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 economic development of the country is very much dependent on the development of the transport infrastructure, which is one of the main priorities of the state policy included in the planning and development documents. Ensuring a efficiently functioning transport system, primarily the network of roads, involves the need to improve the technical characteristics of existing roads or to build new sections. With the linear nature of road investments, we deal with interference in significant areas that have direct and indirect effects. The aim of the study was to analyze the impact of investments realized for different categories of public roads on the area of land needed to be excluded from forest production. The structure and area of the land as well as the number of forest superintendents transferred areas were also analyzed. The study was conducted for forest areas managed by the State Forests National Forest Holding (SF NFH). Data on the area of the transferred forest land was obtained from SF NFH units and the General Directorate of National Roads and Motorways (GDDKiA). In the years 2012−2015, SF NFH units transferred the land into the management of GDDKiA 203 times with the total area of 617 ha. In the same period, the transfer of the land ownership to local government for voivodship, county and municipal roads took place in 388 cases and covered 556.6 ha. Since 2003 (i.e when special act on road investments came into force), the area of the transferred land amounted to 282.7 ha in Toruń, 78.6 ha in Gdańsk and 558.4 ha in Poznań regional directorates of the State Forests. There was a decrease in the area of the transferred lands depending on the category of public roads, while the highest number of events for municipal roads was observed. There is a great variability in the time, number and area of property transferred to public roads.

Opis:
This paper deals with the author's research results on the current situation and future prospects concerning the value of forestry in rural development presented in various reports and papers including columns of Sylwan. Forestry forms a substantial part of the rural economy. Wood ad other forest products and their processing secure a number of jobs in rural areas increasing socio−economic stability and development. Apart from the economic aspects, forestry has a lot of non−market values. It is necessary to analyse potential economic and social benefits of forestry to rural areas and their development of both market and nonmarket values and to include those benefits in rural conceptions.

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:
Forest area in Poland is annually evaluated as a part of public statistics research. However, this information is based on land use resulting from Land and Property Register (LPR). Delays in the reclassification of afforested land, as well as the natural expansion of trees on abandoned agricultural lands, observed over the last decades, caused that information from LPR becomes unreliable. In many countries forest area is assessed within the National Forest Inventories (NFIs) based upon systematic grid of sample plots. NFI in Poland has been performed since 2005, in 4×4 kilometre grid with clusters consisting of five plots. Until 2014 measurements were made only on these sample plots which were located in forest according to LPR records. Within the 3rd NFI cycle (2015−2019) the areas fulfilling the criteria of forest definition, but located on non−forest land referring to LPR, has become the object of study. The aim of this work is to present statistical approach for evaluation of forest area using NFI cluster sampling data. Additionally, results from two year measurements (2015−2016) were analysed and compared with LPR data. Attributes of NFI plots allow to apply national forest criteria as well as the land use and land cover thresholds recommended by Food and Agriculture Organization of the United Nations or Kyoto Protocol. Our research shows that forest cover in Poland is in the range of 32.8−33.0%, depending on forest definition used, and is almost 3% higher than official LPR data (30.1%). The standard error of forest cover, based on two years NFI data is 0.44. Thus, with 95% probability the true value of this parameter lies between 31.9 and 33.7%, while country thresholds of forest definition are used. Additionally it was assessed that using the entire NFI cycle data the standard error of forest cover should be lower i.e. less than 0.3. The National Forest Inventory seems to be an appropriate tool for monitoring forest area in Poland.

Opis:
The registered parcel can be explained as continuous part of land within a subdistrict. It has to be also homogeneous legally and separated from other objects by the boundary lines. In the spatial structure of the State Forests National Forest Holding the registered parcel correspond to a forest compartment. The paper presents new approach to registered parcel definition, which can store more than one forest compartment (forest complex). In this way it is possible to create new basic area object as a base for cadastre (land registry) within the forest district. The aim of this study was to assess positioning accuracy of the boundary marker and the area of registered parcel. The measurements were conducted on stabilized boundary markers within forest complex and not−stabilized boundary markers within forest compartments. Using surveying technology the network of polygonal traverses were created. The control points for every travers line were measured by geodetic class GNSS receiver. It was assumed that all measured coordinates are free from error, so it was possible to asses registered parcel positioning errors. These errors are ±3.96 m for not−stabilized boundary markers and ±0.43 m for stabilized boundary markers. Applying the new idea, all existing forest compartments were joint into one big parcel within forest complex. The total number of parcels was reduced from 988 to 335. Based on formula [4] the area of parcels was calculated in two variants: considering their existing borders (not−stabilized boundary markers) and considering merged parcels (stabilized boundary markers). For the previous, the average error of parcel area equals to 1348 m² (26−6606, standard deviation=814 m²). In the latter variant, the average error of parcel area is much lower and equals 147 m² (5−3008, standard deviation=293 m²). The final results prove that new concept for basic area objects is justified and should be gradually implemented in the State Forests. This idea will not only facilitate forest management, but increase accuracy of borders positioning and simplify land registry as well.

Opis:
The paper analyzes the changes of forest fragmentation in the Western Pomerania region (NW Poland). The analysis was carried out basing on maps from 16th and 18th century as well as 1930s, when the forest cover in the studied area was the lowest. The historical area of forests was assessed on the basis on Hartnack utilization maps. The analysis of numerical maps was carried out in the GUIDOS program, which enables to evaluate the fragmentation of the forests through Morphological Spatial Pattern Analysis (MSPA) that describes the geometry of patches and their interconnectivity. The program calculated the forest areas classified for the seven categories according to their functions in the landscape (MSPA classes). In the 15th century the forests coverage was around 52.5%. There was a significant loss of forest area between the 16th and 18th century, and in the 18th century they occupied 24.7% of the researched area. Because of the economic changes in the country that took place after the World War II, the forest area in Pomerania increased to 33.7%. It was found that changes in the forest area in the examined period resulted in a decrease in the area classified as forest interior (CORE) and an increase in the boundary area (EDGE). Taking into account the equidistant of 1 km², the area occupied by the core patches dropped in the analysed period from 59.9% to 35.6%. At the same time the spatial isolation of many patches increased, which was reflected in an increase in the area classified as ‘islands' (ISLET). Their share in relation to the entire forest area increased from 4.4% to 23.6%. This could be particularly seen in the area of Pyrzycko−Stargardzka Plain and Choszczno Lakeland, where in the 1930s the so−called forest islands constituted the entire forest area of these mesoregions. The MSPA analysis enabled to specify forest patches classes, which can be useful for landscape characterization, including the patch and corridor model. The fragmentation of forests can be objectively assessed using GUIDOS and it can make the output results obtained in GIS programs complete.

The work presented here aims at developing cover mask for monitoring forest health in Poland using remote sensing data. The main objective was to assess the impact of using the mask on forest condition monitoring combined with vegetation indices obtained from long-term satellite data. In this study, a new mask developed from the CORINE Land Cover 2012 (CLC2012) database is presented and its one-kilometer pixel size matched to low-resolution data derived from SPOT VEGETATION satellite registrations. For vegetation mapping, only pixels with a cover ≥50% of broad-leaved and mixed forests defined by CLC2012 were taken into account. The masked pixels were used to evaluate spatial variability in eight Natural-Forest Regions (NFRs). The largest coverages by masked forests were obtained in Sudetian (65.7%), Carpathian (65.9%) and Baltic (51.3%) regions. For other forest regions the coverage was observed to be around 30–50%. Time-series of the Normalized Difference Vegetation Index (NDVI) comprising SPOT VEGETATION images from 1998 until 2014 were computed and cross-comparison analyses on ≥50% and <50% forest cover masks brought up frequent differences at a level higher than 0.05 NDVI in seven out of eight NFRs. An exception is the Sudetian region, where the data was highly consistent. Furthermore, the Mann-Whitney U non-parametric test revealed statistically significant differences in two regions: Baltic and Masurian-Podlasie NFR. The comparative analysis of NDVI confirmed that there is a need for additional investigation of the quality of newly developed forest mask combined with vegetation and meteorological data.

Opis:
The article presents a method of assessing the effect of vicinity on forest areas and provides a comprehensive procedure for distinguishing vicinities with a negative impact on forest areas. The study was carried out in four districts of Warmia and Mazury province (Pisz, Szczytno, Giżycko and Mrągowo). Diversification of land cover in the selected districts was identified using Corine Land Cover (CLC) databases for 2012. The authors used Analytic Hierarchy Process (a decision−making method) in order to assess significance of vicinity for a group of spatial forms. The main objective of this work was achieved by using OL indicator, which was developed by the authors as a measure of burden exerted on forest areas due to their vicinity. The indicator was determined for all forest areas under study. Based on the classification of the indicator, affected areas were isolated and the ones particularly exposed to negative vicinities were identified. The developed assessment procedure and method may become a useful tool in sustainable forest management. It allows to predict potential conflicts and threats to the natural environment and considerably improves the process of monitoring and protecting forest areas, which is especially important for environmental, social and economic reasons.

Opis:
The aim of this study was to assess the effects of different types of land use (forest, tillage and pasture) on soil properties, especially enzymes activity. Our investigation was carried out on 53 research plots with 11 plots in broadleaved forest stands, 12 plots in mixed broadleaved stands, 10 plots in mixed coniferous stands, 9 plots on tillage and 11 plots on pasture. The soil samples were collected from a depth of 0–15 cm after removing the organic horizon. Contents of organic carbon and nitrogen, pH and soil texture were investigated. Furthermore, dehydrogenase and urease activity were determined. Significant differences in the enzyme activity between forest and agricultural soils were observed, thus demonstrating that enzyme activity is influenced by the organic matter content of the soil. The highest enzyme activity was recorded in the forest soil within broadleaved stands, whilst the lowest activity was found in tillage soil, because tillage soil contained significantly less organic matter. High enzymatic activity of pasture soils is the combined result of vegetation type and the lack of plowing.

Opis:
In this paper, we present problems with the management of the forests acquired by the State Forests from the State Land Fund. This was particularly an issue in forest districts with a significant share of private forests, e.g. eastern part of Poland. The problem becomes more and more valid because of the latest amendment of the Forest Act in 2016. It gives the State Forests the right of the first purchase of private forests attributed to sale. They may receive forest stands that will generate specific economic problems related to care, conservation, felling maintenance, etc. These are mostly stands with typical features of private forests, resulting from abandoning economic operations, selective acquisition, as well as from the size, shape and neighbourhood of the plots. This study presents the characteristics of almost 2,000 tree stands acquired from the State Land Fund between 1992−2016 by the Siedlce Forest District (SFD), which is a part of the Regional Directorate of the State Forests in Warsaw. SFD has low forest cover (18%), a strong fragmentation of forest complexes and a very large share of private forests (over 75%). The analysis was based primarily on the descriptions of forest stands and the quantitative and qualitative characteristics, presenting at the same time the problems that SFD has with conducting rational forest management in acquired plots. The current status of the forests transferred from the State Land Fund was assessed as unsatisfactory. The main problems in local conditions are: (i) inadequate fixation in acquired parcels next to private forests (difficulty in locating treatments and custody over the State property), (ii) depleted tree stands, (iii) inadequate parcels (too narrow) and (iv) complications related to co−ownership of parts seized plots. The need to carry out joint−assembly works (mainly land consolidation) or to introduce land communities that would facilitate the management of these forests was demonstrated.
