Abstract Our study investigates the negative impact of nitrogen (N) deposition on species richness in acidic grasslands, based a temporal comparison vegetation data spanning period almost 70 years. We compiled large base plots assigned to Violion caninae grassland type, composed managed, but unfertilized semi‐natural grasslands nutrient‐poor, soils. In total 1114 plots, mainly from Great Britain, Netherlands and Germany, were compiled, dating back 1939. Environmental site information...
Abstract Context Most protected areas are managed based on objectives related to scientific ecological knowledge of species and ecosystems. However, a core principle sustainability science is that understanding including local knowledge, perceptions ecosystem service provision landscape vulnerability will improve resilience social-ecological systems. Here, we take up these assumptions in the context provide insight effectiveness nature protection goals, particularly highly human-influenced...
Abstract Questions Has plant species richness in semi‐natural grasslands changed over recent decades? Do the temporal trends of habitat specialists differ from those generalists? there been a homogenization grassland vegetation? Location Different regions Germany and UK. Methods We conducted formal meta‐analysis re‐survey vegetation studies grasslands. In total, 23 data sets were compiled, spanning up to 75 years between surveys, including 13 wet grasslands, six dry four other types. Edaphic...
Abstract Question: (i) How do species richness and turnover change along a pH gradient? (ii) What are possible driving factors behind these patterns? (iii) Can the observed patterns be explained by an individualistic continuum concept that postulates independence of responses constant rates? Location: Semi‐natural, deciduous hardwood forests in NW Germany (558 plots). Methods: The instantaneous rate compositional is measured sum slope angles modelled response curves (119 understorey species)...
Implementing the European Green Deal and transforming agricultural practices requires a wider amplified policy toolbox. As many sustainability considerations are context-dependent, there is need for instruments, which take individual characteristics of production landscapes into account. Food products with particularly strong relationship to their landscape origin can be marketed under “Protected Designation Origin” label (PDO). In this article, we analyze synergies between PDO regional...
Abstract Questions Which trends and patterns of community change occurred in Nardus grasslands over recent decades parts the Continental biogeographic region Germany? Are consistent across two study regions? Do impacts environmental changes on Central Europe correspond to those identified European Atlantic region? Location East Hesse Highlands, Germany. Methods In 2012–2015, we re‐surveyed quasi‐permanent plots that had been initially surveyed between 1971 1987, re‐measured soil parameters....
Abstract Question: Predictive models in plant ecology usually deal with single species or community types. Little effort has so far been made to predict the composition of a explicitly. The modelling approach presented here provides conceptual framework on how achieve this by combining habitat for large number an additive model. Our is exemplified Nardus stricta communities (acidophilous, low-productive grassland). Location: Large areas Germany, 0-2040 m a.s.l. Methods: Logistic regression...
Abstract Vegetation-plot resurvey data are a main source of information on terrestrial biodiversity change, with records reaching back more than one century. Although and from re-sampled plots have been published, there is not yet comprehensive open-access dataset available for analysis. Here, we compiled harmonised vegetation-plot Germany covering almost 100 years. We show the distribution plot in space, time across habitat types European Nature Information System (EUNIS). In addition,...

Abstract Question: Species optima or indicator values are frequently used to predict environmental variables from species composition. The present study focuses on the question whether predictions can be improved by using amplitudes instead of single representing optima. Location: Semi‐natural, deciduous hardwood forests northwestern Germany. Methods: Based a data set 558 relevés, responses (presence/absence) pH were modelled with Huisman‐Olff‐Fresco (HOF) regression models. derived response...
Abstract Questions Vegetation resurveys, both single studies and meta‐analyses, have predominantly been based on vascular plant data while bryophytes lichens largely neglected. Our study aims to fill this gap addresses the following research questions: has overall species richness of terricolous in forests changed over time? Which are winners losers among ecological groups? Do results give a signal impact nutrient enrichment, changes light regime climate change? Location Deciduous coniferous...
Abstract Questions What are the driving factors for species richness of understorey herbs isolated forest patches? How can relative direct and indirect effects patch area, site quality, habitat isolation continuity be disentangled? on different groups? Location Eutrophic hardwood patches in northwestern Germany. The these results from extensive agricultural land use prevailing poor soil conditions surrounding landscape. Thus, embedded within a matrix both open habitats species‐poor acidic...
We carried out vegetation studies in the ancient Hasbruch forest, which provided unique conditions of unmanaged (UM) and managed (M) stands two types Stellario-Carpinetum loniceretosum (POOR) stachyetosum (RICH) one closed forest allowing us to study (1) changes species composition richness over 20 years considering entire as well (2) group-specific changes. lowlands Lower Saxony, Germany. In 2016 we resurveyed vascular plant 79 semi-permanent plots analysed 1996. General trends drivers were...
Abstract Question: The eu‐atlantic forest herb Ceratocapnos claviculata showed a recent increase in frequency within its native range and an eastward northward expansion Central Europe. To gain deeper understanding of factors affecting the species, we analyzed vegetation relevés at three different scales asked following questions: As species occurs wide types, is variation community composition across entire related to climatic environmental zones tree cover? Are there differences habitat...
Abstract Questions Mountain grasslands can be strongly affected by extreme droughts such as those related to climate change. What are the impacts of on community composition, diversity, Ellenberg indicator scores and species groups in oligotrophic montane Nardus grasslands, what associated mechanisms vegetation change? Location Rhön Mountains, Germany. Methods Over three consecutive years, we investigated effects yearly (April–August) an experimental setup with rainout shelters. Owing...
The Vegetation Database Forests of the Oldenburg Region (GIVD ID EU-DE-010) contains numerous forest releves from surrounding area within a radius ca.50 km.These relevés originate several studies conducted by scientists and students University since 1990.A high proportion includes information on pH humus form.The are mostly unpublished but results have led to publications especially role in shaping floristic patterns communities.
