Opis:
One of the greatest challenges of nature conservation is to identify and locate networks of protected areas, which will preserve the biodiversity. The paper aims to show the ornithological value of the Sobibór Forests (E Poland) and to emphasize the fact that the network of Important Bird Areas (IBA) and Special Protection Areas within Natura 2000 (SPA) may require additions. The study was conducted in the period of 2008−2016, mainly on forested areas occupying 256 km2. The Sobibór Forests are characterized by a large diversity of habitats, but are mainly covered by Scots pine Pinus sylvestris. High diversity of wetlands and marshlands make the Sobibór Forest unique within the country. Three methodologies were used to estimate population size of chosen species: sampling, census and random observations. 31 species from Annex I of the Birds Directive plus 25 species of SPEC or non−SPECE category were observed which allows to consider this area as one of the most valuable for avifauna in Poland. Six breeding species classify the Sobibór Forests as the IBA and SPA. These species include Black Stork Ciconia nigra (8−13 breeding pairs), Common Crane Grus grus (80−120 breeding pairs), Grey Great Owl Strix nebulosa (0−7 breeding pairs i.e. 50−100% of Polish breeding population), Eagle Owl Bubo bubo (6 breeding pairs), White−backed Woodpecker Dendrocopos leucotos (40−70 breeding pairs) and Grey−headed Woodpecker Picus canus (20−40 breeding pairs). Six other species show potential for qualification, but not enough data has been collected yet. The list of this specie includes: Short−toed Snake Eagle Circaetus gallicus, Common Snipe Gallinago gallinago, Stock Dove Columba oenas, European Nightjar Caprimulgus europaeus, Collared Flycatcher Ficedula albicollis and Bluethroat Luscinia svecica. The Sobibór Forests occupy a small area compared to other IBA forests. However, the number of breeding species classifies the surveyed area as 7th among other IBAs. Moreover all eligible species may be considered as a bioindicators of the natural state of the forest. This is proof of the high natural value of this area.

Opis:
The purpose of the stratification is to group stands basing on the homogeneity of the measured feature. During periodic forest inventory in Poland, strata are created on the basis of age and the main species in stand within the boundary of forest district. In this work an improvement of distinguishing the strata during the forest inventory is presented. Three variants are considered: (1) distinguishing homogeneous strata in boundary of the whole forest district, not separately in forest subdistricts, (2) splitting species−aged strata into homogeneous substrata with respect to site quality, and (3) dividing strata of stands in the regeneration class with respect to stand density. Study was conducted in four mountain forest districts located in the Kłodzko Basin (SW Poland). Total area of these stands amounted to 43,052 ha, where 6,648 sample plots were established during the periodic inventory. ANOVA was used to test significance of the differences in tree volume and to assess variability reducing in distinguished substrata. Results indicated that in stands with age up to 70 years mean volume of trees on the sample plot does not differ significantly between sites, but in older stands difference was significant. Dividing age−species strata of stands older than 70 years into substrata according to site conditions influenced reduction of volume variability from 10 to 57% in newly created substrata. Dividing strata consisted of stands in regeneration class according to stand density index allowed to decrease the volume variability from 9 to 20%. Mean volume of trees in stands on similar sites does no differ significantly between subdistricts in the same forest district. Strata distinguished within the whole forest district are bigger and represented by more sample plots than on the subdistrict level, which significantly reduced standard error of volume and improved effectiveness of stratification in forest inventory.

The impact of narrow (up to 2 m), medium (up to 3.5 m) and wide (>3.5 m) tourist trails on the surrounding environment was investigated. On wide trails, the value of soil erosion and compaction indices was found to be the highest, while the herb height index was the lowest indicating the greatest impact of wide trails on the environment. The phytosociological relevés were used to determine ecological indicator figures. Wide trails were characterized by higher thermal and continentalism indices and lower pH and trophic indices. The proportion of therophytes and geophytes was higher, while of hemicryptophytes, phanerophytes and chamaephytes on wide trails were lower than on medium and narrow trails. All the analysed indices pointed to a stronger impact of wide trails on the environment in comparison with medium and narrow trails.

Opis:
The paper presents the results of the study on biomass volume and annual production of oak stands in the Niepołomicka Forest. The analysis was based on the material collected from 59 circular sample plots where oak accounted for more than 50% of the volume of the tree layer. In the total biomass of the tree layer amounting to about 225.3 t·ha–1, the biomass of the shrub layer (underbrush) is about 2.3 t·ha–1. In the tree layer biomass (about 223 t·ha–1), wood makes up on average 86.4%, bark – 12% and assimilatory apparatus – 1.6%. The share of wood in the biomass increases with the increase of stand age, while that of bark and assimilatory apparatus declines. The proportion of these elements in the dry mass production (on average 9.8 t·ha–1·year–1) is somewhat different. Almost 35% of its volume is assimilatory apparatus whose share increases with stand age. The increment of bark is about 9%, while of wood it is 56% of the annual biomass production of the stands under analysis and slightly decreases with stand age.

Opis:
Erysiphe alphitoides causes the most common disease of assimilation apparatus of oaks of different age. It is believed that the pathogen overwinters in buds of the host plant or in the cracks of the bark. The aim of the study was to search for the presence of E. alphitoides in buds, leaves, and wood of sessile oak shoots using molecular techniques. Two hypotheses have been tested: (i) oaks are infected by E. alphitoides, and (ii) the pathogen overwinters in the host plant buds. The samples used in the study were collected form sessile oak trees (Miradz Forest District; 52°41'23.197'N, 18°25'33.942'E) in 2017, and consisted of dormant buds (collected in May), young leaves (collected in June), leaves with visible symptoms of the disease (collected in August), shoot with sip and surface layers of wood (collected in December). Additional part of buds was collected in May 2018. The PCR reaction was carried out with primers specific for E. alphitoides and E. hypophylla. For species identification Sanger method was used. The resulting sequences were compared using BLAST algorithm with reference sequences deposited in the NCBI database. Sequences from isolates obtained from leaves showed 97−99% similarity to the reference sequence of E. alphitoides. Pathogen did not occur in the superficial layers of shoots and buds. As some studies show, at very low temperatures (below –20°C), the mycelium of the pathogen dies, therefore further study should be undertaken on wintering of the pathogen causing the powdery mildew disease on oaks. It also should be examined whether the pathogen overwinters in the form of bagnial spores produced in chasmothecia overwintering on leaves, in the leaf buds, or in bark cracks, and whether the wintering site of the pathogen is related to the age of trees and or to the stands where the trees grow.

Opis:
The empirical material used in the studies took in measurement results. The measurements were carried out on 221 circular plots distributed systematically in an area of about 5826 hectares of stands in the Niepołomicka Forest where pine accounts for more than 50% of volume in the upper tree layer. The mean biomass of these stands is about 173 t·ha–1 of which 80.6% is pine biomass. The biomass volume and increment depend equally on stand age, habitat conditions and, in some age classes, the share of admixture species. The proportion of wood in biomass production markedly declines with stand age while that of the assimilatory apparatus increased.

Opis:
On 127 experimental plots were classified into different forest site types according to vegetational criteria, 16 main soil properties were analysed and their content in a 100 × 100 × 150 cm soil lump was calculated. The expert system and the linear discriminant analysis showed different soil properties and their groups enabling stronger or weaker division of the examined sites into forest site types. The content of 0.1−0.02 mm fraction, the content of <0.02 mm fraction, the concentration of H+ ions as pH reaction in H20 and the content of mobile N were pointed to as those which better distinguish coniferous forest (B) from mixed coniferous forest (BM), mixed coniferous forest from mixed broadleaved forest (LM) and mixed broadleaved forest from broadleaved forest (L). The other soil properties in the expert system showed a weaker strength in differentiating the examined sites into different forest site types according to vegetational criteria.

Opis:
Despite the fact that only parts of the Białowieża Forest are protected as a national park and nature reserves, the forest is nevertheless as a whole considered a U NESCO Natural Heritage Site, Biosphere Reserve and an integrated Natura 2000 site. In the presently ongoing debate on the conservation priorities regarding the natural value of this forest and the current bark beetle outbreak, two distinct approaches can be recognized: (1) management assumed to involve considerable interference with the forest ecosystems; (2) maintenance of ecological processes and spontaneous restoration of the forest communities. The Białowieża Forest – especially its strictly protected parts – is a “bastion” where species characteristic of ancient forests (including so-called primeval forest relicts) have survived until today. This has been achieved by maintaining the forest’s complexity in areas with considerably reduced human influence, but most of all by maintaining a full spectrum of forest communities, naturally developing forests diverse in age, species composition and spatial structure including stand dieback and breakdown. The following factors need to be taken into account in the protection of the Natural Heritage Site: (1) the internationally recognized value of the Białowieża Forest including its biodiversity, the level of preservation of forest communities and the ongoing natural processes; (2) existing documents and policies concerning nature conservation; (3) research findings from the Białowieża Forest and other natural forest complexes. The key priority is to limit any activities in this forest to an indispensable minimum, mostly concerning security close to roads and tourist tracks as well as collection of fire wood by locals. Without this strict protection, successive and slow anthropogenic transformation will result in the Białowieża Forest sharing the same fate as other forest complexes of the temperate climate zone in Europe or America and lose its globally appreciated value.

Opis:
The correct assessment of the site conditions is the basis of the good management of forest areas. The aim of this study was to find a set of soil properties, which allow separating the diverse sites in terms of the soil productivity. We used 180 locations in the Carpathians and the Sudety Mountains for testing. The study plots were located in transects from the foothills to the top along the slopes, taking into account the variability of site conditions, geological substrate and exposition. The index was calculated on the basis of the content of <0.02 mm particles, the sum of exchangeable base cations, soil acidity and the ratio between total N content and organic C in the humus−mineral horizon. The soil trophic index for mountain areas (SIGg) that include the climatic factor was introduced. The factor is defined as the 650/altitude ratio for a given point above sea level. In the mountains, the content of <0.02 mm fraction, the sum of exchangeable base cations and soil acidity were determined in the column of 1 m² of the soil cross section and depth of 1 m (1 m³ of volume) due to the lower depth of the soil profile. The SIGg correctly separates soil of different productivity as the properties closely associated with the stable elements of the soil, expressing its production and properties, which reflect the current state of the soil environment, were used in the construction SIGg.

Opis:
The increasing social demand for food products collecting from the forests has beem observed currently. It should be assumed that one of the more and more important non−wood forest products in Poland is silver birch sap. Research in this area should concern not only the proper methods of its collection and yield, but also the rules of selecting forest stands and trees for its collection, as well in the context of protection of forest ecosystems, especially the quality of the obtained product and the safety of its consumption. The aim of this study was to examine the influence of air temperature on the daily volume of collected birch sap, determine the dependence of the volume of sap obtained on the selected physical parameters of the sap, as well as determine if there are changes in the values of the parameters tested as a function of time. It was not proved that the volume of the daily sap leak is related to the parameter of the refractive value, dry matter and electrolytical conductivity. It was found that the volume of the sap obtained is not significantly affected by the temperature on the day of the collection nor at the night immediately preceding the leak, while the relation between the intensity of the leak and thermal conditions several tens of hours earlier was indicated. Moreover, it was not shown that there was an optimal, determinable term in which birch sap is characterized by the most favorable parameters in terms of suitability for the production of birch syrup. It was also found that in the case of commercial birch sap harvesting on large scale, it is advisable to harvest and combine the sap from as many trees as possible. The necessity of further studies on the food and industrial usefulness of birch sap, including geographical, habitat and age variability of birch stands was underlined as well.
