The paper evaluates snow accumulation and the intensity of snow melting in a young spruce and beech stand. 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 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.

J. For. Sci., 2009, 55(10):461-468 | DOI: 10.17221/120/2008-JFS  

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...

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...

Development of tertiary roads in the Lednice-Valtice Cultural Landscape

J. For. Sci., 2009, 55(10):477-483 | DOI: 10.17221/93/2008-JFS  

The Lednice-Valtice Cultural Landscape is an exemplary area that has been influenced by purposeful human activity for a long time. 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,...
