Impact de la structure spatiale de Strombosia scheffleri Engl. et Xymalos monospora (Harv.) Baill. sur la régénération naturelle et la coexistence des espèces arborescentes dans la réserve naturelle forestière de Bururi, Burundi

Abstract: Dans le but d'analyser l'influence de la structure spatiale sur le fonctionnement écologique des écosystèmes forestiers, une étude sur la distribution spatiale, la régénération naturelle et la coexistence des principales espèces arborescentes a été menée dans la réserve naturelle forestière de Bururi au Burundi. Cette aire protégée constitue la partie la plus méridionale du système de forêts de la crête Congo-Nil. La présente étude cherche à tester l'hypothèse selon laquelle la structure spatiale agrégée d'une… Show more

“…The average distance observed between trees is smaller at Affery (84.28 m) than at Biankouma (157.46 m). These results are similar to those obtained in Strombosia sheffleria [21]. The aggregate spatial distributions of some tree species can be interpreted as reflecting variations in environmental characteristics [22] [23].…”

“…Juxtaposition between patch types can also be considered as a component of landscape configuration. Patch dispersion assessment is often limited to the detection of aggregated, random or uniform patterns (Havyarimana et al 2013;Kumba et al 2013;Rakotondrasoa et al 2013).…”

“…The size of the plots was 2500 m 2 ; i.e. 50 m x 50 m. Many authors have used this plot size (0.25 ha) as observation units in the analysis of spatial patterns (Nicotra 1998;Fonton et al 2011;Havyarimana et al 2013). In addition, this plot size significantly reduced the errors accumulation during the distance measurement between trees (Boose et al 1998).…”

“…As demonstrated by many authors (Le Maître et al 2011;Pearson et al 2018; Dydersky & Jagodziń ski 2020), the spatial repulsion of a species trees can restrict the establishment of spontaneous species and promote changes in species composition and community structure. Indeed, the local dominance expressed by an aggregate distribution of a tree species can reduce the diversity (Havyarimana et al 2013).…”
