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 monitored in relation to soil properties. The state of the properties of prepared sites was compared with retained windrows and control plots with scarification. The effects of mechanized soil preparation before reforestation were different according to the concrete ecological factors of the given sites. The influences of individual means of mechanization on concrete soil properties were determined as locally differentiated. The windrow cultivation led to an increase in cation exchange capacity (CEC) especially due to an increase in Ca2+ and Mg2+ content. Locally it led to the stabilization of N-NH4 content. The optimization of soil physical properties was connected with the state of Cox. The mechanized windrow cultivation did not optimize either C/N ratio or maximum capillary capacity (ΘMCC) or porosity (p). The mechanized windrow cultivation in the conditions of decreased air pollution load generally appears as a good technology for revitalization of degraded sites because it provided more optimal trophic conditions for the forest tree species growth than windrows or sites with completed scarification.

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 sticky boards taken in different intervals. To estimate the abundance of adults, it is sufficient to install yellow sticky boards before swarming and check them after the swarming. 4. No statistically significant differences were found between the catch means per board in line with different number of boards, it means with different distance, in both male and females.

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 Aderh dominated on the leaves. The most frequently present fungus on the aspen was Armillaria sp., Phellinus igniarius (L.) Quél., on the alder a new hybrid from the genus Phytophthora - alder Phytophthora, Valsa oxystoma Rehm., Inonotus radiatus (Sowerby) P. Karst. and Inonotus obliquus (Fr.) Pilát. From the insect species Melasoma vigintipunctata Scop. and Phyllodecta vitellinae L. caused total defoliation on willows. The highest occurrence on the black poplar was on the leaf stalks represented by Pemphigus spirothecae Pass. species, on the alder it was Cryptorrhinchidius lapathi L. on the twigs and Agelastica alni L. on the leaves.

Rostrup - new hosts of Dothistroma needle blight observed in theCzech Republic Abstract: 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 species, Dothistroma needle blight was observed on Pinus ponderosa Douglas ex Lawson, Pinus jeffreyi Grev. et Balf, Pinus banksiana Lamb., Pinus contorta Douglas, Pinus rotundata Link, Pinus leucodermis Ant. and Pinus sylvestris L. Finds on Pinus aristata Engelm., Pinus rigida Mill., Pinus heldreichii H. Christ. and Pinus cembra L. var. sibirica (Du Tour) G. Don. are a certain rarity. These species are not mentioned anywhere as potential hosts of Dothistroma needle blight. As for the species of other genera Picea pungens Engelm., Picea abies L. Karst. and last but not least Picea schrenkiana Fisch. & C. A. Mey were also observed as hosts. The host range of Dothistroma needle blight recorded in papers is noted as well.

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. The development of regeneration was studied in detail on these plots. The undergrowth consisted of 24 woody species in a total number of 6,000 individuals per hectare and about two thirds of them belonged to trees. The results of the study show a possibility to convert a spruce monoculture to a broadleaved commercial forest using the spontaneous regeneration of trees.

Kundrík Author-Workplace-Name: Institute of Forest Ecology of the Slovak Academy of Sciences, Zvolen, Slovak Republic Title: Final documents of forest management regulation in the Slovak Republic and their possible interdepartmental use for environmental impact assessment Abstract: 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, obsahujú tieto dokumenty aj kódované údaje, ktoré pre väčšinu užívateľov nie sú zrozumiteľné bez využitia dekódovacích kľúčov. A práve tieto posledné údaje majú pri vyhodnocovaní environmentálneho dopadu najvyššiu výpovednú hodnotu. Po nadobudnutí platnosti pripravovaného zákona (vyhlášky) o strate vlastníctva, vyplývajúcej z prohibitívnych a ďalších podmienok v lesnom hospodárstve v súvislosti s presadzovaním verejno-prospešného záujmu (Kundrík et al. 1999), významne vzrastie dôležitosť využitia finálnych dokumentov týkajúcich sa regulácie hospodárenia v lesoch SR.
