Changes in vegetation are often caused by changes in abiotic site factors, such as pH, nitrogen availability and soil moisture. In order to evaluate the effects of eutrophication, acidification and drought on site factors, the SMART2 model has been developed. For the Netherlands, combinations of two acidification and two seepage scenarios (1990-2050) were evaluated with SMART2. Results showed that deposition reductions lead to a relatively fast improvement of the site factors, increase in pH and basesaturation, and decrease in nitrogen availability. A reduction in groundwater extractions by 25% has little or no effect on pH and nitrogen availability.
