The reflection of soil properties in the health condition of forest stands is connected with synergy of stressors that influence the forest existence. In the Krušné hory Mts. (Czech Republic, Europe) methods of full-area site mechanized preparation before reforestation were applied on existing ecotopes of the air polluted clear-cut area and the uniform relief of windrows was established. The hypothesis whether the soil in the windrows could be directly used for local cultivations as a substrate suitable for forest tree species growth was examined. The influence of three machines (digger, bulldozer and cultivator) used for the windrow cultivation was...

Several methods of Pristiphora abietina adults catching were compared (Malaise trap, white and yellow sticky boards, sweeping). The yellow sticky boards are handy in the field, and under the high population density appear to be a reliable method of detecting sawfly populations: 1. There was a statistically significant coincidence between the samples of Malaise traps and yellow sticky boards. 2. There was a highly significant linear correlation between the number of caught adults on five sticky boards and the degree of defoliation in seven localities. 3. We did not observe any statistically significant differences between the samples on yellow...

The paper deals with the occurrence of fungi and rusts, viruses and insects on main woody species in riparian stands along the middle courses of the Slatina and Hron rivers in Slovakiain 2002-2004. Forty fungal species, rusts and viruses and 79 insect species were found. The highest number of fungi occurred on the branches and twigs of poplar where Cryptodiaporthe populea (Sacc.) Butin and Phellinus igniarius (L.) Quél. had the highest representation and so the influence on the health condition. Melampsora alliipopulina Kleb., Poplar mosaic carlavirus, Venturia po-pulina (Vuill.) Fabr. and Venturia tremulae...

Dothistroma needle blight Mycosphaerella pini E. Rostrup and its anamorphic stage Dothistroma septospora (Dorog.) Morelet was detected for the first time in the territory of the Czech Republic in a consignment of imported plants of Austrian pine Pinus nigra Arnold in 1999. In 2000, it was also found on Pinus nigra in an open planting in a plantation of Christmas trees by the village of Jedovnice near Brno in South Moravia. In the Czech Republic, Dothi-stroma needle blight was identified on 13 species of pine. Pinus nigra Arnold and Pinus mugo Turra are the most frequent hosts. In addition to these...
Spontaneous infiltration of broadleaved species into a spruce monoculture left without tending

An experimental stand was established as a monoculture by planting Norway spruce on a clear-felled area in 1925. In 1958, a research thinning experiment was established there. Control plots and the study of their development without anthropic interventions are of interest in particular. The spruce monoculture nearly disintegrated and the stand-forming role was taken over by species which occurred there originally as admixed ones. The stand became sparser and it was associated with the spontaneous regeneration of broadleaves. Out of the eight control plots three plots were selected differing significantly in stocking and extent of natural regeneration....

Dokumenty týkajúce sa regulácie hospodárenia v lesoch sa prakticky až dodnes považovali za materiály, týkajúce sa skoro výlučne len jednotlivých odborných rezortov. Na základe Vyhlášky Ministerstva financií SR č. 465/1991 ich možno efektívne využívať aj v rámci rezortov financií a spravodlivosti. Ďalšie významné medzirezortné využitie týchto dokumentov vyplýva zo Zákona č. 127/1994 o posudzovaní environmentálneho dopadu. Cieľom práce je demonštrovať proces posudzovania na konkrétnom príklade - ploche patriacej do lesného pozemkového fondu. Okrem máp, výsledkov pozorovania, slovných popisov a súborov numerických údajov, týkajúcich sa jednotlivých porastov,...
