    Opis:
    The paper provides a description of climatic requirements of Scots pine (Pinus sylvestris L.) trees from five populations from the Tatra National Park, the Pieniny National Park and the Ojców National Park. Differences in climatic conditions between these parks were reflected in incremental behaviour of pines growing on these sites. The main factors limiting pine radial increments were: in the Tatra Mts. – warm weather in July, in the Pieniny Mts. – winter thermal conditions, while in Ojców – moisture conditions in the spring.

    Opis:
    This study aimed at quantitative spatial analysis of forest cover transformation in the Western Bieszczady Mts. based on two areas: Bieszczady Wysokie Mts. (from 1852 to 2004) and Baligród Forest District (from 1938 to 1996). Raster maps were created to illustrate two cover types: forest and non−forest. Using ACSII files and Fregstats 3.3 program, landscape metrics were calculated for whole landscape and both cover types. Landscape structure became simplified. Forest cover area increased with simultaneous patch number decrease and aggregation degree increase. Non−forest cover underwent inverse changes, such as area and aggregation degree decrease. Patch number change differed in both areas in relation to various processes of patch creation.

    Opis:
    The field study was conducted within an acclimatization enclosure in Radziejowa Valley and in a clearing in Tyskowa Valley, close to Baligród (Bieszczady Mts., south−eastern Poland) during two seasons: spring and summer. The aim of this study was to assess browsing intake by Polish koniks (tarpan type) in enclosures and free ranging conditions. The measurements were done along transects in the enclosure and around the clearing, inward of the forest stand. In all scenarios, koniks preferred shrubs (rose and plum) mostly avoiding trees. The amount of taken browse depended on the amount of preferred shrubs available.

    Opis:
    Swedish whitebeam (Sorbus intermedia (Ehrh.) Pers.) is a species with a very limited range. It occurs only in southern Scandinavia and along the Baltic coast, without the Gulf of Finland. Its southernmost natural localities are situated in northern Poland. They are few in number, grouped in two regions: near Kołobrzeg and the Gulf of Gdańsk. Currently, only three of them survive: vicinity of Sarbinowo as well as Kępa Redłowska and Przylądek Rożewski. In the Podtatrze region, S. intermedia has long been planted along roads, on green areas, in gardens and parks, among others in Zakopane. In the Tatras it did not appear, so it is a foreign species for this region. Currently, in the Tatra National Park there are several hundred fruiting specimens of this species growing. Most of them are part of a forty−year−old stand planted on the back of the Grzybowiec ridge. The aim of this research was to recognise the health status of S. intermedia. Phytopathological research was conducted in 2018 in the Tatra National Park. Leaves that were subject to analysis were decontaminated in 1% surfactant solution of sodium hypochlorite. Their fragments of about 0.5 cm were placed on Petri plates with PDA (Potato Dextrose Agar). The growing fungal colonies were consequently re−planted onto PDA slants for further culturing and taxonomic identification. The pathogens were identified basing on morphological features and with molecular tools. All S. intermedia in the Tatra National Park showed disease symptoms. Infected S. intermedia leaves were colonized by A. alternata, which fraction amounted to over 40%. The following dominant was B. exigua with over 30% share. F. avenaceum (close to 10%) and E. nigrum and D. macrostoma were also found. The S. intermedia population growing in the Tatra National Park is characterized by a poor condition, which may in the future affect the population of this plant in the Tatra Mts.

    Opis:
    The study analysed short−term rhythm of radial increments of spruces from different elevations and their climate drivers. Two Norway spruce stands were chosen at the lower and upper montane forest belt in Roztoka Valley (DR) (1000−1050 m asl, 49°13 N, 20°04 E) and in Hala Gąsienicowa (HG) (1500−1550 m asl, 49°13 N, 20°04 E). 20 trees were sampled and one increment core was taken per tree. The sampled trees were dominant or co−dominant individuals without visible damage. To remove the age trend, the tree−ring widths values were standardized to annual sensitivity indices. Principal components analysis, bootstrapped correlation and pointer years analysis were used to classify sensitivity of investigated series and identify the climate factors, which determined annual variability of the radial increments. Pointer years were also determined by using interval trend method. The first principal component (PC1) accounts for 39% of the variance among all tree−ring series. The second component (PC2) accounts for 15% of the variance among the tree−ring series and divides the series into two groups. This grouping seems to express the lower and higher locations of the sites. The sensitivity series of spruces from both sites had different as well as similar features. These differences resulted from different tree's reaction to temperature in early spring and precipitation in spring and summer. The similarity of increment reactions of spruce from both sites was caused by their similar sensitivity to sunshine duration and precipitation in January, temperature in June and July, sunshine duration in June. Cluster analysis confirmed the impact of the climatic factors on differences of increment reactions of spruces. A number of the pointer years was higher at site located in the upper montane forest belt. Their chronology also consisted a stronger climatic signal. The climatic sensitivity which was specificity for a given climatic belt was recorded into individual tree series. For that reason, the tree−ring width series of trees are useful in the estimate of a climate−increment relationship. They can also be used to dividing dendroclimatic belts.

    A few reports are concerned with sime moulds biota of anthropogenic areas. Majority of areas in the Beskid Śląski lower montane forest belt is covered by monoculture of spruce, planted in the nineteenth century. Intensive field studies were carried out during two vegetative seasons of 2006 and 2007 on the thirty hectares area of planted spruce forest. Two hundred forty four specimens were collected – single sporangium and its groups. In the early spring in 2006 and 2007 five species associated with melting snow were recognized. A total of thirty four species were recorded, among them: Fuligo septica (L.) F. H. Wigg., and Lycogala epidendrum (L.) Fr. were the most common. Ten taxa were very rare. They were noticed only once. Lamproderma echinosporum Meyl. and Stemonitopsis gracilis (G. Lister) Nann.−Bremek. were recorded for the first time in Poland.

    Opis:
    The study assesses the effect of applied cuttings on the transformation of the species composition, structure and development of the forest towards selection forest type. The described control unit was established in 2000 in the Krucze Mts. (southern Poland) within the programme of silver fir restoration in the Sudety Mts. The working hypothesis was based on the advantageous effect of the selection management system on fir trees. 46 permanent circular sample plots of 0.05 ha each were established and diameter at breast height measured on all trees along with height of 2−3 trees growing closest to the plot center. Measurements were repeated in 2004 and 2013. The greatest share in the growth increment was recorded for the most numerous species (spruce and fir). Only spruce and beech were important in the group of young trees (recruitment), which did not include fir or larch. The timber resources increased from 339 in 2000 to 381 m³/ha in 2013, which indicates that not whole current increment was harvested. The increase in the growing stock follows the reduction in the number of trees per hectare from 361 to 317. Thus the number of young trees did not compensate for the losses. As a result the investigated unit is not in the state of equilibrium and in the future more work and care should be devoted to the regeneration. Fir turned out to be a species with the greatest production potential. In the first period growing stock of this species amounted to 17%, while the increment was over 26%. In the latter the increment reached 34%. The most important objective of the selection cuttings in this concrete unit should be to tend for regeneration and trees at low diameter sub−classes at the expense of use of trees with target values of diameters at breast height and disturbing the selection cutting structure. It is advisable to increase the share of fir in the structure of analysed unit.
