Abstract
The report deals with the throughfall precipitation in the forest was collected at the permanent research plots of the Norwegian Monitoring Programme at 19 locations in Norway. Bulk precipitation in a nearby clearing was also collected. The precipitation was measured and chemically anlysed. The results revealed that there were significant differences between locations. The forest ground vegetation received 24% less precipitation than the open areas close to the plots. The pollution load in forest stands was clearly higher than in open areas close to the stands. The plots located in southern Norway were most influenced. However, some of the plots are located near the cost, and these are influenced by marine salts, which decrease the effect of the pollution loads. Less influence was measured at plots located in north-western and central Norway. The forests of eastern Finnmark are strongly influenced by industry emissions at the Kola Penisula. A relationship between high concentrations of important plant nutrients in the throughfall precipitation and its pH was found. This might indicate an pH-dependent leaching of plant nutrients from canopy, which may lead to deficiency symptoms of the foliage, e.g., yellowing. 29 refs., 13 figs., 4 tabs.
