  abstract = {{U}nderstanding how species assemblages are structured fit relation to environmental variation is a central issue in community ecology. {H}owever. factors that create regional variation in relative species abundances have been little studied due to the rarity of large-scale datasets. {H}ere, we investigated it large dataset (30 180 0.5-ha plots spread over 1 600 000 ha) gathered from forest planning inventories in the semi-deciduous forest of the {S}outh western {C}entral {A}frican {R}epublic. {W}e used {C}orrespondence {A}nalysis and {N}on-{S}ymmetric {C}orrespondence {A}nalysis on {I}nstrumental {V}ariables to analyse variation in the abundance of 73 common tree species in relation to soil type, rainfall and proximity to villages. {T}ogether, environmental variables explained 10.3% of multi-species floristic variation among plots. and the regional spatial structure almost disappeared when the effects of these variables were removed. {A} {T}rend {S}urface {A}nalysis using a third order polynomial function of the geographical coordinates of the plots explained 14.5% of the floristic variation and more than 75% of this variation was explained by environmental variables. {S}andy soil was the {M}ost influential {F}actor affecting floristic composition. {R}esidual spatial variation not explained by the environmental variables probably reflects the natural and anthropogenic history of the vegetation.},
