Sapwood blocks of white pine and American beech

Beech bark disease (Nectria coccinea) and beech bark scale (Cryptococcus fagisuga) were first recorded on American beech

In a mature southern mixed hardwood stand in Hardin County, Texas, American beech

Braun (1950) described the preserve as a "virgin white oak [Quercus alba] forest occupying a morainal area" and delineated five plant communities, namely: 1) red maple (Acer rubrum)-American elm (Ulmus americana) in depressions, 2) red maple-white oak on flats, 3) white oak with an admixture of mesophytic and wet-mesic species occupying low swells, 4) white oak on well-drained mesic sites, and 5) an American beech
(Fagus grandifolia) community.
Beech bark disease is an exotic disease complex involving the exotic beech scale (Cryptococcus fagi Baer) and at least two species of Neonectria fungi, which affects the American beech
