Initial symptoms of forest stands drying are defoliation and discolouration of tree crowns. Therefore, the defoliation, with the changing of tree crowns color are accepted as the main parameters which estimate crown condition within forests state monitoring. This paper analyzes data for defoliation as part of the results of the monitoring of forests on ICP sample plots. Rating of defoliation is done regardless of the cause of leaves loss, and the results are not aimed at determining the cause-effect relationship. They are only represent the state of defoliation on sample plots processed in the period. Connecting these results with other indicators of environmental conditions will provide more specific information, and make conclusions about the vitality of plants depending on environmental conditions.
