    Bieszczady Mts.
    Opis:
    This study aimed at quantitative spatial analysis of forest cover transformation in the Western Bieszczady Mts. based on two areas: Bieszczady Wysokie Mts. (from 1852 to 2004) and Baligród Forest District (from 1938 to 1996). Raster maps were created to illustrate two cover types: forest and non−forest. Using ACSII files and Fregstats 3.3 program, landscape metrics were calculated for whole landscape and both cover types. Landscape structure became simplified. Forest cover area increased with simultaneous patch number decrease and aggregation degree increase. Non−forest cover underwent inverse changes, such as area and aggregation degree decrease. Patch number change differed in both areas in relation to various processes of patch creation.

    Opis:
    The aim of this work was to present changes in the fragmentation of forest area characterised by a two−fold increase in forest cover during the last century. The Forest Area Density (FAD) indicator was utilised in order to determine the forest fragmentation for the raster analysis of numeric maps. Its calculation was made using GuidosToolbox software. The research covered 1862 km2 of a predominantly post−glacial area of the Ińsko Lakeland, located in the north−western part of Poland. At the end of the 19th century, forests occupied 273.0 km2 of this area, while at the beginning of the 21st century their area coverage increased to 612.5 km2. The observed increase in the forest cover was associated with changes in forest fragmentation, which was analysed using the FAD. When comparing the two surveyed periods on the synthetic result maps obtained by utilising the FAD method, visible changes can be seen in individual forest categories, which indicate a decrease in the fragmentation of forest areas. The use of fragmentation measures is justified because according to the data found in the literature, the recently observed increase in forest coverage in many areas of Europe does not always determine the decrease in their fragmentation. This verifies the legitimacy of using the FAD indicator in the context of ecological and economic assessments.

    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.

    Opis:
    The aim of the study was to research which wood species were used to make constructions and everyday objects in the Świętokrzyski, Rural Town, and Manor sectors of the Ethnographic Park (an open−air museum) in Tokarnia (central Poland). The objects on display are in the natural village environment. Apart from the traditional architecture there are also permanent exhibitions of furnishings belonging to people of different social classes. In all investigated sectors we found thirty five items. Wood species were determined using the macroscopic method. The Ethnographic Park archives contain residual information about wood species. Larch was the most commonly used wood species in the whole area. Other species used in the architecture include oak, pine and fir. Chairs and beds were made from pine and oak. For upright furniture, oak and less often pine were used. The other wood species used in this kind of furniture were larch, ash, beech and walnut. Kitchen utensils were mostly made from pine, poplar, birch, beech and oak. School utensils were made from beech, birch and pine. Oak, beech and birch were used in others items. Wood species used in construction and the production of everyday objects in the Kielce region from the end of the 17th century to the beginning of the 20th century. Localization and investigation into others traditional objects in świętokrzyskie voivodeship should be further discussed in the next study. Moreover, maps of tree stands from the end of the 17th century to the beginning of the 20th century should be analysed. Consideration of these aspects may help find the reason why larch was the most popular wood species in the Ethnographic Park in Tokarnia.
