Population structure of the widespread species, Anogeissus leiocarpa (DC.) Guill. & Perr. across the climatic gradient in West Africa semi-arid area
AbstractIn the climate change context, widely distributed plant species can serve as relevant barometers of ecosystems' sensitivity or resilience to disturbances. This study aimed at assessing the population structure and individual morphological traits of Anogeissus leiocarpa, a widespread tree species, across a broad strip of land, from the north to the south of Burkina Faso. We compared stands in four phytogeographical zones in order to analyze morphological variations in trees and recruits density, individual size and their spatial structure. Our results showed significant increase of tree density from the Sahel (77.1 trees/ha) to the South-Sudanian (166 trees/ha) while diameter, height and basal area had an opposite trend. No recruits were found in the Sahel stands, while their density increased from the Sub-Sahel (5.17 individuals/ha) to the South-Sudanian (6.46 individuals/ha). Tree diameters revealed positive asymmetric distributions in the Sudanian and Sub-Sahel whereas the Sahel stands showed a symmetric distribution. Height structure of saplings revealed âJ reverseâ shape in Sudanian stands while Sub-Sahelian ones exhibited Gaussian shape. Heightâdiameter relationships revealed thin trees towards the south-Sudanian. The spatial structure of trees indicated random distributions in all zones whereas recruits presented aggregative distribution trend in the Sudanian zones. A. leiocarpa's trees have a good ability to support broad climatic fluctuations but the populations' rejuvenation is unpredictable in the extreme harsh conditions. The species is fairly resilient to anthropogenic disturbances in Sub-Sahel and Sudanian zones. However, managing issues should pay attention to the species communities by considering its demographic behavior in the health state appreciation of ecosystems
Potentials for Promoting Oil Products Identified from Traditional Knowledge of Native Trees in Burkina Faso
Oil products from native trees are far from fully exploited in West Africa. Only well-known species like shea (Vitellaria paradoxa C.F. Gaertn.) and oil palm (Elaeis guineensis Jacq.) receive attention. We used quantitative questionnaires in 12 villages in Western Burkina Faso to assess the knowledge of four ethnic groups on 28 tree species and how their oil is used. Sixteen species were used the most. Among them, V. paradoxa, E. guineensis, Carapa procera DC., Pentadesma butyracea Sabine and Lophira lanceolata Tiegh. ex Keay received the most citations. Oils were used for soap (22%), food (21%), medicine (19%), body care (18%) and hair care (14%). Significant differences were found among ethnic groups concerning knowledge and preferences of oil products. Apart from the well-known species, C. procera, L. lanceolata and P. butyracea appear to be promising species for promotable oil products and a number of less known species may show potentials as well.
Potentialités agroforestiÚres de Maranthes polyandra (Benth.) Prance au sud-ouest du Burkina Faso
Objectif: Le maintien dâarbres et dâarbustes dans les champs, en association avec les cultures est certes liĂ© Ă leur utilitĂ© alimentaire, mĂ©dicinale, mais aussi Ă leurs aptitudes Ă amĂ©liorer la fertilitĂ© des sols. Des observations ont rĂ©vĂ©lĂ© une flore ligneuse abondante qui pousse prĂ©fĂ©rentiellement au pied de Maranthes polyandra (Benth.) Prance. Elles ont suscitĂ© lâhypothĂšse que M. polyandra a des propriĂ©tĂ©s agro-Ă©cologiques intĂ©ressantes. Lâobjectif de lâĂ©tude est dâĂ©valuer les relations entre M. polyandra et les propriĂ©tĂ©s physiques et chimiques du sol.MĂ©thodes et rĂ©sultats: La quantitĂ© de litiĂšre foliaire sous le houppier de M. polyandra a Ă©tĂ© collectĂ©e et pesĂ©e. Des Ă©chantillons de sol ont Ă©tĂ© prĂ©levĂ©s sous le houppier et hors du houppier de M. polyandra pour des analyses physico-chimiques. Les mĂȘmes travaux ont Ă©tĂ© rĂ©alisĂ©s Ă titre comparatif avec Vitellaria paradoxa C.F.Gaertn., qui est une espĂšce agroforestiĂšre connue.La quantitĂ© moyenne de litiĂšre foliaire sous M. polyandra est de 28,82 ± 16,08 kg par individu contre 5,92 ± 3,07 kg pour V. paradoxa. Nous avons trouvĂ© des teneurs significativement plus Ă©levĂ©es en carbone total, en azote total, en phosphore total, en potassium total et en somme des bases Ă©changeables sous M. polyandra, comparativement Ă V. paradoxa. Les paramĂštres de texture sont significativement meilleurs pour le sol sous houppier de M. polyandra.Conclusion et application des rĂ©sultats: Ce travail Ă permis dâĂ©tudier les relations entre M. polyandra et les propriĂ©tĂ©s physiques et chimiques du sol. Il a montrĂ© que lâespĂšce a un potentiel Ă amĂ©liorer la fertilitĂ© physique et chimique du sol. Maranthes polyandra pourrait ĂȘtre adoptĂ©e comme espĂšce agroforestiĂšre pour amĂ©liorer la fertilitĂ© du sol. Au Burkina Faso, plus de la moitiĂ© des terres sont pauvres en matiĂšre organique, en phosphore et en azote. Ces niveaux bas constituent la contrainte majeure pour la production agricole. Ainsi, M. polyandra pourrait ĂȘtre adoptĂ©e comme espĂšce agroforestiĂšre pour amĂ©liorer la fertilitĂ© du sol en plus de son exploitation pour lâalimentation et comme bois dâĂ©nergie ; Cela pourrait constituer une raison supplĂ©mentaire pour sa conservation.Mots clĂ©s: Agroforesterie, Maranthes polyandra, FertilitĂ© du sol, Burkina Faso, Domestication, ConservationEnglish Title: Agroforestry potentials of Maranthes polyandra (Benth.) Prance in the south-west of Burkina FasoEnglish AbstractObjective: Maintaining trees and shrubs in fields in association with crops is linked to their use as food, firewood and pharmacopoeia, but also to their ability to improve physicochemical properties of soils. Observations revealed the presence of many plant species that grow preferentially at the foot of Maranthes polyandra (Benth.) Prance. These observations led to the hypothesis that M. polyandra has interesting agroecological properties. The objective of the study is to assess the relationship between M. polyandra and the physical and chemical properties of soil.Method and Results. The leaf litter under the crown of M. polyandra was collected and weighed. Soil samples were collected under the crown and outside the crown of M. polyandra for physicochemical analyses. The same work was carried out with Vitellaria paradoxa C.F. Gaertn. which is a known agroforestry species.The litter under M. polyandra is 28.82 ± 16.08 kg per individual plant compared to 5.92 ± 3.07 kg for V. paradoxa. Physicochemical analysis of the soil revealed, higher contents of organic carbon, total nitrogen, total phosphorus, total potassium and values in the sum of exchangeable bases under M. polyandra compared withthose obtained under V. paradoxa. These texture parameters are significantly better for the soil under crowns of M. polyandra.Conclusion and application of results: This work studied the relations between M. polyandra and the physical and chemical properties of the soil. It has shown that the species has potential to improve the physical and chemical fertility of the soil. Maranthes polyandra could be adopted as an agroforestry specie to improve soil fertility by its ability to enhance organic matter, phosphorus, nitrogen and potassium of the soils. In Burkina Faso, more than half of the land is poor in organic matter, in phosphorus and in nitrogen. This low levels are the major constraint for agricultural production. Thus, M. polyandra can be used to improve soils fertility in addition to its exploitation as food and firewood. This may be an additional reason for its conservation.Keywords: Agroforestry, Maranthes polyandra, Soil fertility, Burkina Faso,Domestication, Conservatio
Perceptions, mode de gestion et végétation des bois sacrés au nord du Burkina Faso
Im Rahmen der vorliegenden Studie wurden Flora und Vegetation der heiligen Haine im Norden Burkina Fasos erfasst. Ziele waren dabei eine Bewertung des Artenreichtums sowie die Erlangung von Kenntnissen zum Management natĂŒrlicher Ressourcen durch die lokale Bevölkerung und zur Bedeutung der heiligen Haine fĂŒr den Erhalt von BiodiversitĂ€t. An jedem Untersuchungsort wurde die direkt oder indirekt am traditionellen Management der heiligen Haine beteiligte Bevölkerung befragt. DarĂŒber hinaus wurden pflanzensoziologische Aufnahmen nach Braun-Blanquet durchgefĂŒhrt, wobei die AufnahmeflĂ€che bei der Gehölzvegetation jeweils 1000 qm, bei der krautigen Vegetation 100 qm betrug. 190 heilige Haine wurden gefunden, von denen 35 inklusive ihrer umgebenden Vegetation untersucht wurden. Die heiligen Haine und ihre Umgebung wurden schlieĂend bezĂŒglich ihres Arteninventars verglichen. Es zeigte sich, dass das Ressourcenmanagement in den heiligen Hainen auf traditionellen Regeln und Prinzipien beruht. Meist handelt es sich bei den heiligen Hainen um Friedhöfe (50 %), Fetische (17 %) oder Fetisch- und Friedhofsbereiche (27 %). FĂŒr die pflanzensoziologischen Untersuchungen standen 162 Aufnahmen zur VerfĂŒgung, die mit der CAP-Software (Community Analysis Package) bearbeitet wurden. Dabei wurden elf Pflanzengesellschaften identifiziert (fĂŒnf Gehölzgesellschaften und sechs Krautgesellschaften). Sieben dieser Pflanzengesellschaften wurden in den heiligen Hainen identifiziert und vier in deren Umgebung. Die floristische Analyse zeigt, dass in der Gehölzschicht die Leguminosae-Mimosoideae (16 %) und Combretaceae (12 %), in der Krautschicht die Poaceae (24 %) und Leguminosae-Papilionoideae (12 %) die wichtigsten Familien sind.This study lies within the scope of a valorization of sacred woodlands for better conservation of the biodiversity. The objective is to inventory the sacred woodlands in northern Burkina Faso, to evaluate their floristic richness and to learn about the management systems of natural resources by the local populations in order to understand their importance in the conservation of biodiversity. Preinvestigations were made in the whole study zone in order to inventory the sacred woodlands. In each locality the investigations were made of the populations directly or indirectly involved in the traditional management of these formations. Phytosociological relevĂ©s were carried out in the different phytocenoses according to the method of Braun-Blanquet (1932) in the area of 1000 m2 (woody) and 100 m2 (herbaceous) to define the plants communities. 190 sacred woodlands were listed of which 35 were the subject of botanical inventory. 35 surrounding formations were also the subject of inventory and their floristic potentialities were compared. The results revealed that the systems of natural resource management in sacred woodland are based on rules and traditional principles. These sacred woodlands are mostly the cemeteries (50% of the total), fetishes (17%), fetishes together with cemeteries (27%). The phytosociological data processing was carried out on the basis of 162 relevĂ©s by the software CAP (Community Analysis Package), which allowes us to define 11 plants communities (five woody plant community and 6 herbaceous plants communities. The relevĂ©s of seven plant communities were done in the sacred woodland and 4 were done in their environs. The floristic analysis shows that the most important families in the sacred woodlands and their environs are Leguminosae-Mimosoideae (16%), Combretaceae (12%) for the woody stratum and the Poaceae (24%), Leguminosae-Papilionoideae (12%) for the herbaceous stratum.LâĂ©tude sâinscrit dans le cadre de la valorisation des bois sacrĂ©s dans un contexte de conservation de la biodiversitĂ©, elle a pour objectifs de recenser les diffĂ©rents bois sacrĂ©s au nord du Burkina Faso, dâĂ©valuer leur richesse floristique et dâapprĂ©hender leurs mĂ©canismes de gestion par les populations locales.

The genus Borassus (Arecaceae) in West Africa, with a description of a new species from Burkina Faso
Borassus akeassii Bayton, Ouedraogo & Guinko sp. nov. (Arecaceae) is described as a new species from western Burkina Faso in West Africa. It has been confused with the widely distributed African species B. aethiopum and more recently with the Asian B. flabellifer. However, it is distinguished by its glaucous, green leaves with weakly armed petioles and a characteristic pattern of lamina venation. The fruits have a pointed apex and are greenish when ripe, and the flowers of the pistillate inflorescence are arranged in three spirals. The pollen has a reticulate tectum and distinctive ornamentation. The distribution of B. akeassii is discussed and the status of the varieties of Borassus aethiopum (var. bagamojensis and var. senegalensis) is examined. (c) 2006 The Linnean Society of London

Traditional plant use in Burkina Faso (West Africa): a national-scale analysis with focus on traditional medicine
BACKGROUND: The West African country of Burkina Faso (BFA) is an example for the enduring importance of traditional plant use today. A large proportion of its 17 million inhabitants lives in rural communities and strongly depends on local plant products for their livelihood. However, literature on traditional plant use is still scarce and a comprehensive analysis for the country is still missing.
METHODS: In this study we combine the information of a recently published plant checklist with information from ethnobotanical literature for a comprehensive, national scale analysis of plant use in Burkina Faso. We quantify the application of plant species in 10 different use categories, evaluate plant use on a plant family level and use the relative importance index to rank all species in the country according to their usefulness. We focus on traditional medicine and quantify the use of plants as remedy against 22 classes of health disorders, evaluate plant use in traditional medicine on the level of plant families and rank all species used in traditional medicine according to their respective usefulness.
RESULTS: A total of 1033 species (50%) in Burkina Faso had a documented use. Traditional medicine, human nutrition and animal fodder were the most important use categories. The 12 most common plant families in BFA differed considerably in their usefulness and application. Fabaceae, Poaceae and Malvaceae were the plant families with the most used species. In this study Khaya senegalensis, Adansonia digitata and Diospyros mespiliformis were ranked the top useful plants in BFA. Infections/Infestations, digestive system disorders and genitourinary disorders are the health problems most commonly addressed with medicinal plants. Fabaceae, Poaceae, Asteraceae, Apocynaceae, Malvaceae and Rubiaceae were the most important plant families in traditional medicine. Tamarindus indica, Vitellaria paradoxa and Adansonia digitata were ranked the most important medicinal plants.
CONCLUSIONS: The national-scale analysis revealed systematic patterns of traditional plant use throughout BFA. These results are of interest for applied research, as a detailed knowledge of traditional plant use can a) help to communicate conservation needs and b) facilitate future research on drug screening
Identification of driving factors of land degradation and deforestation in the Wildlife Reserve of Bontioli (Burkina Faso, West Africa)
In Africa, protected areas can play an important role in mitigating the effects of climate change through carbon sequestration but they are threatened due to increasing land degradation and deforestation (LDD). The Total Wildlife Reserve of Bontioli (TWRB) in Burkina Faso is one of the countryâs refuges with high biodiversity. This reserve is seriously threatened by human activities, and little information is available about the on-site causes of degradation extent. This study was carried out to investigate drivers and extent of LDD in the TWRB. Household surveys, focus group discussions and field observations were used to identify socio-economic factors that influence land use and land cover (LULC) changes. The socio-economic data were analyzed using rankings and binary logistic regression techniques. Logistic regression model was used to establish the relationship between socio-economic drivers and land cover change. Remote sensing and GIS techniques were used to analyze land use and LULC changes over 29 years, employing Landsat images of 1984, 2001 and 2013. We performed a supervised classification based on the maximum likelihood algorithm to derive vegetation maps. The results revealed significant (p <0.05) LULC change from one class of LULC to another. From 1984 to 2001, tree savannas, bare soils and agricultural lands increased by 17.55%, 18.79% and 21778.79%, respectively, while woodland, gallery forest, shrub savannas and water bodies decreased by 22.02%, 5.03%, 40.08% and 31.2%, respectively. From 2001 to 2013, gallery forests decreased by 14.33%, tree savannas by 22.30% and shrub savannas by 5.14%, while agricultural lands increased by 167.87% and woodlands by 3.21%. LDD occurred at a higher rate in areas bordering the reserve compared to the core-protected area and the inaccessible areas. Agricultural expansion and wood cutting activities were the main direct causes of LDD. Extensive land utilization for agriculture is a major threat to the conservation of biodiversity in this reserve. The research highlighted the soundness of GIS and remote sensing practical application to assess vegetation change extent in Burkina Faso. Understanding the signal extent of vegetation change is particularly important to support efforts by policy makers to halt or at least to slow down the deforestation in the country. There is a need to control the immediate causes of LULC dynamics by limiting agricultural land expansion and wood cutting in the study area
