Enemy release from beech bark disease coincides with upslope shift of American beech
Canadian Journal of Forest Research, 2022Upslope shifts in plant distributions are often attributed to warming climate and lengthening of the growing season; however, biotic interactions may also contribute. The impacts of pests and pathogens are often sensitive to climate change and can vary along the climatic gradient associated with elevation. American beech ( Fagus grandifolia) has moved

The beech bark disease, caused by fungi (principally Nectria coccinea var. faginata) infecting minute feeding wounds made by scale insects (principally Cryptococcus fagl) in the bark of beech (Fagus grandifolia), is well established in the eastern United States and is spreading. Many beech trees are killed and weakened in infected stands, although some

The effect of the beech bark disease on the growth and survival of beech in northern hardwoods
European Journal of Forest Pathology, 1979AbstractA risk classification for beech (Fagus grandifolia Ehrh.) based on tree characteristics before the onset of the beech bark disease indicated that the crown widths in relation to DBH of trees that died were narrower than the crowns of survivors. Quantitative information on beech trees in the central Adirondack Region of the New York State before

Bark phenolics of American beech (Fagus grandifolia) in relation to the beech bark disease1
European Journal of Forest Pathology, 1984AbstractThe amount of total extractable phenols was determined for bark sections obtained from behind cankers naturally induced by Nectria coccinea var. faginata and from behind mechanically inflicted wounds on stems of American beech. Healthy bark from susceptible trees was found to contain a similar level of phenolics as bark from trees determined to

Managing Beech Bark Disease: Evaluating Defects and Reducing Losses
Northern Journal of Applied Forestry, 1987Abstract Beech bark disease often produces bark defects that may result in trees being classed erronously as cull. Because of this, sale overruns occur, and sound trees are mistakenly left uncut in the woods. The disease occurs when Nectria fungi attack and kill bark predisposed by the beech scale.

The Role of Nectria in the Beech Bark Disease
Journal of Forestry, 1948Abstract The Nectria associated with the beech bark disease of the Canadian Maritime provinces, Maine, and New Hampshire is discussed with reference to its action, known distribution, probable introduction from Europe, present status, and future spread. The importance of beech in northern New England is also discussed.

This is a story of ecological succession—of interrelationships between a fungus and an insect, and the secondary roles played by other fungi and other insects. The disease, or more properly the disease complex, occurs on the American beech in the Northeastern United States and the Maritime provinces of Canada.

Beech bark disease: an evaluation of the predisposition hypothesis in an aftermath forest
Forest Pathology, 2011SummaryThe beech bark disease (BBD) complex affecting American beech consists of the scale insect, Cryptococcus fagisuga, and one or more pathogenic fungi of the genus Neonectria. Following extensive above‐ground mortality of mature beech, stands can be defined by a characteristic set of conditions that are termed the aftermath zone.
