DescriptionBeech bark dieease first reached North America about a 100 years ago and within a few decades rendered beech an almost useless weed species in the Maritimes. A survey in 1980 to determine the current status of the disease found the scale insect active, though infestations generally light, on over 90% of trees in Nova Scotia and Prince Edward Island but on only about 50% i n New Brunswick; Nectria coccineavar. faginata distributed throughout; some degree of stem cankering on trees; mortality in New Brunswick (3.7%) less than half of that found in Nova Scotia (9.1%) or Prince Edward Island (9.8%). The future of beech as an economical f o r e s t species is bleak.
