Opis:
Sustainable development and afforestation measures aiming to preserve the leading role of the forests are important elements of spatial, environmental and economic policies. The economic efficiency of afforestation schemes covering arable and other types of land was evaluated in view of the policies aiming to increase the afforestation rate and improve the land−use structure in the rural areas. The evaluated afforestation measures were introduced in Poland in 2004 as part of the Rural Development Programme (RDP). The principles and criteria applicable to every RDP framework, i.e. 2004−2006, 2007−2013 and 2014−2020, were taken into account. Special attention was paid to processes that significantly influenced afforestation practices in the analysed periods. Economic efficiency was evaluated for two exemplary plots of arable land. The results of the profitability analysis indicate that current legislation discourages farmers from embarking on afforestation projects. The above can be attributed to the maximum permitted area of afforestation per beneficiary (no limitations in the previous RDPs, 20 ha in the present one), shorter validity of afforestation premiums (12 instead of 20 years) and the introduction of more rigorous afforestation criteria in 2015. The afforestation principles under RDP 2004−2006 were the most favourable for farmers, and the highest afforestation rates were reported during that period. Individual farmers could play an important role in the afforestation process. However, farmers' attachment to arable land, the availability of more profitable measures under the RDP, direct subsidies and the overestimation of the prices of arable land relative to forests discouraged afforestation, even in areas characterized by poor soils. On 1 May 2016, the Polish government introduced additional restrictions on trade in agricultural land, which would additionally decrease the popularity of afforestation measures among individual farmers.

Opis:
Investigations were carried out in 2000−2001 on the succession of carabid assemblages accompanying the spontaneous succession of pine stands on former agricultural land. Observations concerning changes in the number of carabid individuals and species, proportion of individuals in the groups: developmental, ecological, trophic, geographical, moisture preference, wing differences, as well as the mean individual biomass (MIB) indicated that the development of carabid assemblages during the spontaneous succession of stands can be compared to the regeneration process of the carabid fauna that accompany afforestation and that the direction of this development is similar to the development of carabid assemblages that accompany afforestation of farmlands.

Opis:
The presented study concerns the effect of the methods of soil preparation on the changes in the number and species composition of beetle assemblages occurring on the former farmland designed for afforestation. 48 research areas representing four soil preparation variants were established with Barber traps set up. 5,158 beetles representing 137 species from 27 families were collected during the study period. The results indicate that soil preparation on the former farmland consisting in deep ploughing and shallow ploughing with subsoiling favours the encroachment of both the ubiquitous and forest species leading to the faster development of forest type beetle assemblages. The preparation of soil on the former farmland by shallow ploughing and ridge formation favours the long−term presence of beetle assemblages in open areas.

Opis:
Presented studies were conducted in the territory of the Strzyżów Forest District, in English oak plantations established under the Programme for the Development of Rural Areas, 2004−2006. The aim of this study was to compare the density, height, and quality of oaks planted in autumn or spring and protected from deer damage with wire mesh fencing or chemical repellents. Obtained results allow to suggest that wire mesh fencing is a better method of protecting plantations from animal damage and has a significant impact on the density, height and quality of oaks. Positive effect of autumn planting on oak performance was noted only after the elimination of deer impact.

planting methods
Opis:
The aim of the study was to compare the growth of plantations established with manual and mechanical methods using planting material of various age. The experiment was established in 2000, in the Góra Śląska Forest District (W Poland) on a former farmland. One− and two−years−old Scots pine seedlings were used. Applied planting methods included: conventional planting bar, German Huff's dibble, trowel, Junack spade and three types of planting machines. The complete random block design with five replications was adopted. For the requirements of machine operation, unit plots were elongated rectangles with the longer side of 100 m and the shorter side of 4.5 m. Each plot consisted of three trenches. Spacing between seedlings in the trench was selected to ensure 10,000 seedlings/ha density. Measurements were carried out in 2000, 2001, 2002, 2003, 2008 and 2015. In the first five dates all heights were measured and seedling survival rates were established based on the number of measurements. In 2008 and 2015 all diameters at breast height were measured. In 2015 height of sample trees was recorded, while the height of the other trees was calculated according to the Prodan model h=d2/(a+bd+cd2)+1.3. Based on the measured diameters at breast height and established heights, basal area at the breast height and total tree volume were calculated for each plot. Survival rate is the primary parameter in the evaluation of planting methods, as it most effectively differentiates treatments. Stand height showed no significant diversification with regard to the treatments. For mean diameters at breast height the only differences were found between two−year old and one−year old seedlings, irrespective of the planting method. Despite the lack of differences in growth, effects of various planting methods and different planting material remain and as a result of high class timber already found in the stand these effects have become economically important. The decision on the selection of a particular planting material type and planting method has extensive economic consequences, as it affects productivity of grown stands at least at the first thinning operations. Planting machines are good tools in the establishment of forest cultures and the quality of their work exceeds that of manual operations.

Opis:
Between 2009 and 2011, behaviour of 15 field roe deer living in agricultural landscape in western Poland was studied using the radio telemetry method. Observed animals were active during the entire day with two distinct peaks – at the dawn and at the dusk. Moreover, night activity was greater than the day one. Such activity pattern may result from frequent human presence in the field roe deer habitat. Throughout the year, the activity rate (locations of active roe deer/all locations ratio) was higher in the agricultural lands than in clumps and belts of trees, which the most likely was the consequence of availability of easily digestible food in the crop fields (during growing season as well as after its end). Furthermore, field roe deer activity in open farmlands was the subject to bigger changes – both during warm months and in the winter it was the highest during the lowest temperature. Such changes were not observed in mid−field places with trees. However, in such places the activity rate was higher during periods of snow cover than during snowless ones.

Opis:
Analyses were conducted on wood from twelve Scots pines from northern Poland, aged 102 to 110 years, growing on former farmland and on forest grounds. The study was an attempt to determine basic density of wood, compressive strength along the grain, bending strength of absolutely dry wood and wood with moisture content above saturation point. Desorption strengthening was determined for analyzed strength properties of wood. Wood properties were determined in terms of juvenile and mature wood zones. Generally pines growing on former farmlands were characterized by wood with higher density and slightly lower strength than pines growing on typical forest soils. Conducted investigations indicate varied structure and properties of wood tissue formed in pines growing on former farmlands, which is different from that of typical forest soils.
