A statewide Forest Tent Caterpillar Impact Survey was conducted in 1984 and 1985. The randomly selected points included 40 defoliated stands with visible mortality (as detected during aerial surveys), 43 defoliated stands without visible mortality, and 16 undefoliated stands. Data was derived from at least five prism points (10 BAF) per stand. The data has not been fully analyzed. A preliminary analysis of the crown condition of the sugar maple basal area shows a trend of increasing tree mortality and crown dieback with increasing number of defoliations.
