See OP 4.01, Environmental Assessment. Annex A Definitions 1. All natural habitats have important biological, social, economic, and existence value. In both terrestrial and aquatic ecosystems, conversion of natural habitats can occur as the result of severe pollution. Appropriate conservation and mitigation measures remove or reduce adverse impacts on natural habitats or their functions, keeping such impacts within socially defined limits of acceptable environmental change.
Specific measures depend on the ecological characteristics of the given site.
Such measures should always include provision for monitoring and evaluation to provide feedback on conservation outcomes and to provide guidance for developing or refining appropriate corrective actions. See OP 4.01, Environmental Assessment. Rare, vulnerable, and endangered as defined in the IUCN Red List of Threatened Animals. Consultation Comments 1. No consideration has been given to habitats and natural areas degraded to the point where native biodiversity is threatened.
