This work is a short description of the history of forest utilisation in Poland, largely based on publications on forests and forestry, issued by the ‘Sylwan’ journal. The first publication on forest use was opened by Ludwik Plater, in which he introduces the rules of forest use with a clear emphasis on the need for new solutions that guarantee the continuity of the forest and its use. Until the mid−nineteenth...
Formulation of new forest policy and its implementation requires the use of past experiences and the enactment of many changes. Modification to the provisions of the 1997 National Forest Policy is necessary, introducing additions and corrections resulting from climate, economic and environmental changes, social expectations and international conditions. Agriculture and energy are the sectors of the...
The main aim of this research is to describe the current state of informal environmental education in several selected organizations and institutions in Poland. This work accommodates a tool for testing the quality of environmental education developed by the Swiss Foundation for Environmental Education and SILVIVA Foundation consisting of two checklists and a manual. The quality improvement criteria...
The current provisions in the EU directive, applicable to the signatories of the document, assume reaching by 2020 a share of at least 20% of energy coming from renewable sources. The EU Parliament demands changes to the current directive on forest biomass and its contribution to the use of renewable energy. The Parliament considers it expedient to increase the amount of forest biomass obtained, including...
This work presents the findings of a study concerning the variability in the density of oven-dry silver birch wood, depending on the geographical placement of tree stands, of the age and thickness of the trees, the influence of the forest habitat type and interactions occurring between chosen factors. The study was carried out on wood from trees aged approx. 30, 50 and 70 years old in 12 forest districts...
The article presents an analysis of the birch market in Poland in 2008−2012, including the acquisition (supply) of birch wood, the income structure, prices of birch wood, the structure of birch wood recipients and the volume of purchased timber. The necessary materials were obtained from the Forest Data Bank (BDL) and the State Forests Information System (SILP). The S2 wood assortment representing...
Development of innovative solutions in forestry requires also that students of forestry would understand in greater extend the complex system of changes in the environment and the way the man controls these changes. It is also another challenge (innovation?) for the forest education at all levels. At the level of university education, forestry in the first half of the XXI century needs to find appropriate...
The analysis of the sales methods and prices of the highest quality timber (wood veneer, plywood and telecommunication poles) was based on the data obtained from the General Directorate of the State Forests covering the period 2005−2009. They were supplemented by the data on sales, prices and revenues from sales, auctions and submissions obtained from the Regional Directorates of the State Forests...
The paper analyses the amount of cut, the assortment and species structure of the current domestic market for timber of the highest quality classes (wood veneer, plywood, telecommunication poles) in Poland in years 2005−2009. Oak and beech are the main source of material for the production of veneer in Poland. Sales of oak veneer in 2005−2009 amounted to 17,502.9 m3 (35.8% of the total sales of assortment...
The variability of selected ratios characterising the dimensions and shape of silver birch wood fibres was determined based on the site where the trees grow. Two sampling areas were selected, located in the Biała Podlaska Forest District in eastern Poland. Samples for testing were taken from trees approx. 45–50 years old, growing on a fresh broadleaved forest site and on a fresh mixed broadleaved...
The aim of the research was to determine the habitat−related variation in the selected structural and physical− −mechanical properties of silver birch. Two sample plots were established in the territory of the Biała Podlaska Forest District in eastern Poland. Samples for measurement were taken from the plots with trees aged 45−50 years growing in the fresh deciduous (Lśw) and fresh mixed deciduous...

Paper evaluates the conditions that affect the functioning of the timber market and its role in the development of forestry and timber industry during the ninety−year−history of the State Forests. Four periods were distinguished, which, according to the authors, correspond to the key stages of development of the Polish State: the interwar period (1918−1938), the period of the Second World War (1939−1945),...
