    Opis:
    The corridor method of oak (Quercus sp) cultivation is an old, forgotten silvicultural method. It was developed around the turn of the 19th and 20th century on the south-eastern borders of Poland (Podole, Wołyń) and Russia and made use of other species such as hornbeam, linden and birch as a cover for oak, which is a tree species sensitive to frosts. The nowadays recurring phenomenon of oak disease initiated a search for silvicultural alternatives and thus the usefulness of reviving the corridor method for oak regeneration was investigated by examining existing tree stands established in this way. Our research plots were located in five young stands and two in mature as well as old stands. In the stands of the 2nd and 3rd age classes, the density of oaks was observed to be 1500 - 3500 /ha, which accounted for 30-50%. The density of oak in old stands (7th age class) was similar to model-predicted values. Furthermore, the corridor method gave very good production results as exemplified by the oak stands growing on the fresh broadleaved site, which had a very high stand quality index. In addition, the species composition was observed to diversify throughout these oak stands’ development, thus supporting arguments for the conservation and preservation of oak-hornbeam forests. To summarise, the prerequisites for the success of the corridor method are systematic cuts of young stands (forest cultures and thickets) to inhibit the growth of accompanying undesired species and limiting the number of grazing animals.

    Opis:
    The aim of this study was to verify descriptions of the morphology of the fungus responsible for powdery mildew on oak leaves of nursery seedlings and of young trees in forest stands. Infected, fully developed leaves from apical parts of stems of Quercus robur or Q. petraea were collected in two national parks and in six forest districts in Poland. The taxonomic characteres of all specimens were generally consistent with those given in keys for Microsphaera alphitoides. However, the limoniform shape of conidia, characteristic of two sites (nurseries), has not been found in available synopses. Limoniform conidia were significantly longer and wider than others. Agreat variety of forms of mycelium on leaves were observed. The mycelium appeared in three forms: (1) floccose or felted oval patches (always with yellow or brown discoloration), (2) faveolate oval patches (often with yellow or brown discoloration), and (3) felted or mealy mycelium along veins (rarely with discoloration). Mycelium without limoniform conidia appeared in all forms, while mycelium with limoniform conidia appeared only in the form of patches, always causing leaf discoloration.

    Opis:
    The ability of spatial expansion and conquering of new locations, suitable for growth, is one of the most important properties enabling different plant species (including forest trees) a permanent existence in a constantly changing (in space and in time) environment. In the course of evolution, plants developed several adaptations and mechanisms enabling them to capture new localities appropriate for life. The key role in this process is played by so called propagules, i.e. differently built spores, seeds and fruits. The main sources of forces and major transportation vectors for propagules are such mechanisms as: power of gravity (barochory), wind (anemochory), water (hydrochory), animals (zoochory) and man (antropochory). Among them, in case of tree species producing large seeds, containing bulky amounts of food resources, the most important role is played by zoochory. The special variant of zoochory is ornitochory, i.e. dispersion of plant propagules by birds. One of the best known and documented examples of ornitochory is dispersal of oak acorns by jays (Garrulus glandarius). The contemporary research shows that during a vegetation period one single bird is able to deposit even several thousends of acorns within the area of 10 to 100 ha. The dispersal distance in case of acorns distributed by jays is variable and depends on several factors, first of all, climatic conditions and degree of environmental heterogeneity. On average, acorns are distributed within a distance of several hundred meters from seed trees; sometimes they are disseminated at a distance of several (4−8, maximum 20) kilometers. As a rule, only a part of deposited acorns is uncovered and consumed by birds, thus at least some of them can germinate and produce new oak seedlings. It was also recently demonstrated that jays preferably put down acorns under the stand canopies composed by tree species other than oak, for instance, under Scots pine trees. Under favourable conditions, this initiates natural successional processes and leads to a significant conversion of tree stand composition. Considering a large scale and commonness of this phenomenon, it deserves an interest and attention, not in the case of natural forests only, but in the case of managed forests as well, in which the quasi−natural, successional processes, initiated by jays, can considerably contribute to a greater compositional and structural diversity of tree stands.

    The paper provides an analysis of changes in coefficients of variation of basal area and merchantable volume sums on sample plots of various sizes 1, 2, 4, 10, 6, 25 and 50 ares in a two−storey stand (storey I – pine 195 years, storey II − oak 105 years) over the last decade. The authors established how many times the number of sample plots of a given size at a given age should be increased in relation to the last measurement to attain the same result accuracy. Moreover, the optimal size of small sample plots that can grant the most accurate results was calculated.

    Opis:
    Stand characteristics were analysed for the occurrence of regrowth with a species matching the dominant species of a stand. The analysis covered: stand age, stocking, degree of shelter (the sum of stocking plus the percentage of the shrub layer cover), dbh basal area, type and the dominant species of the vegetation cover. The obtained results were considered as preliminary criteria of the maturity age for regeneration.

    Opis:
    Permanently balanced forest economy demands today a resignation from a constant model of the forest stand, which preferred the productive function of the forest, mostly without any consideration to its natural values formed by Mother Nature. Implanting on Polish grounds principles of multifunctional forest districts acknowledged as a breeding object of the whole forest ecosystem, giving in that way the forest economy a proecological dimension. Its a result from a general progress of civilization and achievements in forest science; reaching towards the needs and expectations from the society gaining a general acceptation from different environments. One of the fundamental elements implementing the ecosystem is to rebuild deformed and artificially barred forest phytocenosis. This refers especially to pure pine stands on habitats, in which trophoism potential explains breeding habitats species variety. A good help for the forester in this area can be a natural succesion of good, noble broad−leaved species like for example the oak. Succesion of this species takes on a special meaning in poor habitats, in which it without any special imposes enriches the biocenose with the whole positive outcome accompanying this process; it can also be a valuable clue to the potential fertility in the habitat and the complexity in the forest vegetation community. An important task is to lead the way for the oaks development from succesion to its fullest use as a natural presence in creating the future forest generation. The article below is devoted to this question describing the natural up growth of the oak in pine stands on the coniferous forest habitats in Forest District Różanna and the methods and results in which they are used for breeding.
