Acute Oak Decline is a complex tree decline disease [2] that cannot be explained by a single cause. It results from a combination of environmental factors weakening the trees and some biotic factors. It results from a combination of environmental factors weakening the trees and some biotic factors.
The disease tends to occur in patches due to a primarily short range spread mechanism. [3] Infected or decayed roots break close to the root collar forming “root balls.” [ 1 ] Laminated root rot is frequently detected during ground survey when canopy openings and standing dead and fallen trees are observed. [ 4 ]
Ill-health of trees can be diagnosed, and early treatment, pruning or felling to prevent the spread may result in timber stocks and amenity trees being saved. Tree owners and Arborists/arboriculturists need to be aware of the risk posed by hazardous trees. Construction projects sometimes avoidably damage trees.
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]

Oak wilt is a devastating exotic disease, killing some trees rapidly in a single season. [7] Oak wilt is an important disease in urban areas where trees are highly valued. . The disease reduces property values because of the loss of trees and is economically costly to the property owner since they or the local government must pay for tree remo
A healthy tree naturally combats heart rot through a process called compartmentalization. The tree grows around the decayed wood tissue and prevents the fungus from spreading to a larger area of the trunk. Providing a tree with the necessary nutrients, water, and growing conditions will promote healthy growth and minimize rot.
Eradication of recently introduced pests, or long-term management of established exotics and indigenous pests, to minimise losses in wood quality and wood production, and to reduce tree mortality. Assessments of forest operations, or of management impacts, on the invertebrate fauna, and the alleviation of any adverse effects on these invertebrates.
