The present contribution is the product of palm research on continental African taxa started 7 years ago and represents an update to our taxonomic floristic knowledge. Current estimates indicate that this flora represented by 68 species, grouped in 18 genera attributed three subfamilies (Calamoideae, Coryphoideaea Arecoideae). Although much less species rich when compared with other floras, palms are extremely interesting from different perspectives, including phylogenetics, economic botany,...
Objectifs: Inventorier et évaluer le niveau de connaissance d’exploitation des plantes sauvages comestibles dans Département Bondoukou au Nord-Est la Côte d’Ivoire.Méthodologie Résultats: Des groupes discussion (focus group) entretiens structurés ont été employés pour recueillir les informations auprès 4 peuples autochtones 7 villages. Les espèces récoltées puis déterminées à l’herbier du CSRS. Au total 81 appartenant 76 genres 41 familles sont consommées. Malvaceae, Annonaceae, Arecaceae...
Pterocarpus erinaceus Poir (Fabaceae) is a sudanese multipurpose species ranging in Côte d'Ivoire, at the north of 8 th parallel. This object illegal exploitation and survival its natural populations strongly threatened. The sustainable management this resource requires an improvement germinative capacities. To achieve goal, five pretreatments were applied to seeds collected from population “Réserve du Haut Bandama”. These treatments include flowing water soaking during three days or 72...
Objectif : Cette étude réalisée à Agbaou, a visé l'identification et l'évaluation de la disponibilité des espèces végétales usages traditionnels localité.Méthodologie résultats La récolte données consisté réaliser relevés floristiques 200 m2 dans plantations, jachères, fragments forêts appartenant une réserve botanique en création ainsi que espaces paysans environnants. Des populations locales ont été aussi interviewées sur l'utilisation végétales. Les complétées travers littérature. A...
Lectotypification of Raphia sudanica A. Chev. (Arecaceae, Calamoideae), with notes on its biology and conservation.During a botanical survey undertaken in Western Africa 1905, Auguste Chevalier (1873–1956) collected new palm species that he described published 1908 under the name Two specimens are cited protologue, but herbarium where they were deposited was not indicated. Research Muséum national d'Histoire naturelle, Paris (P), France enabled us to locate two specimens. Neither them...
Eremospatha dransfieldii is a robust rattan palm, climbing up to 40 m in length. It only known occur the south-western region of Ghana, south-eastern part Côte d'Ivoire and Sierra Leone. The species' Area Occupancy (AOO) restricted just km². This species confined moist-evergreen forests with high rainfall. be facing habitat loss over-harvesting its stems. We assess as Endangered based on criteron B2ab(iii), according IUCN Red List Categories Criteria (ver 3.1).
L’étude a été réalisée dans trois îlots de forêts naturelles caractérisées par différents modes gestion les zones sèches Côte d’Ivoire. Son objectif est d’évaluer la composition et diversité floristique ces reliques forestières afin promouvoir le meilleur mode pour conservation forêts. L’échantillonnage végétation conduit forestiers Lataha, Dolékaha Korhogo. La collecte des données à l’aide méthode relevé surface complétée inventaires itinérants. Tous individus diamètre hauteur poitrine...
Dans le Département de Bondoukou (Nord-Est, Côte d’Ivoire), il existe une chaîne hauts plateaux, connue sous nom « monts Bowé Kiendi », dont la flore est très peu connue. L’objectif l’étude d’évaluer diversité et structure cette zone, suivant gradient altitudinal. Pour ce faire des inventaires ont été réalisés dans parcelles 625 m2 installées à différentes altitudes. chaque parcelle, les paramètres dendrométriques (diamètre, hauteur) mesurés. La richesse floristique indices biocénotique...
The contribution of dryland forests in West Africa to carbon stocks remains poorly documented due the lack appropriate allometric models and inventory data. In this study, we gathered such data for forest relics northern Côte d'Ivoire. Inventory were used determine sample dominant species, characterize stand structure. Destructive biomass develop local mixed-species estimating tree aboveground (AGB) test validity existing models, structure (including stock). A total 118 species belonging 102...
Landfills are contaminated sites that need to be cleaned up prevent human and environmental exposure pollutants. This article aims identify local plants capable of restoring soil polluted by heavy metals. To this end, plant species at the Bonoua landfill were inventoried. X-ray fluorescence spectrometry was used determine metal content from landfill. The bioconcentration factor (BCF) metals in evaluated. is covered with 62 species, comprising 28 botanical families 50 genera. BCF varied 0.08...
La présente étude se propose d'analyser la composition et diversité floristique des îles du barrage de Buyo après forte anthropisation.À l'aide relevé surface, linéaire itinérant, onze ont été déterminées.L'inventaire a permis noter 723 espèces plantes reparties entre 353 genres 99 familles.L'importance écologique appréciée à partir l'Indice Valeur d'Importance.L'étude montré que pour les arbres diamètre ≥ 10 cm, Alchornea cordifolia, Ceiba pentandra, Theobroma cacao, Lannea welwitschii sont...
The Tanoe-Ehy Forest, located in the South-Eastern of Côte d’Ivoire is one rare forest cover this type that still exists Country. These Forest was identified as a top priority site for conservation West Africa. However, important subject to strong anthropogenic pressures which through poaching, uncontrolled takeoffs natural resources and some agricultural clearing. A Botanical study based on plots, itinerant linear inventory conducted intends assess plant species diversity value biodiversity...
Background: Weeds are always seen as pests and continuously destroyed by farmers due to their impacts on crop production. But like many other plants, some have several virtues. This work aims determine the uses of weed plants cashew in three 4 regions Côte d'Ivoire.Methods: In each region, an ethnobotanical survey using semi-direct interviews with 108 producers let identify weeds orchards used highlight uses.Results: total, 73 were cited useful for various uses, thus justifying maintenance...
Botanical gardens represent important places for ex situ conservation. One of these botanical has been abandoned in Côte d’Ivoire 30 years. This is the former garden ORSTOM. study was conducted to determine level diversity this order assess opportunity its rehabilitation. The authors carried out inventories 18 quadrats 500 m2 through vegetation collect woody species. Dendrometric measurements (height, diameter) were also recorded structure site. A total 190 species have identified. They...
La présente étude a été réalisée dans les forêts classées de Kimbrila et Kanhasso au Nord-Ouest la Côte d’Ivoire. Dans le cadre cette étude, il s’agit d’établir une connaissance flore structure végétation partie du septentrion Pour ce faire, des inventaires surface itinérants ont réalisés à travers deux formations végétales. richesse, diversité l’équitabilité ligneux évaluées. par ailleurs étudiée densité ligneux, terrière, diamétrique verticale. Les résultats établissent un total 127 104...
We report for the first time occurence of Hyphaene guineensis Schumach. & Thonn. (Arecaceae) in flora Benin at Grand-Popo. describe this species using stem, leaf, and fruit morphological traits from field observations, specialized keys, historical modern herbarium vouchers. Demographic phenological observations are also provided, a key is proposed differentiating H. other known Benin. This work contributes to knowledge geographical distribution, ecology, conservation tropical Africa.
