The parameters of site conditions included type of forest operations, stand age, site productivity, ground slope and forwarding distance. The correlation ratio between each parameter and machine utilisation was low and not significant at a significance level of 0.05. Harvester's utilisation rate varied from 48.6% to 100.3% while it averaged at 77.3%. Forwarder's utilisation in this case varied from 47.8% to 96.5%. The average rate for forwarder in this study was 81.1%. The long-term machine utilisation rates can be applied by the operation management to control the current level of machine utilisation and to calculate the machine hourly cost accurately to obtain unit harvesting costs.

The aim of this paper is to evaluate the partial results of the research from 2013 and 2014 which was focused on the economic assessment of the recreational potential of the TFE MF Křtiny. The busiest roads in the forest road network and bike trails located in the Bílovice nad Svitavou forest district were selected. The results can be used to assess the impact of the forest enterprise on the economic and social development of the area, to measure the attractiveness, quality and facilities offered in the forest.

The product Lexin (a mixture of humic acid, fulvic acid and auxin), which also supports seed germination, was selected as a reference treatment. The results show that the most effective is the lowest concentration of brassinosteroids which gave nearly the same effect as the reference product Lexin. The data also suggest the positive effect of pretreatment of sycamore and ash seed in pure water both on germination and germination energy.

A total area of 1,500 m2 (30 × 50 m) was covered in five altitudinal classes ranging from 800 to 1,800 m a.s.l. Samples were taken based on a systematic random sampling method with 24 sample plots at each class. In total, 120 sample plots (in five classes) were collected covering four gradient categories ranging from < 20 to > 60%. An analysis of variance (ANOVA) was carried out to compare differences between group means in gradient categories and Duncan's post-hoc test was performed to reveal differences between the means of various quantitative characteristics (e.g. growing stock, basal area, diameter at breast height, tree height and regeneration) and the altitudinal classes. The Kruskal-Wallis test was used to examine the differences between the means of qualitative variables and different altitudes and slopes categories. The results indicated that variations with altitudes may have a higher impact than slopes on the quantitative characteristics of the oak stands in the region while the qualitative variables of the native species were influenced by both altitudes and slope variations.

(Czech Republic). Differences in the occurrence of Chilopoda, Diplopoda and Isopoda on sites with spruce and beech were determined by F-test. Diplopoda and Isopoda preferred beech stands and Chilopoda spruce stands. The species Protracheoniscus politus (Koch) (Isopoda) indicated a positive relation to beech stands. Among Diplopoda, a strong linkage to beech was seen in Glomeris hexasticha (Brandt), while Julus scandinavius (Latzel), Hassea flavescens (Latzel) and Brachyiulus bagnalli (Curtis) tended to prefer the spruce forest environment. The highest variability was found in Chilopoda, of which the species dominating in beech stands are Cryptops parisi (Brölemann), Strigamia acuminata (Leach) and Strigamia transsilvanica (Verhoeff), while Geophilus flavus (DeGeer) and Geophilus insculptus (Attems) prevail in spruce stands. A wide spectrum of captured species of the order Lithobiomorpha differentiate in their relation to spruce [Lithobius forficatus (L.), L. cyrtopus Latzel, L. erythrocephalus C.L. Koch, L. tenebrosus Meinert, L. austriacus (Verhoeff), L. biunguiculatus (Loksa)] and beech [Lithobius microps (Meinert), L. mutabilis L. Koch, L. burzenlandicus Verhoeff, L. micropodus (Matic) and L. nodulipes Latzel]. Based on the findings, we can confirm increased incidence in beech forests, although the result is not unambiguous. Therefore, it is necessary to admit that the factor of the main tree species within a stand cannot be used as the single criterion and needs to be supplemented with additional conditions of the natural environment.

Due to different climatic and soil moisture conditions in the monitored years, different seasonal courses of stem increment formation were observed using band dendrometers with continuous data recording. The lack of precipitation affected growth processes mainly during the growth culmination and at the end of summer. The multiple regression analysis of the impact of individual factors on stem circumference changes on the basis of their partial correlation coefficients revealed that the individual environmental characteristics influenced daily stem radial changes with time lags of one to ten days. The results of the analysis of variance showed that the stem radial reactions to climatic and soil moisture factors were not significantly different between the clones.
