I am concerned with the lack of completeness, correctness and even usefulness of many EIA reports presented to authorities in my country and in the Canary Islands in particular. I would like to learn how people, scientists and professionals of EIA approach the EIA without losing sight of these ecological issues. Why should authorities pay attention to EIA reports including these ecological/biogeographical aspects; and if technicians and scientists make use in their EIA reports of core ecological and evolutionary concepts. I would appreciate learning personal experiences in this field.
