The study was carried out at the Deštné field research station in the Orlické hory Mts. (altitude 900 m, WSW aspect) in winter seasons 2005/2006, 2006/2007 and 2007/2008. The process of snow accumulation and melting was markedly affected or disturbed by the nearly total damage to the spruce stand by top breakage due to the extreme load of wet snow. Winter 2005/2006 was characterized by extreme parameters of snowpack (maximum depth of snow in spruce 157 cm, in beech 164 cm, maximum snow water equivalent in spruce 819 mm, in beech 833 mm). From the aspect of the snow cover duration, winter 2006/2007 was below the average, winter 2007/2008 was average. With respect to the significant reduction of the spruce crown biomass after snow breakage in winter 2005/2006, no significant differences were noted either in snow depth or in snow water equivalent in the spruce and beech stands. The rate of snow melting in the spruce and beech stands was never higher than 50 mm per day. If the spring final stage of snow melting is not accompanied by intensive rainstorms, mountain coniferous and broadleaved forest ecosystems reduce the danger of stormflows and floods within the required degree.

Landa Author-Workplace-Name: Prague, Czech Republic Title: Comparison of mycobiota of diverse aged spruce stands on former agricultural soil Abstract: The mycological conditions on study plots established in forests growing on former agricultural farm lands were studied. In young spruce stand (8-10 years) reduced and unstable spectrum of macromycetes was found. After approximately 50 years of forest growth the situation became stable and spectrum of macromycetes together with development of mycorrhizal status were similar to a situation found in stands on forest soils. Slightly increased occurrence of saproparasitic species of fungi (e.g. Heterobasidion annosum at others) was observed in older growths.

Abstract: The diversity of arbuscular mycorrhizal (AM) fungi of Acacia catechu Willd. was studied. Dominant AM spores, the bacterium Rhizobium sp. along with the fungus Trichoderma viride were isolated from the rhizosphere of A. catechu and mass-produced in laboratory. The co-inoculation effect of Glomus mosseae, Glomus fasciculatum, mixed AM (Glomus spp. [except G. mosseae, G. fasciculatum] with Acaulospora spp., Sclerocystis spp. and Gigaspora spp.), Rhizobium sp. and Trichoderma viride was studied as exerted on the growth of A. catechu seedlings. All inoculated seedlings showed improved seedling growth compared to the control. Inoculated seedlings had a pronounced effect on all growth parameters such as height, fresh and dry weight of roots and shoots, AM spore count, per cent mycorrhizal colonization in roots and root nodule number in comparison with uninoculated seedlings. Phosphorus uptake was also higher in inoculated seedlings than in the control. This study provides a good scope for commercially utilizing the efficient strains of AM fungi for beneficial effects with other beneficial rhizosphere microflora in the primary establishment of slow growing seedlings ensuring better survival and improved growth.

Moench plantation on an acidified mountain site Abstract: A young speckled alder (Alnus incana [L.] Moench) stand was planted on a tract clear-felled due to air pollution and located on a summit plateau of the Jizerské hory Mts. (Central Europe, Czech Republic) at an altitude of 950 m a.s.l. The aim of the experiment was to test the suitability of Alnus incana to form preparatory stands covering the site and thus enabling the reintroduction of more sensitive target species. A potential of Alnus incana to respond to slow-release fertilizing was tested as well. The control treatment showed sufficient growth dynamics, nevertheless, the fertilization significantly promoted the growth (documented by height, height increment and stem-base diameter). If some limitations of alder such as high light requirements are respected, the speckled alder can be recommended as a suitable species for preparatory stands even in the 7th and 8th altitudinal (vegetation) zones, especially when fertilized.

Under these conditions the nonesuch, highly cultural and ecologically valuable landscape complex has come into being. The tertiary road system is a part of this landscape and was built as one of its secondary structures. Forest and rural road systems were designed for higher efficiency of management and better utilization of land with 73% increase in hauling road density and 16% increase in rural cart-road density in the period under consideration. On the basis of evaluation of forest and rural road network development, evaluation of forest conditions and forest management the analysis of tertiary road development and forest management in this area can be made. Finally it is possible to draw up general methodology and principles of forest opening-up in respect of sustainable development. This methodology and principles in combination with design principles of rural roads and in accordance with functionally integrated management could be applied in the landscape management of this area and also in similar ones.
