Co-existing tree and plant species will gain in the void left by the affected species, but often providing different functions. Eastern hemlock, for example, is commonly replaced by black birch in the northeast—a slow-growing, shade-tolerant and deep shade producing evergreen tree, replaced by a fast-growing, open, deciduous tree. While short ...

Beech bark disease is a disease that causes mortality and defects in beech trees in the eastern United States, Canada and Europe. [ 1 ] [ 2 ] [ 3 ] In North America , the disease occurs after extensive bark invasion by Xylococculus betulae and the beech scale insect , Cryptococcus fagisuga . [ 4 ]
