Beech Bark Disease.

http://preferredmode.com/2013/04/20/rachel/ The bark of beech is famously smooth, providing a space for people to carve their initials.  But most beech in the Northeast, and almost all in the Catskills, is infected with beech bark disease, an imported European pathogen to which the American species has no resistance.  The young trees grow fine, until they reach about four inches in diameter, when they start to show signs of the disease.  For large trees, above a foot in diameter, the infection rate is nearly a hundred percent and the trees eventually succumb.  Beech is the only hardwood tree that can regenerate here in the Catskills under current levels of deer browse, but due to bark disease very few individuals will reach canopy-tree size in the next few hundred years.  Many trees do produce nuts, however, even with the disease, so there is hope that the tree can breed itself into resistance, with more bark-disease-resistant individuals succeeding better than their fellows.  Because of the extinction of the American chestnut, the beech is the only mast species in the high Catskills – the only tree that provides nuts for bear, deer, squirrels, chipmunks, turkeys, etc.
