a time of war.
Document 14: Dzanga-Sangha Special Reserve: The Dzanga-Sangha Special Reserve (also known as Dzanga-Sangha Forest Reserve, or Dzanga-Sangha Forest Special Reserve, Dzanga-Sangha Baï, or Dzanga-Sangha Special Forest Reserve) is a protected reserve of southwestern Central African Republic. It was established in 1990 and covers 6865.54 km. It is one of several areas within the Dzanga-Sangha Complex of Protected Areas (DSCPA), each within its own protective status and along with Lobéké National Park in Cameroon and Nouabalé-Ndoki National Park in Republic of Congo, it is part of the Sangha Trinational Landscape. Other areas within the DSCPA include the Dzanga Ndoki National Park which has two sectors, the 495 km Dzanga park and the 725 km Ndoki park. A conference of the Ministers of Forests of Central African Forest Commission (COMIFAC) had resolved to establish within the Congo basin, the Sangha River Tri-national Protected area (STN) encompassing these three parks. The forest special reserve is operated by the Central African Forest Commission (COMIFAC).
Document 15: Western Area Forest Reserve: Western Area Forest Reserve, also known as the Western Area Peninsula Forest Reserve, is a non-hunting forest reserve in Sierra Leone. The area became a forest reserve in 1916 and has an area of 17688 ha . It was demarcated by Charles Lane Poole, Sierra Leone's first ever 'Conservator of Forests,' and founder of the Sierra Leonean Forestry Department. It is the westernmost semi-deciduous closed canopy forest in Sierra Leone. The forest is home to various endangered species, including a wide variety of endangered birds and Duiker.
