Opis:
Fungi are among the most important organisms on earth, and they are essential components of terrestrial ecosystems. Their reproductive structures are strictly dependent and affected by environmental conditions, and community dynamics over time and space may be indirect indicators of the health status of forests. We combined macrofungal biodiversity indices in eight Mediterranean forests in Italy and surveyed 160 plots by standardized surveys, to evaluate the role of macrofungi as early predictors of change in the forest structure. The results show that indices of fungal diversity are influenced by geographic and floristic conditions, and inter- and intra-annual temperature and rainfall fluctuations affect the formation of fungal fruiting bodies. These findings suggest that environmental changes could be reflected by macrofungi, and conservation initiatives should consider the pivotal role that fungi play in biodiversity monitoring.

Opis:
Fires in natural ecosystems cause catastrophic consequences on a global scale. These fires are caused by landscape-transforming factors, which include dust and gas pollution of the atmosphere, destruction of forests and living organisms, pollution of ecosystems with dangerous toxic compounds and heavy metals. The aim of the presented research is to investigate the influence of ground forest fires on the concentration of mobile forms of heavy metals in different soil horizons. Sampling of soils of pyrogenic origin was carried out from 4 plots according to operating standards on the territory of Rava-Rusky forestry near the village of Lavrykiv, Zhovkva district, Lviv region (Ukraine). Soil sampling for investigation of migration of heavy metals was carried out taking into account the number of years spent after burning of meadow vegetation and forest litter. The most contaminated with heavy metals is site #2 (completely burned out 2 years before the experiment). There is a significant accumulation of cadmium in edaphic horizons (0.31 – 0.66 mg/kg), the value is close to the maximum allowable concentrations for soils (0.7 mg/kg). Also in this area the highest content of mobile forms of nickel (1.52 – 2.80 mg/kg) was detected, while the maximum allowable concentrations for soils is 4 mg/kg. The lowest content of heavy metals is in the site #1, which was exposed to fire long before the start of monitoring – 3.5 years. Here the values of mobile forms of heavy metals are close to the background. Vegetation in burnt areas at the first year of post-pyrogenic development is characterized by spontaneous single species. In 2–3 years it is characterized by a group arrangement. Complete natural overgrowth of the burnt area (natural vegetative reclamation) occurs 4–5 years after combustion. Monitoring the impact of ground forest fires on the concentration of heavy metals in edaphic horizons is important in terms of environmental renaturalization and the development of preventive measures for forest fires and fires in natural ecosystems.

Opis:
Extension of the forest area in Ukraine is one of the indicators confirming achievement of the goals of sustainable development. Therefore, the issue of protection, restoration and rational use of forest ecosystems is rather actual. The process of self- afforestation taking place on agricultural land, which are not used according to their intention because of their investment unattractiveness, due to lack of funds or other reasons, and thus, they are self-sown with forest plants, is one of the ways of the forest- covered area extension in Ukraine. There is no reliable information on the number of land plots with self-sown forests on agricultural land. Therefore, it is expedient to make inventory of them by using the tools of satellite remote sensing and field surveys. The author of the work suggests a conceptual model of planning the use of agricultural land with self-sown forests on the base of the inventory data. To make the best-possible decisions on the use of the land plots with self-sown forests, at the local level it is important to determine the rational direction of the self-sown forest use in the process of spatial planning on the base of the data of analysis of the soil and plant cover layer quality. Therefore, it is recommended to make zoning of the land by the kinds of land use (agricultural, forestry, recreational, nature protection). Basing on the zoning data and considering the potential ecosystem benefits from forests, it is necessary to develop measures on the self-sown forest use and protection.

In the era of dynamic climate change, it is important to have knowledge on the interactions between climatic factors and processes occurring in the soil environment. The present study aimed to determine how slope aspect and altitude above sea level influence carbon and nitrogen accumulation and dehydrogenases activity of forest soils. The study was conducted in the Beskid Żywiecki in the south-facing part of Poland. Soils of the same texture, with similar vegetation species composition, in different altitude variants (600, 800, 1000 and 1200 m above sea level) and different north-facing and south-facing slope aspect were selected for the study. For each height and slope aspect variant, samples were collected from the surface horizons of soils for further analyses. The basic chemical properties and dehydrogenases activity of the soil samples were determined. Carbon and nitrogen stocks in the surface horizons of the soils were calculated. The analyses confirmed the influence of location conditions on the carbon and nitrogen stocks in mountain forest soils. The stock of carbon and nitrogen increased with the height up to 1000 m a.s.l. In the soils at the highest altitude, the reserve of carbon and nitrogen decreased regardless of the slope aspect variant. There were no statistically significant differences in carbon and nitrogen stocks between slope aspect variant. The highest dehydrogenases activity was associated with the organic horizons of the soils at the lowest altitude in height gradient. In our study, higher dehydrogenases activity was observed in the north-facing slope soils, and this finding can be explained by more stable thermal conditions.

Opis:
Climate change is a major threat to mangrove ecosystems worldwide but particularly those in arid regions that exist near the limit of tolerance to extremes in temperature, precipitation, and salinity. Here we examine Persian Gulf arid mangrove ecosystems from the Nayband and Mond Protected Area in the south-west region of Iran to determine the ability of tidal mangrove forests to respond to rapid urban and industrial development, sea-level rise (SLR), and temperature and precipitation changes. Sea level has been rising by approximately 4 mm yr−1 in this region and might be intensified by subsidence on the order of 1—2 mm yr−1 due to natural phenomena as well as anthropogenic activities associated with fluid extraction. We use remote sensing along with statistical analysis to effectively monitor mangrove area changes over 60 years and infer responses to past environmental trends. Our spatiotemporal analysis demonstrates expansion in some areas and reduction in others. NDVI (Normalized Difference Vegetation Index) results indicate that Nayband mangroves are healthy and expanded between the years of 1990 and 2002 which could be in response to rising temperatures and above-average precipitation. However, NDVI changes after 2002 demonstrate the mangrove health and area have decreased which could be in response to industrial and urban development that occurred immediately after 1997. The natural stresses in this extreme system are been exacerbated by climate change and anthropogenic pressures as such it is essential to develop ways to reduce vulnerability through strategic management planning.

Opis:
In the face of growing urbanised areas, the presence of forests and their appropriate shaping is a key challenge for contemporary urban planning. The importance of forests is largely identified with natural, economic and social functions in non-urban areas; however, forests are of vital value in urbanised areas. This article explores young Polish urbanites’ awareness of the role forests play, and submits diagnoses of the forests multidimensional benefits and their functions in Poland’s urban areas. Moreover, the research is based on the premise that the management of urban forests must ultimately lead to the satisfying of social needs. Based on empirical research, the perceptions of the value of urban forests as assessed by young people (students) in the Śląskie Voivodeship are presented, leading to the authors’ postulation that urban forests are underestimated resources. Furthermore, the study suggests that young Poles do not recognise the multi-beneficial aspects of urban forests; and the authors indicate feasible directions for local policy to achieve sustainable development. The final statements argue that in the face of serious threats to the functioning of Earth’s ecosystem, a campaign for the presence of forests and green spaces in cities is necessary.
W obliczu rosnącej powierzchni terenów zurbanizowanych obecność lasów miejskich i ich odpowiednie kształtowanie jest jednym z kluczowych wyzwań dla współczesnej urbanistyki. Znaczenie lasów utożsamiane jest głównie z funkcjami przyrodniczymi, ekonomicznymi, czy społecznymi na terenach pozamiejskich. Jednocześnie tereny leśne niosą istotną wartość na terenach zurbanizowanych. W wielu krajach obserwujemy rosnącą świadomość znaczenia lasów dla zdrowia fizycznego i psychicznego mieszkańców oraz prawidłowego kształtowania się relacji społecznych. Sąsiedztwo lasów pozytywnie wpływa na jakość życia mieszkańców miast. Interesujące poznawczo jest na ile mieszkańcy miast w Polsce mają świadomość roli lasów w miastach oraz w jaki sposób z nich korzystają. W artykule dokonano diagnozy wielowymiarowych korzyści funkcji terenów leśnych na obszarach miejskich. W oparciu o badania empiryczne przedstawiono percepcję wartości lasów miejskich w ocenie młodego pokolenia województwa śląskiego (studenci). Na podstawie przeprowadzonej analizy roli lasów autorzy zaprezentowali kierunki wsparcia polityki lokalnej ukierunkowanej na zrównoważony rozwój. Zdaniem autorów, w obliczu poważnych zagrożeń dla funkcjonowania ziemskiego ekosystemu niezbędna jest kampania na rzecz obecności lasów i drzew w naszych miastach.

Opis:
Mitigation and adaptation are the main strategies to address climate change. Both of them are interrelated instruments and key elements of an integral approach to tackle the phenomenon. This interrelation is particularly strong in the land use sector, an area in which practically any policy has a significant effect on the goals of both strategies. Yet, in practice, mitigation and adaptation are treated as two different instruments. A poor understanding about the interactions between the mentioned strategies remains as a barrier to implement the integrated approach. To contribute to fill-in this knowledge gap, a hypothetical ecologic-economic system simulated under deep uncertainty was used to test environmental and welfare implications of different policy configurations. Taking the unregulated economy as a benchmark, the outcomes of the mentioned interventions were classified as synergies or different forms of trade-offs. Results indicate that measures based on internalization of externalities overcame monetary compensation schemes. Moreover, when externalities were corrected, synergies were more frequent and associated to higher environmental and welfare gains. Furthermore, the policy configuration that exhibited best synergic properties was an intervention integrating mitigation and adaptation measures. This indicates that synergies may be more accessible than previously considered, however, current policy approach and incentives may not be the best tools to trigger them.

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 presents a comparative analysis of social preferences related to running in the forests of Poland and the Czech Republic. The preferences were determined on the basis of a questionnaire distributed in 2016 via social media among people interested in running in in both countries. The survey covered 346 people over 18 years of age in Poland and 294 people from Czech Republic. The questionnaire included questions such as: the frequency of running in the forest, the preferred season for running and average number of running kilometers in the week and the views on advantages and disadvantages of running in forest areas. The results show that there is quite a lot of differences between the preferences of respondents from both of the analyzed countries. Statistical analysis was carried out using the chi−square test. The observed differences relate mainly to the choice of season for running in forests, the frequency of running in the forests, average distance covered in a week and the views on advantages of running in forest areas. The most preferred season for running in Polish forests was summer, then spring, while in Czech ones it was exactly the opposite. Most respondents in Poland run in the forest several times a week, whereas in the Czech Republic – several times a month. The most frequently mentioned advantages of running in Polish forests were: contact with nature, clean air, landscape – pleasant environment. In Czech forests among the most frequently mentioned advantages of running were: contact with nature, good quality surface and clean air. Subsequently, the respondents pointed to the lack of traffic control infrastructure, and lack or a small number of other recreational people. Among the disadvantages of running in the forest, respondents in both counties mentioned mainly: the presence of tick and hunters. Other factors limiting the comfort of running in the forests included: uneven road surface or problems with phone connection. Only the views on the subject of the attractiveness of the forests for running and disadvantages of running in forest areas were not significantly important.

Site and situation specific assessments of ecosystem services are crucial to sustainably conserve and manage the Chilmo forest. In this specific study, an attempt has been made to identify how local communities depend on Ecosystem services and on other stakeholders involved in sustainable forest management. The study triangulated primary data collection methods such as field observations, household surveys and key informant interviews. Secondary data was also used to support and verify the primary data. SPSS version 20 software and Microsoft excel were then applied to describe the socioeconomic characteristics of the study population’s households. Data collected through discussions and observations was analyzed qualitatively. Four forest ecosystem services (provisioning, regulating, habitat and cultural services) were identified in the study area. Even though agriculture is the main economic activities, sample respondents earn money from diverse sources such as from homestead, wood lots, honey production, petty trade and from the selling of timber and non -timber forest products, from forest dividends and other forest related employment. Chilmo forest, on average, contributes more than a third of total annual income of the sample households. Surprisingly, almost all sample respondents participate in fuel wood collection, both for household consumption and market. Similarly, fuel wood collection generates the highest income, compared to other activities, because fuel wood is the sole source of energy in the study area. Therefore, provisioning services are the main source of livelihood and subsistence incomes for local communities. The findings greatly contribute towards the management of the Chilmo forest and will be used as input for further valuation work.

Opis:
The Białowieża Forest (BF) is in many respects an exceptional object, of a great importance for nature protection and forest management, at the international scale. The BF plays also a key role from the point of view of regional development and welfare of local community. In the last period, a big threat for multiple values of the BF has arisen, as a result of enormous bark beetle infestation, which started in 2012 and has killed 1.4 million m3 of spruce trees. In the paper, first, a brief overview of the general history of the BF and an account of long−term human impacts on its functioning and structure is provided. Next, the history of bark beetle infestations in the BF is analysed. It is shown that, in the period 1992−2007, the average volume of spruces killed by bark beetle amounted on average to 20,000 m3 of wood annually. During that period practically all dead trees were removed from the forest by means of salvation cuttings. Starting from 2008, more and more trees infested by European spruce bark beetle were left in the forest, in a result of a pressure exerted by environmental groups. In 2012, Minister of Environment decided to reduce the allowable cut, determined in forest management plans elaborated for the managed part of the BF, from 107,000 to 48,500 m3/year. This decision, along with several other regulations and restrictions, made in practice impossible to stop the development of a current bark beetle infestation, which started in 2011 and intensified during the next 6 years (solely in 2016 bark beetles killed 480,000 m3 of spruce trees). In the paper, the most important implications and consequences of the current situation are briefly summarized and discussed. A special attention is given to the problems concerning: 1) protection of Natura 2000 species and sites (endangered by bark beetle outbreak), 2) a negative influence of large amounts of spruce deadwood on forest soils, 3) threats caused by pathogenic fungi, 4) question of public safety, 5) fire hazard, and 6) economical dimension. The legal and socio−economical foundations of the functioning of Hajnówka, Browsk and Białowieża forest districts comprising the managed part of the BF, as well as their most important environmental and social consequences are discussed too. Among others, it is indicated that, under current conditions of the BF, human intervention plays a key role in maintaining stable and compositionally diverse woodland communities. Finally, several suggestions and recommendations are provided, aimed at, in the short term, breaking off the current bark beetle outbreak, and, in the long term, at maintaining a multifunctional character of the BF and its ability to provide all important ecosystem services on a sustainable basis.

Opis:
The paper presents the ideas of sustainable development with regard to the specific forest issues and management of its resources. We consider two main directions of forest use, which have the greatest impact on the condition of forest environment, i.e. logging and recreational use of the forest. This confrontation shows how effective the instruments of sustainable development are in collision with, on the one hand, the pragmatic−economic issue of profitability and a specific profit from logging, and, on the other hand, with the autotelic tourist exploration of the forest. The aim of the paper was to discuss selected aspects of sustainable forest use with regard to the sustainable development program and to identify problems, which modern forest management (forest utilisation) faces as a result of society’s expectations and the possibilities of today’s forestry in Poland. The example of Poland shows that there is a full understanding of the need to preserve the forests in the landscape, which was reflected in the form of legal acts and adopted international regulations for sustainable forest management (most forests in Poland have PEFC and FSC certificates). However, considering forest use as one of the main branches of forest management, there is still a large deficit of pro−ecological logging technologies in Poland, especially from difficult mountain areas (about 150 cableways missing), which is largely due to economic factor. The other problem of sustainable forest use in Poland is still low social awareness of the consequences of negative human impact on the forest ecosystem, which is manifested, i.e. littering in forests. Garbage is left both during leisure in forest as well as brought in larger quantities creating so−called wild dumping sites frequently containing also hazardous waste. Another problem of contemporary forest use is the maintenance of durability of forest ecosystems in recreational and tourist areas, especially protected areas, and above all in national parks, most of which in Poland have a forest character. The scale of threat to forest sustainability is incomparably higher here than in economic forests, which results from the large number of visitors in the national parks.

Opis:
In Poland, the stormy discussion on the future of the Białowieża Forest has been ongoing already for a long time. The disputes are mostly focused on seeking answers to two questions: how to protect these unique forest ecosystems and whether forest management threatens their naturalness. The discussion has grown stronger after the recent, enormous outbreak of Ips typographus in the Forest. The Białowieża Forest has been managed for years with no negative effect. However, antagonists of foresters blame forest management for degradation of the Forest’s ecosystems, which is caused by favoring the economic value of timber expected to be harvested in keeping with the management plans of 3 forest districts located in the Białowieża Forest. At any rate, such assumption, has nothing to do with reality. During this discussion the idea to extend the national park for all the Białowieża Forest revived. In this paper, we reviewed the economic, social and ecological dimensions which should be taken into consideration before making a decision on extending the Białowieża National Park. It should be underlined that the Park’s area is already under the strict protection; furthermore, 2/3 of the area of neighboring managed forests are under legal protection (the nature reserves, NATURA 2000, the so-called reference forests, etc.). All things considered, we cannot find any reasonable purpose (ecological, financial or social) for expanding the Park’s area from 10 500 ha (present status) to 62 500 ha (after extension). Also, we are convinced that sustainable forest management conducted in managed parts of the Białowieża Forest, which comprises the fulfillment of all forest functions and services, should not be perceived as a threat to naturalness of the Forest’s ecosystems.

Opis:
Studies of forest ecosystems enable gathering important information on the natural environment the development of which is more and more disturbed by the global climate change. The current research on the ecosystem functioning provides data that may be of much value for future analysis and prognostic studies. Modern measurement techniques used in the forest research have a significant influence on the increase in the database resources, especially those concerning the spatial data. Big data requires the use of advanced analytical technologies, such as data warehouses, computer clusters or cloud computing. Consequently, cooperation of specialists from various scientific disciplines, including forestry, geography, climatology and computer science, has become increasingly necessary. The IT system of the Forest Research Institute (FRI) was modernized within the framework of the Operational Programme – Innovative Economy 2007–2013. Its functionality allows integrating, storing and analyzing ever more big databases from dispersed sources. The idea of open access to data is realized by the FRI mainly through publication of research results in domestic and foreign scientific journals, in specialized information services and on scientific portals. On the other hand, open access to raw data still raises a lot of concern and controversies in the scientific community, especially in the context of copyright infringement.

Opis:
The central part of the Silesia Park in Chorzów was designed as a forest refugium. Now this area of 200 ha is under pressure. Many trees have been cut down for the safety of park visitors. The forest is of significance for people who prefer walking and relaxation far from urban noise and park events. In May 2015, a pilot valuation survey of the forest refugium was conducted using the contingent valuation method (CVM). Respondents were asked if they would be willing to pay a local tax established in consequence of a referendum. Almost half of the respondents did not support implementation of this tax in surrounding towns. The maximum annual tax amount declared by the respondents was 100 PLN, the annual average was 34 PLN and the annual median was 20 PLN. Taking into account the number of residents who totally rejected the tax proposal, the average annual amount was 17 PLN. The forest refugium in the Silesia Park is appreciated by naturalists but is not often visited by the public. This forest area is probably not sufficiently important for the residents to introduce a local tax. The aim of this article is to show restrictions of the use of the CVM method.
Centralna część Parku Śląskiego w Chorzowie została zaprojektowana jako leśna ostoja. Obecnie ten 200-hektarowy obszar jest poddawany presji. Wiele drzew zostało wyciętych dla bezpieczeństwa odwiedzających, ale las stanowi dużą wartość dla osób preferujących spacery i odpoczynek z dala od zgiełku miejskiego oraz parkowych imprez. W maju 2015 r. przeprowadzono wstępną wycenę ostoi leśnej metodą wyceny warunkowej (CVM). Ankietowanych pytano o chęć zapłaty podatku lokalnego wprowadzonego w drodze referendum. Prawie połowa ankietowanych nie poparła wprowadzenia takiego podatku nałożonego na mieszkańców okolicznych miast. Maksymalna zadeklarowana kwota podatku wyniosła 100 zł rocznie, średnia - 34 zł, a mediana 20 zł rocznie. Po uwzględnieniu osób odrzucających podatek, średnia kwota wyniosła 17 zł rocznie. Ostoja leśna w Parku Śląskim jest doceniana przez przyrodników, ale nie jest powszechnie odwiedzana przez ludność. Ten zalesiony obszar jest prawdopodobnie za mało ważny dla wprowadzenia podatku lokalnego. Celem artykułu jest pokazanie ograniczeń zastosowania metody CVM.
