Critical loads and exceedances for eutrophication and acidification for Flemish forests

Critical loads were estimated for over more than 1400 receptors supporting forest vegetation in northern Belgium using simple mass balance method. Necessary data were derived from old historical soil database, recent data from forest surveys, meteo data, level I and II plots and regional studies concerning elemental sequestration in woody biomass. Deposition estimates were performed with the OPS–model, which had been validated with deposition measurements of N and S in 6 level II plots over the period 1994–1998. In addition, an edge enhancement factor was calculated to account for enhanced dep... Mehr ...
