The work studied the effects of site conditions on the amount of deadwood (DW) in managed forests in south−western Poland. Measurements included standing dead trees, snags with a diameter at breast height of at least 7 cm, and lying deadwood (logs, branches, uprooted trees, etc.) with a diameter at the thicker end of at least 10 cm. The study excluded snags and deadwood pieces with a diameter of less than 7 cm as well as stumps. Site conditions are presented according to the Polish site classification system taking into account both site fertility and water abundance. With respect of the fertility gradient, sites are classified as dystrophic, oligotrophic, mesotrophic, and eutrophic. In terms of water abundance, there are two types of sites: mesic (low or very low contribution of groundwater, rainwater, and floodwater, with an approximate springtime water table depth of more than 1.8 m) and moist (moderate or considerable contribution of groundwater, rainwater, and floodwater, with an approximate springtime water table depth of 0.5−1.8 m). We analyzed data from 2522 sampling plots with area ranging from 50 to 500 m² and depending on forest stand age. The plots were established in forest stands older than 21 years old. The predominant tree species in the study area were Pinus sylvestris, Quercus robur, Quercus petraea, Betula pendula, Fagus sylvatica, Alnus glutinosa, Fraxinus excelsior and Picea abies. In a separate analysis of data from 233 sampling plots, we studied the relationship between DW volume and the site index evaluated using a five−level classification (level I denotes sites with the highest productive capacity). Forest stands aged >80 years with the dominance of Pinus sylvestris were studied. The study showed a significant influence of site conditions on the DW volume in managed forests. Forest stands exhibiting better site conditions not only provided more timber, but also contributed with a greater amount of deadwood to the ecosystem. Forest stands with a site index of I contained as much as 4.9 m³ of DW/ha, while stands with a site index of III only 2.4 m³ of DW/ha. In terms of the 8 studied site types, it was also found that the average volume of DW increased with site fertility. The lowest volume of DW occurred on very nutrient−poor and mesic sites (0.6 m³/ha). In contrast, nutrient−rich and moist sites contained 15 times as much DW (9.5 m³/ha). Of paramount importance was water abundance. The volume of DW on moist sites was on average by 2.2−4.5 m³/ha higher than on mesicsites with the same fertility.

The paper analyzes two methods of deadwood (DW) measurements on circular sampling plots. In the first method, the volume of DW is measured within the circumference of the sampling plot irrespective of the fact whether the live tree was located inside or outside the plot. The other method requires the measurement of only that DW, which can be attributed to trees that originally grew within the sampling plot. This requires identification all debris fragments originating from those trees both within and outside the sampling plot. Additionally, the paper compares the results obtained using Smalin's and Huber's formulas and discusses the influence of decomposition stage on the calculated volume of lying deadwood. Measurements were conducted in two stands. In each of them 20 circular sampling plots (4 or 5 ares) were established. In both stands, the second investigated measurement method led to a lower mean DW volume (by 6.3% and 27.2%). In practice, it was very difficult to identify DW from the outside of the sampling plots as high trees growing close to the plot had their fragments lying up to several dozen meters away. If a tree was very fragmented upon falling, it was difficult to find all the relevant pieces of DW and determine whether they derived from the sampling plot or not. The volume of lying DW calculated according to Smalin's formula was by 5% higher. In case of 7.7% of the 194 inventoried fragments of lying DW the transverse cross−section changed from circular to misshapen. The application of formulas accounting for decomposition decreased the calculated volume of lying DW by 5.1%. Taking into consideration the time−effectiveness and accuracy of measurements, it has been found that for most stands the best method is to measure the ends of DW pieces, calculating the length of segments from polar coordinates (using the measurement principles presented in the figures). In addition, especially in measuring large trees, one should take into account changes in shape attributable to decomposition, which may influence the calculation of DW volume. It is recommended that all DW fragments within a circular sampling plot should be measured irrespective of whether the tree from which they derive grew inside or outside the plot.

Awareness of the importance of the presence of deadwood in forest ecosystems has increased in recent decades. Today, deadwood is not only recognized as a key element in carbon sequestration, nutrient supply and water retention, but is also known to be a reservoir of saproxylic species (species associated with the decay of wood on living and dead trees). The amount of deadwood in clear−cut forest is currently higher than 100 years ago. The issue of how much deadwood and of what quality (including size) there should be in order to promote the conservation of saproxylic biodiversity and sustainable forest management is still vivid. Mycological analyses to determine (i) structure of fungal communities in Scots pine wood debris, (ii) sources and reservoirs of fungi, (iii) nutritional preferences of fungi, and (iv) potential rate and dynamics of wood decomposition were carried out on an ‘old' and ‘fresh' wood (stumps, branches and boughs) from Jedwabno Forest District (north−eastern Poland). Fungi from 62 wood samples were isolated on two artificial media (PDA and SNA) and identified according to their morphology. Eleven species of Zygomycota, 79 of Ascomycota and 15 of Basidiomycota were detected. The majority of species (91%) colonized many samples. Only 9% of species colonized single samples only. The most common species, with high rates of colonization, included Acremonium spp., Alternaria sp., Aspergillus spp., Aureobasidium pullulans, Cladosporium spp., Epicoccum nigrum, Lecythophora spp., Mariannaea elegans, Ophiostoma + Sporothrix spp., Penicillium spp., Phialocephala spp., Phialophora spp., Phlebiopsis gigantea, Phoma spp., Sarocladium strictum, Scytalidium lignicola, Sydowia polyspora, Trichoderma spp. (mainly T. harzianum and T. viride) and Umbelopsis spp. A few species occurred only on stumps or only on branches. More species occurred on 'old' wood than on 'fresh' wood. The average level of sample colonization by a single fungal species was higher (non−significantly) on 'old' than on 'fresh' wood, and on branches than on stumps. The results show that deadwood is a habitat for many fungal species that occur in succession. The presence of deadwood in clear−cut forest and in its neighborhood is necessary for the conservation of saproxylic fungal diversity and ecological sustainability of forests
