Abstract

The chair of forest yield science of the University of Munich has examined whether the pollution from the Schwandorf brown coal power plant and the state of health and growth conditions of the surrounding pine forest are related. Based on yield information analysis of 103 sample plots and the research of the pollution situation in the examination area, the questions of the examination have been answered in the following: 1. The healthy stock in the area mirror relatively favourable growth conditions. 2. The polluted stands below clearly, since 10 to 15 years, a hindered growth increase. Between the extremes, healthy and intensely damaged trees, come different degrees of damage that can be identified with defined annual increment developments. 3. To calculate the loss of increment in the damaged stands of reference system is applied, that derives the diminuative increment through the comparison of the healthy and damaged trees. 4. In the research area are zones bordering an other, in which defined increment reaction specimens dominate. Parts of the region with typical increment dynamics and with different specific regional damage signs can be distinguished. 5. The immission pollution from the brown coal power plant in Schwandorf has a specific area distribution and a temporal development so that the pollution from other, smaller emitants is obviously covered up. There are clearly related tendencies between the emission rate of the plant and the increment reactions in the outlying forest stands. In the temporal alteration and the specific regional markings of the increment proportion from the pine stands is clearly mirrored the development of the emissions from the power plant in the last 20 to 30 years.
