Opis:
The article is a continuation of research on the relationship between forest habitat type and economic aspects of forest management. It assesses the impact of forest habitat types on reforestation costs. As a part of the implementation of the assumed work objectives, economic activities related to afforestation were identified. The research was carried out using the passive experiment method. The research was of registration and observational character. During the acquisition of the necessary data, there was no interference in the forestry work. The costs were analysed in three categories: total costs, tangible costs and intangible costs. Research conducted on the basis of source data obtained from 629 forest plots with a total area of 1100 ha. Based on the results of the research, it was found that the type of forest habitat significantly differentiated all the analyzed costs of reforestation. The forest habitat type differentiated material costs (48%) to a greater extent than intangible costs (43%). In addition, reforestation of deciduous forests has been proven to generate higher forest renewal costs than coniferous forest habitats. The costs of forest regeneration in forest habitats were higher than the costs incurred in coniferous habitats. Information on differences in forest management costs in relation to forest habitats can be used in further research on the forest management support system. The presented research contributes to the development of work on building economic models of the stands. These models must take into account not only the general economic aspects, but also the natural aspects of the forest that affect financial flows related to forest management.

Opis:
Integrating the economic aspects of forest management (cost) with ecological elements of timber production (habitat type) significantly contributes to a better understanding of forest growth and utilisation. The type of silvicultural treatments and forest habitat types determine number of economic activities carried out in the stands and have an important impact on the associated costs. The aim of the study was to describe the impact of silviculture treatments and types of forest habitat on unit timber harvesting cost. We summarised the cost of timber logging depending on the harvest practices and types of habitats. In total, costs of treatments performed on the 2.5 thousand ha area were analysed. Obtained results were combined in relation to average unit costs of raw timber logging from individual habitats and silviculture treatments such as late cleanings and thinnings. The studied impact was assessed with standard deviation (SD) based on the assumption that the higher its value, the more important role of silvicultural treatments and forest habitats in defining the cost of raw timber harvesting. Our study showed that both factors (type of forest habitat and silvicultural treatment) had an effect on variability of timber logging costs. Comparing deciduous and coniferous habitats, higher costs were reported for the latter one. The highest unit cost of timber logging was found on the fresh coniferous habitat, while the lowest on the wet mixed forest. Moreover, the highest cost was reported for timber raw material harvested from late cleanings and the lowest from late thinnings. SD of the average cost of timber harvest ranged from 12.67 to 13.53 PLN depending on the silviculture treatments and from 0.68 to 2.39 PLN depending on the forest type. Our findings are important preliminary steps in broader study regarding revenues generated from forest stands growing on different habitats. Eventually it would help in assessing the profitability of economic activity that depends on environmental conditions of forest management.
