Rchb., were established. In G. verna, the induction of organogenesis on vegetative shoots was successful on the basal 6% agar WPM medium with 200 mg.l-1of glutamine, 200 mg.l-1 of casein hydrolysate, 30 g.l-1 of sucrose, 0.2 mg.l-1 of BAP, and 0.1 mg.l-1 of IBA. The multiplication of primary explants was achieved on 6% agar basal MS medium with the same concentrations of substances mentioned above. In J. cyanoides, the induction of organogenesis and multiplication of its vegetative shoots were successful on MS medium with the same concentration of added substances used in G. verna. On the basal MS medium of 1/3 concentration with 3 mg.l-1 of IBA 70-75% rooting efficiency of G. verna microcuttings and 40% rooting efficiency of J. cyanoides microcuttings were reached. The mortality during acclimatization did not exceed 20% for G. verna and 25% for J. cyanoides.

In 2010, 15 TPTs and 15 TRIPODs were deployed (with a 10-m spacing) in a forest in the northeastern Czech Republic. The TPTs and TRIPODs were inspected weekly during the entire period of I. typographus flight activity (30 April-1 October). The TRIPODs were sprayed with Vaztak 10 SC insecticide every 7 weeks; at each spraying, the pheromone evaporators were renewed. Higher numbers of entomophagous arthropods, including the predacious beetles Thanasimus formicarius and T. femoralis, were captured by the TRIPODs than by the TPTs. The number of Thanasimus spp. captured by TRIPODs was especially high at the end of April. The efficacy of TRIPODs for the control of I. typographus could be maintained while the kill of nontarget organisms could be reduced by deploying the evaporators 1 week later (in early May rather than in late April) in relation to the recommended date of dispenser installation.

Abstract: The aim of this study is to identify a period of time over which smaller, less costly tree transplants can reach the height of larger tree transplants and thus offset their performance. The following Central European native tree species were used: Quercus robur L., Carpinus betulus L., Fraxinus excelsior L., Acer campestre L., Acer pseudoplatanus L., Tilia cordata Mill. and Prunus avium L. In the period after planting, the best growth was observed for small tree transplants. These transplants reached the height of the medium-sized tree transplants for all species except C. betulus. However, the large transplants of A. campestre, F. excelsior and P. avium were still significantly taller than the medium-sized transplants ten years after planting. In contrast, slow growth was observed for the large tree transplants of C. betulus and Q. robur. During the monitoring period, the height of the medium-sized transplants of C. betulus even exceeded the height of the large transplants of this species. These differences suggest that the differences in the establishment rates of individual species are reflected in the growth rates of their plantations during longer periods after planting.

This shortcut would greatly enhance our examination of the gene flow and population structure of trees in diverse tropical rainforests. To explore the effectiveness and limitations of this approach, we examined allelic diversity at six microsatellite loci, originally developed in a congeneric species, in three populations of Shorea platyclados from Peninsular Malaysia. Fragment sizing was performed by an efficient and sensitive (1 bp resolution) technique using capillary electrophoresis, ethidium bromide detection, and minimal clean-up. Fragment size ranges were conserved between species and null allele frequencies were low. Higher overall levels of genetic diversity were detected in our study. Variation among populations was directly related to geographic distance. Fragment size class distributions suggest that each locus should be studied using different evolutionary models. Direct sequencing of SSR fragments revealed that size differences were due to changes in both the flanking regions and repeat motifs. Several clear examples of size homoplasy were observed, along with the disruption of perfect repeats, suggesting that cross-specific amplification of microsatellite loci requires an additional level of confirmation at the DNA sequence level before the influence of size homoplasy and changes in repeat structure can be assessed. Simulation studies demonstrate that the increasing intensity of timber harvest leads to higher variability in levels of potential heterozygosity and decreasing total number of alleles in the remnant "mother trees" The careful selection of "mother" trees can greatly enhance the future genetic diversity of populations.

We assessed the effects of ground-based skidding on site disturbance and soil physical properties. We also tested the effects of skid trail slope and traffic frequency on soil compaction, total porosity, and moisture content. On average, about 30% of all harvested area was disturbed to varying levels. Intact forest floor (undisturbed) and light slash were the dominant surface conditions, covering an average of 68.9% of harvested area. Deep disturbed soils accounted for only just over 1.1% of observations. Results showed that dry bulk density, total porosity and moisture content were affected considerably on skid trails by traffic frequency and skid trail slope. Measurements of soil properties in the surface layer (0-10 cm) showed that bulk density is 57% higher and total porosity is 31% lower on the skid trail compared to the undisturbed area. Average moisture content has been measured as 35% on the skid trail versus 47% in the undisturbed area.

Abstract: We have verified whether the temperatures in the zone of terminal leaders of saplings (+100 cm) were less extreme than the temperatures in the zone of terminal leaders of common-sized planting stock (+30 cm). In May and June of 2011 and 2012 we investigated the occurrence of late frosts at different levels above the ground. The number of days and amount of hourly frost records were counted and the sum of sub-zero temperatures was calculated. Our study confirmed that sub-zero temperatures mostly occur at levels near the ground. Therefore, on the sites exposed to late frosts, such as mountain frost hollows, in addition to common-sized planting stock we recommend to consider also the use of large-sized transplants (saplings), since their terminal buds are mostly above the zone near the ground most endangered by frost.

These forests play an important role especially in a mountain landscape. Forests decrease peak flood flows, compensate water discharge and represent a source of high-quality fresh water. The optimum hydrological function is provided by forests that are healthy, ecologically stable, diversified, proper to site, growing on a good forest soil, managed by small-area felling and emulating natural processes. For mountain sites of the CR, the optimum proportion of Norway spruce (+ Silver fir) ranges from 70 to 80% and of European beech from 20 to 30%. Clear-cuts due to air pollution disasters led to replacement of the forest stand by perennial grassland increasing stormflows and decreasing the soil water supply to groundwater resources and the quality of water discharged from the forest. Skidding and hauling operations and an improperly constructed and maintained road network increased the surface runoff from a forest. Intraskeletal erosion occurs on pollution-disaster stone fields and in dying forest stands on stony sites. Reforestation of stone fields is necessary for the preservation of forests on stony and bouldery localities and their services for the cultural landscape situated below. In mountain headwaters, torrent control and forest amelioration are of great importance. These decrease peak flood flows, compensate water discharge and reduce bed-load and sediment transport. Forest amelioration enables the reforestation of waterlogged pollution-disaster areas.
