Pozycja Open Access Aktualny stan flory i znaczenie osobliwości florystycznych dla różnorodności szaty roślinnej rezerwatu „Grądowe zbocza” koło Recza(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Bacieczko, Wanda; Wołejko, Lesław; Katedra Dendrologii i Kształtowania Terenów Zieleni, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Katedra Dendrologii i Kształtowania Terenów Zieleni, Zachodniopomorski Uniwersytet Technologiczny w SzczeciniePresent state and the evaluation of vascular flora of the nature reserve „Grądowe Zbocza” is presented. In this forest-type reserve, situated in the Recz commune (Western Pomerania) 216 species of vascular plants were found, including 34 protected, endangered and rare species. Newly found localities of interesting species include two neophytes: Scutellaria altissima and Phyteuma nigrum, which are extremely rare in northern Poland. The occurrence of the majority of ineresting species is associated with the forest communities Circaeo-Alnetum and different forms of Stellario-Carpinetum, which are also listed as valuable and protected Natura 2000 habitats.Pozycja Open Access Chronione, zagrożone i rzadko spotykane gatunki roślin naczyniowych w gminie Boleszkowice (województwo zachodniopomorskie)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Ziarnek, Magdalena; Ziarnek, Krzysztof; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieAs a result of floristic research carried out in years 2001 and 2009 in Boleszkowice commune, 657 species of vascular plants were found. Among them 23 species are legally protected and 31 species of plants are listed in regional red book. Lots of species are rare in local or regional scale.Pozycja Open Access Flora użytków ekologicznych Szczecina(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Friedrich, Stefan; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieIn six sites of ecological interests in Szczecin there are in total 596 vascular plant species. Dominant in life forms are hemicryptophytes and the lowest participation have chamaephytes. Native species compose the three quarters of flora and among alien species predominate permanently settled ones. Participation of geographic-historical groups decrease in following order: apophytes, spontaneophytes, archeophytes, kenophytes, diaphytes and cultivated plants. Recognised species represent 15 social-ecological groups among which predominate meadow communities. Significant participation have also species of thermophilous oak forests and mesophytic deciduous woods and ruderal communities. The sites of ecological interest are the refuges for 55 protected and endangered species in Western Pomerania and whole Poland. The biggest mutual similarity show the floras of the sites of ecological interest: „Dolina strumienia Grzęziniec”, „Dolina strumieni Skolwinki, Stołczynki i Żółwinki” and „Dolina strumienia Żabiniec”, and the smallest one – „Klucki Ostrów”. The site of ecological interest of the most natural condition is „Klucki Ostrów” and the most changed site of ecological interest under anthropopressure is „Dolina strumienia Żabiniec”. The most valuable object regarding the flora richness and participation of protected and endangered species is SEI „Dolina strumienia Grzęziniec”.Pozycja Open Access Nowe stanowisko ostnicy piaskowej Stipa borysthenica i uwagi o jej rozmieszczeniu na Pomorzu Zachodnim(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Waloch, Piotr; Piotrowska, Julia; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieStipa borysthenica is a protected, vulnerable species which appears in a sandy dry grasslands. In Poland it is known from a few stands in the margin zone of the Lower Odra Valley. In 2006 a locality of this species was found in the vinicity of Dolna Odra power station near Gryfino (Western Pomerania, Poland). Stipa borysthenica occurs here in the Spergulo vernalis-Corynephoretum community. The increasing of tufts number from 29 in 2006 to 41 in 2010 indicates good condition of Stipa population. Devastation by people is the biggest threat to population of Stipa borysthenica.Pozycja Open Access Osobliwe oczko wodne na Pojezierzu Południowo-Ełckim(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Jasnowska, Janina; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe small pond (1.3 ha) in the moraine landscape of Pojezierze Ełckie is characteristic for its natural values, especially floral diversity, indicating the existence of various habitats in the same area. They are: the calciphilous charas community Charetum fragilis, representing EU Habitat Directive oligotrophic and mezotrophic water containers with underwater Chara meadows (code 3140), eutrophic waterlilies Nupharo-Nymphaeetum community and water milfoil community Myriophylletum spicati – representing old river-bed and natural eutrophic water containers with associations from Nymphaeion and Potamion (code 3150). Worth mentioning is also mezotrophic the north water lily community Nymphaeetum candidae, which is under strict protection. In the neighbourhood there are patches of riverside carr Circaeo-Alnetum (code 91EO) and Ficaro-Ulmetum (code 91FO) forests. There are also found other protected animal species. The map of objects’ vegetation with marked sites is presented. The analysis of phytocenoses’ distribution shows, that fertile habitats are connected to eutrophication caused by water flowing down from the crop fields, threatening nature mezotrophic habitats.Pozycja Open Access Potamogeton nodosus Poir.

I zbiorowiska pleustofitów w wodach przybrzeżnych Odry Zachodniej pod Szczecinem(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Kowalski, Wojciech W. A.; Wróbel, Mariola; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieAs a research result, which was carried out in inshore waters of the Odra Zachodnia river in Międzyodrze near Szczecin in years 2009–2010, was discovery of a new site of Potamogeton nodosus Poir. (= P. fluitans Roth p.p.) in Western Pomerania and Poland. Patches of Ranunculetum fluitantis Allorge 1922 association with Potamogeton nodosus as a characteristic species, co-occurrenced with rare associations of pleustophytes like Lemnetum gibbae Miy. et J.Tx. 1960 and Lemno minoris-Salvinietum natantis (Slavnić 1956) Korneck 1959. Lemnetum gibbae Miy. et J.Tx. 1960 association was first time observed in the area of investigations while protected water fern Salvinia natans and Lemno minoris-Salvinietum natantis (Slavnić 1956) Korneck 1959 association significantly spread in the last few years. Presented at research site plant associations of pleustophytes from Lemnetea class, identify protected nature habitat Natura 2000 Old river-beds and natural, eutrophic water bodies with associations from Nymphaeion and Potamion (code 3150).Pozycja Open Access Roślinność torfowisk alkalicznych rezerwatu „Wielkopolska Dolina Rurzycy”(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Wołejko, Lesław; Piotrowska, Julia; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieA survey of plant communities of 8 rich fens found in the newly established nature reserve „Wielkopolska Dolina Rurzycy” has been performed on the basis of the phytosociological research. A present day vegetation cover of these fens is composed of 11 plant communities belonging to three vegatation classes: Scheuchzerio-Caricetea nigrae, Phragmitetea and Molinio-Arrhenatheretea. The spatial relationship between the different mire components is analysed in respect to history of land use and the mire regeneration processes. Concepts of active mire protection is discussed in relation to particular local situation and hydrological conditions.Pozycja Open Access Stan i zagrożenia populacji Luronium natans (l.) Rafin w Jeziorze Orzechowskim koło Nowogardu(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Kowalski, Wojciech W. A.; Piotrowska, Julia; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieLuronium natans is a rare, endangered and protected species, which requires areas Nature 2000 to be designated. The research on the population of this species in Orzechowskie Lake (Western Pomerania, Poland) was conducted in 2007. 21 concentrations of Luronium natans, each on area 0.04–1.0 m2 were recorded and characterized. In 12 of them blooming specimens were observed, but fruits were not found. The plant propagates only vegetative on described site. On the basis of 12 releves Luronietum natantis community was distinguished with Luronium natans and Hydrocotyle vulgaris as dominant.Pozycja Open Access Szata roślinna i ochrona walorów rezerwatu „Kamienna Buczyna” na Pojezierzu Ińskim (województwo zachodniopomorskie)(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Ziarnek, Magdalena; Ziarnek, Krzysztof; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieThe paper presents results of floristic and phytosociological works provided in 2006 in nature reserve “Kamienna Buczyna” in Iński Landscape Park (NW Poland). The objective of reserve established in 1985 is preservation of forest communities and characteristic moraine landscape. There have been found 11 species under legal protection and 3 habitats protected in Natura 2000 area (Galio sylvatici-Carpinetum, Galio odorati-Fagetum i Luzulo pilosae Fagetum). There was observed regeneration of preserved forest habitats, but also degeneration of the parts of reserve where the coniferous treestand still exist.Pozycja Open Access Występowanie kokoryczy drobnej Corydalis pumila na Pomorzu Zachodnim(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2011) Ziarnek, Krzysztof; Ziarnek, Magdalena; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w Szczecinie; Zakład Botaniki i Ochrony Przyrody, Zachodniopomorski Uniwersytet Technologiczny w SzczecinieCorydalis pumila is a species rarely observed in Poland, only in north-west part of the land. It was known only from 11 localities in 2001 and in the Polish Red Data Book of Plants the species was recognized as vulnerable in the country. The paper presents 20 new localities of Corydalis pumila in Western Pomerania. The species has very rich populations in the Parsęta river basin. It was observed also on new locality on the Krąpiel river. Survival of the species is dependent on preservation of natural or semi-natural oak-hornbeam forests on the slopes of the valleys. Prospects of such habitat in Western Pomerania may be pretty good thanks to Natura 2000 network.
