Structure et dynamique de la flore et la végétation de la réserve spéciale botanique de Noflaye (Sénégal)

Abstract: La réserve spéciale botanique de Noflaye est un des rares écosystèmes particuliers de la zone des niayes de Dakar de par sa diversité floristique. Ce complexe est aujourd'hui menacé par un certain nombre de facteur tel que l'urbanisation. Cette étude a été réalisée pour caractériser la structure de la végétation du milieu. L'utilisation de la méthode des relevés dendrométriques nous a permis de caractériser la végétation du milieu. Les résultats indiquent que la richesse floristique du milieu est de 65 espèces… Show more

“…These results are consistent with those of [24] who conducted their study in the groundnut basin of Senegal, in the regions of Kaolack and Fatick. They are also in line with those of [25] who worked on the structure and dynamics of the flora and vegetation of the Noflaye Special Botanical Reserve.…”

“…The "inverted J" or "L" shape (Figure 5) was observed in the Tree Savanna and Shrub Savanna, characteristic of a type 1 stand, dominated by a large number of young individuals, a small number of large individuals with a regular reduction in the number of individuals from one size class to the next. This type of structure is characteristic of a stable stand with a strong presence of individuals in the young classes (Diouf et al, 2019). This indicates that large individuals are highly exploited as noted by Idrissa et al (2020).…”

“…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. Regarding the species with high basal area, these results of this article are similar to that of Wanie (2020) who found basal area dominance is due to individuals with developed trunks such as Anogeissus leiocarpa, Acacia polyacantha, Faidherbia albida, Tamarindus indica, and Balanites aegyptiaca and those of Baggnian et al (2019), the lowest basal area because the flora is dominated by species such as Guiera senegalensis and Hyphaene thebaica that are shrubs, with small trunks.…”

“…La méthode de relevé itinérant a été utilisée et consiste à parcourir la surface d'étude en notant toutes les espèces ligneuses rencontrées sur la fiche de relevé. Cette méthode a été adoptée de Ba et Noba (2001), Diouf et al (2019) et Sarr et al (2021. Une série de photos a été prise pour chaque espèce répertoriée et des échantillons fertiles ont été récoltés, mises sous presse de collectes puis ramener à l'Herbier Dakar.…”
