The critical load was exceeded on 4000 km2 in the study area, which is 75%
of the forest soils. On 340 km2, (7%) of the forest soils, the exceedance was over
4000 eq ha−1 yr−1. The highest exceedances appear in the central part of the area,
which mainly can be explained by the sulphur deposition. Non exceedance areas
occurred on the rich soils mentioned above.
