  • Marine biological valuation provides a comprehensive concept for assessing the intrinsic value of the subzones within a study area. Marine biological valuation is not a strategy for protecting all habitats and marine communities that have some ecological significance, but is a tool for calling attention to subzones that have particularly high ecological or biological significance and to facilitate provision of a greater-than-usual degree of risk aversion in spatial planning activities in these subzones.
  • Based on a thorough review of existing criteria, a selection of criteria (first order criteria: aggregation, rarity and fitness consequences; modifying criteria: naturalness and proportional importance) was rationalized, aiming at a widely applicable valuation concept. We have also attempted to clarify the numerous criteria and definitions of value that are current in the literature.
  • As this biological valuation concept is based on the consensus reached by a group of experts on this matter, we realize that refinement of the methodology could be necessary once it has been evaluated on the basis of case study areas.
