A trial of "sour" felling to prevent bluestain by depletion of sapwood nutrients
2001 - IRG/WP 01-10404
Discoloration of conifer wood caused by bluestain causes large economic losses in Canada. Most deep stain develops in the log stage during storage or transport. In a search for control strategies that will not disrupt woodlands productivity we tested "sour" felling, termed "hagarashi" in Japan. The practice involves delaying the delimbing of freshly harvested trees. The tree continues to transpire...

Effect of felling time related to lunar calendar on the durability of wood and bamboo
-Fungal degradation during above ground exposure test for 2 years- (Preliminary report)
2005 - IRG/WP 05-20311
Current study was carried out to know whether the felling time of trees and bamboos based on lunar calendar affects natural durability of felled wood-bamboo or not. Each of one sugi (Cryptomeria japonica) tree of 28 years old and one Moso bamboo (Phyllostachys heterocycla) of around 3 years old was cut 12 times between February and December in 2003. Six sets of sugi tree and bamboo were felled in ...

The effect of felling time of year on CCA fixation rate and quality of selected hardwoods
1998 - IRG/WP 98-40116
White birch (Betula papyrifera), poplar (Populus sp.) and red maple (Acer rubrum) trees were harvested in winter, in spring, before the leaves flushed, after leaf flush and later in the summer. Sapwood discs were cut from the freshly felled trees, dried and cut into 25 mm and 19 mm cubes. The cubes were pressure impregnated with CCA-C and fixed under high relative humidity and at 50°C or at room ...

Influence of felling time on the natural durability of norway spruce (Picea abies (L.) Karst.)
1998 - IRG/WP 98-10250
Natural durability was tested in a laboratory test according to EN 113. The test fungi were Coniophora puteana and Poria placenta. Additionally, the test method was modified by using water agar instead of malt agar, so that wood was the only nutrient source for the fungi. In a third attempt the samples were inoculated with Trichoderma harzianum before testing.
The trees were felled on the 22.7.97...

Preservation of coppice wood for the fabrication of glued beams or panels
1987 - IRG/WP 3427
In this survey we will examine the specific problems concerning the conservation and the preservation of timber (issued from trunks of small diameter corresponding to products of clearings or coppices) destined for the fabrication of solid reconstituted elements. Thus for six metropolitan species of wood, we first characterized the biological deteriorations which occur after felling and their kine...

An analysis of the effects of some factors on the natural durability of pine (Pinus sylvestris L.) and spruce (Picea abies Karst.)
1986 - IRG/WP 1279
The effects of some factors on the natural resistance of pine and spruce sapwood against fungal decay and against attack of house-longhorn beetle larvae have been studied in laboratory tests and the results are evaluated by analysis of variance and regression analysis. Following conclusions were reached: Wood from summer-felled trees did not have a lower inherent natural durability against fungal ...

Chapter 5 - Nursing of bamboo
2007 - IRG/WP 07-10635-05
In this chapter various procedures and steps of nursing of
bamboo have been described with introduction, methodologies,
examples and photographs. The propagation, improvement and
sustainable growth of bamboo are possible through proper
nursing of bamboo. The nursing of bamboo includes proper
felling or extraction, fertilization and earth filling, protection
from diseases and injuries, silvic...

The influence of climate changes on Central European forests with an emphasis on Slovenia
2022 - IRG/WP 22-50368
When forests are managed sustainably, they play an essential role in protecting climate and biodiversity. They protect soils and water resources, provide livelihoods, and contribute to the well-being of rural and urban communities. European forests are multifunctional and provide a range of ecosystem services. These include the production of renewable materials that can replace materials with a la...
