    The paper presents the results of research on the directions of succession and the current state of vegetation of the island Chełminek, formed 100 years ago from sandy sediments deposited as a result of the deepening of the fairway Szczecin-Świnoujscie. This anthropogenic ecosystem is distinguished by well-developed forest and scrub vegetation. The most valuable natural habitats, and also the best developed are patches of riparian vegetation, especially alluvial poplar and ash forests - the priority habitats protected in the European Union. Anthropogenic origin of the island contributed to the development of synanthropic flora and few taxa under legal protection. Planned in future resumption of sandy sediment storage requires a diagnosis of the current state of vegetation of this anthropogenic island, an indication the most valuable natural habitats as well as emphasises the changes which have occurred in the last 30 years in this area, since discontinued its use.

    Factors affecting development of pioneering psammophilous Dune vegetation on Przytorska Sandbar (Nature 2000 site „Wolin and Uznam” PLH320019)

    The influence of selected environmental factors on shaping sandy beach habitats as a place for the growth of psammophilous and halophilous plants were the purpose of a research performed in the years 2013–2014 on Przytorska Sandbar (Natura 2000 area „Wolin and Uznam” PLH320019). The research was performed on a beach section, which was excluded from recreational use, and closely bordered with the external port basin of the Liquid Natural Gas terminal under construction, where also the abrasive influence of storm surges had been diminished. Research results indicated a dominant influence of aeolian sand material accumulation in shaping embryo dunes inhabited by pioneer species of psammophilous and halophilous plants - Elymus farctus subsp. boreoatlanticus and Honckenya peploides – species characteristic of the plant association of Honckenyo-Agropyretum juncei R.Tx. 1955, identifying the natural habitat of the initial stages of coastal white dunes (habitat code: 2110), the parts of which had been observed in the research area as a classically shaped form. The presence of Ammophila arenaria and Leymus arenarius creating initial forms of grassy vegetation association of Elymo-Ammophiletum indicated a proceeding stabilisation of embryo dunes – evolving into a foredune. A strong sea accumulation of sand material and simultaneous decrease of abrasive storm-tide influence enabled the development of an ecologically and geographically foreign species Salix daphnoides, diasporas of which were located in the area of lower beach.

    Potamogeton nodosus Poir. (= P. fluitans Roth p.p.) 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 Szczecinie
    As 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).

    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 Szczecinie
    Luronium 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.

    The New Locality of Ranunculetum Fluitantis Allorge 1922 Plant Community and Species of Rhodophytes in the Myśliborka Stream (The Natura 2000 Site „Ostoja Wkrzańska” Plb 320014)
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Kowalski, Wojciech W. A.; Wróbel, Mariola; Banaś-Stankiewicz, Urszula; Komarzewska, Katarzyna; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin, Poland; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin, Poland; Department of Botany and Nature Protection, West Pomeranian University of Technology, Szczecin, Poland; Provincial Inspectorate for Environmental Protection in Szczecin, Szczecin, Poland
    Described the border site of Ranunculetum fluitantis Allorge 1922 plant association in the Myśliborka stream documents the new location of "Lowland and foothill rivers with batrachion vegetation communities Ranunculion fluitantis (code – 3260)" in Western Pomerania and in the Natura 2000 site "Ostoja Wkrzańska" PLB 320014. In waters of the stream verified the presence of rare species of hydrophytes positions such as shiny pondweed Potamogeton rutilus and freshwater rhodophytes: Batrachospermum atrum and B. gelatinosum. The occurrence of these taxa in waters of the stream indicates the oligo-and mesotrophic nature of the habitat which confirmed results of hydrochemical analysis of waters.
