This article stems from discussions held during 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 ( and the EU NoE MARBEF ( Both Theme 7 within ENCORA and Theme 3 within MARBEF deal with marine/coastal biological valuation and the workshop aimed to reach a consensus on this topic. It identifies two issues that need to be considered when considering marine biological valuation.

"*Because the marine environment is a highly dynamic and open system and because different ecosystem components show a high variation (e.g. benthic communities) valuation maps have to be updated after a certain period of time to reflect the most recent status of the study area.

  • However, due to the high sampling intensity needed to update Marine biological valuation maps (BVMs) these maps cannot be updated frequently enough to reflect real interseasonal or interannual differences in value."
