Determination of some Physical and Mechanical Properties and quality of Demeged Fir (Abies Alba Mill.) Trees     pdf     HR     EN 391
Summary: Since 1950, when it was first observed in their native areal,
the dying of fir forests has been on the increase. It has been confirmed by
observing the percentage of the growing-stock increment. In the Zalesina
forests management unit Kupjački Vrh, the increment percentage was 1.9%
in 1951/52; in 1994/95 it fell to 0.62%. Owing to the significance of the
phenomenon, in 1968 started a research project on the fir and oak forest
dieback. The so far accomplished work has revealed the complex interactions
of climatological, ecological, pedological, biological and antropogeneous
factors influencing the fir forests. The last blow to the physiologically weakened
trees was given by bark-beetles.

The aim of this paper is to establish the probable links between the
reductions of the fir crown assimilation system with the change of the physical
and mechanical properties of wood.

Three fir trees with the degrees of damage 0, 1 and 3 were chosen
according to the criteria of the European Community Forestry Commission.
Test samples were taken for establishing the physical and mechanical
properties according to the valid standards.

The research reveals that the established values of the physical and
mechanical properties do not correspond to the damage degree of the fir crown.
Neither has been established the expected fall of the analyzed properties as
shown on the outer annual rings of the dmaged trees. The conclusion was
that the damage of the fir crowns has not made an impact on the physical and
mechanical properties of the wood. The quality and practical use value of the
firwood have not been affected either. Colour change of the sawmill logs did
not affect the quality classification.
