obtained from accounting reports and statistics of some
working-plan areas, affiliated forest enterprises (OLZ)
and state forest enterprises. The analysis was made down
to the level of concrete records of tasks, namely 6,855
for felling, 8,032 for skidding and 3,098 for timber handling.
Selection of concrete working-plan areas was made
with regard to the distribution of spruce, the proportion
of spruce in selected working-plan area being higher than
50%. According to affiliated forest enterprises the following
working-plan areas were included:
– OLZ Èierny Balog – Šaling, Osrblie, Hronec, Dobroè,
È. Balog, and Sihla,
– OLZ Beòuš – Polomka, Pohorelá, È. Skala, Beòuš,
Švermovo and Závadka,
– OLZ Námestovo – Zubrohlava, Trstená, Oravice, Or.
Polhora, Námestovo and Habovka,
– OLZ Oravský Podzámok – Zákamenné, Párnica,
Paráè, Or. Podzámok, Lokca and D. Kubín.
Arithmetical means of cost coefficients were calculated
on the basis of data from these working-plan areas
and affiliated forest enterprises. Wage tariffs were derived
from higher collective agreements. The costs for
the years 1988 and 1991 are taken from HALAJ et al.
(1990) and PETRÁŠ et al. (1992).
RESULTS
TIMBER PRICES
We can see from average realized timber prices in
SKK/m 3 in Table 1 that timber prices have increased for
all quality and diameter classes. The only exceptions are
quality classes V and VI, it means pulpwood and fuelwood,
in which their prices did not change in some years
or they slightly dropped. Regarding the coefficients of
variation presented in Table 1 for each average price, we
can state that unit prices varied a lot between forest enterprises.
Coefficients of variation ranged from 2 to 10%
for most assortments and calendar years. If we compare
their values between calendar years we can state that the
