Opis:
The main role in forming the so-called small landscape retention in the Wielkopolska region is ascribed to the extent of afforestation of a given area – the size of the afforested surface in a catchment species composition and age structures of the stands. Non-climatical, physiographical parameters infl uence water storage capacity in a modifying manner only, nevertheless essential. We can say that they qualify potential water storage conditions. Working from the above-mentioned premises, the original method of potential water storage coeffi cient estimation for the Zielonka Forest Landscape Park has been formulated. The idea of the method is as follows – for each elementary area exclusive potential water storage coeffi cient is assigned. The potential water storage capacity of forested areas of the Zielonka Forest Landscape Park is characterized by relatively signifi cant spatial variability. Spatial distribution of potential water storage coeffi cients for the Zielonka Forest, obtained by herein described method, should be the basis for guidelines as far as water management is concerned in the plans of forest management or for the general land use planning.

Opis:
We analysed quality of water from the intakes in the Myślenice Forest District (S Poland). 8 springs were selected: 4 were located in the Natura 2000 area on the Mt. Polica and another 4 originated from the Harbutowice surroundings. Additionally water from 3 places on streams was gathered: 2 points were located in the ‘Las Gościba’ nature reserve and 1 in the water intake for the residents of Sułkowice municipality. Water samples were collected at the beginning of each month in the year 2016. The water temperature and flow rate were measured in the field. The hydrogen ion activity (pH), electrolytic conductivity (PEW) as well as the content of NH4+, Na+, K+, Ca2+, Mg2+, Cl–, NO3–, SO4 2–, PO4 3– and F– were determined with Dionex 5000 ion chromatograph. We also marked the content of P, K, Ca, Mg, Na, Fe, Zn, Mn, Cu, Cr, Cd, Ni and Pb using the ICP−OES emission spectrometer. All analyzes were carried out in the Laboratory of Geochemistry of Forest Environment and Areas Designated for Reclamation of the Forest Faculty of the University of Agriculture in Krakow. Water quality classification was made due to the tested properties in accordance with Regulation of the Minister of the Environment of 21st July 2016 on the classification of the state of surface water bodies and environmental quality standards for priority substances. The study confirmed differences in electric conductivity and the content of NH4+, SO4 2–, NO3 – due to the development of alimentation areas and the location of water collection.

Opis:
Techniki zautomatyzowanego rozpoznawania obiektów są wskazywane jako jeden z najważniejszych elementów rozwoju technologicznego w geoinformacji. Szczególnie dotyczy to praktyki, gdzie wymagana jest wysoka efektywność stosowanych metod połączona z dobrymi rezultatami analiz. Artykuł przedstawia istotne możliwości i zalety, powstałej na przełomie XX i XXI w. analizy obiektowej, w zakresie prowadzenia analiz przestrzennych obszarów leśnych. Metoda ta stanowi jednocześnie rozbudowane narzędzie analityczne, kontrola którego wymaga wysokiego poziomu wiedzy z zakresu teledetekcji i przetwarzania obrazów oraz umiejętności interpreteacji wyników. Główną tezę artykułu stanowi pytanie: Czy i w jakim zakresie metoda ta może zostać wykorzystana w praktyce leśnej? Wnioski nie są jednoznaczne, gdyż metoda ta znajduje się na etapie intensywnego rozwoju, co oznacza istotne niedostatki metodyczne. Jednocześnie niektóre jej elementy mogą być bardzo użyteczne.
Automated object recognition techniques are identified as one of the most important elements of the technological development in geoinformation. It is particularly true in practice, where high efficiency of the methods is required combined with good analysis results. This paper presents significant opportunities and benefits of the late-century analysis of the object regarding spatial analysis of forest areas. This method is also a complex analytical tool, the control of which requires a high level knowledge of remote sensing and image processing and the ability to interpret results. The main thesis of the article is the question:Whether and to what extent this method can be used in practical forest management? Conclusions are not clear, since this method is at the stage of intensive development, which means significant methodological shortcomings. At the same time some of its elements can be very useful.

Opis:
Several studies discussed a disagreement concerning forest extent in Poland between land cadaster and status on the ground. The aim of the paper was to assess the actual forest extent in Poland based on an existing spatial datasets such as: Digital Forest Map (covering explicitly the State Forests), Topographic Database, Database of Parcel Identification System, High Resolution Layer (Copernicus Land Monitoring product based on classification of satellite data) and National Forest Data Bank. The geospatial data analyses were preceded by an accuracy assessment of the available datasets, which allowed to assign weights to each of the dataset. The result of this project was the actual forest extent map, which refers to the national definition of forest as defined in the Forest Act of 28 September 1991 (forest by definition is a homogeneous area of 0.1 hectares). This includes all forms of ownership forests and areas that are forested, but officially recorded as non−forest. Moreover, the map of the forest extent under the Kyoto Protocol, including areas that meet the criteria of actual forest extent map and additionally forest areas designed or used for housing, recreation, infrastructure, and other industrial and agricultural areas (e.g.: permanent crops – orchards) were determined. The results confirmed that the actual forest extent is higher by almost 800 thousand hectares then the official statistics provided by the Central Statistical Office of Poland. According to the official statistics forest in Poland covers 29.4% of the country, however this study revealed that 32% of the country, considering the national forest definition, and 33.5%, considering the forest definition under the Kyoto Protocol, is occupied by forest. It showed the need for the land cadaster update. Precise information on spatial distribution of forest extent is crucial for the national purposes i.e. reporting, implementation of the National Afforestation Program and also for the international commitments under the climate convention to determine the accurate forest carbon content and carbon dioxide sequestration.

Opis:
The paper analyses the possibilities of using the forest soil descriptions included in the forest management plan to draw up an initial characterization of the area in terms of their usefulness for the forest road building. That kind of data may be used in the planning of forest road network in preliminary location concept of road sections. Knowledge in the subject of the spatial distribution of ground with specific physical properties enables us to offer such options, that are likely to ensure the stability of built facilities and also lower costs of implementation and operating as well as reduce the environmental costs of the investment. The paper shows the possibilities and ways to determine the basic characteristics of the ground, such as: the type of ground, filtration coefficient and vulnerability to frost heave. Forest soil descriptions based on macroscopic studies should be regarded as insufficient. Use of the soil data is possible and gives the desired effect only when the results of the grain size analysis can be used. On the basis of these data, classification of the ground can be performed and one can determine the basic indicators of the suitability of the tested materials. We used twelve soil samples with the diverse texture (10−89% sand, 7−83% silt and 4−29% clay). On the basis of complete pedological data collected in accordance with the recommendations of the Forest Management Instruction, it was possible to classify the material in terms of engineering and calculation of relevant indicators and characteristics. It should be noted that this is the initial characteristics of the soil and as such it is not a substitute for detailed research required for the execution stage of the project of specific road sections.

Opis:
The paper presents selected applications of the geostatistical methods for remote sensing studies of forest ecosystems. The texture of the remote sensing images of the forests can be highly complex, but at the same time it is very useful for interpretation of these images. We explored differences on semivariances calculated from transects of the Landsat TM images associated with images of young, middle−aged, old, and natural versus planted stands, as well as compared semivariances for loblolly pine (Pinus taeda L.) and longleaf pine (Pinus palustris Mill.) in Georgia, USA. We analyzed the imagery data in conjunction with ground measurements. The results showed that in spite of the relatively low Landsat TM resolution (30m), the semivariances might give useful additional information about the above−mentioned classes. The semivariances for loblolly pine depend on the age as well as on the origin of the forest stand (natural vs. planted). On the other hand, because of the low−resolution, the classical parameters of a range of semi−variances are rather difficult for classification. However, we found important differences for sill values as well as for semivariance values for the distances of a few lags. These parameters seem to be useful for forest stand discrimination. Significant differences were also found between semivariances calculated from loblolly pine and longleaf pine stands.

Opis:
Sustainable forest management, the leading topic in forest and environmental policy since the 1990s, has required an appropriate tools for both clarification of general principles and measurement of its progress. Many of indicators developed for these purpose are based on forest area. However, definitions of forest are not compatible, especially on national and worldwide scale. Definition of forest applied by FAO refers to crown cover and land use, while definition adopted for reporting under Kyoto Protocol refers only to the occurrence of trees. Polish Act on Forest applies the destination of land use as a determinant of forest. Paper analyses the process of forest area assessment in Poland for the purpose of national as well as FAO and UNFCCC reporting. Natural expansion of trees on abandoned agriculture land, still classified as the agriculture areas in cadastral system, was recognized as the biggest challenge of forest area assessment in Poland. Although natural succession is described by many authors, the total area subjected to this process is unknown. According to the FAO and Kyoto Protocol rules such areas should be reported as forests. As a consequence, forest area in Poland could be at least a few hundred thousand hectares higher than reported in the last assessments basing only on cadastral system. The proper classification of forests not recorded in the cadastral system would also be important challenge, otherwise between forest area on country and international level will be a huge discrepancy. But, there are some areas classified as a forest in Poland, which probably should not be included within FAO and Kyoto reporting. However, the most important topic concerns the possibility of identification of afforested areas, submitted under article 3.3. of Kyoto Protocol, basing on forest area changes between 1989 and 2012. One should recognise if afforested area is not overestimated using such approach, as a result of modification of forest definition in Poland in 1991. Additional question concerns the forest lands included into cadastral system after 1990, but afforested or resulting from natural succession occurring before that time, which currently are reported as afforestation under article 3.3. of Kyoto Protocol.

Opis:
The mainstream of remotely sensed methodology for identifying the tree stand condition is based on spectral responses registered by a multispectral sensor as a digital image. The changes in spectral properties are caused by dying leaves, needles or whole trees. In further steps, the relationship between the spectral values (radiometry) registered in a multispectral satellite image and the health condition of trees should be determined. The most frequent situation includes the one whem dying stand (sensu single tree) occupies the area of <5 m². Therefore the remotely sensed data for determining sanitary conditions of trees must be of a very high spatial resolution (e.g. WorldView2 or 3, GeoEye−1, Pleiades) on one hand and at the same time favourable for the vegetation studies, i.e. utilizing suitable spectral bands and be of low acquisition cost (e.g. RapidEye, LANDSAT−7, ETM +, LANDSAT−8 OLI). Thus a compromise between spatial and spectral resolution should be found to answer the question at what resolution it is possible to clearly separate the damaged tree. The scope of the research included testing of selected methods of satellite image processing and analysis in terms of defining the optimal spatial resolution, which was performed on simulated images obtained for the area of the Beskidy Mountains (S Poland). Pixel size on simulated images was downgraded to the size corresponding to the currently functioning satellite systems. Consequently the obtained material for comparison was free from influence of external factors such as the differences in: time and weather conditions, the geometry of satellite image acquisition, light at the surface of the treetops and phenological vegetation. For each image we used vegetation indices (NDVI and GDVI) and supervised classification. These tests and the obtained results allowed to draw conclusions about the optimal satellite image resolution that can be used to detect damaged or dead stands.

Opis:
The purpose of this study was to present the possibilities of using available Volunteered Geographic Information (VGI) created by the users of OpenStreetMap program and sports applications such as GPies.com or Endomondo to monitor the traffic in the forest area. In addition, areas where, due to high traffic, potential conflicts between different user groups may occur, were marked out. The research area covered two mountain forest districts located in the Sudetes Mountains: Szklarska Poręba and Świeradów, which due to their tourist values and an extensive network of hiking and cycling trails arouse society’s interest. In the area, 2896 unique activities divided into cycling, running and hiking were registered. It was shown that 7.3% of the length of routes used by pedestrians, 13.6% of the length of routes for runners and 11.0% of the length of routes for cyclists are characterized by high intensity of traffic, while 30.3%, 28.4% and 37.7% of routes for the indicated groups, respectively, are characterized by medium intensity of traffic. On other routes, low intensity of utilization was observed. Existing hiking and cycling trails were pointed out as the most frequently used routes. The specially designed bicycle routes, the so−called ‘Single track’, located in the Świeradów Forest District, were popular among the users. The highest traffic occurred in the morning and afternoon, on weekends and in the summer months. According to the adopted assumptions, there is a high risk of conflicts between runners and cyclists at about 1.5% of the route length as well as 2.1% of the length of routes used simultaneously by pedestrians and cyclists. It should be stated that VGI data can be used to monitor traffic in forest areas and constitute one of the elements of the decision support system (DSS). A certain weakness of VGI data from the sports applications used in this study could be the lack of the possibility of creating user profiles. Consequently that causes lack of more detailed data on this subject (age, sex, etc.). The limitation in the data useage is the privacy policy, which allows downloading only such data that has been made available for public use in the application resources.
