Survey of the Anthropic Actions and the Urban Woody Flora Exploitation in Brazzaville (Congo)
International Journal of Current Research and Academic Review
Article Info The background of this survey is the management of the urban arboreal diversity in Brazzaville and its link to the endogenous knowledge of the populations. It focuses on the traditional pharmacopeia and the ecological advantages of the urban forestry. The ethnobotanic inventory, based on the anthropogenic sampling of the organs revealed 7 species of which 86%arealloctonous. The phytogeographic data showed that 57% among them come from Asia, and only 43% from central Africa dense
... ral Africa dense forests. On the traditional pharmacopeia aspect, it appears that the taxa intervene in about thirty illnesses and symptoms. According to Africa WHO classification, 11 fields of illnesses and symptoms out of 17 are covered by this survey. Infectious and parasitic illnesses are those that have a very high rate of prevalence. A look on the origins of the aforesaid taxa shows that, there is an appropriation or even an acquisition of new knowledge about phytotherapies. Despite the beneficial effect of these plants, they are always managed like trees of avenue and public gardens. There is no protective and/or back-up measure taken in spite of the senescence that affects them and the uncontrolled harvest of their organs such as roots and barks. The traditherapists needs satisfaction create wide empty areas, and the most important of which are noticed on Peltophorum pterocarpum with 3.15 ± 0.14 m 2 /tree whereas the average dbh is of 0.55 ± 0.03 m. This way of taking organs sample weakens the individuals while disrupting their metabolic functions and leading some malformations simultaneously as the brooms of witches; without forgetting the exhibition of the internal tissues to the cryptogamic germs and to the borers insects.
