The "Jablunkovsko" territory has been recently affected by the extensive yellowing of spruce forests leading even to the gradual decline and dieback of individual trees. Stress factors to be considered at the present time on the basis of hypotheses concerning the damage and dieback of forest stands are climatic and air-pollution stresses. In a situation of combined climatic and air pollution stress induced for example by the introduction of acid deposition, the climatic stress would assume the role of a predisposition factor. The causal relation between the change of health condition and the deposition of sulphur, nitrogen and hydrogen ions can be demonstrated by the fact that localities in which the damage to forest stands occurs show some of the critical loads exceeded. The objective of this study is therefore to evaluate the deposition flows of sulphur, nitrogen and H+ acid deposition in the forest stand and in the soil (in the forest ecosystem), to compare them with the critical loads of hydrogen ion deposition for spruce (CLH), and the critical load of nutritional nitrogen (CLNt) for coniferous stands. The spatial distribution of potential acid throughfall deposition indicate that the CLH value for spruce being exceeded on nearly 30% of the area of the Jablunkovsko territory. With respect to eutrophication, the area of about 9% shows an exceeded critical load of nutritional nitrogen (CLNt) for coniferous stands. |
