An Ecological Impact Assessment (EcIA) is often required where ecological constraints to development are identified during the Preliminary Ecological Appraisal (PEA) process.
Following further species specific surveys (e.g. bat, badger or reptile surveys) or habitat specific surveys (e.g. grassland or hedgerow surveys) the baseline ecological value and receptors are known.
The impacts of the proposed development can then be considered against each identified receptor. Where unavoidable impacts are significant, mitigation would be designed to reduce the residual impact of the development.
An EcIA can form a chapter within a formal Environmental Impact Assessment (EIA).
