Opis:
The aim of the study was to determine the rate of mineralization of needles in a pine stand in relation to site and to microbiological conditions occurring on dune slopes of contrasting aspects. The research was conducted in the old−growth pine forest overgrowing a latitudinally located dune in the Bydgoska Forest (N Poland). On contrasting dune slopes (northern and southern) rate of mineralization of pine needles was investigated in the 2−years experiment (2012−2014) with the litterbag method. Besides, following investigations were conducted in the middle part of both slopes: 1. dynamics of soil moisture and soil temperature were measured at a depth of 3 cm for 18 days during the 2013 growing season (interval of 2 weeks was applied) and 2. populations of bacteria and fungi were determined for all subhorizons of organic soil horizon (Ol, Of, Oh) as well as for a mineral horizon (AEs) of both soils. Weight loss of needles was found to be higher on northern than on a southern slope what was consequently stated for all 4 terms of taking measurements (6, 12, 18 and 24 months after placement of litterbags). The discrepancy has increased with time and after 2 years it equaled 14.7% when the loss was 61.1% for northern and 46.4% for a southern slope. It could be surprising that such differences were found in spite a sunny slope was characterized by stated in a study higher soil temperature. It should have a stimulating effect on mineralization of organic material; however a soil located on a southern slope was also found as much drier. Thus, the periodic deficiency of soil moisture was indicated as a limiting factor for occurrence of both bacteria and fungi on a southern slope due to the numbers of both groups of microorganisms were much lower on the slope than on a northern aspect. Conditioned by more favourable site parameters, higher number of microbial population occurring on a shadow slope could explain higher rate of mineralization of needles stated for the slope aspect. The moisture factor can be of especially high significance for microbial occurrence and activity and thus for litter decomposition just in dry inland dune ecosystems. It was concluded that in relatively monotonous pine forests overgrowing dry and poor in nutrients soils of inland dunes the slope aspect is an agent significantly differentiating both site and soil microbial conditions.

Opis:
The research was conducted in a young Scots pine (Pinus sylvestris) plantation located in a dune area of the Toruń Basin (N Poland). The aim of the study was to investigate differences in dynamics of soil water conditions followed different method used for site preparation. The three plots were investigated in the study: belt of soil prepared by a mill, north−facing slope of a dune (FR−N), belt of soil prepared with a mill, south−facing slope of a dune (FR−S) and soil prepared with a plough (furrows) on the ridge of a small aeolian mound (LPZ). On each plot soil samples were taken and soil moisture was regularly measured from April to December of 2013 (the TDR method). The measurements of soil moisture were taken at four depths (3, 10, 25 and 50 cm) at intervals of ca. 2 weeks. Additionally, soil moisture was also measured on 25.08.2015. It was done to determine soil water conditions for a deep summer drought (the measurements were taken twice this day – just before and after rain which turned to be the first since ca. a month). Reserves of soil moisture and shares of water unavailable to plants were calculated for every measure day for each study plot. As a result of higher organic carbon content, values of soil actual moisture as well as reserves of soil moisture were almost regularly higher for belts mixed with a mill than for furrows prepared with a plough (fig. 1, 3). Opposite relation was found, however for the summer drought (tab. 2). This was explained by the higher repellence of rich in organic mater, dried material occurring in belts. On 25.08.2015 much lower improvement of water conditions after rain was also stated for this material than for topsoil in LPZ. Unfavoured soil water conditions for plants occurring in belts in dry periods could explain relatively low dynamics of pine growth revealed for the variant of soil preparation in a previous study. However, it was concluded that a forest mill should be recommended for forestry, because the device much less disturbs topsoil than a plough. Besides, differences in growth parameters of pines followed different methods of soil preparation used before planting decline in next years of a stand growth.

Opis:
The objective of the study was to determine the dynamics of soil temperature on inland dunes in the Toruń Basin (N Poland) with reference to the two methods of site preparation: homogenization of belts with a forest mill (FR) and preparation of trenches with a double−mouldboard plough LPZ−75 (LPZ). The study was conducted in a young Scots pine (Pinus sylvestris) plantation on plots with soil prepared by a forest mill on north− and south−facing slopes of a dune (FR−N and FR−S respectively) and with soil prepared with a plough on the ridge of a small aeolian mound (LPZ). On each plot a soil pit was dug and soil samples were taken from distinguished horizons for laboratory analyses. Besides, from April to December of 2013, at interval of ca. two weeks, soil temperature was measured at the depths of 3, 10, 25 and 50 cm. To estimate daily amplitudes of temperature in topsoil on the studied plots, in a sunny summer day (23.08.2013) the temperature was additionally measured from 5 a.m. to 9 p.m. with an hourly interval. These measurements were taken at the two upper depths (3 and 10 cm). Despite the fact that soil surface was distinctly darker for belts prepared with a mill than in trenches prepared by a plough, soil temperatures were almost regularly lower in FR−N and in FR−S than in LPZ. This concerns all the investigated depths. The differences were explained by much higher moisture of soil material in belts what involves higher thermal capacity and with that slower heat of a soil, as well as causes higher losses of thermal energy for evaporation. Another agent explaining this was indicated to be related to high porosity of materials found in the belts. Namely, especially in dry periods, high volume of soil pores are filled on the FR plots with air what impedes heat transfer in a soil. It was concluded that stated in a previous study worse growth of pines planted in milled belts than in tranches prepared with a plough was unlikely related to differences in soil thermal conditions. Thus, differences in growth dynamics of young pines in plots with site prepared by the two studied methods are caused by other reasons rather as primarily other competitive impact of weeds and differences in soil water conditions occurring at root system of young trees.

Opis:
Na terenie Puszczy Kozienickiej stwierdzono 18 typów siedlisk przyrodniczych chronionych w ramach europejskiej sieci Natura 2000. W piętnastu rezerwatach przyrody (o powierzchni 1267 ha) siedliska te zajmują znaczne przestrzenie, a w niektórych z nich dominują powierzchniowo. W artykule zaprezentowano krótką charakterystykę i główne zagrożenia wszystkich zbadanych siedlisk, które zebrano w 6 grup ekologicznych. Są to: 1) wydmy śródlądowe z murawami napiaskowymi (kod 2330), 2) starorzecza, zbiorniki eutroficzne, nizinne rzeki ze zbiorowiskami włosieniczników oraz zalewane muliste brzegi rzek (3150, 3260, 3270), 3) niżowe murawy bliźniczkowe, łąki trzęślicowe, ziołorośla nadrzeczne i świeże łąki ekstensywnie użytkowane (6230, 6410, 6430, 6510), 4) torfowiska wysokie, przejściowe, trzęsawiska, przygiełkowiska (7110, 7120, 7140, 7150), 5) bory sosnowe: bagienne i chrobotkowe oraz wyżynny bór mieszany jodłowy (91DO, 91TO, 91P0), 6) grąd subkontynentalny, łęgi i dąbrowa ciepłolubna (9170, 91EO, 91IO). Z punktu widzenia biogeograficznej reprezentatywności siedlisk przyrodniczych Puszcza Kozienicka jest ważnym na mapie Polski obiektem. Dotyczy to przede wszystkim grądów (Tilio-Carpinetum), wyżynnego jodłowego boru mieszanego (Abietetum polonicum) oraz torfowisk (Sphagnetum magellanici, Rhynchosporetum albae i in.). Badania dostarczyły argumentów przemawiających za włączeniem w granice Obszaru Ochrony Siedlisk Puszcza Kozienicka kilku kompleksów dobrze zachowanych siedlisk łąkowych i in. nieleśnych o łącznej powierzchni 2200 ha. Korekta granic SOO zwiększyłaby wydatnie możliwości ochrony pełnej różnorodności siedlisk przyrodniczych Puszczy Kozienickiej.
In the Kozienicka Primeval Forest there were found 18 habitat types protected in the European Ecological Natura 2000 Network. In the 15 nature reserves (area 1267 ha) these habitats occupy large areas, and in some reserve they are dominant element of vegetation. The paper presents short characteristics and main threats of all studied habitats, which were joined in 6 ecological groups. They are: 1) inland dunes with open grasslands (2330), 2) natural eutrophic lakes, water courses of plain with the Callitricho-Batrachion vegetation and muddy river banks (3150, 3260, 3270), 3) lowland Nardus grasslands, Molinia meadows, hydrophilous tall herb fringe communities and lowland hay extensive meadows (6230, 6410, 6430, 6510), 4) raised bogs, transition mires and quaking bogs and depressions on peat substrates of the Rhynchosporion (7110, 7120, 7140, 7150), 5) pine bog woodland, lichen pine forests, Holy Cross fir forests (91DO, 91TO, 91P0), 6) sub-continental oak-hornbeam forests, alluvial forests and thermophile oak woods (9170, 91EO, 91IO). From the point of view of biogeographically representatives of natural habitats The Kozienicka Primeval Forest is an important object in Poland. First of all, it concerns: oak-hornbeam forest (Tilio-Carpinetum), Holy Cross fir forests (Abietetum polonicum) and bogs (Sphagnetum magellanici, Rhynchosporetum albae). This research provides arguments to include to the Habitats Conservation Area – Kozienicka Primeval Forest some well-preserved meadows and other non-forest habitats complexes with total area of ca. 2200 ha. Suggested correction would greatly contribute to conservation of complete diversity of natural habitats of the Kozienicka Primeval Forest.
