PREHAB – Spatial prediction of benthic habitats in the Baltic Sea

Research project

Short description

Maps of the spatial distribution of biodiversity and the associated ecological goods and services provide an important basis for sustainable planning of the Baltic Sea. A cost-effective and practical method for producing such maps is through predictive modelling. The aim of the PREHAB project is to evaluate new tools for marine spatial planning and environmental impact assessment. We target authorities and policy-makers in the Baltic Sea region.

Main results

  • predictive modelling is a promising method for obtaining useful maps on the distribution of species and habitats,
  • scenario modelling is a useful tool for understanding and predicting ecosystem responses to alternative management options,
  • the citizens of the Baltic Sea countries value a clean and healthy sea and are willing to pay for mitigation actions.
