Project Objective

The objective of the project was to undertake a terrestrial ecological impact assessment (faunal and floral) for the proposed Nemai seismic survey within the Karoo region of the Western and Eastern Cape. The assessment aimed to identify and evaluate potential impacts of the seismic exploration activities on local biodiversity, with particular focus on sensitive habitats, protected species, and ecosystem integrity. The findings were used to inform environmental authorisation processes and guide mitigation and monitoring measures to ensure sustainable project implementation.

Execution Strategy

A desktop review and detailed field-based ecological survey were conducted to characterise the baseline conditions of the study area. The field assessment covered representative habitat types along the proposed seismic lines, recording vegetation structure, species composition, and faunal presence or activity. Faunal surveys included direct and indirect observations of avifauna, small mammals, reptiles, and invertebrates, while floral assessments focused on species of conservation concern, invasive alien plants, and vegetation condition. The study followed the protocols outlined in relevant SANBI and DFFE guidelines, with a focus on minimising disturbance to sensitive ecological receptors.

Key Achievements

  • Comprehensive documentation of the floral and faunal communities within the Karoo seismic project area.
  • Identification of key ecological sensitivities and conservation features to inform seismic line routing and operational planning.
  • Development of practical mitigation and monitoring recommendations to minimise ecological disturbance during exploration activities.
  • Contribution to a more sustainable approach to energy exploration through improved understanding of terrestrial ecological dynamics in the arid Karoo landscape.
