For effective forest management, comprehensive information on the condition and structure of wood resources is needed, as well as a forecast of their development and the possibility of harvest cutting in the long term. The paper objectives is to present a methodology of predicting the development of wood resources and the possibility of main cutting based on the current state of the forest. Presented...
The paper analyzes the spatial and temporal diversity of afforestation of non−forest land, with particular emphasis on land not being the property of the State Treasury, before joining the European Union and as part of subsequent stages of the Rural Development Program. Data from the databases of the Statistics Poland and from the Agency for Restructuring and Modernisation of Agriculture was used...
The article presents the standardization of costs of silviculture treatments (reforestation and afforestation, corrections and overplanting, forest tending) with the method of grouping forest districts with similar natural conditions and the ‘technological’ method. The standard costs were compared with the real costs, and the applied methods were assessed in terms of their suitability for the State...
Forest management is carried out based on the economic calculation, taking into account the principles of forest sustainability and protection. For a short period, an attempt to predict the unit’s economic situation on the basis of the analysis of the time series with a trend can be made. Appropriate exponential equalization methods were selected. When forecasting fixed costs in the new economic period,...
The article presents methods for standardizing the costs of the silvicultural treatments (renewals and afforestation, corrections and additions, tending). Our scope included the statistical determination of factors shaping the costs of selected works, elaborating methods of their standardization, assessment of these methods suitability for determining standard unit costs of selected silvicultural...
Planned forest management is carried out based on the forest management planning (PUL) operations prepared for a 10−year economic period. The economic expertise may omit a detailed organizational analysis of the company, as well as indications regarding the search for strategic solutions. The following study aims to present a method for analysing the economic consequences of forest management activities...
The State Forests, National Forest Holding, is increasingly burdened with the costs of nature protection, recreational development and certification. As a consequence, there is an increase in costs and limitations in forest management. The emphasis is also on different social and environmental functions, and as a result, income from the sale of wood becomes smaller. The aim of the study is to verify...
A prerequisite for effective forest management is a detailed economic analysis of given management determinants. In the forest district’s expenditures, next to the wood harvesting and skidding, the cost of silvicultural activities constitute a considerable share. The choice of forest management methods, including those for forest regeneration has a significant effect on the costs incurred for silvicultural...
In Polish forest management planning, the species composition of stands in a forest district is established by adding up the volumes of tree species from individual forest stands. These volumes are calculated according to the estimated share of species cover and the estimated volume of the entire forest stand. The species structure of stands in a forest district, established on the basis of such a...
Scots pine is the dominant forest tree species in Poland covering 58.0% of the forest area and constituting 61.1% of timber resources. Theoretically, all types of cuttings can be used in pine stands, but the purpose of the paper is to analyse the share of the main groups of assortments obtained from such stands with the use of: clear, group and gradual cuttings. It should be remembered that all types...
W artykule przeprowadzono analizę gminnego komunalnego składowiska odpadów zlokalizowanego w województwie podlaskim. Składowisko zlokalizowano przypadkowo, bez izolacji dna, a eksploatacja składowiska była prowadzona bez wyraźnie określonych zasad. Wykonanie trzech otworów i pobór próbek gruntu umożliwiło ocenę składu chemicznego gruntu dla wybranych wskaźników zanieczyszczeń, wykazujących wartości...
