This may be partly due to the fact that trees with smooth bark provide fewer cracks and crevices in which the scale insect can flourish.

Trees have natural chemicals that keep most fungi at bay, but climate change could be making trees more vulnerable, researcher says. Citizen scientists to study this tree disease found in ...
E. crebra bark. Ironbark is a common name of a number of species in three taxonomic groups within the genus Eucalyptus that have dark, deeply furrowed bark. [1]Instead of being shed annually as in many of the other species of Eucalyptus, the dead bark accumulates on the trees, forming the fissures.
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 ...
