First-order criteria for marine biological valuation
This article defines the First-order criteria for marine biological valuation. It is part of a review of the different approaches to the evaluation of components of the marine environment derived from discussions at a workshop on marine biological valuation, held from 6 to 8 December 2006 at Ghent (Belgium). The workshop was a joint venture of the EU CA ENCORA (http://www.encora.org) and the EU NoE MARBEF (http://www.marbef.org).
First-order criteria can be considered the main valuation criteria determining the biological value of the subzones within a study area. This ‘basic’ value of a subzone could later be changed by evaluating its score for the modifying criteria.
The use of first-order and modifying criteria is illustrated in the graph below (giving an overview of the concept of marine biological valuation).
