    Właściwości chemiczne gliniastych gleb uprawnych o zróżnicowanej rzeźbie terenu z uwzględnieniem zbiorowisk roślinnych po piętnastu latach odłogowania. Cz. II. Zbiorowiska roślinne w obrębie wierzchowiny, zbocza i w obniżeniu

    After a period of 15 years, 17 phytosociological relevés were taken in 2006, on a slope top, on a slope and in a ground lowering area within the soils formed from loam. In 1993 (the first year of fallowing), segetal communities were observed on the slope, on the slope top and in the ground lowering. The slope and the slope top were settled by phytocoenoses of the Aphano-Matricarietum consolidetosum subassociation with a considerable contribution to them of the species of the Sisymbrietalia order. Whereas in the ground lowering, a typical subassociation Aphano-Matricarietum occurred. After 15 years no species characteristic of the subassociation and the association present in 1993 were recorded. In the process of the secondary succession a gramineous community Convolvulo arvensis-Agropyretum repentis appeared. In a part of this syntaxon, mainly on the slope top, a variant with Arrhenatherum elatius, and on the slope a variant with an aggressive species Calamagrostis epigejos were distinguished. In the ground lowering, dominating are the species characteristic of the Ranunculo-Alopecuretum geniculati association: Ranunculus repens, Agrostis stolonifera and Agrostis geniculatus of the Molinio-Arrhenatheretea class. In both communities the species of scrub communities Rosa canina, Crataegus monogyna and forest communities Fraxinus excelsior also occur, however, less frequently. The seeds of the latter species spread anemochorically on the studied area from the adjacent roadside plants. The presence of these species indicates the taking place process of an ecological succession leading towards the formation of scrub communities.

    The fifteen year period of the fallowing of a loamy soil of a differentiated land relief caused an increase, as compared with the results of the studies carried out in 1994, in the soil acidity in all the studied elements of the relief. After such a long period of fallowing, no distinct changes were observed in humus resources, in the C : N ratio and in the content of available phosphorus. Whereas the resources of available potassium and magnesium increased in the soil layer up to a depth of 60 cm.

    Zbiorowiska muraw kserotermicznych i piaskowych na krawędzi doliny Odry w Owczarach
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2012) Kutyna, Ignacy; Drewniak, Ewa; Młynkowiak, Elżbieta; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Klub Przyrodników w Świebodzinie, Stacja Terenowa Owczary 17, 69-113 Górzyca; Katedra Ochrony i Kształtowania Środowiska, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie
    Ecological and phytosociological studies concerning plant communities carried out in: Protected Area "Owczary", Ecological Arable Lands "Owczary I and II" and "Laski I and II" as well as within Nature Reserve "Pamięcin" situated in Owczary or in its neighbourhood. 49 phytosociological relevés were taken on xerothermic and psammophilous grasslands. Four communities in the rank of associations were distinguished. Phytocenoses of the Potentillo- -Stipetum capillatae association - stipa grassland, are found on S and SW slopes, mainly on soils formed from light loam of alkaline reaction, containing calcium carbonate. Similar soils are settled by phytocenoses of Adonido-Brachypodietum pinnati, occurring on slopes and slope tops of hills. They are a dominant community in the studied area. In the patches of association there are practically no characteristic species of the Potentillo-Stipetum capillatae association. The species of the Festucetalia valesiacae order and taxa characteristic of the Sileno otitis- -Festucetum association are also less frequent. Within grasslands lying on sand two communities were recognised, Sileno otitis-Festucetum and Diantho-Armerietum elongatae. Phytocenoses of both associations are mainly settled on sandy soils of alkaline reaction (Sileno otitis-Festucetum) and acid and slightly acid reaction (Diantho-Armerietum elongatae). Among 124 recorded species in plant communities there are taxa under strict species protection: Anthericum liliago, Campanula sibirica, C. bononiensis, Orobanche lutea, Oxytropis pilosa, Scorzonera purpurea, Stipa joannis and S. capillata. They are also settled by species which are under partial species protection: Helichrysum arenarium, Primula veris and Ononis spinosa. Except for protected species in communities, there are a series of rare species that are in danger of extinction: Asperula tinctoria, Carex humilis, Eryngium campestre, Hieracium echioides, Prunella grandiflora and Thesium linophyllum.
