    Opis:
    Managed forests, which account for the vast majority of woodland areas in Poland, play a major role in preserving biodiversity. The objective of this work was to determine the diversity of woody microsites in a managed forest covering 27 ha of land in Polanów Forest District (north−western Poland). The study was conducted in 2014 on 20 sampling plots with an area of 0.04 ha each. An inventory of deadwood was conducted involving standing dead trees, snags, stumps, and lying deadwood with a diameter of at least 7 cm (in the case of standing deadwood, the diameter was measured at breast height). Deadwood was classified according to a five−level decay scale. The studied forest was found to contain an average of 26.9 m³/ha of deadwood from several tree species. Lying deadwood accounted for 17.3 m³/ha, standing dead trees for 0.9 m³/ha, snags for 4.9 m³/ha, and stumps for 3.8 m³/ha. Deadwood in all decay stages was identified. The most abundant category of deadwood was moderately decomposed wood in decay stage III (31.3%), followed by decay stage II (24.4%), and decay stage IV (19.7%). Deadwood (both standing and lying) was also very diverse in terms of piece diameters. The diameter at breast height of standing dead trees was up to 26 cm, and that of snags up to 50 cm. The thickest pieces of lying deadwood were 48 cm in diameter. However, pieces of less than 35 cm in diameter accounted for 96% of the total volume of lying deadwood. The volume of deadwood in the studied forest stand was very large, much higher than the average for Polish forests in general (5.8 m³/ha). Deadwood was highly varied and contributed to a substantial diversity of organisms that depend on it, as shown by previous research. Wapienny Las is an example of a managed forest that plays an important role in preserving woodland biodiversity.

    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:
    The aim of the study was to characterize the state and dynamics of dead wood resources in the stands of the Świnia Góra strict forest reserve, which was excluded from use for a longer period of time (from 1938/1953), and to compare the results with the state and dynamics of living trees resources. The reserve covers 51 hectares of an upland forest in the Świętokrzyska Forest (central Poland). Data was collected in 2000, 2007 and 2014 on 95 systematically distributed 500 m2 sample plots. The location and dimensions of living trees, standing dead trees (snags, including stumps) and downed trees (logs) on each sample plot were determined and measured. The decay stages of dead wood were estimated using a four−point scale classification. The average volume of dead wood was 198 ±32 m3/ha (43 ±8% of living trees) in 2000 and 138 ±17 m3/ha (24 ±3%) in 2014 (fig. 1). The ratio of the volume of snags to logs decreased from 30 ±5% in 2000 to 24 ±6% in 2014. Silver fir was the dominant species among both living and dead trees (fig. 2). The share of dead wood volume in decay stages 1 and 2 was the highest among snags, while in stages 2 and 3 – among logs. The number of highly decomposed wood increased in the period 2000−2014 (fig. 3). The decay rate of wood calculated over a 7−year period was more rapid for logs (fig. 4). In the period of 14 years, 119 ±23 m3/ha of dead wood underwent a complete decomposition. Volume of trees that died within that period was 59 ±10 m3/ha (fig. 5). The complete decomposition of snags amounted to 64 ±10% and logs to 58 ±5% of the initial dead wood volume. The dead wood resources in the investigated period were not balanced: the amount of decayed wood was larger than the amount of wood replenishing the resources. The lack of this balance was due to the lack of the balance of living trees – dead wood resources were insufficiently replenished by trees that had died during analysed 14 years. The dead wood resources at a level of approximately 200−230 m3/ha might be balanced via their continuous replenishment by newly died trees in the amount close to the current volume increment.

    Opis:
    Dead wood in the city parks is removed for safety and aesthetic reasons. ‘Polesie Konstantynowskie’ nature reserve (9.8 ha) located in the western part of Łódź is an exception. In this reserve dead wood is left for natural decomposition. So far in this reserve research was conducted on the vascular flora and stand structure only, but the amount of wood was not measured. The aim of this study was to assess the volume of coarse woody material of various types (coarse woody debris, snags), species, size, (dbh and height) and decay classes. The study was carried out in 2010. The volume of coarse woody debris was estimated with a method proposed by Van Wagner [1968]. The criterion of division into five decomposition classes follows Maser et al. [1979].
