<scp>ReSurveyEurope</scp>: A database of resurveyed vegetation plots in Europe

AbstractAimsWe introduce ReSurveyEurope — a new data source of resurveyed vegetation plots in Europe, compiled by a collaborative network of vegetation scientists. We describe the scope of this initiative, provide an overview of currently available data, governance, data contribution rules, and accessibility. In addition, we outline further steps, including potential research questions.ResultsReSurveyEurope includes resurveyed vegetation plots from all habitats. Version 1.0 of ReSurveyEurope contains 283,135 observations (i.e., individual surveys of each plot) from 79,190 plots sampled in 449 independent resurvey projects. Of these, 62,139 (78%) are permanent plots, that is, marked in situ, or located with GPS, which allow for high spatial accuracy in resurvey. The remaining 17,051 (22%) plots are from studies in which plots from the initial survey could not be exactly relocated. Four data sets, which together account for 28,470 (36%) plots, provide only presence/absence information on plant species, while the remaining 50,720 (64%) plots contain abundance information (e.g., percentage cover or cover–abundance classes such as variants of the Braun‐Blanquet scale). The oldest plots were sampled in 1911 in the Swiss Alps, while most plots were sampled between 1950 and 2020.ConclusionsReSurveyEurope is a new resource to address a wide range of research questions on fine‐scale changes in European vegetation. The initiative is devoted to an inclusive and transparent governance and data usage approach, based on slightly adapted rules of the well‐established European Vegetation Archive (EVA). ReSurveyEurope data are ready for use, and proposals for analyses of the data set can be submitted at any time to the coordinators. Still, further data contributions are highly welcome.</jats:sec

Vegetation of fir- and calcicolous beech forests of the Czech Republic

Boublík K. (2009): Vegetation of fir- and calcicolous beech forests of the Czech Republic. - Ms., 104 p. [PhD thesis; depon. in: Library of the Department of Botany, Faculty of Sciences, Charles University, Prague] The thesis proposes Braun-Blanquet phytosociological classification of calcicolous beech forests and fir forests of the Czech Republic. Calcicolous forests dominated by Fagus sylvatica (Fagion, Cephalanthero-Fagenion) were defined with the help of two approaches: (i) selection on the basis of correspondence of species composition with an expert delimited species group and (ii) the formalized and supervised Cocktail method. In the case of the Cocktail method, the definitions of associations were created by combinations of sociological species groups using logical operators. Dominance of single species was included in the definitions of associations. Only one association (Cephalanthero-Fagetum) was distinguished. This association usually occurs on limestone, calcareous sandstone and calcareous sandy marlite. However, it can be found also on basalt and phonolite. TWINSPAN analysis distinguished three vegetation types within Czech calcicolous beech forests which are interpreted as subassociations of Cephalanthero- Fagetum: (i) Cephalanthero-Fagetum seslerietosum caeruleae occurring on..

Vegetation and geobiocoenological classification of silver fir forests of the Czech Republic – preliminary results

Preliminary results of vegetation classification of silver fir (Abies alba) forests are given. Seven communities from three alliances were distinguished in the Czech Republic. Climax stage of vegetation on the habitats of each association was investigated by geobiocoenological methods. It is claimed, that fir forests are seminatural that originated by stronger human impact (incl. fir forests on pseudogleys). They depend on forest grazing, litter raking, and other forest management. Fagus sylvatica is supposed to be dominant or frequent tree under natural conditions

Potential natural vegetation of the model transect in Třeboň basin (South Bohemia, Czech Republic)

The paper deals with preliminary results of reconstruction vegetation mapping based on geobiocoenological principles (soil, climatic and growth conditions) and published palynological studies from the study area. On the basis of occurrences and growth features of climax trees (especially Fagus sylvatica and Abies alba) and published palynological studies, I suppose lower potential occurrence of Pinus sylvestris and Quercus robur in contrary to existing reconstruction maps (maps of reconstructed natural vegetation, potential natural vegetation and forest site maps). In these maps, proportion of Fagus sylvatica is probably underestimated. I assume potential occurrence of beech forests or forests with a great proportion of beech also on dystric cambisols and podzols developed from gravel sand of pleistocene alluvial terraces or on pseudogleys

Die Pflanzengesellschaften der Tannenwälder in Südost-Böhmen

The vegetation of silver fir forests in southeastern Bohemia (Czech Republic) was studied using the Braun-Blanquet approach. On the basis of 57 phytosociological relevés, three associations were subjectively distinguished: (1) oligotrophic Vaccinio vitis-idaeae-Abietetum, (2) oligo-mesotrophic Luzulo luzuloidis-Abietetum, and (3) mesotrophic Galio rotundifolii-Abietetum (all of them with drier and wetter subtypes). Each association is characterised by species composition, basic soil properties (soil type, humus form), and distribution in the study area. Ellenberg indicator values and detrended correspondence analysis were used to visualize the similarity of vegetation types and detect the main ecological factors determining the proposed classification. The syntaxonomy of fir-dominated forests is discussed.Die Vegetation der Tannenwälder wurde in Südost-Böhmen (Tschechien) mit Hilfe des Braun-Blan-quet-Ansatzes untersucht. Drei Assoziationen von Tannenwäldern wurden subjektiv unterschieden, basierend auf 57 Vegetationsaufnahmen: (1) das Vaccinio vitis-idaeae-Abietetum auf oligotrophen Standorten, (2) das Luzulo luzuloidis-Abietetum auf oligo-mesotrophen Standorten und (3) das Galio rotundifolii-Abietetum auf mesotrophen Standorten (alle mit bodentrockeneren und -feuchteren Untereinheiten). Jede Assoziation wird mit Artenkombination, Bodeneigenschaften und Verbreitung im Untersuchungsgebiet beschrieben. Ellenberg-Zeigerwerte und Ordinationsmethoden werden verwendet, um die Ähnlichkeit der Vegetationstypen und die für die Vegetation wichtigen Umweltfaktoren darzustellen. Die Syntaxonomie der Tannenwälder wird diskutiert

Auswirkung des Schalenwildes und der Wetterbedingungen auf die Vegetation der gefährdeten Trockenrasen im Biosphärenreservat Křivoklátsko (Tschechische Republik)

Using four exclosures, the impact of mouflon grazing and weather on plant communities of the phytosociological alliances Koelerio-Phleion phleoidis and Hyperico perforati-Scleranthion perennis occurring on shallow soils within a forest landscape was studied in the Křivoklátsko Biosphere Reserve (Czech Republic) during seven years. In the years 2004–2010, the vascular plant species composition was recorded annually on a total of eight fenced and eight control plots, each 2 m × 1 m in size. Treatment, time, and weather data were used as explanatory variables in ordination and correlation analyses. Cover values of different life forms and indicator values varied significantly in dependence on the weather conditions of the preceding five months; however, correlations varied according to the vegetation type and were rather rarely detected. The effect of fencing appeared important in all study plots; however, the temporal trends were significant only in half of them. We did not find a significant interaction between treatment and time in the total dataset. A successional change was detected in one fenced plot only; in all other cases, the species composition fluctuated – a phenomenon that is not directly attributable to weather conditions. In the fenced plots, the herbaceous vegetation cover decreased, mainly due to litter accumulation and partly due to shrub encroachment. At least some parts of the valuable and species-rich habitats could be maintained under high game density, but some parts are endangered by eutrophication and game grazing. Nature conservation management should balance both mechanisms.Die Auswirkungen von Mufflonbeweidung und Wetterbedigungen auf Pflanzengesellschaften der Verbände Koelerio-Phleion phleoidis und Hyperico perforati-Scleranthion perennis auf flachgründigen Böden innerhalb einer Waldlandschaft wurden im Biosphärenreservat Křivoklátsko (Pürglitzer Wald), Tschechische Republik, in vier Auszäunungen untersucht. Von 2004 bis 2010 wurde die Artenzusammensetzung der Gefäßpflanzen jährlich auf je acht Plots (2 m × 1 m) innerhalb und außerhalb der Auszäunung erfasst. Beweidung und Wetterdaten wurden als erklärende Variablen für Ordinations- und Korrelationsanalysen verwendet. Die Deckung verschiedener Lebensformen sowie Indikatorwerte schwankten signifikant in Abhängigkeit von den Wetterbedingungen der vorhergehenden fünf Monate. Die Auszäunung hatte nur bei einer Untersuchungsfläche einen wesentlichen Einfluss auf die Artenzusammensetzung. In den Auszäunungen nahm die Deckung der krautigen Vegetation kontinuierlich ab, teilweise bedingt durch Verbuschung und Streuakkumulation. Wir schließen, dass ein Teil der wert - vollen und artenreichen Habitate auch unter einem erhöhten Wildbesatz erhalten werden kann, wobei allerdings die Gefahr von Eutrophierung und Wildverbiss besteht. Das Naturschutzmanagement sollte diese beiden Einflüsse gegeneinander abwägen
