Abstract
The aim of this study was to determine target loads for acidification for representative forest ecosystems in Flanders (Belgium) using dynamic modelling. Target loads were calculated for 83 forest stands for which sufficient measurements were available. This dataset is considered to be representative for the Flemish forest area. It is concluded that, despite the inherent uncertainty in modelling soil acidification at a regional level, important N and S deposition reductions are needed to allow recovery of the Flemish forest soils.
