The preliminary results of the 1988 forest health surveysare presented. A total of 9211 trees were assessment in the two surveys, with the more detailed main survey involving 7411 trees. The results from both surveys suggest that there has been some deteroration in the crown density of Sitka spruce and Scots pine during the past year. Norway spruce and oak do not appearto have changed, whereas beech has clearly improved. A full report, presenting the data in more detail, will be published in the first half of 1989.
