Opis:
The theory of sectoral economic development is evolving, as new forms of work organization and new economic sectors are created. Lack of clear definition of the economic sector makes it difficult to determine the impact of economic sectors on the development of the Polish forestry precisely. Forestry activities focus in three main sectors of the economy: agriculture, industry and services. In addition, they focus in three institutional sectors: the non−financial corporate sector, the household sector and the sector of government and in two ownership sectors: public or private one and in many co−operative sectors such as: forestry−wood, raw materials or defensive. Considering the place and the role of forestry from the viewpoint of the three−sector theory, it should be noted that most of the administrative and economic activities of the State Forests belong to the primary sector (agriculture). The industrial/manufacturing sector includes additional production associated with the wood and other forest products processing. This sector in the Polish forestry is currently neglected, but it used to be important, especially in the 1920−1930s. The tertiary sector comprises of services provided by the forestry, transport, construction and installation, training and leisure activities and others. This sector is growing rapidly and should endeavor to the commercialization of educational, recreational or defensive services, which are not currently measured. Analyzing the place of forestry among institutional sectors, we should state that forestry has the most significant importance in the non−financial corporate sector as the State Forests and forestry service companies (employing more than nine people) belong to this sector. In the household sector, there are small forestry service companies employing up to nine people and natural persons obtaining income from logging of private forests and other wooded lands. Whereas, in the government sector, there are mainly communal cities and municipal forests and traders running forestry activities in state forests of other ministries. Considering the development of the Polish forestry from the viewpoint of ownership sectors, it must be noted that since 2012 more people have been employed in the private sector and the gross added value of production has been higher in the private sector. The development of Polish, multifunctional forestry, in accordance with the principles of sustainable economic and social development, should be considered in the context of social needs and expectations, which change with the socio−economic development of the country.

Opis:
The objective of this study was to learn to what degree the afforestations affected the seasonal dynamics and changes in population abundance of Anoplotrupes stercorosus (Hartm.). The beetles were caught in traps in the Człuchowska Primeval Forest in 1998−1999. A total of 51 814 individuals of A. stercorosus were caught. The obtained results have shown that the peak activity of this beetle falls on June and September, and the optimal habitat conditions are poletimber and mature stands. A. stercorosus colonised coniferous stands growing on former agricultural lands more frequently than the same stands growing on forest lands.

The paper presents resent research results on the effect of aluminium (Al) toxicity on forest soils. It has been stated that with the present acidification level of the environment the toxic effect of aluminium compounds does not threaten the sustainability of stands. At the same time, the simulation of heavy acidification of soil environment has proved that mixed stands are more resistant to Al than pure spruce stands growing under the same conditions.

The paper describes the changes in the current annual volume increment of fir stands in the Forest Experimental Station in Krynica in 1971−2011. The research material are the results of five−fold measurements of stands on 238 control sample plots using an inventory and control method based on the statistical and mathematical system. On average, current annual volume increment in the 1970s amounted to 6.10 m³/ha/year, while in the 1980s to 8.46 m³/ha/year, in 1990s to 10.52 m³/ha/year and to 13.42 m³/ha/year in the last decade (2001−2011).

Opis:
The aim of the experiment was to compare the rehabilitating effect of three factors that may improve the degraded and very poor soils formed from loose sands: dolomite liming, use of a multi−component fertilizer with delayed action (Silvamix W) and temporary introduction of an admixture Alnus incana into the Pinus sylvestris plantation. The results of the factorial experiment after 9 years indicate that the soils on which the experiment was established cannot be afforested without prior rehabilitation treatments. The activity of dolomite was most effective while of Silvamix − weaker. Alder survived in the plantation composition only when used in combination with dolomite fertilization, then its rehabilitating effect was apparent. Rehabilitation relying on the use of dolomite at a rate of 2 t/ha in combination with a 50% admixture of alder in the pine plantation is recommended to be used in practice.

Opis:
On the basis of the wind damage risk model for forests using the data of the State Forests Information System, the stand damage risk factor Wr for each of the 430 forest districts in Poland and the threat measure Ms for a given forest district were determined. The measure of threat to forest Ms for a forest district is a methodical basis for assessing the potential damage to forests in Poland. Its value ranges from 8.1% for the Brzózka Forest District to 48.9% for the Ujsoły Forest District (fig. 1), giving the average value of 24.6% and standard deviation of 7.03%. The measure Ms was the basis for differentiating the levels of threat of wind damage to forest for forest districts. Level 1 (Ms≤10%) indicates low threat, level 2 (10%40%) – very high threat. Low threat to forests was found only in two forest districts located in the western part of the country. 113 forest districts, which form large concentrations particularly in western and central Poland, are exposed to an elevated threat. Most forest districts (233) are classified to a group of moderate threat. They are located across the country and are mostly concentrated in the northern and southern regions of Poland. 71 forest districts exposed to high threat are concentrated in the south of Poland in the Carpathians and the Sudetes, with scattered presence in the north of the country. Most of the 11 forest districts with a very high threat to forests are located in the mountains (tab., fig. 1). For the forest districts with a particularly high and very high threat, new silvicultural procedures and the basis for decision making in the field of forest management should be developed to reduce the risk of damage to forest.

Opis:
The aim of the study was to determine the relationship between the quality of habitat and the quality of Scots pine wood. We focused on the wood from mature stands growing on poor habitats on inland dunes in the Notecka Forest and on former farmlands (central and western Poland). We selected 12 trees, from which we took wood samples for tree ring investigation. We determined the age of trees, width of increments, share of late− and hardwood, and the moisture and density of the wood. Samples were weighed with 0.001 g accuracy and their volume was determined with hydrostatic method. Next, samples were dried and their mass was determined again. The obtained results were used to calculate: initial and conventional wood density as well as moisture content of each sample. Properties of the examined wood derived both from Notecka Forest as well as from farmlands were advantageous from the point of view of its technical quality. Mean width of annual increments, both near−pith and near−circumferential, ranged from 1.70 to 1.99 mm and qualified analysed wood as the narrow−ringed. The examined wood characterised high proportion of latewood, close to the upper limit given in literature for standard conifer wood and by high density. Mean share of latewood in the near−pith increments ranged from 18.9 to 30.6%, while in near−circumferential increments – from 34.3 to 45.7%. The highest average conventional density amounted to 507 kg/m³, whereas the lowest – to 466 kg/m³. The obtained results revealed that the wood from the Notecka Forest had favorable properties in terms of technical quality. It had the characteristics of slow−grown wood and was characterized by a high proportion of latewood in annual increments and a conventional density higher than the one reported in the literature.
