Spruce tree fighting back – study of honey fungus infection

Abstract

Fungi infection is a common disease, problem for trees. Becoming fearful of the presence of fungi is obvious, although the effects of the infection are variable widely. Honey fungus (Armillaria mellea) is considered to be dangerous species weakening the trees. A honey fungus attacked spruce could be measured repeatedly for three years with acoustic tomography while pulling tests were performed as well. The research goes on, although the results interestingly show us the tree “fighting back”. The safety and stability of the examined spruce is very good, the conditions of the root system are – surprisingly – getting better.
