Opis:
The article deals with the research on the quantitative classification of land use, which directly affects the amount of land use data collected in the real estate cadastre. For the purpose of this article, the cadastral systems of seven European countries – Austria, Bulgaria, Estonia, Spain, Lithuania, Germany and Poland – have been examined, taking into account how detailed is the classification in agricultural and forest areas. The research covered the provisions of legal acts applicable in the researched seven European countries and made available in national languages by the government bodies. The article asks the following three questions: 1) whether the researched countries adopted the same approach to isolating classes of items related to agricultural and forest areas; 2) whether the researched countries feature the same number of classes of items recorded at various levels of detail; 3) what is the percentage of the distinguished item classes of land uses in the agricultural and forest areas in relation to all of the distinguished item classes at all the levels of detail. The conducted research can be used as a material supporting works consisting of the modernization of the functioning of land registration in the real estate cadastre in Poland.

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:
Every year official data on forest area in Poland is published by the Statistics Poland. Some of this data is based on land use information contained in the Land and Property Registry (LPR). The aim of this study was to examine compliance between forest areas obtained from official land use maps and from aerial photos. Another purpose was to investigate the impact of forest complexes fragmentation on the accuracy of forests area evaluation, using land use data. The Łódź voivodeship was selected as the study area and 280 sample plots (1 km2) were established in systematic 8×8 km grid on aerial photos. Forest areas were manually inventoried using GIS software and compared with LPR maps. In the next step inventoried forests were combined into complexes using spatial analysis. The results from this study demonstrate that 3,4% of the Łódź voivodeship is covered by forest vegetation on lands not recorded as a forest in the LPR. Therefore real value of forest area is possibly higher than those based upon data published by Statistics Poland. Additionally, the part of lands with forest vegetation not recorded as a forest in LPR in total forest area has a statistical relationship with forest complex fragmentation. Much of inventoried forest complexes (41%) officially are not considered as such because of different land use record in LPR. However, our research shows that most of them (given area not the number of objects) is located in forest complexes partly recorded in LPR with correct land use record.

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 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.
