“…Smalltussock species with low competitive ability enable a high survival of Iris sibirica seedlings, whereas tall perennial plants eliminate seedlings by shading them and by mechanical effect of the vegetable mass. It should be mentioned also that survival of seedlings of Iris sibirica was markedly higher than the survival rate of Iris pseudacorus and Filipendula ulmaria seedlings developing in artificially created gaps and in natural conditions (Faliñska 1986(Faliñska , 1995. Performed observations confirm that species of low and high competitive ability did not accelerate the death of clusters of Iris sibirica ramets.…”

“…At later age stages, the effectiveness of vegetative reproduction gradually declines. In natural conditions, the unabated growth of individuals is occupied by neighbouring plants (Faliñska 1986(Faliñska , 1995(Faliñska , 1997.

Two populations of Iris sibirica, a clonal species protected by law in Poland, occurring in patches of Molinietum caeruleae, of similar floristic composition although with different dominant species, were studied. In the Stanis³awice locality, species with a high competitive potential prevailed, contrary to the Opatkowice locality, where the species of low competitive potential dominated. It was established that vegetative propagation ensures the continued presence of populations in both localities, although the proximity of plants with high competitive potential limits the vegetative propagation of ramet clusters of Iris sibirica. Despite the high level of seed production, the recruitment of seedlings in both patches is possible only in artificially created gaps. The field observations support the conclusion that creating gaps allowing for germination of seeds and development of seedlings, as well as eliminating expansive neighbours allowing proliferation of ramet clusters of Iris sibirica, is an affective way of protecting populations of this species.

The Sandhill Wetland (SW) and Nikanotee Fen (NF) are two wetland research projects designed to test the viability of peatland reclamation in the Alberta oil sands post‐mining landscape. To identify effective approaches for establishing peat‐forming vegetation in reclaimed wetlands, we evaluated how plant introduction approaches and water level gradients influence species distribution, plant community development, and the establishment of bryophyte and peatland species richness and cover. Plant introduction approaches included seeding with a Carex aquatilis‐dominated seed mix, planting C. aquatilis and Juncus balticus seedlings, and spreading a harvested moss layer transfer. Establishment was assessed 6 years after the introduction at SW and 5 years after the introduction at NF. In total, 51 species were introduced to the reclaimed wetlands, and 122 species were observed after 5 and 6 years. The most abundant species in both reclaimed wetlands was C. aquatilis, which produced dense canopies and occupied the largest water level range of observed plants. Introducing C. aquatilis also helped to exclude marsh plants such as Typha latifolia that has little to no peat accumulation potential. Juncus balticus persisted where the water table was lower and encouraged the formation of a diverse peatland community and facilitated bryophyte establishment. Various bryophytes colonized suitable areas, but the moss layer transfer increased the cover of desirable peat‐forming mosses. Communities with the highest bryophyte and peatland species richness and cover (averaging 9 and 14 species, and 50%–160% cover respectively) occurred where the summer water level was between −10 and −40 cm. Outside this water level range, a marsh community of Typha latifolia dominated in standing water and a wet meadow upland community of Calamagrostis canadensis and woody species established where the water table was deeper. Overall, the two wetland reclamation projects demonstrated that establishing peat‐forming vascular plants and bryophytes is possible, and community formation is dependent upon water level and plant introduction approaches. Future projects should aim to create microtopography with water tables within 40 cm of the surface and introduce vascular plants such as J. balticus that facilitate bryophyte establishment and support the development of a diverse peatland plant community.

ZusammenfassungBis weit in unser Jahrhundert bestanden grok Teile des Griinlandes des nordwestdeutschen Tieflandes aus extensiv bewirtschafteten artenreichen Feuchtwiesen. Eine Nutzungsaufgabe fuhrt in diesen Systemen zu Verschiebungen im Konkurrenzgefuge der Ptlanzenarten und lost Veriinderungen in der Vegetationszusammensetzung und -struktur aus. Die Sukzession nach der Nutzungsaufgabe ist durch die Abfolge charakteristischer Brachestadien gekennzeichnet: Nach einer Initialphase (Brachestadium I) kommt es zur Ausbildung artenarmer Dominanzbestiinde hochwiichsiger Pflanzenarten, die bereits im Ausgangsbestand vorhanden waren (Brachestadium 11). Der weitere Sukzessionsverlauf wird durch das Einwandern und die Etablierung von krautigen Arten ausgelost, die in den Besthden zur Kodominanz gelangen (Brachestadium 111). SchlieSIich kommt es zur Einwanderung und Etablierung von GehBlzen, so daB sich GehBlzbestZnde ausbilden (Brachestadium IV). Im Laufe der untersuchten Sukzession (Brachestadium I bis 111) geht die Artenzahl ebenso zuriick wie die Diversitiit und die Evenness. Es kommt zur Ausbildung hochproduktiver Bestande sowie zur Ausbildung einer machtigen Streuschicht (bis zu 500 g/m2), so daB die Keimung und Etablierung vieler Arten behindert werden.Die in der Sukzession aufmtenden Arten konnen nach ihrem dynamischen Verhalten vier Sukzessionskategorien zugeordnet werden: Die Dekkungsanteile der Arten der Sukzessionskategorie A und B gehen im Laufe der Sukzession zuriick. Wthrend Arten der Sukzessionskategorie A (z. B. Lychnis jlos-cuculi. Anrhoxanrhurn odoratum) in spiiteren Sukzessionsstadien lokal aussterben, kommen Arten der Sukzessionskategorie B (z. B. Cirsium olera- SummaryUntil the late fifties of this century, species rich wet meadows were characteristic for the swampy alluvial plains in Schleswig-Holstein (North-western Germany). Today, many of these meadows undergo successional changes due to abandonment. The vegetation development after abandonment can be characterised as a sequence of different successional stages. After an initial phase (successional stage I) follows a phase of clonal expansion of highly competitive species (successional stage 11) of the initial meadow community and a phase of immigration and establishment (successional stages Ill and IV) of species from the surrounding area. During the investigated successional sere (successional stages I to In) species richness, diversity and evenness is decreasing. Highly productive vegetation-stands are develop ing and litter packages up to 500 g/m' are limiting germination and establishment of many plant species.The succession can be characterised as a plantby-plant replacement. The species occumng in the successional sere can be classified into four successional categories according to their reaction to abandonment. The abundance of species of the successional category A (e.g. Lychnis flos-cuculi, Anrhoxanthum odoraturn) decreases after abandonment; these species have become locally extinct during the investigated succession. While species of ...
