Environmental Impact Assessment (EIA) is a procedure which provides the opportunity for identifying, mitigating or enhancing the potential environmental, health and social consequences of a proposed development activity and for generating alternatives or additional options to that activity (Johnstone 1986). It is a process having the ultimate objective of providing decision makers with an indication of the likely consequences of their actions. The greatest contribution of EIA in environmental management may well be in reducing adverse impacts and refining the developmental proposals before they come through. In order to quantify these impacts it is first essential to measure. environmental quality parameters before the project has begun. This data on baseline conditions and trends make possible the assessment of changes produced specifically by the developmental project as compared to any natural changes which might occur (Dixon et al., 1983). Identification of ecologically sensitive areas (terrestrial and aquatic wildlife habitats) on which the impacts of the proposed project are anticipated, determining baseline status with regard to identified elements through sampling and field investigations and estimating resultant changes in different parameters and aggregation of these changes in determining the resultant environmental impacts on wildlife and bio-habitats formed the basis of this EIA study.
