Die Wälder von Magdeburgerforth (Fläming, Sachsen-Anhalt) – eine Wiederholungsuntersuchung nach sechs Jahrzehnten

Thea Dittmann, Thilo Heinken & Marcus Schmidt
Between 1948 and 1950 the German phytosociologist Harro Passarge conducted 120 relevés in a 2,200 ha large forest area near Magdeburgerforth (Fläming, Saxony-Anhalt, NE Germany). The study area is characterized by a remarkable diversity of forest communities of the alliances Agrostio-Quercion petraeae, Alnion glutinosae, Alnion incanae, Carpinion betuli, Dicrano-Pinion and Quer-cion roboris. Because of this broad ecological spectrum, and because many processes which impact Central European forests today (nitrogen deposition, climate change) were not noticeable...

An overview of aquatic vegetation in Serbia

Dušanka Lj. Cvijanović, Dmitar V. Lakušić, Milica M. Živković, Maja Z. Novković, Ana A. Anđelković, Danijela M. Pavlović, Dragana M. Vukov & Snežana B. Radulović
The majority of aquatic vegetation studies in the Middle Danube Basin (Serbia) were done inde-pendently during the last two decades, including data from small areas, which resulted in several classification solutions. The main purpose of this paper was to develop a numerical classification of the aquatic vegetation in Serbia, without fitting the vegetation groups into the existing phytocoenolog-ical classification scheme. Datasets of (i) surface and subsurface vegetation of free-floating duck-weeds, ferns, liverworts and bladderworts, and...

Dry grassland vegetation of Central Podolia (Ukraine) – a preliminary overview of its syntaxonomy, ecology and biodiversity

Anna A. Kuzemko, Thomas Becker, Yakiv P. Didukh, Ioana Violeta Ardelean, Ute Becker, Monica Beldean, Christian Dolnik, Michael Jeschke, Alireza Naqinezhad, Emin Uğurlu, Aslan Ünal, Kiril Vassilev, Evgeniy I. Vorona, Olena H. Yavorska & Jürgen Dengler
We present the data of the 2nd research expedition of the European Dry Grassland Group (EDGG), which was conducted in 2010 in Central Podolia, Ukraine. The aim was to collect plot data to compare Ukrainian dry grasslands with those of other parts of Europe in terms of syntaxonomy and biodiversity. We sampled 21 nested-plot series (0.0001–100 m²) and 184 normal plots (10 m²) covering the full variety of dry grassland types occurring in the study...

Formalised classification and environmental controls of riparian forest communities in the Sudetes (SW Poland)

Remigiusz Pielech
The Cocktail method was applied to a small data set derived in a regional survey on riparian forest in the Polish part of the Sudetes. Formalised classification revealed the occurrence of seven associations. Considering the ecological character, three distinct groups emerged among them: i) alluvial forests (Salicetum albae, Alnetum incanae), ii) forests of small and medium mountain streams with only a narrow riparian zone (Salicetum fragilis, Stellario nemorum-Alnetum glutinosae and Fraxino-Alnetum) and iii) forests developed...

Effects of water regime and agricultural land use on diversity and species composition of vascular plants of temporary ponds in northeastern Germany

Sara Altenfelder, Uwe Raabe & Harald Albrecht
Fluctuations of the water level at the edges of temporary water bodies provide favourable living conditions for annual plant communities of the phytosociological class Isoëto-Nanojuncetea. Such communities of periodically flooded ponds within the agricultural landscape of NE Germany are particularly rich in rare plant species of that class. During the past decades drainage, fertilisation and herbicides in the surrounding arable fields have led to a severe decline in diversity of these species. To develop efficient...

Retamoid scrubs of the Cytisetea scopario-striati in the Netherlands: a new approach to classify marginal associations

Rense Haveman, Iris de Ronde & Joop H.J. Schaminée
Marginal associations, i.e. floristically impoverished associations at the margin of the distribution area of a higher syntaxon, form a problem in vegetation classification, because true character species are lacking. We propose a new approach for the classification of such marginal associations, making use of the notion of 'chorological tension zones'. In the absence of true character species, the species from other syntaxa of the same formation can be used as such. Our proposal is to...

Restoration possibilities of dry grasslands afforested by pine: the role of seed bank and remnant vegetation

Anna Szabó & Eszter Ruprecht
Stipa-dominated steppe-like dry grasslands represent a great nature conservation priority in Ro-mania and in the whole European Union. In Romania, due to their low productivity, many sites had been afforested by pines or black locust trees at the end of the 1950’s in order to raise economic value and to hinder landslides on the steep slopes. Economic expectations did not live up, thus afforested sites will increasingly be targeted for grassland restoration, especially in protected...

Restoration of a newly created inland-dune complex as a model in practice: impact of substrate, minimized inoculation and grazing

Linda Freund, Jimena Carrillo, Christian Storm & Angelika Schwabe
In Central Europe stands of the Koelerion glaucae vegetation complex are threatened and mostly highly fragmented. Knowledge about the impact of abiotic and biotic measures to restore this vegetation complex is crucial. Therefore, an inland sand dune complex (around 2 ha) was created in 2009 as a study model in the Upper Rhine Valley (Germany), which included sites with different substrate conditions as well as grazing impact and minimized inoculation with plant material. The restoration...

Diversity and ecological differentiation of mixed forest in northern Montenegro (Mt. Bjelasica) with reference to European classification

Milan Gazdić, Albert Reif, Milan Knežević, Danka Petrović, Marko Stojanović & Klara Dološ
The current state of forests as well as tree species composition in stands is the result of past de-velopment and somehow a record of all previous influences. As a base for better projections of future forest development and the development of sustainable management strategies we should recognize developmental processes in forests and understand their drivers. Mixed mountain forests in Montenegro, with an exceptionally large variation of environmental conditions, provide an excel-lent opportunity to study eastern-Mediterranean...

Phytosociological studies of Malus sylvestris in North Hesse and Upper Franconia, Germany

Helge Walentowski, Gregor Aas, Alexander Göllner, Lisa Ahl & Martin Feulner
Malus sylvestris the European crabapple, a rare and threatened small tree species, has attracted in-creasing interest since it was awarded tree of the year 2013 in Germany. In this study, we used the wide range of different habitats in Upper Franconia and North Hesse to reveal a more complete picture about its phytosociology and ecological behavior in these regions and to examine the main environmental factors which affect its distribution. We collected a data set...

Diversity and spatial structure of cryophytic-steppes of the Minusinskaya intermoun-tain basin in Southern Siberia (Russia)

Nikolai Ermakov, Alexey Larionov, Mariya Polyakova, Igor Pestunov & Yakiv P. Didukh
Cryophytic steppes in the Minusinskaya intermountain basin containing plant species that are predominantly distributed in the alpine zone such as Androsace dasyphylla, Dryas oxyodonta, Festuca sphagnicola, Kobresia myosuroides, K. filifolia, Minuartia verna, Oxytropis bracteata, Sagina saginoides, Papaver nudicaule, Patrinia sibirica, Pedicularis lasiostachys, Pulsatilla ambigua, Saussurea schanginiana, which are considered remnants of the Pleistocene vegetation. Based on 89 relevés, we classified cryophytic steppes using the Braun-Blanquet method within two phytosociological classes: Central Asian steppes of the...

Sabine Tischew, Hartmut Dierschke, Angelika Schwabe, Eckhard Garve, Thilo Heinken, Norbert Hölzel, Erwin Bergmeier, Dominique Remy & Werner Härdtle
Aiming at a better promotion of topics related to the conservation of ecosystems and plant com-munities, the board of the „Floristisch-Soziologische Arbeitsgemeinschaft (FlorSoz)” has launched the initiative to announce a “Plant Community of the Year”. Therewith we hope to raise awareness and stimulate civil society and politics in promoting more efficient conservation strategies. For the forthcoming year, we choose the oatgras meadow as Plant Community of the Year 2019. These lowland hay meadows belong to...

Phytosociological study of arable weed communities in Slovakia

Jana Májeková & Marica Zaliberová
A phytosociological survey of weed (segetal) vegetation in Slovakia was performed. A total of 508 relevés were sampled in 2002–2008. The aims of this study were to determine the actual distri-bution of the segetal communities, to analyze their floristic structure, and to evaluate their relation-ships to selected environmental factors. Thirteen plant communities of the class Stellarietea mediae were distinguished by cluster analy-sis; 11 communities were included in the subclass Violenea arvensis (Lathyro tuberosi-Adonidetum aestivalis, Consolido-Anthemidetum...

Die Einfache Mondraute (Botrychium simplex, Ophioglossaceae) in Deutschland

H. Wilfried Bennert, Irmgard Sonneborn & Karsten Horn
This paper provides a brief portrait of Botrychium simplex and starts by describing its biological characteristics and distribution in Germany. In the third part, a demographic study is presented reporting on long-term observations of the only presently known German population (Senne area, North Rhine-Westphalia). As with all moonworts, the spores of B. simplex germinate in the soil, and the gametophytes start developing only if they are infected by an arbuscular mycorrhizal symbiont. The sporophytes are...

Goat paddock grazing improves the conservation status of shrub-encroached dry grasslands

Daniel Elias, Norbert Hölzel & Sabine Tischew
European dry grasslands are predominantly semi-natural communities. Commonly, they have been used as pastures for sheep and goats. Due to their richness in biological diversity and the large number of threatened species, they are recognized as being of high conservation value. However, in the last few decades, a dramatic decline in dry grassland areas has been observed throughout Europe. Pasture abandonment followed by grass and shrub encroachment are the main causes of dry grass-land loss,...

Effect of phenology, nutrient availability and windthrow on flowering of Allium ursinum – results from long-term monitoring and experiments

Steffi Heinrichs, Hartmut Dierschke, Thomas Kompa & Wolfgang Schmidt
Allium ursinum, a dominant herb layer species in nutrient rich, deciduous forests of Central Eu-rope, has considerably expanded in the past decades. As this species mainly relies on regeneration by seeds, we wanted to analyse if and how the timing of phenological phases, climatic factors and resource availability correlated with flowering intensity as a potential factor for its success. We rec-orded annual inflorescence numbers in a population of the Göttinger Wald from 1981 until 2017...

Flora und Vegetation der Lengder Burg im Göttinger Wald – Ein Hotspot der Phytodiversität und seine Veränderungen seit 1950

Wolfgang Schmidt & Steffi Heinrichs
Steilhänge der Mittelgebirge weisen eine kleinräumige standörtliche Vielfalt auf und wurden aufgrund ihrer exponierten Lage bereits frühzeitig durch den Menschen u. a. als Befestigungsanlage genutzt. Daraus resultierte häufig eine hohe floristische und vegetationskundliche Diversität mit hohem Naturschutzwert. Durch Umwelt- und Nutzungsveränderungen hat sich aber auch an diesen Standorten in den letzten Jahrzehnten ein starker Wandel vollzogen. Durch Auswertung alter Floren-listen und Vegetationsaufnahmen und durch aktuelle Erhebungen wollen wir die Vegetationszusam-mensetzung der Lengder Burg, eines Steilhangs...

A re-visitation study (1948–2015) of wet grassland vegetation in the Stedinger Land near Bremen, North-western Germany

Anneke Immoor, Dietmar Zacharias, Josef Müller & Martin Diekmann
Wet grasslands once covered a large area in the lowlands of northern Germany, but have declined since several decades as a result of land use intensification. Permanent plot data from such grasslands in the region that would allow to assess the extent of changes in species composition and richness are still rare. Here, we present a revisitation study of 52 quasi-permanent plots from the Stedinger Land area in the basin of the river Weser near...

Environmental drivers of species composition and richness in dry grasslands of northern and central Bohemia, Czech Republic

Kristina Merunková, Zdenka Preislerová & Milan Chytrý
Central European dry grasslands are remarkably diverse plant communities that occur at the western edge of the Eurasian forest-steppe zone and harbour many species of continental distribution. Although their plant community types have been described in detail, the diversity patterns and their environmental determinants are still poorly known for these grasslands. Here, we study environmental drivers of species composition and richness in dry grasslands of northern Bohemia (České středohoří Mts) and central Bohemia (Křivoklát region),...

Distribution and seed production of the rare, dry grassland specialist Sternbergia colchiciflora (Amaryllidaceae) in Pannonian cemeteries

Attila Molnár V., András Mészáros, András István Csathó, Gábor Balogh, Attila Takács, Viktor Löki, Ádám Lovas-Kiss, Jácint Tökölyi, Lajos Somlyay & Norbert Bauer
Despite huge habitat losses caused by agricultural intensification, dry grasslands still represent one of the most diverse ecosystems in Europe. Their highly fragmented remnants are often pre-served in man-made or human-influenced habitats (e.g., kurgans, roadside verges or cemeteries). In recent decades the significance of cemeteries as suitable habitats for preserving native and rare spe-cies has been repeatedly emphasized. However, the effect of modern management practices on long-term persistence of grassland species has remained largely unexplored....

Do short-lived ruderal and arable weed communities reflect regional climate differences? A case study from SE Styria

Verena Denk & Christian Berg
The Feldbach district is situated near the town of Feldbach in the southeastern province of Styria, Austria. Since 2007, a climate observation network of 151 climate stations within an area of approximately 20 x 15 km (grid cell 1.4 × 1.4 km) has provided a unique collection of spatial and temporal meteorological data. Examining short-lived ruderal and arable weed communities, we search for correlations and spatial patterns between the community composition and climate data. Do...

The influence of the Eastern migration route on the Slo-vak flora – a comparison after 40 years

Vladimír Jehlík, Marica Zaliberová & Jana Májeková
Transport is an important source of introduction and spread of alien plants into new areas and countries. This study provides comprehensive research of selected railway localities in South-Eastern Slovakia to determine the influence of the Eastern Migration Route on the Slovak flora. Railway trans-shipment yards in Čierna nad Tisou, Dobrá, Veľké Kapušany and Maťovce were studied from 1964 to 2013; with historic data sampled 1964–1998 and recent data sampled 2012–2013. These data sets were compared...

Flechtenreiche Kiefernwälder in Bayern: Entwicklung und Zukunft

Anton Fischer, Barbara Michler, Hagen S. Fischer, Gerhard Brunner, Simon Hösch, Arnulf Schultes & Peter Titze
During the past centuries Central European lichen pine forests were wide spread in Bavaria main-ly on sandy acidic soils, especially around the city of Nürnberg and in the mountain ranges in the east of Bavaria. Because this forest type is considered to be endangered we asked the following questions: (1) Did the species composition of this forest type change during the past decades and if yes, how? (2) Did the area covered by this forest...

Waldvegetation der Sassau im Walchensee: Vergleich von Naturwald und Wirtschaftswald, Insel und Halbinsel

Jörg Ewald & Udo Endres
Forest stands, vegetation and soils of the strict forest reserve (NWR, designated in 1978) Sassau, an island of 2.6 ha situated in the alpine lake Walchensee, were surveyed on 20 permanent plots and compared to a neighbouring forest under customary management (WW). Both forests are situated on karstic limestone plateaus, 800–830 m a.s.l. under cool and moist climate (6.2 °C, 1483 mm) of the lower montane belt. With 48 m² and 450 m³*ha-1, NWR had...
