Abstract:
Abstract Mortality due to annosus root rot among trees of seven species on two sites was 6% or less by age ten. Previous stands on these sites had been clearcut because the disease was widespread. After 22 years neither basidiocarps of Heterobasidion annosum nor trees with symptoms of annosus root rot were present in the plantations. Planted seedlings of loblolly (Pinus taeda L.), longleaf (P. palustris Mill.), slash (P. elliottii Engelm. var. elliottii), and eastern white (P. strobus L.) pines survived well and at age 22 provided fully stocked to overstocked stands with good basal area and av

Abstract:
This study investigated the origins and spread patterns of Heterobasidion root disease in three Pinus contorta Dougl. ex Loudon plantations established on forest and agricultural land and subjected to three different management scenarios. Trees with decline symptoms and stumps remaining from the previous rotation were sampled for fungal isolations. Ten isolates of Heterobasidion parviporum Niemelä & Korhonen and 425 of Heterobasidion annosum (Fr.) Bref. were tested for clonality through somatic compatibility tests.

This study provides new information on the infection biology and pathogenicity of an important root-rot fungus, Heterobasidion annosum sensu stricto (Fr.) Bref., through a detailed examination of the vegetative spread of clonal individuals and their capacity to produce fruiting bodies on young pine seedlings. The seedlings were planted in a clear-cutting area (c. 1.2 ha in size) after a pine generation that showed slight external symptoms of Heterobasidion root rot. The first dead seedlings were found five years after planting and during a nine-year monitoring period; nearly 600 seedlings were

Airborne Heterobasidion annosum (Fr.) Bref. sensu lato infections can be controlled by winter thinning or by mechanically spreading urea or Phlebiopsis gigantea (Fr.)

We studied the rot incidence and population structure of H. annosum in plots of Picea abies (L.) Karst. thinned in winter or thinned in summer with and without treatment of the stumps.

Abstract:
In the Wielbark Forest District, and many other forest districts in Poland, disturbances caused by annosum root rot Heterobasidion annosum (Fr.) Bref. have been observed regularly in timber stands cultivated on post-agricultural land. Natural regeneration in the resulting gaps is dominated by birches, but also other tree and shrub species occur. A better understanding of those natural successional processes is required in order to possibly include them in management practices, i.e., to employ them as an aid in stand conversion or improvement. This goal formed the foundation for this study, whi

Heterobasidion annosum (Fr.) Bref. sensu lato (s.l.) is a dangerous forest pathogen causing root and butt rot disease in most conifers of the northern hemisphere. This pathogen is most widespread in the forests of Europe and North America. The economic impact on forestry related to tree mortality, reduction in timber yield, and wood rot is calculated in millions of dollars and euros. The genus Heterobasidion (Basidiomycota; Russulales) has been relatively recently separated into three genetically distinct groups (H. annosum, H. insulare and H. araucariae) comprising a total of 12 species and o

Heterobasidion annosum (Fr.) Bref., is a pathogenic hymenomycete which causes white-rot of coniferous trees throughout temperate regions of the Northern Hemisphere. The fungus can be divided into three intersterility groups (IS-groups) in Europe and two IS-groups in North America based on in vitro sexual compatibility and, loosely, on host tree preference. European P, S and F IS-groups prefer pine, spruce and fir respectively, and North American P and S groups prefer pine and fir respectively.

Abstract:
Abstract Heterobasidion root and butt rot pose a greater risk in continuous cover forestry (CCF) than in rotation forestry (RF) in conifer-dominated forests, regardless of whether selective, gap or shelterwood cutting is used. Damage from wind, snow, spruce bark beetle, and large pine weevil are likely to be less severe in CCF than in RF. However, the conversion of RF to CCF may briefly expose stands to windthrow. Browsing by large herbivores on saplings may limit regeneration of tree species other than spruce in continuous cover forestry and reduce tree species diversity, but alternative silv
