    Opis:
    The aims of this study were to demonstrate the role of forests in the Roztoczański National Park as a refuge for rare and endangered saproxylic Coleoptera as well as recognition of entomological fauna related to dead wood. The study was conducted in the strictly protected are of Bukowa Góra from 20th April to 30th September 2012 and focused on the wood of beech and fir. We inventoried saproxylic beetles by means of nine ‘Netocia’ traps, which resulted in a total of 135 recorded species, of which 52 had not been reported in the park before. Twenty-one rare and endangered species were found. The high number of new species in the Roztoczański National Park indicates a high biodiversity value of the area. Our studies therefore show that the strictly protected area of Bukowa Góra is a biodiversity hot spot of saproxylic Coleoptera.

    Opis:
    The aim of this research was to determine the composition of microscopic fungi colonizing Norway spruce dead wood depending on the degree of decomposition of wood and the location in the Tatra National Park (TPN; southern Poland). The work included lying and standing dead wood of Norway spruce as well as tree stumps. The sampling plots were located in the Białka Valley (eastern part of the TPN) where the forests are unmanaged and area is mostly under strict pro− tection, and in the western part of the Park, in the Chochołowska Valley, where the majority of forests is privately owned and managed (landscape protection). Samples were collected three times in the growing season, in spring, summer and autumn 2016. The sampling plots were located in the forests covered by different forms of protection: strict, active and landscape. The dominant microscopic fungi inhabiting analysed Norway spruce dead wood in selected regions of the Tatras are fungi belonging to Trichoderma genus: T. harzianum: T. polysporum, and T. hamatum. A much greater diversity of fungi species isolated from the dead wood was found for the Białka Valley, subjected to strict and active protection, than Chochołowska Valley, where forests are subject of the economic utilisation. More species and colonies were obtained from lying and older dead wood than from the stumps in the higher classes of distribution.

    Opis:
    In the end of 2013 the Norway spruce stands in the Kościelska Valley in the Tatra National Park (S Poland) were severely damaged by the wind. In the next year about 22,000 m3 of timber from broken and fallen trees was processed and removed from the active protection zone, whilst in the strict protection zone those trees were left. In 2014, when the presented survey started, the infestation of lying and surrounding standing trees was very low, but starting from 2015 an intensive bark beetle Ips typographus outbreak affected the survived stands. No−intervention strategy was implemented by the national park in both zones, regardless their formal status at that time as well. In 2015 a set of 10 observation plots (200 trees in total) was established in both active and passive (strict) protection zones (5 plots in each zone). In 2017 a new set of 12 plots (240 trees in total) was installed (6 plots in each zone). On each plot the breast height diameter of all trees was measured and the relative mortality of trees (share of attacked spruces) was recorded each year. The infestation density and sex ratio were defined on the 25×25 cm bark samples taken from 138 trees in 2 trunk sections located 1.5−2.0 above the ground and in the midway between tree and crown bases. The bark beetle attack on living spruces in 2015 differed between the active and strict protection zones. The relative tree mortality was lower in active than in passive protection zone (20 and 39% respectively), but later it gradually came to be similar in both parts of the area (73.3 and 77.5%, respectively in 2017). In the initial outbreak phase, thinner (weaker) trees were attacked, and in the following years – stronger ones, although in the active protection zone the opposite pattern occurred initially. The attack density decreased in subsequent years, being higher in active protection zone, with gradually decreasing difference between zones. Thicker trees were attacked with lower intensity. The share of females, higher in active protection zone (68.2 vs. 63.9%), gradually decreased to (57.9 vs. 51.2%). The initial decrease of bark beetle attack intensity in the active protection zone gradually disappeared after the no−intervention strategy was applied. The resulting extended bark beetle infestation and its increasing intensity in both parts of the area, demonstrate the appropriateness and effectiveness of active protection measures applied in 2014.

    Opis:
    Major results of the 45−year−long study on the dynamics of strictly protected forest stands, using 3 permanent study plots, 25×100 m each, located on a former narrow strip clear cut established in the beginning of the 20th century on the northern slopes of the Mt. Łysica (the Świętokrzyskie Mountains, Central Poland) are presented. The general development of forest stands is analysed, including change of overall density, tree mortality rate (general and by species), dynamics of basal area and average tree diameter, competitive ability as well as changing role of particular species (mainly European beech, silver fir, sycamore and Norway spruce) in formation of the general stand structure. The results of the study are compared with other investigations of similar type.

    Opis:
    The line intersect method is recommended for coarse woody debris (CWD) inventories. This is due to the fact that for the CWD volume estimation with the assumed standard error (SE), the total time of measurements using line sampling units is shorter than when using the fixed−area sample units. The aim of the research was to determine: (1) the number and size of sample units whose use will allow achieving the assumed SE of the CWD volume estimation, and (2) dependence of this number and size of sample units on the quantity of CWD. The research material was collected from 131 sample units (sampling lines) with a length of 50.48 m each. They were systematically located in the stands (128 ha) on Bukowa Góra in the Roztocze National Park (south−east Poland). Data concerning the intersection points of the sampling line (in relation to its beginning) with the axis of a downed log, made it possible to simulate the measurement using shorter sampling lines (4, 8, …, 44 m) than the original ones. The simulation was performed using the original data (when the average CWD volume was 73 m3/ha), which also represented an inventory unit in which the CWD volume accounted for 10, 40 and 70% of the original value. These data were obtained by a random elimination of the appropriate portion of trees. The relationship between the single−tree−plot coefficient of variation (calculated for such a size of a sample unit which on average contains only one log) and the length of the sampling line was determined (figs. 2 and 3). On this basis the number of sample units necessary to obtain the assumed SE value of the target variable was determined (tab. 1). Using the data on labour consumption of individual measurement operations, the total working time was calculated for such a number of sample units that would guarantee obtaining the assumed SE of the CWD volume estimation (tab. 2). The total time of measurements was longer in an inventory unit with scarcer CWD resources (figs. 5 and 6). The optimal (due to the time of measurements needed to achieve the assumed SE of the CWD volume estimation) line length occurred within the range of 4−150 m. The use of sample units with a length of 60−150 m each was recommended in forests with the average CWD volume over 30 m3/ha, and with a length of 150−200 m in forest with sparser CWD resources.
