Forest Ecology and Management (1990) Führer
|
Abstract
Although it seems to be a generally accepted assumption that the widespread forest decline is triggered by different factors working in different ways, additional aspects must be taken into account to understand the recent disease events of central European forests. Air pollutants can interact with natural stressors and site conditions can modify the reactions of trees to air pollution, and in view of this the ambivalent roles of site factors, natural stressors and air contaminants in predisposing trees to diseases are discussed. A comprehensive eco-stress hypothesis is described, which postulates that forest ecosystems become increasingly sensitive to external stressors when the load of intrinsic stress is elevated. Central European forests are mostly ecologically unstable, suffering from their historical fates and from the effects of recent management methods. Their sensitivity to additional external stressors is, therefore, expected to be very high. A double strategy of forest conservation in central Europe is suggested: reduction of air pollution and restoration of the intrinsic stability of forest ecosystems.
