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...
The main aim of this study was to analyze the variability of width as well as content of stable oxygen and carbon isotopes, and radiocarbon in Pinus sylvestris L. tree rings. Analysed Scots pine stand grew on the fresh mixed coniferous forest habitat type on site located in the vicinity of the power plant in Łaziska Górne (southern Poland). The combined usage of tree ring width and isotopic data allowed...
The paper aimed at comparison of remotely sensed data for forest areas in Poland. The main objective was to study how time−series of satellite data derived from NOAA AVHRR and SPOT VEGETATION (SPOT VGT) are compatible and can be useful for forest cover monitoring. NOAA AVHRR fifteen−year observations collected by the receiving station mounted at the Institute of Geodesy and Cartography were processed...
Assessment of the impact of large herbivores on young generation of trees in the protected forests can support decisions about whether to intervene in natural ecosystems (e.g. individual tree protection, animal culling) or not. A study on the condition of forest regeneration, including the assessment of the damage caused by deer, was performed in the Gorczański National Park (GNP; southern Poland)...
In years 1970−2002, in Poland forest damage zones were distinguished within the framework of forest management works. Since 2003 degrees of stand damage have been determined. This study presents basic characteristics of the methods employed for these purposes concerning the necessity to elaborate a new method of determination of degrees of stand damage. The establishment of forest damage zones and...
More than 3000 direct observations of 5900 mooses were used to investigate the sex structure and growth of the population living in the Kampinoski National Park (KNP, central Poland). The study used data collected by the park service since 1998. To confirm the hypothesis that the random observations will accurately describe the population structure the experiment was performed with a theoretical population...
