    Threatened plants species of Guinea-Conakry: A preliminary checklist Charlotte Couch1, Sékou Magassouba2, Saba Rokni1, Catia Canteiro1, Emma Williams1, Martin Cheek1 1 Identification and Naming, Royal Botanic Gardens Kew, Richmond, Surrey, UK. 2 Herbier National de Guinée, Conakry, Republic of Guinea Corresponding author: Charlotte Couch Email address: [email protected] PeerJ Preprints | https://doi.org/10.7287/peerj.preprints.3451v4 | CC BY 4.0 Open Access | rec: 17 Jul 2019, publ: 17 Jul 2019 Abstract Guinea-Conakry has one of the highest plant diversities in Sub-Saharan West Africa and is part of the Upper Guinean Forest ecoregion and the Guinean Forests of West Africa biodiversity hotspot. Guinea is a major supplier of the world’s bauxite and has significant reserves of high grade iron ore, it also has small reserves of diamonds, gold and uranium. As a result large areas of open cast mining exist in the country and pressure on habitats and vegetation are increasing with the need to bring revenue into the country; this is in addition to unsustainable slash and burn agriculture and a growing population. An initial list of 482 species was compiled from Lisowski’s Flore (Angiospermes) de la République de Guinée, subsequent discussion and screening reduced the list to 253. This list has since increased, through new species and range extensions, to 270 which is presented here. It is estimated that c. 7-8% of the countries flora is threatened. Rediscoveries and new species are being made in Guinea, but they are often already threatened having been discovered as part of Environmental Impact Assessments (EIAs).

  • Assessing Deforestation in the Guinea Highlands of West Africa Using
    Assessing Deforestation in the Guinea ~ighlandsof West Africa Using Remote Sensing I Peter T. Gilruth and Charles F. Hutchinson Arizona Remote Sensing Center, College of Agriculture, University of Arizona, Tucson, AZ 85721 Bademba Bury 1 National Direction of Forest and Game, Ministry of Agricultural and Animal Resources, Box 624, Conakry, Guinea ABSTRACT:Multiple remote sensing systems were used to assess deforestation in the Guinea Highlands (Fouta Djallon) of West Africa. Sensor systems included (1) historical (1953) and recent (1989) aerial mapping photography; (2) recent large-scale, small format (35-mm) aerial photography; (3) recent, large-scale aerial video imagery; and (4) historical (1973 and 1985) Landsat MSS imagery. Photographic and video data were manually interpreted and incorporated in a vector- based geographic information system (GIs). Landsat data were digitally classified. General results showed an increase in permanent (48 percent) and shifting (526 percent) agriculture over the past 35 years. This finding is consistent with hypothesized strategies to increase agricultural production through a shortening of the fallow period in areas of shifting cultivation. However, our remote sensing results also show that the total area of both permanent and shifting agriculture had expanded at the expense of natural vegetation along with an increase in eroded areas. Although sequential Landsat MSS imagery cannot be used in this region to map land cover accurately, the location, direction, and magnitude of changes can be detected in relative terms. Historical and current aerial photography can be used to map agricultural land-use change with better accuracy. Video imagery is useful as ancillary data for mapping vegetation.
