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 ]
Coillte, who owned twenty forests where the disease was present, felled 16,000 trees in one of its forests, having already felled 150 hectares to contain the disease. [15] In 2023 the disease was found to be infecting larch trees at Wyming Brook , Sheffield, with plans to fell over 1,000 trees to contain the spread of the infection.

The male flowers, often brown or yellow in color, form in a drooping, elongated cluster. [6] Female flowers appear as individual reddish spikes with surrounding leaves. [7] The fruit ...
The disease gets its name from the black patches that grow on the trunks of infected trees. In a newly infected tree, branches become denuded and then die off. Eventually, the entire tree succumbs.
The infection then spreads through the inner bark and cambium around the base of the tree. Spread up the trunk is generally limited. Infected tissue dies and effectively girdles the tree. Large trees are more likely to be infected than small trees due to larger root areas (although all trees at the edges of infected streams will eventually ...
The name Melaleuca is derived from the Ancient Greek μέλας (mélas) meaning "dark" or "black" and λευκός (leukós) meaning "white", [4] [5] apparently because one of the first specimens described had fire-blackened white bark. [6] The common name "tea tree" has been applied to species in the genera Leptospermum, Melaleuca, Kunzea ...
