Abstract:

An empirical model is presented to forecast the incidence of butt rot at the stand level. In addition, the impact of different thinning regimes and stump treatment on the incidence of butt rot was evaluated. The model is based on data from 166 permanent forest yield research plots of pure even-aged Norway spruce (Picea abies (L.) Karst.) plantations in Denmark, within which the incidence of butt rot at stump height in thinned trees has been recorded after each thinning since 1947. In total, 79 000 stumps from 895 thinnings were studied. Regression analyses were carried out with the incidence o

Abstract:

The incidence and severity of butt rot were assessed in 12 selected Norway spruce seed stands in the Beskidy Mountains, Poland. A semi-invasive technique of sonic tomography was used for the assessment of rot damage. Stands of different age classes (100–120, 130–150, 160–170 years old) and distinct regions of provenance (Istebna and Orawa) were investigated. Hierarchical analysis of variance was used to determine effects of stand age and stand provenance on butt rot occurrence at a stand level. High incidence of butt rot was noted in all of the studied seed stands (47% to 87%

Serpula himantioides is a wood-decaying fungal pathogen which is widespread and causes potentially serious butt rot in living trees of numerous coniferous plantation species. This study aimed to quantify S. himantioides in the wood of Sawara cypress (Chamaecyparis pisifera) with butt rot using real-time polymerase chain reaction (real-time PCR). Species–specific primers were designed for the internal transcribed spacer 2 (ITS2) regions of ribosomal DNA (rDNA) of S. himantioides. The specificity of the designed primer set was tested by end-point PCR and amplicon sequencing. End-point PCR assays

Root and butt-rot (RBR) has a significant impact on both the material and economic outcome of timber harvesting, and therewith on the individual forest owner and collectively on the forest and wood processing industries. An accurate recording of the presence of RBR during timber harvesting would enable a mapping of the location and extent of the problem, providing a basis for evaluating spread in a climate anticipated to enhance pathogenic growth in the future. Therefore, a system to automatically identify and detect the presence of RBR would constitute an important contribution to addressing

Among them the most significant species is H. deustum, the fungus causing root and butt rot of standing beech trees. It was recorded from all coppice and high forests of beech. This paper presents the morphological characteristics of the recorded fungi their range, plan

Abstract:

Mortality caused by Inonotus tomentosus (Fr.) Teng (Tomentosus root rot) to dominant and codominant trees was found in all but one of 17 white spruce (Picea glauca [Moench] Voss) plantations 43–58 years old. Even though mortality usually commences at 30–35 years, younger trees can be killed. An average of 0.7% of white spruce were killed annually over the 6-year study period.Average accumulated mortality of dominant and codominant trees was 10.3 % for all plantations. Butt cull in remaining living trees averaged 13.8% of gross merchantable volume in two plots that had been clearcut at Searchmo

Abstract:

Timber harvesting costs and losses for different spacing of skid roads in spruce forests Skid roads are essential to prevent negative impacts of heavy machines on soil fertility and timber growth. Today, skid roads are frequently laid out with a spacing of 20 m because modern harvesters can reach and cut trees as far as 10 m. Skid roads not only use up space which is no longer available for production, they also have negative effects on the growth of adjacent trees due to soil compaction and root damage caused by the passage of forestry machines. Damaged roots will eventually cause butt rot an

Abstract The studies to determine the qualitative and quantitative characteristics of pathologies on trees have carried out as a part of a survey of plantations along the Big Voronezh ecological trail. These characteristics are not taken into account in the guidance documents, but in fact they define these trees as emergency ones. In addition to stem rot and dangerous trunk slope, recommended by the instructions, trees with butt hollows, cancerous tumors on the trunk, splitting of the trunk and shriveled skeletal branches were taken into account.

Abstract:

Because the two common tree species in Norway, Picea abies L. Karst (Norway spruce) and Pinus sylvestris L. (Scots pine), differ in their susceptibility to the fungus Heterobasidion spp., converting at least parts of the rot-infested spruce stands to pine pays-off economically in some cases. Pixel-level information on rot levels and site indexes (SI) across the stand are required to identify these cases to make decisions that increase the expected economic return of the stand. Applying the Value of Information (VoI) concept, we assessed the value of such information when choosing between plant

Abstract:

In an 11-year study in northern Ontario, root rot damage was heaviest in balsam fir, intermediate in black spruce, and least in white spruce. As a result of root rot, 16, 11, and 6%, respectively, of dominant or codominant trees of the three species were killed or experienced premature windfall. Butt rot, which resulted from the upward extension of root rot into the boles of living trees, led to a scaled cull of 17, 12, and 10%, respectively, of gross merchantable volume of the remaining living trees in the three species. The total volume of wood lost to rot was, therefore, 33, 23, and 16%, re

Abstract:

Pine stands affected by root and butt rot (Heterobasidion annosum s.l.) contain pines (Pinus sylvestris L.) that can survive for a long time without showing external symptoms of the disease (‘conditionally resistant’ refers to trees that survive without symptoms despite infection). The establishment of stands from the seeds of such trees can significantly increase the effectiveness of artificial afforestation. Since the growth and development of pine trees is determined to a certain extent by the number of cotyledons after seed germination, this article examines this trait in the progeny of tr
