Opis:
Alternative methods of oak cultivation aim at reducing the cost of establishment of young plantations and decrease in the expenditure on their tending. In these methods, the corridors consisting of oak seedlings planted in the rows or isolated groups of twenty six seedlings are enclosed by stripes or patches without intervention left for natural succession. The restriction in site preparation on these areas and spontaneous development of young generation of trees are assumed to create favourable conditions for many forest organisms and, in results, significantly improve biological diversity of the managed forests. The aim of the study was to recognize the response of forest collembolan assemblages on alternative methods of establishment of oak plantations. The study was performed in the Forest Experimental Station in Rogów (Central Poland). In a mature stand on moderately humid mixed deciduous forest site, on clear−cut and on oak young plantations made by corridor and tree groups methods, fifteen study plots were established. In case of young plantations, these plots encompassed both artificially planted corridors or tree groups and adjacent fragments of plantation left for natural succession. Soil samples were taken in June and September 2014 and, using a simplified Tullgren apparatus, 18 thousands of collembolan specimens belonging to 84 taxa were identified. Our study proved that clear−cut and site preparation by rotary tiller on moderately humid mixed deciduous forest had a negative impact on Collembola assemblages, because caused a reduction in species number and abundance. However, the establishment of oak plantations by alternative methods, consisting in abandonment an artificial planting on some patches of renewed plots, significantly mitigate negative effects of clear−cut and reforestation on collembolan assemblages. The species number and abundance of springtails on patches left for spontaneous succession were distinctly higher than in artificially planted corridors or groups of trees in case of all studied plantations. Furthermore, it seems that corridor method in oak plantations establishment is advantageous for forest springtails, because the number of specimens per square meter on corridor plantation was higher than in tree group method. The beneficial effect on soil fauna of alternative methods of oak cultivation described in this paper weighs in favour of their wider application in silviculture.

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:
The experiment area was located in the territory of the Góra Śląska Forest District (western Poland). The plantation was established in 2000 on former agricultural land. One− and two−year−old Scots pine seedlings were used in the experiment. The planting methods applied included wedge planting with a traditional forest and Huff’s dibblers, a garden planting spade, a ‘Junack’ spade and three types of planting machines. Measurements were taken in 2000, 2001, 2002, 2003 and 2008. Differences in the growth characteristics of plantations and young stands are not only statistically significant, but also of great practical importance. The operation of planting machines was significantly more effective, which was manifested in a higher survival rate, height growth, and larger breast height diameters and total basal area. Huff’s dibbler fell short of expectations as a hand tool.

Opis:
The paper evaluates seedling performance in a forest culture five years after its establishment. Three pre−winter and one spring planting dates have been tested using root−balls and bare−roots seedlings. Both types of seedlings planted before winter showed the same quality, while the quality of seedlings with root−ball planted in spring was higher. Seedlings with root−ball were not affected by the time of planting. Differences between root−ball and bare root seedlings planted in spring increased throughout the entire five−year test period.
