Abstract
Aims: The aim of this work is to identify and evaluate the impacts related to the traced of high voltage on the flora of Agboville in order to put forward measures of attenuation or correctives.
Study Design: The vegetations were delimited into small squares plots or pieces. These small squares plots were distributed in all the flora of the study.
Place and Duration of Study: This work relates to the identification and the evaluation of the negative impacts of the layout of the line of high voltage on the flora of the study zone. It was conducted in Agboville, a locality in the south of Côte d'Ivoire, during July to September 2013
Methodology: The itinerant inventory and the method of "quadrat" were associated during floristic inventories.
Results: The results showed that the flora is approximately rich 81 species. However, it is little diversified and more homogeneous. The destruction of the woody flora (DFL), the destruction of the floristic potential of regeneration (DPE), the evolution of floristic diversity (EDF) and the aspect of vegetation (EPV) were the major average impacts during the study, the exploitation phase and at the end of the project. These impacts, brought out all along the phases of the project contributed to weaken the flora of the site and stated it to the risks of the biological, ecological and climatic imbalances.
