This article aims to examine how Matacong Island, a small island just off the coast of the Republic of Guinea, West Africa, was claimed its possession by local chiefs, how it was leased to and was used by European and Sierra Leonean merchants, and how it was colonized by Britain and France in the 19th century. In 1825 the paramount chief of Moriah chiefdom agreed to lease the island to two Sierra Leonean merchants, and in 1826 it was ceded to Britain by a treaty with chiefs of the Sumbuyah and Moriah chiefdoms. Since the island was considered as a territory exempted from duty, British and Sierra Leonean merchants used it as an important trading station throughout the 19th century. Major exports of Matacong Island included palm kernels, palm oil, hides, ivory, pepper and groundnuts, originally brought by local traders from the neighboring rivers, and major imports were tobacco, beads, guns, gunpowder, rum, cotton manufactures, iron bars and hardware of various kinds. In 1853 alone, some 80 vessels, under British, American, and French flags, anchored at Matacong Island. By the convention of 1882, Britain recognized the island as belonging to France. Although the convention was never ratified, it was treated by both countries as accepted terms of agreement. The article considers various dynamics of usage, property, and territorial possession as relates to the island during the 19th century, and reveals how complex they were, widely making use of the documents of The Matacong Island (West Africa) Papers at the University of Birmingham Library in Britain. The collection purchased by the library in 1969 is composed of 265 historical documents relating to Matacong Island, such as letters, agreements, newspaper-cuttings, maps and water-color picture

AbstractThe Republic of Guinea has one of the highest diversities of mammal species in West Africa. However, its protected area network is poorly developed and little quantitative information has been available to help guide national conservation strategies. I therefore examined the distribution of antelopes and related species (families Bovidae and Tragulidae) across 17 sites, including four protected areas, to determine how the existing protected area network contributes to the conservation of antelope species and where action should best be focused for the conservation of this group. A total of 21 species of antelope have been recorded in the 17 sites; four of these species are absent from the four protected areas. An iterative heuristic complementarity approach was used to determine an irreplaceability index, which accounts for both species richness and species rarity, for each of the sites. The Kankan Faunal Reserve and Nimba Strict Nature Reserve have the second and fourth highest irreplaceability indices, respectively. The two other protected areas have moderate to very low irreplaceability indices, showing that they protect species widespread throughout the 17 sites. The Ziama Forest has the highest index (because it contains a high number of species and of globally threatened species), highlighting the significance of this site. I discuss the importance of the other sites and the threats affecting antelopes in Guinea, and make recommendations to improve the study and conservation of antelope species in the country.

This paper presents the results of a mammal survey conducted between 1995 and 1997 in the newly established National Park of Upper Niger in the Republic of Guinea, West Africa. Ninety-four species of mammals were recorded in the park area and its environs; 19 of these species were newly recorded or confirmed for Guinea. The fauna of the park includes about 50% of the known mammalian diversity of the country. Among the species found are West African endemics such as the Gambian mongoose Mungos gambianus. The park, although situated in the Guinea savannah belt, includes some remnant forest, which harbours tropical forest mammals such as Thomas's galago Galagoides cf. thomasi, hump-nosed mouse Hybomys planifrons, soft-furred rat Praomys rostratus and flying squirrel Anomalurops sp.. This National Park is a high priority area for the conservation of the vertebrate diversity of West Africa.
