“…Human activities are known to be the most important factors predisposing stands to butt rot, and the increased risk due to cuttings should be included in models for predicting the probability of butt rot in spruce (Möykkynen et al 2000). In our study, however, customary thinnings did not explain the risk of butt rot.…”

“…These models have been used in stand-level analyses of the incidence and severity of damage, the effects of thinnings on damage or the benefits of controlling the disease (Greig and Low 1975, Stenlid 1987, Pratt et al 1989, Möykkynen et al 1998). In addition, in Denmark and Sweden empirical models have been developed to predict the incidence of butt rot (Vollbrecht andAgestam 1995, Vollbrecht andBilde Jorgensen 1995).…”

The aim of this study was to analyze the occurrence of butt rot damage to Norway spruce in different parts of southern Finland and to quantify the associated loss of quality. The data used in the study are from the 9th National Forest Inventory and consist of 5998 sample plots and 8007 spruce sample trees of saw-timber size. To predict the probability of damage to stands and trees, logistic regression models were constructed. Separate models were made for the whole study area, for the area where the general risk of Heterobasidion root and butt rot damage is high and for the area where the damage frequency is relatively low. In the highrisk area, the probability of damage decreased with increasing elevation and increased with increasing temperature sum. In addition, damage was more common on fertile sites and less common on peatlands; and thick peat layer decreased the risk of damage. The probability of damage was also higher in stands where special or selective cuttings had been carried out. In the sample tree data, the probability of damage increased slightly with increasing diameter and age of the tree. In the low-risk areas, elevation was the only variable that explained the probability of damage to a spruce tree. Site fertility and previous cuttings (more than ten years ago) explained the probability of damage to stands only weakly. For spruce damaged by butt rot, the saw-timber volume was reduced, on average, by 60% both in the high-risk area and in the low-risk area.

“…The ambitions of the current researchers deal with the transformation of the present expertise in simulation models to describe the spread of the pathogen throughout the stand (Frankel et al, 1994;Vollbrecht and Jørgensen, 1995;Pratt et al, 1998;Möykkynen et al, 1998Möykkynen et al, , 2000Müller, 2002;Pukkala et al, 2005) with the objective to calculate losses and adequate treatment scenarios. The combination of the simulation models with existing forest growth models was a necessary step to support the decisions made on the forest management level.…”

Heterobasidion spp. root rot causes severe damage to forests throughout the northern temperate zone. In order to prevent Heterobasidion infection in summertime cuttings, stumps can be treated with urea or Phlebiopsis gigantea. In this study, the consumption of stump treatment materials and the quality of stump treatment work were investigated. A total of 46 harvesters were examined in May-November 2016 in Finland. The average stem size of softwood removal and softwood removal per hectare explained the consumption of stump treatment material. The quality of stump treatment work was good in the study. The best coverage was achieved with the stumps of 20-39 cm diameter at stump height (d 0 ). It can be recommended that the harvester operator self-monitors and actively controls his/her treatment result in cutting work and sets the stump treatment equipment in a harvester if needed. The results also suggested that when cutting mostly small-and medium-diameter (d 0 ≤ 39 cm) conifers, the stump treatment guide bars with relatively few (<18) open holes are used, and at the harvesting sites of large-diameter trees, the guide bars with a relatively great (>27) number of open holes are applied.
