    Opis:
    The aim of the study was to determine the impact an increased wood supply from the Beskid forests after natural disasters on the timber economy of the Węgierska Górka Forest District and its surroundings in the years 2004–2010. The analysis was based on the wood raw material sales recorded in the database of the State Forestry Information System (SILP). Information on the buyers’ location and their main use for the raw material were obtained through the Central Statistical Office. Furthermore, wood material buyers were classified according to the Polish Classification of Activities (PCA) based on the year 2007, using only a subjective analysis designed for enterprises and other economic units in the national economy. Changes in sales of wood material to the selected buyer groups were investigated using statistical analyses of linear trends. A Pearson’s correlation analysis verified the relationships between the buyer groups and the supply of timber assortments by the Węgierska Górka Forest District. Other studies have also shown that an increased supply of raw material in the context of natural disasters affects the types of wood buyers and their location. In addition, they have shown an increase in interest towards the purchase of raw materials among buyers engaged in the wholesale trade of wood and other non-wood producers which in turn decrease the share purchased by sawmills.

    timber quality variation
    defects
    pinus sylvesrtis
    Opis:
    The aim of the research was to determine the impact of selected habitat and age features on the qualitative properties of Scots pine (Pinus sylvestris L.). The research was carried out on forest stands from the Olesno, Wymiarki and Kalisz Pomorski forest districts (western Poland). The collected data provided information on technical and dimensional properties as well as quality classes for logs from Scots pine stands. The severity of the occurrence of seven basic wood defects, identified on the perimeter and length of the model log was identified and described. The collected data was used to determine the distribution of defect groups. For distributions of defect groups, normal distribution criteria were met. For the Scots pine assortments, the ANOVA showed that the hypothesis of the occurrence of an equal number of defects on the side of the logs in three separated classes of WA0, WB0 and WC0 of the quality of the raw material should be rejected. For the Tukey test, the results indicate that there is no reason to reject this hypothesis. The obtained p−value in this case is 0.09 for WB0 and WC0. There was no influence of the diameter of the logs and the habitat on the number of defects. Number of defect groups is correlated with the distance from the butt in Kalisz Pomorski and Wymiarki forest districts but not in Olesno. In that case the increase in the number of defect groups has its maximum in the zone of 6−8 m of the log length.

    threats to the forest ecosystem
    threats to tourists
    Opis:
    The paper presents declarative opinions of 239 tourists who visited the area of the Krynki Forest District in July−September 2013. The opinions were collected in direct interviews using of a questionnaire. The analysis distinguished two groups of respondents: 135 people (56,5%) who visited the forest district for the first time, and 104 respondents (43,5%) for whom it was the subsequent visit. We analysed the opinion of tourists on such problems as: (1) anthropogenic threats to the forest ecosystem, (2) factors constituting a threat to visitors to forest areas, and (3) forms of recreation and rest that can be implemented in forest areas. To examine the significance of mean differences between analysed groups of respondents that differ in experience and hypothetical readiness to declare the amount of WTP> 0, the Mann−Whitney test was used. Respondents considered forest fires and garbage left in the forest as the greatest threat to forest ecosystems, while among factors threatening people resting in forest areas, respondents pointed to the natural factors such as vipers, ticks and mosquitoes. Respondents considered that admissible forms of recreation and rest in forest areas are sport and cross−country races, horse riding and cycling, while ones that pose a threat to forest ecosystems, e.g. organization of mass events or bonfires and family events with barbecue, should be prohibited. No impact on differences in the opinions declared by the respondents, their tourist experience or readiness to declare the amount of WTP was disclosed.
