Vegetation was sampled in 86 plots of riparian forest and dry forests of northern Togo. The recorded data were subjected to floristic and quantitative ecological analyses in order to describe the main woody plant communities and their size structure. The plant groupings were determined by detrended correspondence analysis (DCA) and defined through the indicator value method. Alpha diversity index, and tree species structure features were computed for forest woody plant groupings. Results classified four woody communities. Two of them belonged to riparian forest while the other two, dry forest. A total of 77 plant species consisted of woody species. Pterocarpus santalinoïdesand Anogeissus leiocarpuswere the most important species based on their indicator values. The diversity indices o[...]

Two of them belonged to riparian forest while the other two, dry forest. A total of 77 plant species consisted of woody species. Pterocarpus santalinoïdesand Anogeissus leiocarpuswere the most important species based on their indicator values. The diversity indices of P. santalinoïdes, Eugenia kerstingiiand A. leiocarpusand Vitellaria paradoxaplant communities were significant and indicated a wide distribution of species in the area, while their structural features reflected those of forests characteristic of the Sudanian climatic zones. In general, the natural regeneration rate among the plant groupings was satisfactory and quiet similar to those found in previous works in this region.
