Abstract
Surveys of forest condition have been undertaken in most European countries over a number of years. Patterns are beginning to emerge which do not support the theories of large-scale forest decline proposed in the early 1980s. Instead, forest condition apparently fluctuates from year to year, with the degree of fluctuation depending on a variety of factors. Individual trees may show substantial changes in condition from one year to the next which are not necessarily reflected in the overall national statistics (Hägi 1989; Innes and Boswell 1991), leading to problems of interpretation (Innes 1990a).
