The Quality of Biodiversity Inputs to EIA in Areas with High Biodiversity Value — Experience from the Cape Floristic Region, South Africa

Abstract

The quality of biodiversity inputs to Environmental Impact Assessment (EIA) in areas with high biodiversity value was investigated by reviewing the quality of a sample of Biodiversity Impact Assessments (BIAs) in the Cape Floristic Region (CFR), South Africa. The results suggest that while the overall performance was satisfactory, several inadequacies were evident, confirming international trends. Inadequacies relate to consideration of alternatives, public consultation, monitoring programmes, and gathering of biodiversity baseline data during inappropriate seasons and over insufficient time periods. Positive outcomes include the incorporation of ecosystems processes in baseline studies and assessment as well as the wide adoption of a precautionary approach to impact prediction. It is recommended that best practice and biodiversity guidance as developed and implemented in the Western Cape Province, be adopted as widely as possible in other provinces, and that the BIA practitioner community be alerted to revealed weakness of BIA report quality.
