We conduct specialist biodiversity assessments for scoping studies, Environmental Impact Assessments (EIAs),  Environmental Management Plans (EMPs), Water Use License Applications (WULAs) and environmental rehabilitation projects. All specialist reports comply with the requirements of the  the protocols specified in GN 320 (Procedures for the Assessment and Minimum Criteria for Reporting on Identified Environmental Themes in Terms of Sections 24(5)(A) and (H) and 44 of the National Environmental Management Act, 1998, when Applying for Environmental Authorisation)
