    Opis:
    The objective of the study was to determine the size of interest in spending leisure time in forests among the residents of the Podkarpackie Province (south−eastern Poland) and to examine recreational potential of Rzeszów suburban forests. At first, basing on surveys, the demand for leisure in forests among the adult residents of the Podkarpackie Province was assessed. The survey was conducted on the random group of 439 people. Then, the recreational potential of the suburban forests of Rzeszów was assessed using own method. Almost 90% of respondents declared that they spend leisure time in forests. Most of the them rest in forests several times a year (54%), while only 9% respondents does it several times a week. The largest group among people spending their free time in forests is willing to travel up to 20 km to get to a forest. Forests suitable for recreational use cover nearly 56% of the analysed area, Among them 29% are tree stands of high or very high usability. The decrease in usability for recreational purposes predominantly results from the large share of wet habitats and dense understory. The recreational capacity calculated for Rzeszów suburban forests located within 20 km of city administrative limits amount to 1.79 man−hour/ha/day. The presented results indicate that every week 435,000 people may stay in the Podkarpackie Province forests, while approximately 43,000 – in Rzeszów suburban forests. The paper shows that there is a huge interest in spending leisure time in forests among the residents of the Podkarpackie Province, while the calculated recreational potential of Rzeszów suburban forests may be exceeded. Therefore a real risk exists that the forest environment will be damaged, moreover Rzeszów suburban forests are still poorly equipped with recreational facilities. A type of activity that counteracts this disturbing phenomenon is adequate management of recreational traffic and its balanced distribution over the areas that are naturally resistant to damages. It is also necessary to limit recreational utilisation of the forests where the calculated recreational capacity equals 0. Moreover, one should strive to boost recreational capacity of forests by their proper management.

    Opis:
    Woodpeckers are a very good indicators of forest naturalness. The fact that many species of these birds are in decline in central and western Europe resulted from changes in forest management (e.g. favouring coniferous forest, removal of dead trees). The aim of this research was to evaluate the importance of patches of deciduous species for the occurrence of some specialized woodpeckers in the conditions of Scots pine dominated stands. The study focused on species associated with deciduous forest, i.e. middle spotted woodpecker Leiopicus medius (L.), white−backed woodpecker Dendrocopos leucotos (Bechstein) and grey−headed woodpecker Picus canus (Gmelin). Statistical analyses were performed for the woodpeckers, which occurred in more than 10 territories. The studies were performed in 2015−2017 in the southern part of the Sandomierz Basin in three study areas (52,6−59 km²). Two plots were dominated by black alder Alnus glutinosa and oak Quercus sp., while the third one was characterized by the highest share of black alder, followed by silver birch Betula pendula and oak. Deciduous trees at the age over 80 years accounted for less than 2% of the total area of each plot. The most abundant bird species in patches of deciduous forest was the middle spotted woodpecker (25 territories), while the rarest was white−backed woodpecker (1 territory). Grey−headed woodpecker appeared in 12 territories. The density of woodpeckers in deciduous forest areas ranged from 0.45 territories/100 ha for grey−headed woodpecker to 1.54 territories/100 ha for the middle spotted woodpecker. In the alder patches we found all territories of grey−headed woodpecker, 24% territories of the middle spotted woodpecker and single territories of white−backed woodpecker. The patches dominated by oak accounted for about 76% of territories of middle spotted woodpecker. The average area of the patches with presence of middle spotted woodpecker and grey woodpecker was significantly higher than the patches where woodpeckers were absent. The middle spotted woodpecker occurred in the forest patches with the highest average age. Redundancy Analysis (RDA) demonstrated that the occurrence of middle spotted woodpecker was most strongly associated with the area of the patches over 10 ha, while the grey−headed woodpecker preferred mature forest stands of alder. These species abundance was negatively correlated with a patch area less than 10 ha.

    Opis:
    European beech is one of the most important broadleaved tree species in Poland and will play probably even more significant role in the future due to the predicted climate change. The main objectives of this study was to analyse and compare the growth parameters and morphological traits between 23 European beech provenances from south−eastern Poland (fig. 1). The research was conducted on the experimental plot established in Łosie Forest District in 2006. The experiment employed a randomized complete block design consisting of 92 plots (23 provenances×4 blocks). On each plot 100 trees representing given provenance were planted in 1.5×1.5 m spacing. In the spring and autumn 2015 we measured and determined the following parameters for the subsample of 36 trees on each plot: survival rate, tree height, diameter at breast height, diameter of the branch at the middle height of the crown length, stem straightness, crown shape, tendency to create forks, mean angle between stem and branches and spring phenology. We also included different eco−physiographical characteristics for each provenances (tab. 1). We performed basic statistics to describe mean values and standard errors (fig. 2, tab. 2) and finally we quantified the interaction between traits and eco−physiographical characteristics by Principal Component Analysis (PCA) (fig 3, tab. 3). The obtained results indicates that under growth conditions on experimental trial in Łosie Forest District, the provenances from lower elevated regions with lower precipitation and higher mean temperature (i.e. more arid conditions; Kielce and Narol provenances) were characterized by thicker dbh and branch dimeters in contrast to regions from southern Poland (Łosie, Bricza 1, Stary Sącz and Nawojowa). European beech provenances from regions with more humid conditions and lower mean annual temperature, as well as shorter vegetation season are characterized by higher survival rate. They are also higher than other provenances, but reveal the lower ratio dbh to branch diameter.

    Opis:
    In the Kolbuszowa Plateau forest areas, aggregations of brambles were observed most often in young forest plantations and forest clear cuts. In the 20 plantations that we examined, 11 bramble species were found. The most common bramble species in young forest plantations were Rubus plicatus, R. nessensis, R. hirtus, R. idaeus and more rarely R. gracilis, R. ambrosius and R. apricus. The largest bramble aggregations occurred in plantations located in mixed pine-oak forests, subcontinental lime-oakhornbeam forests and drained black alder forests. In young forest plantations the Rubus species were accompanied by species characteristic for the Vaccinio-Piceetea, Querco-Fagetea, Epilobietea angustifolii, Molinio-Arrhenatheretea and Nardo-Callunetea associations. There are three groups of bramble species which occur in young forest plantations: I – species with thin, prostrate and rooting stems (R. hirtus, R. apricus, R. pedemontanus), the negative impact of which on tree seedlings could have been very significant if the bramble specimens or diaspores had been present at the moment of tree planting; II – species with strong, poorly branched and arched stems (R. plicatus, R. gracilis, R. ambrosius, R. glivicensis), which negative influence on tree seedlings depends on the capability of the species to produce a big, dense bush in a short period of time thereby increasing shade; III – species with erect and relatively sparsely growing stems (R. idaeus), which are not a threat for the young forest plantations. Species with intermediate features (e.g. R. nessensis) may have a negative impact on young plantations generating a large, dense aggregation, however in most cases their populations only grow sparsely and do not hinder the growth of tree seedlings.
