Aims to help Environmental Impact Assessment (EIA) achieve its potential by providing best practice guidance on the treatment of biodiversity in EIAs for road schemes. It provides a detailed approach that is applicable not just to road schemes, but to EIAs of other developmental types, and will complement existing guidance and should help all participants in the road EIA process - government, local authorities, planners and ecologists, statutory and nature conservation bodies, developers and promoters, and environmental and ecological consultants involved in the preparation of road Environmental Impact Statements.
