Composition Floristique, Diversité Et Structure Des Espèces Forestières Alimentaires De La Région De Sikasso Au Sud Du Mali

Abstract

The present work was launched to assess the floristic composition and structure of the native forest food species in order to tackle malnutrition. It was carried out in four natural forest from villages in two agro-ecological zones (two villages per agro-ecological zone) in southern Mali. In each natural forest, data were collected in 10 plots of 50 x 50 m using sampling systematic to one degree. In each plot, all tree were measured. Dendrometric data were collected on each tree (diameter at breast height or d.b.h and total stem height). In each plot, the total number of seedlings (diameter at breast height < 3 cm) was carried out within five 25 m² plots using sampling systematic to two degrees. The inventories were recorded 89 native forest species belonging to 73 genera and 30 botanical families. Native edible species were represented 34.83% of the overall inventoried species. Significant differences were observed between natural forest for average density per hectare, average height and average basal area. The high density was observed in Badogo (71 trees.ha -1 ), while the less in Sorobasso (24 trees.ha -1 ) which present the high regeneration rate (2.88%). The analysis of population diameter structures for Saba senegalensis, Vitellaria paradoxa, Lannea acida, Lannea microcarpa, Lophira lanceolata, Parkia biglobosa and Borassus aethiopum showed variable trends. Domestication and vegetative propagation strategies of the species are needed to ensure the availability of the resource to combat malnutrition.

“…Madjimbé et al (2019) revealed in their research in the same area that the most important families are Fabaceae and Combretaceae. Regarding the highest number of genera per family and the most abundant species, these results corroborate the results of Saradoum (2012), Ndotam et al (2017) and Kouyate et al (2020). The latter, in their study found that species of the family Combretaceae, Poaceae, Fabaceae, Rubiacea and Apocynaceae were the most numerous and the most abundant species are Prosopis africana, Detarium microcarpum, Flueggea virosa, Piliostigma reticulatum and Anogeissus leiocarpa.…”

“…The larger the trees in a vegetation types, the less dense they are. Human pressure in woodland and tree savanna could be explained by the low presence of reproductive individuals due to abusive exploitation, especially of woody forest products (Kouyate et al, 2020). These results are confirmed by Diouf et al (2019) who indicate that the low basal area is explained by the presence of a strong community of small diameter reflecting a stand with shrub dominance.…”

“…These results are confirmed by Kouyate et al (2020) in the woody formations of Sikasso, in southern Mali, with shannon diversity index of 4.99 and that of Giliba et al (2011) in the Miombo forest in Tanzania with Shannon diversity index of 4.27. The increasing demand for firewood and charcoal has not prevented the woody formation to be diversified.…”

“…and 10.41% (in Kodialan co-occurring with Isoberlinia doka, Lannea acida, and Terminalia sp.) (Kouyaté et al 2020). This shows that the increasing frequency of the three main companion species Bombax costatum, Piliostigma thonningii, and Terminalia macroptera decreases regeneration of D. microcarpum.…”
