EcIA Guidelines

These guidelines provide practical advice for all professionals involved with ecological evaluation and assessment for proposed developments in terrestrial, freshwater, marine and coastal environments.

The 2016 Terrestrial EcIA Guidelines replaced the 2006 Terrestrial EciA Guidelines and included changes in terms of principles, procedures and emphasis as summarized in this presentation given to the CIEEM Spring Conference in March 2016. The changes made to the Terrestrial EcIA Guidelines in 2016 were equally applicable to marine EcIA (the principles and procedures of EcIA are common to terrestrial and marine situations) and left the 2010 Marine EcIA Guidelines out of date.

The 2018 Guidelines, covering both terrestrial and marine, are essentially the 2016 terrestrial Guidelines, plus marine components, e.g. marine case studies and examples, description of important marine ecological features, list of activities that can cause marine impacts, marine designations, reference to marine policy/legislation. The 2018 Guidelines also give emphasis to the particular marine context of EcIA, including the need to consider the dynamic nature of marine ecosystems during the assessment of marine impacts, and the principles of Adaptive Management (paragraphs 5.36 – 5.37).

In addition, the 2018 Guidelines update the previous Guidelines in terms of changes in policy/legislation references, sources of information, etc.
