The objectives of this study are to determine the progress of the development cycle of the forest taking into account untypical development periods caused by fir decline and recovery, and to compare the per cent participation of individual phases and periods of forest development in the ¦więta Katarzyna and ¦więty Krzyż Forest Ranges of the ¦więtokrzyski National Park. The development stages, phases, and periods was determined in P6 fields of the SINUS System of Information on Natural Environment. Tree age distribution, stand structure, volume increment tendency (an increasing or decreasing one), and also the radial increment of fir and...

In 2002, height and diameter growth of spruce was investigated in the Orlické hory Mts. (the Czech Republic). The aim was to confirm and to quantify a growth increase in stands of different age, and to reveal the relation between growth and climate, and level of nitrogen deposition. Stem analyses of ten sample trees of mature spruce stand (average age 163 years) confirmed a significant increase in height and diameter growth since the mid-eighties of the 20th century. Nearly 75% of radial increment variability could be explained by climatic factors. Growth in the last 10 years corresponded well to weather conditions. Analysis of the growth...

The article is devoted to problems of forestry financing in the Czech Republic in the period of transition to market economy (1991-1999). The policy of forestry financing is aimed above all at the provision and improvement of quality of sustainable non-market forest goods and services. Thirty programmes and 46 sub-programmes were analysed in the CR in 1991-1999. The level of financial support ranged from 909.4 mil. CZK to 1,501.7 CZK with the exception of 2,540.1 mil. CZK in 1991 (all in stable 1999 prices). On average, the support amounted to about 10% of the GDP created by the forestry sector in the given period.

The paper summarizes results of an institutional research aimed at the evaluation of the effect of a coating system on the rate of plywood moistening and changes in dimensions in relation to changes in relative air humidity. Coefficients of dimensional changes were determined in relation to relative air humidity and effects were studied of the coating system on the rate of plywood moistening. All measurements were carried out in water-resistant combined plywood with surface coating and thickness of 8, 10, 12, 15 and 18 mm and in all-beech plywood 10, 12, 15 and 18 mm in thickness. Based on the results obtained it is possible to state that bending strength...
