Abstract


Aim of study: This study focused on the analysis of
structural and spatial patterns of Isoberlinia
spp stands according to topographic units.


Area of study: Data collection were carried out within the
Zouzounkan forest reserve, located in Southern
Benin.


Material and Methods: Square plots of 1 ha were considered for the
forest inventory in which, geographical coordinates of Isoberlinia individuals were recorded. Ripley’s K function was used
to assess the spatial patterns of the species in the forest whereas
dendrometric and ecological parameters was computed to analyze the structure of
the species populations. Possible impact of topographic units of the forest
reserve on dendrometric and spatial patterns of trees was assessed.


Main results: The results show that Isoberlinia spp. is more abundant on the hill side than on the top
and down hills. Aggregative spatial distribution of trees was found across
topographic units with more aggregation on the hill side. However beyond a
radius of 8 m aggregation decreased. Furthermore, significant difference was
noted on dendrometric patterns of Isoberlinia
trees according to topographic unit.













Research highlights: Results obtained suggest that effective
conservation strategy of Isoberlinia
trees in Zouzoukan forest reserve should take into account topographical
patterns.
