The Red river hogs and the Common warthog are privileged game, quite prolific and their habitats are undergoing quite a bit of modification due to human activities. The phyto-ecological characterization of their habitats in South Benin has been carried out in their current range distribution. The Braun-Blanquet sigmatist method was used to carry out inventories in 70 phytosociological surveys taking into account the floristic community strata and anthropo-environmental data were collected following occurrence indices. A total of 184 plant species were enumerated and reduced to a Detrended Correspondence Analysis while a Hierarchical Ascending Classification was carried out to form ecological groups. After the diversity indices, the ecological spectra were produced and a linear model with a proportion test was performed. Low values of Shannon diversity indices (0-0.4 bits), Pielou Equitability (0-0.1) and Simpson index (0-0.01) and an ecological dissimilarity of habitats were observed in their communities. They are more fond of the herbaceous-arbustive groups but the ecological preference of red river hog, contrary to the common warthog, is marshy to semi-aquatic. It is fundamental to propose a master plan for reconversion, restoration of degraded habitats, review land use policies and evaluate these suids Average Daily Gain (ADG).
