Decline of spruce forest and outbreak of bark beetles in Silesian Region (the Czech Republic)

Popis výsledku v původním jazyce

In accordance with the Manion's theory, the decline of spruce forest is probably a result of several predisposition (spruce is non origin there, soil acidity (4 pH), nutrient deficiency - low reserve of K and Mg and very low reserve of P and Ca, water deficit - periods of drought during last years, mechanical damage - by logging machines, chronic insect - tenthredinids infestation during last 50 years, pathogen damage - damaged by honey fungus) and immediate damage factors. The fitness of forest standsdecreased by drought is further stressed by decreased water-supply as a result of broken roots by drying up of soil. Fungi infection is than obvious. Forest stands abundantly attacked by honey fungus are often consequently colonised by bark-beetles. Pityogenes chalcographus and Pityophthorus pityographus are the most abundant in the young forest stands while species of the genus Ips (Ips duplicatus, Ips typographus, Ips amitinus) together with Pityogenes chalcographus are predominant in
