Aims: This study aims to analyze the structure of some populations and the natural regeneration potentials of Pterocarpus erinaceus Poir. According to the environmental conditions, taking into account the 5 ecological zones of Togo. Especially, it aims to: (i) Describe the geographical distribution of the species in Togo, (ii) Analyze the influence of environmental variables (climates, soils and type of vegetation) on the structural characteristics of natural stands and (iii) Determine the natural regeneration potentialities of the species. Place and Duration of Study: Fieldworks were done from 10 October to 15 December 2013 throughout Togo. Methodology: Forestry inventory was carried out on 200 plots of 1000 m2 randomly set up in P. erinaceus natural stands in the 5 ecological zones of Togo. In each plot, total height, the merchantable height and diameter at breast height (DBH) ≥ 10 cm were measured. The regeneration was studied in sub-parcels of 25 m2 set up in the prev...

Melliferous plants are plants whose flowers provide nectar or pollen for honey production to bee colonies. Besides their role in honey production or provision of pollen, some have other uses. Pollinic analysis and apicol surveys conducted between 2009 and 2014 on honey sampled directly in beekeeping areas or outlets have permitted discovery of 330 melliferous species Including 45 species (13.64%) which are threatened to extinction in Togo. Compared with Togolese flora, these plants threatened represent 1.29%. Belong to 43 genres, these species threatened which are foods plants can be grouped into 24 families and most at risk are the Malvaceae, Anacardiaceae, Fabaceae and Annonaceae. These plants can be divided into two classes: wild and crops plants. The routinely used parts of these plants are the fruits and leaves. In general, nectar plants are the most represented. From this study, it appears that 45 species of melliferous and alimentary interest were targeted endangere...
