Opis:
The study presents the methodological and applicative scope of mapping and assessment of forests ecosystem services within the Integrated Environmental Monitoring Programme (IEMP). The IEMP operates within the State Environmental Monitoring Programme performed under the coordination of the Chief Inspectorate for Environmental Protection. The program targeting at the ecosystem services is implemented in 11 IEMP research catchments, which are located taking into account a diversity of the landscape−ecological zones and physical−geographic regions across the country. The research, being conducted since 2015, includes: typology of ecosystems based on land use and land cover data, assessment of the potential of ecosystems to provide services using the bonitation matrix, and identification of ecosystem services indicators on the basis of the IEMP measurement programme. The results indicate that the differentiation of ecosystems mosaic between research catchments leads to a specific mixture of ecosystem services for each catchment. Regional variation of the ways and intensity of the ecosystems use by society determines the different importance of individual services. It can be concluded that the IEMP provides helpful data for recognizing the structure and value of forests ecosystem services in Poland. The vast scope of the IEMP measurement programme and diverse character of research catchments give the opportunity to investigate a broad spectrum of regulating ecosystem services. Further efforts should focus on strengthening the interpretation of the measured parameters in the context of benefits for human, and determining conditions for extrapolation of obtained values to other areas.

Opis:
The paper presents declarative opinions of 239 tourists who visited the area of the Krynki Forest District in July−September 2013. The opinions were collected in direct interviews using of a questionnaire. The analysis distinguished two groups of respondents: 135 people (56,5%) who visited the forest district for the first time, and 104 respondents (43,5%) for whom it was the subsequent visit. We analysed the opinion of tourists on such problems as: (1) anthropogenic threats to the forest ecosystem, (2) factors constituting a threat to visitors to forest areas, and (3) forms of recreation and rest that can be implemented in forest areas. To examine the significance of mean differences between analysed groups of respondents that differ in experience and hypothetical readiness to declare the amount of WTP> 0, the Mann−Whitney test was used. Respondents considered forest fires and garbage left in the forest as the greatest threat to forest ecosystems, while among factors threatening people resting in forest areas, respondents pointed to the natural factors such as vipers, ticks and mosquitoes. Respondents considered that admissible forms of recreation and rest in forest areas are sport and cross−country races, horse riding and cycling, while ones that pose a threat to forest ecosystems, e.g. organization of mass events or bonfires and family events with barbecue, should be prohibited. No impact on differences in the opinions declared by the respondents, their tourist experience or readiness to declare the amount of WTP was disclosed.

Opis:
The article overviews the role of bats in the forest ecosystem (especially the European forest), the impact of environmental pollution on the forest and bats, and the issue of bats indication of the forest environment condition. Existing data on the transfer of pollutants to the environment and between the aquatic and terrestrial environment are reviewed. The water environment is an important receiver of industrial pollution, which then transfer to the terrestrial environment i.a. through insect larvae. Bats as predators hunting for the insects, which undergo part of their life cycle in water (including Diptera: Chironomidae), play an important in this cycle. Another source of bats intoxication are terrestrial insects feeding on plants that transfer toxins that settle on the leaves surface further in the food chain. Bats as predators of the first or even second level store in such a case substances like heavy metals in their bodies. Air pollutants also have a direct impact on forest stands, causing (in zones of strong industrial pollution) the inhibition of tree growth. The result is, among other things, a smaller number of hollows, which in turn is manifested indirectly through weaker settlement by bats (and birds) of these stands. Bats communities inhabiting the forest depend on such factors as the availability of roosting places, the age struc− ture and spatial structure of the stands. All these features (as well as others related to them) are subject to modification through economic forestry, which causes changes in the bat communities. Ecological research of forest bats shows variability of settling of managed stands, as well as diversified species composition, especially smaller presence of typically forest bats connected ecologically with forests (e.g. western barbastelle Barbastella barbastellus or lesser noctule Nyctalus leisleri), in favor of bats preferring open spaces and built−up areas (serotine bat Eptesicus serotinus). This is probably the result of changes in the age and spatial structure of the stand. On the basis of the collected information, it was concluded that bats are a valuable indicator of the condition of the forest environment.

Opis:
Cavities are important, natural components of forest ecosystems, conditioning the high level of biodiversity. They are formed either as a result of a natural process of wood decay caused by fungi or as excavations made by woodpeckers Picidae. Distribution and density of cavity trees are regionally diversified and dependent on species composition and age of the stands as well as the management way. In the global scale, decay cavities are much more numerous than those created by woodpeckers. Natural cavities dominated in deciduous forests, whilst woodpeckers−made ones – in coniferous stands. The density of cavities increases along the age gradient due to the growing size of trees and their worse health condition. Cavities in natural forests are more numerous than in commercial, managed ones. This is caused by the removal during the thinning of trees reduced in health, attacked by insects, fungi or mechanically damaged, which are potential places for the creation of cavities. The other reason is a too low age of the final cutting. Moreover, in the managed forest, cavity trees are often removed during sanitary cuttings, although leaving them is recommended. In European forests, the density of cavities is from less than 1 to almost 100 per ha. Natural cavities dominated in most of the studied plots. In Poland, their density varied from less than 1 to 16 per ha. Cavities are habitats and breeding sites of many specialized species of animals from invertebrates to mammals, fungi, and plants. In Poland, cavities are used by about 40 bird species, about 20 mammal species, as well as several hundred species of insects. According to the Polish forestry regulations, trees with cavities should be left to natural destruction, but there are no detail recommendations how to search for such trees and what is their required density. The recommendation to leave cavity trees will not contribute to the increase in their number in managed forests, unless one provides wider availability of adequately large trees with a reduced condition. In Polish forests, actions should be taken to increase the number of potential trees, in which cavities may be formed. They should be designed at the stage of tending for young stands. The minimal density of cavities in managed forests should be in the range of 1−3 per ha in coniferous and mixed forests up to 100 years old and above 3−4 per ha in stands older than 100 years, while in deciduous forests these values should equal to 2−5 per ha and 4−6 per ha in younger and older stands respectively.

Opis:
Alien tree species, due to their longevity, manifest their invasive potential after several decades from introduction. For the high threat to biodiversity, there is a need to analyze the risk of introduction connected with numerous alien tree species introduced in the various forest ecosystems. We aimed to assess the productivity potential and effect of alien Carya ovata on understory vegetation. Our study was conducted in the oldest (122 years old) tree stand of C. ovata in Poland, located in the Czerniejewo Forest District (western Poland). We analyzed C. ovata tree stand features and vegetation traits within the forest community and compared with natural vegetation – oak−hornbeam forest. We found that C. ovata trees had lower dimensions and standing volume than oaks (Quercus robur and Q. petraea) growing in the neighborhood. We also did not find the impact of C. ovata stands on understory vegetation species composition and light availability. Because of the low impact on forest floor vegetation and lack of spread we concluded that C. ovata cannot be classified as an invasive species. Moreover, its introduction was not successful in terms of tree stand productivity.

Opis:
Since several years already, a massive infestation of bark beetle has taken place in the Białowieża Forest, decimating a local Norway spruce population. In consequence, many open areas appeared, practically deprived of trees and other forest vegetation. The existence of such areas has a very negative impact on multiple values of the Białowieża Forest: natural, social, economical and landscape−aesthetic values. The local forest administration prepared a strategy aimed at active restoration of diverse woodland communities typical for the Białowieża Forest in all places, where bark beetle infestation wiped up the spruce stands. Those plans were criticized by representatives of the environmental organizations who blamed the foresters for transforming the Białowieża Forest into ‘plantation’ and claiming that such measures are inconsistent with the existing forest management and protection plan. The postulate of environmentalists is that the recovery of woodland communities should proceed completely naturally. Taking into account the above mentioned controversies, in this paper we examine the issue of natural regeneration in the Białowieża Forest in detail. In particular, we try to determine to which extent this method of forest reproduction enables re−establishment of compositionally diverse woodland communities, distinguished by a high level of biological diversity and able to provide a wide range of commodities and benefits important for today’s society. Based on an extensive literature review we show that a combination of different (abiotic and biotic) factors, influencing establishment and subsequent growth of seedlings and saplings in the Białowieża Forest has long been strongly unfavorable for many tree species. In this regard, one should particularly emphasize the negative role of large herbivores, especially red deer, which is present in the Białowieża Forest since the end of 19th century, when it became a private hunting ground for Russian tzars. The devastating effect of deer browsing on natural regeneration is a well−documented phenomenon and widely recognized problem in the forestry practice. The fencing of young forest generation against game pressure is an indispensable measure, needed to secure the continuous existence of several tree species (first of all those palatable and vulnerable to browsing). Very strong arguments for an active approach to the described problem delivers also a long−term study on natural forest dynamics conducted since 1936. It shows that under conditions of strict protection the regeneration capacity of the Białowieża tree species is very variable. These differences lead to the compositional simplification and impoverishment of many tree stands, with numerous negative consequences for local biodiversity. We underline that an active management strategy is a basic prerequisite for maintaining a diverse character of the Białowieża stands and their ability to provide all important ecosystem services on a sustainable basis. Such a strategy should include, beside of the phase of establishment, also the subsequent developmental stages of new forest generations. The general goal of such a strategy should be to secure a possibly high diversity of tree composition and to enable the development of tree species representing a full range of life−history strategies and playing different successional roles: from typical pioneer species, through intermediate, to climax species.

Opis:
The paper presents the assessment of possible impact of climate change on forest ecosystems in Poland and its consequences in the forest management planning. Scenarios of climate change in the twenty first century do not allow unambiguous determination of the rate and direction of these changes. However, it is believed that climate change could have negative economic con− sequences, which directly or indirectly will affect the deterioration of the environment. Analysis of the possible forms of the impact of climate change on forest ecosystems is particularly relevant in terms of growth conditions. The most noticeable consequences of the changes will concern the threat to the stability of forest stands resulting from the increase in the intensity of trees dieback caused by different factors. The phenomenon results, among others, from: the occurrence of new threats from biotic factors, including caused by secondary pests and the occurrence of alien species of flora and fauna, the severity of the impact of abiotic factors and the deterioration of health (especially of conifers). The increase in the intensity of the evolution of trees is directly related to the size of the cuts contingent and will lead to a blurring of the boundary between thinning and health−cutting. It is expected that the planned size of the cuts will be implemented mainly in the thinning and accidental cuts. This requires the modification of the perception of the rela− tionship of each category cuts. We propose the order and urgency in the planning of forest use. May be supposed that the role of the clearcutting system will be limited, with the exception of some forest complexes of predominantly productive functions, dominated by poor coniferous habitats. It is recommended to use the natural regeneration in the forest management. Lack of clear boundary between thinning and final cutting will require flexibility in the accounting for the total size of cuts. The consequences of climate change will probably occur in the long term perspective. It can therefore be assumed that reasonably forest management can help to reduce their negative effects. This requires pre−emptive decisions in forest management planning and verification for silviculture, production and protection targets, and their consistent implemen− tation.

Opis:
An analysis of the occurrence of saprophagous Diplopoda and zoophagous Chilopoda 6−7 years after the hurricane of 2002 was performed on 12 research plots established for this purpose in Pisz Forest District (northern Poland) in Scots pine stands with a different scale of disturbance. Three plots were selected per each stand disturbance variant: A – severe disturbance (approx. 10% of survived trees), B – moderate disturbance (approx. 30−40% of survived trees) and F – no disturbance. In addition, we used three plots in Scots pine plantations (U) established after a complete removal of disturbed stands and soil preparation. The faunistic material was collected in 2008 and 2009 using Barber traps. Compared with the research carried out in 2004 and 2005, the occurrence of new Diplopoda species increased by 7, and their highest diversity was observed in 2009 in A variant. New millipede (Diplopoda) species were found in the post−hurricane windthrow areas, whose number, in response to the changed environmental conditions (open space with high insolation, large amount of accumulated organic matter) increased. We used the GLM, NMDS and PCA to confirm the hypothesis that myriapod assemblages can be arranged along a clear disturbance gradient: from the most disturbed pine plantations and stands to the least affected stands. The regeneration of forest ecosystems, assessed on the basis of observations of the assemblages of carabid beetles by other authors, comprises a multi−step response to the disturbance. In the case of Diplopoda and Chilopoda, such a response observed after 2009 suggests the beginning of the restoration of myriapod assemblages inhabiting the ecosystems.

Opis:
The main purpose of the study was to compare carabid beetles assemblages from recultivated and spontaneously regenerated forest of post−industrial areas. The survey was conducted in southern part of Poland in three environmental types: recultivated (afforested) dumping grounds, spontaneously re−vegetated dumping grounds and reference forests. In total, 2036 specimen belonging to 36 Carabidae species were collected. GLM analysis indicated that carabids assemblages structures (abundance, species richness, Fisher alpha index, general biomass and mean individual biomass) decreased on recultivated dumping grounds in comparison to areas with spontaneous succession and reference forest. Analysis of redundancy showed a wide variety of species composition and life traits parameters in respect to environmental types. SIMPER analysis showed that species characteristic for recultivated dumping grounds included e.g. Harpalus rufipes and Calathus erratus (small body size and herbivore strategy of feeding). C. erratus was the most dominant on spontaneously regenerated dumping grounds, while species typical for forest ecosystems included representatives of Carabus and Pterostichus sp. (brachypterous large or medium size predators).

Opis:
Coarse woody debris constitutes an important and often indispensable habitat component for a huge number of vertebrates dwelling in temperate forests. The paper collates the results of research on the impact of coarse woody debris on the functioning of the Rodentia and Soricomorpha populations. In reference to this groups of vertebrates, the subject has been well−documented in the North America. Nevertheless, with regard to small European mammals the issue has not yet been fully recognized. The paper constitutes a review of the available literature on the matter. The cited research revealed that coarse woody debris, in its different decomposition stages, increases the heterogeneity of a habitat. Creating unique micro−habitats for small mammals of high environmental demands, it offers refuge, reproduction site and rich source of nourishment. The abundance of coarse woody debris may have an indirect impact on a population quantity, density and functioning, including area exploitation. The authors stress the fact that in the case of small mammals, associations between coarse woody debris and population features are not universal for all species, since they tend to differ in ecological characteristics. An analysis of the available literature on the matter reveals that the current knowledge of the associations between small mammals and coarse woody debris needs to be broadened and improved. It concerns, in particular, the areas where this type of research has not yet been conducted, including European and Polish forests.

Opis:
The purpose of the strictly protected area of the Białowieża National Park (BNP) established in early 1900s, was to protect a compact block of the Białowieża forest from any direct human influence and activity. Its founders considered it a “laboratory of nature.” In 1936, five rectangular plots with a total area of ca. 15.5 ha (ca. 0.3% of the BNP) were set up for regular monitoring of stand development with regards to the initial state and variability of soil conditions. During the first 76 years of the project, a steady increase in the proportion of hornbeam and lime tree at the expense of shade-intolerant species was observed. This trend has been interpreted by the researchers involved in the monitoring of the permanent BNP plots to constitute a biodiversity-threatening development caused by preservation efforts. Such an interpretation has been widely incorporated in the public debate by political authorities and the forestry sector. In this critical article I challenge the major arguments presented by the key expert in silviculture, prof. B. Brzeziecki. My criticism is directed at the methodological approach as well as at the data interpretation.

Opis:
Przeanalizowano listy krytyczne grzybów (z wyłączeniem list porostów i grzybów naporostowych) pod kątem ich występowania w lasach i na terenach związanych z ekosystemami leśnymi (m.in. wrzosowiska, polany, łąki, poletka łowieckie, zadrzewienia) w Polsce. Wykazano, że na terenach leśnych, w szerokim rozumieniu tego terminu, występuje 8889 gatunków, co stanowi ponad 93% wszystkich gatunków grzybów w naszym kraju. Zestawiono taksony wybranych grup ekologicznych i systematycznych grzybów bytujących na terenach leśnych m.in. ektomykoryzowych (około 900 gatunków), kłębiakowych (Glomeromycota) tworzących mykoryzy arbuskularne z drzewami leśnymi (ok. 35 gatunków). Sporządzono wykaz bogatszych w gatunki rodzajów podstawkowych grzybów kapeluszowych i mikroskopijnych związanych z terenami leśnymi.
Species diversity of fungi of forest areas in Poland. The checklists of fungi (excluding lichens and lichenicolous fungi) in terms of their occurrence in the forests and in areas related to forest ecosystems (among others: heaths, glades, meadows, game feed plots, wooded patches) in Poland were analysed. It has been shown that in forest areas, in the broad sense of the term, there is a 8889 species, representing more than 93% of all species of fungi in our country. The taxa with selected systematic and ecological groups fungi inhabiting in forest areas, among others: ectomycorrhizal fungi (about 900 species), arbuscular mycorrhizal fungi (Glomeromycota) of forest trees (ca. 35 species) were summarized. List of the richest genera in species of macrofungi and microfungi associated with forest areas was done.
