An annual forest health survey has been conducted in Great Britain since 1984 (Binns et al., 1985, 1986; Innes el al., 1986). From the outset, the survey has been designed to determine both the extent of any deterioration in crown condition and, if possible, its causes. Over the years a number of changes have been made in the survey as more information has become available on the extent and nature of forest decline in central Europe and on possible causal factors. This year sees the most substantial changes yet.
