    Opis:
    Young forest plantation established on abandoned agricultural land were compared to spontaneously developing young forest in order to evaluate their impact on biological activity of the soil. The study area was planted by pine trees in number 7 thous. per hectare. Aditionally, phytoameliorative tree species were planted singly on these plots in the following number: 1,5 thous., 3 thous. and 5 thous. per hectare. Some plots were pine monoculture.The following variant of site preparation prior to afforestation were used: agricultural ploughing (deep to 25 cm), agricultural ploughing with countersinking, deep ploughing (to 40−50 cm) and countersinking with ridges. All applied site preparation technics have detrimental effect on soil mesofauna. Collembola communities of five−year pine plantations are impoverished form of open area fauna. Phytoameliorative tree species do not accelerate soil fauna developement during the first years of secondary forest succession. Developement of soil fauna on abandoned agricultural land has been noticeably promoted by spontaneous succession of forest ecosystem.

    Opis:
    Based on experiment established in pine forest of Spychowo Forest District, it was proved that clearcut caused negative changes in forest springtail communities. The logging of a whole stand reduced the number of species and their abundance. The decrease in springtail abundance depended on the method of site preparation prior to afforestation. The highest reduction was recorded in logged areas where stripes had been plowed using forest reversible plough. Regressive changes in communities were also observed on harvested sites prepared by an active plough and rotary cultivator. The attempts of clearcut improvement by addition of wood chips or leaving debris piles on logged areas were evaluated on the base of the response of springtail communities. In both cases, the number of species and abundance were higher comparing to clearcut areas without logging residuals. Also residual patches of old growth left on harvested sites had positive effect on Collembola communities. Species richness and abundance observed in those paches were higher than in control mature stands.

    Opis:
    The resilience of forest ecosystems to climate changes such as elevated temperature and frequent drought episodes, strongly depends on how the soil subsystems and its inhabitants responds to these perturbation. The epigeic soil Collembola communities of mature mixed deciduous forest and adjacent young plantation on moderately humid soil were compared in two consecutive years, out of which the second one was marked by significant deficiency of precipitation in growing− −season. The study plots were established on the area of experimental forests of Warsaw University of Life Science−SGGW in Rogów (central Poland). The objectives of the study was to assess the sensitivity of forest Collembola communities to drought stress and to check if the reaction depends on stand age. We also aimed to test if an indicator species of climate changes can be appointed. The results showed that three months drought episode had negative impact on forest Collembola communities of mature stands, while communities of young plantation were not affected. The reduction of total abundance of Collembola and clear changes in communities structure in mature stand was detected in the year of lower precipitation. The Collembola communities of young plantation were also significantly transformed, but in result of clear cutting and soil preparation. Therefore, the successional changes were the most evident process in these communities and there were no signs of drought influence. Among the most numerous species in Collembola communities of mature forest Isotomiella minor was appointed as an indicator of drought, because its abundance was drastically reduced in the year of lower precipitation. The small number of specimen of this species in young plantation may also prove its sensitivity to deficiency of humidity in soil. The significantly negative response to drought episode was documented also for Psuedosinella horaki, Micraphorura absoloni and Megalothorax minimus. Our study provided strong evidence that the drought, which lasted only three months, had a detrimental effect on forest Collembola commu− nities.

    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.
