Opis:
The old forest complex of Rzepiszew (76.81 ha of land) is located in the east part of Szadek commune. It is surrounded by arable fields and meadows. At present it is a timber forest, but forest management is based on ecological rules. 260 Vascular plant species forming 55 families have been found in this area during field research which was carried out in years 2006-2010. The identified species represent different types of growth (= life forms in Raunkiaer's terminology) Hemicryp- tophytes have been found to dominate. The flora contains plants from various ecological groups classed according to light conditions, moisture of soil, soil acidity and soil trophy. Most of them are stenotopic plants - they have a limited (narrow) ecological amplitude. The true forest species are the most valuable components of flora. Seven among them are protected by law.

Opis:
The wetland ecosystems are among the most endangered in Poland. Small water bodies situated within forest complexes are the habitat of many unique species of flora and fauna. They are also an important part of compound hydrological systems in forest ecosystems. The occurrence of more than 90 vascular plant species was noted as a result of research on plants diversity of natural pond (it is about 200 m2 in surface area) with its surroundings, which is located in Wilamów forest complex (the eastern part of Szadek commune). The list of plants includes vulnerable species such as: Nymphaea alba, Drosera rotundifolia, Nuphar lutea, Ledum palustre (endangered and protected by the law), Eriophorum vaginatum and E. angustifolium (locally rare and endangered). This natural site is worthy of preservation and establishment of “Śródleśny staw w Wilamo-wie” nature protected area is suggested. A stable hydrological regime is the most important for maintenance of biodiversity of this place.

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:
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.
