Abstract:
The wood resources of classified forests are nowadays subject to accelerated degradation. This
research aims to characterize plant groups and their use by anthropogenic activities in the
Ouémé-Boukou classified forest (FCOB). The field surveys were carried out among 81 people
through a reasoned sampling according to the economic activities having an impact on the study
forest. Following the sigmatist method of Braun Blanquet (1932), the floristic inventory was
carried out in 31 circular squares of 18 meters radius installed according to the criterion of
homogeneity of the vegetation and the topography of the environment. The collected data was
submitted to the CAP (Community Analysis Package) software for the realization of the
dendrogram. Thus, 27 woody species divided into 14 families and 23 genera have been
inventoried and are classified in 3 plant groups. The most dominant families are Combretaceae
(35%), Cesalpiniaceae (29.54%), Sapotaceae (20.17%), Papilionaceae (11.11%) and
Mimosaceae (6.33%). The most represented life forms are Mesophanophytes (46.27%) and
Microphanerophytes (38.53%). In terms of chorological realities, Guineo-Congolese species
(43.57%) and Sudanese species are more represented (49.73%). In addition, agriculture, aerial
grazing, wildfires, coal production and population growth are among the determining factors in
the degradation of the study area. The flora of the study area gives a slight hope by its multiple
regenerations despite anthropogenic pressure. |
