Our data suggest either that American beech
trees are much less resistant to beech scale than oriental beech, that key pathogens are missing in Georgia, or that important natural enemies are missing in North America that are found in Georgia.
Acrocera is known to lay its eggs on grass stems (Schlinger 1987), potentially not far removed from American beech
White pine (Pinus strobus) and American beech
(Fagus grandifolia) sapwood blocks in dimensions of 14 by 14 by 14 mm were weighed after having been oven dried at 105[degrees]C.
In addition to its shade tolerance and longevity, American beech
may also be resistant to exogenous damage caused by tropical storms (Batista et al.
However, the current disturbance regime of primarily large, wind created gaps seems to favor the regeneration of sugar maple and American beech
over oak species.
Regeneration in Michigan: Interactions of Beech Bark Disease and Management.
A few species, such as American beech
, maintain smooth, unbroken bark for their entire lifespan, as their initial periderm continues to grow around the increasing circumference of the trunk and branches, but many of the uncategorized photos still spread across my floor show bark that has broken apart and grown thicker in a multitude of ways.

The HWF Natural Area is 365 ha of predominantly northern hardwood forest dominated by American beech

The second stand represents medium- to high-value mixed hardwood species consisting of yellow-poplar, American beech

The American beech
, she points out, keeps its grocery-bag-brown leaves almost all winter, making it easy to spot in an otherwise denuded forest.
