Popis: Increase in human population and activities are having significant impacts on the conservation of biodiversity. As traditional farmlands have challenges of coupling crop production and conservation of biodiversity, this study aims at assessing traditional farmlands in regard to their typology and impacts on conservation of tree species. A line transect of 26 km was applied for the identification of the farmlands and tree species were inventoried within each farm. A cluster analysis was performed; tree species diversity indices and dendrometric parameters were computed and analysed according to each of farmland groups. Five groups of traditional farmlands were found with the small areas with high number of crop species and tree species with dominated cover and the large areas with small number of crop species and tree species with high crown cover and a high number of tree species. The trees species diversity was high within the largest size farmlands. The tree density (p = 0.249), total height of trees (p = 0.585) and tree crown area (p = 0.813) were not significantly different among farmland groups. The stem diameter varied significantly among farmland groups and the large size farmland groups have high diameter values. The distributions of the diameter of trees for all the farmland groups showed the shapes that were characterized by the tree populations with higher amount of small size stands for all farmland groups. Large farmlands may be promoted to target tree species conservation in agricultural areas in the localities of Ouémé catchment.
