In Hungary a countrywide vegetation mapping project carried out between 2003 and 2006 provided immense, detailed data on the current status of the forest-steppe vegetation (MÉTA database). In addition, two fundamentally important historical sources from the late eighteenth century have been analyzed recently. Using these sources we reconstruct and...

The mutual dependence of extensive land-use and conservation management has become apparent in Europe in the last 20–30 yr. Extensive land-use often survives in protected areas only, in the form of conservation management. Knowledge of extensive herding and that of conservation management are parts of two knowledge systems (traditional and scientif...

Habitat loss is a key driver of biodiversity loss. However, hardly any long-term time series analyses of habitat loss are available above the local scale for finer-level habitat categories. In this paper we analyse, from a long-term perspective, the habitat specificity of habitat area loss, the change in trends since the fall of communism and the i...

Many people call for strengthening knowledge co-production between academic science and indigenous and local knowledge systems. A major barrier to cooperation seems to be a lack of experience regarding where and how traditional knowledge can be found and obtained. Our key question was whether the expert judgment of academic zoologists or a feature-...

The research gap between rangeland/livestock science and conservation biology/vegetation ecology has led to a lack of evidence needed for grazing‐related conservation management. Connecting scientific understanding with traditional ecological knowledge of local livestock keepers could help bridge this research and knowledge gap. We studied the graz...

The Biebrza Valley is one of the largest wetland ecosystems in Central Europe to host species of convervation relevance, and features a strongly biocultural character. The semi-natural habitats that dominate its landscape have been developed as a result of centuries-long regimes of traditional grazing and haymaking. Starting in the 1960s, the gradu...

Ecosystems and landscapes shaped by the intricate relationship between people and their natural environment embody the impact of many different past land‐use practices and historical events. However, in some regions, classical historical records of landscape change do not exist or are insufficiently detailed. Local communities' ecological memory ca...

Evidence‐based conservation can benefit substantially from multiple knowledge sources and different knowledge systems. While traditional ecological knowledge (TEK) and collaborative research are increasingly acknowledged, detailed cross‐knowledge system reviews are scarce and their methodology underdeveloped. We have two objectives: to prepare such...

Free-range domestic pig keeping in forests is a millennia-old practice in Eurasia, and remains common in many silvopastoral systems worldwide. Despite the long history of its potential impact on forests, the influence of this practice on the structure, composition and species richness of the understorey is hardly known. We studied the impact of fre...

Locals engaged in traditional farming and possessing traditional ecological knowledge consider certain species worthy of protection, as do official nature conservationists, although the sets of taxa may not be identical. Exploring the relationship between the two sets of taxa could bring many practical benefits, yet the literature on this subject i...

While ethnobiology is a discipline that focuses on the local, it has an outstanding, but not yet fully realized potential to address global issues. Part of this unrealized potential is that universalistic approaches often do not fully recognize culturally grounded perspectives and there are multiple challenges with scaling up place-based research....

Indigenous and traditional practices based on ethnoecological knowledge are fundamental to biodiversity stewardship and sustainable use. Knowledge partnerships between Indigenous Peoples, traditional local communities, and ecologists can produce richer and fairer understandings of nature. We identify key topical areas where such collaborations can...

The existing plant trait databases’ applicability is limited for studies dealing with the flora and vegetation of the eastern and central part of Europe and for large-scale comparisons across regions, mostly because their geographical data coverage is limited and they incorporate records from several different sources, often from regions with marke...

The prevailing paradigm about the Quaternary ecological and evolutionary history of Central European ecosystems is that they were repeatedly impoverished by regional extinctions of most species during the glacial periods, followed by massive recolonizations from southern and eastern refugia during interglacial periods. Recent literature partially c...

The species-rich natural and seminatural grasslands of East-Central Europe have long offered diverse forages and fodder species for domestic livestock. The use and perception of forage and fodder plants are influenced by various agricultural, environmental, sociocultural, technical, and political factors. In our paper, we compared four indicator se...

Along small watercourses, the growth and renewal of native willows and poplars (Sali-caceae species) are hindered by the effects of past and recent man-made landscape alteration and climate change, while the selective foraging of the beaver (Castor fiber) is also becoming an increasingly important driver. Knowledge about foraging decisions can refi...

Vegetation-based landscape classifications reflecting combinations of different vegetation types promote the understanding of landscape patterns and ecological restoration. However, widespread landscape classifications containing a single thematic resolution may oversimplify landscape patterns. This study aimed at providing a solution for and testi...

An understanding of traditional ecological knowledge systems is increasingly acknowledged as a means of helping to develop global, regional and national, but locally relevant policies. Pastoralists often use lands that are unsuitable for crops due to biophysical and climatic extremities and variabilities. Forage plants of pastures are utilized by h...

We present PADAPT 1.0, the Pannonian Database of Plant Traits which relies on regional data sources and integrates existing data and new measurements on a wide range of traits and attributes of the plant species of the Pannonian Biogeographical Region and makes it freely accessible at www.padapt.eu. The current version covers the species of the reg...

Effective policies to halt biodiversity loss require knowing which anthropogenic drivers are the most important direct causes. Whereas previous knowledge has been limited in scope and rigor, here we statistically synthesize empirical comparisons of recent driver impacts found through a wide-ranging review. We show that land/sea use change has been...

Restoration prioritization helps determine optimal restoration interventions in national and regional spatial planning to create sustainable landscapes and maintain biodiversity. Here we investigate different forest-steppe vegetation types in the Pannonian sand region to provide restoration recommendations for conservation management, policy and re...

Traditional agroforestryAgroforestry systems such as wood pasturesWood pasture have been a widespread land-use type across Europe for thousands of years. Today, demand for healthy and organic food is growing. AgroforestryAgroforestry systems, which are based on traditional land-uses, could be a promising way to address this issue. In order to facil...

Herbivore species can either hinder or accelerate the invasion of woody species through selective utilization. Therefore, an exploration of foraging decisions can contribute to the understanding and forecasting of woody plant invasions. Despite the large distribution range and rapidly growing abundance of beaver species across the Northern Hemisphe...

Despite deforestation taking place globally, forest cover is increasing in many European landscapes. This increase, however, resulting from plantations and spontaneous forest regrowth, may obscure the generally declining trend of semi-natural forests, though the latter are essential for local and landscape-level conservation strategies and sustaina...

Background The Biebrza Valley is one of the largest complexes of wetlands (floodplain and percolation mire) and conservation sites in Central Europe. Local communities have managed the area extensively for subsistence and farming purposes for centuries; nonetheless, since the 1960s, hand mowing and livestock grazing have been gradually ceasing due...

Traditional ecological knowledge enables pastoralists to cope with social-ecological changes, thereby increasing the sustainability of their practices and fostering social-ecological resilience. Yet, there is a significant knowledge gap concerning the extent to which pastoral traditional ecological knowledge has changed over time at the global leve...

Micro-scale management of cultural landscapes with species-rich grasslands requires the operation of extensive, traditional land-use systems. These social-ecological systems are under increasing pressure of interacting drivers that impact on farmers' individual decisions and force them to make trade-offs. We aimed to reveal the local understanding...

One of the main goals of the EU Biodiversity Strategy for 2030 is to avoid further loss of biodiversity and to restore ecosystems. These efforts can be facilitated by compiling the main research topics related to conservation biology to provide new evidence for the most urgent knowledge gaps, and publicise it to researchers, research funders and po...

High-resolution ecosystem maps increase the efficiency of policy implementation. However due to challenges related to both data and methods, such maps of appropriate scale and quality are still rarely available for nationwide analyses. We present solutions to some typical challenges of national-scale ecosystem mapping through the new Ecosystem Map...

The knowledge, values, and practices of Indigenous peoples and local communities offer ways to understand and better address social-environmental problems. The article reviews the state of the literature on this topic by focusing on six pathways by which Indigenous peoples and local communities engage with management of and relationships to nature....

Background Traditional knowledge is key for sustainability, but it is rapidly disappearing. Pig keeping in forests and marshes is an ancient, once widespread, now vanishing practice, with a major economic and ecological potential. The knowledge of pig keepers and the foraging activity of pigs are hardly documented. Methods We studied the knowledge...

Background : The concept of potential natural vegetation (PNV) embodies mature vegetation capable to survive under the environmental conditions of a site. Despite its widespread use, its applicability under the current level of human impacts on the environment has been criticised. Aims : We re-examine the original publication of the PNV concept an...

Background: Documenting local ecological knowledge (LEK) has recently became a topic of considerable interest. LEK can contribute to various areas of ecology, including habitat management and conservation biology. It has been recently revealed that recreational fishers’ ecological knowledge (FEK) can also provide valuable information about differen...

Aims Understanding fine-grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of fine-grain richness values of Palaearctic open habitats for vascular plants, bryophytes, lichens and complete vegetation (i.e., the sum of the...

“Nature's contributions to people” (NCP) is designed to provide space for the recognition of diverse and evolving culturally mediated ideas about what people derive from, and co-produce with, nature. Its origins, along with the IPBES conceptual framework in which it is embedded, is transdisciplinary, action-oriented, and inclusive and also embraces...

The high nature conservation value of floodplain ecosystems is severely threatened by invasive alien species. Besides adversely affecting native biodiversity, these species also pose a major threat from a wider socio-ecological perspective (e.g. ‘roughness’ increases flood risk). Finding options to control dense shrub layers consisting of invasive...

ABSTRACT. Recently, climate change has had a considerable impact on rangelands, available forage, and shifting boundaries of ecological zones in Mongolia. Additionally, long-term studies in the forest-steppe zone show that increasing livestock pressure impacts vegetation composition and cover. Evidence shows that the traditional ecological knowledg...

Today’s Mediterranean landscapes result from the interaction between ecosystems and anthropogenic activities. This study aims to assess how the land-use changes between the mid-nineteenth and end of the twentieth century influenced the temporal continuity of the ecosystems in central Apennines (central Italy). Information was acquired from Gregoria...

Ecologists and conservationists increasingly acknowledge that traditional ecological knowledge (TEK) is vital for a better understanding and conservation of biodiversity; for example, for a more complex socioecological understanding of long-term processes, ecosystem resilience, the impacts of traditional management practices, and the worldviews und...

The Convention on Biological Diversity is defining the goals that will frame future global biodiversity policy in a context of rapid biodiversity decline and under pressure to make transformative change. Drawing on the work of Indigenous and non-Indigenous scholars, we argue that transformative change requires the foregrounding of Indigenous people...

Background: Scientists frequently raise the topic of data deficiency related to the abundance and distribution of macrofungi in the context of climate change. Our study is the first detailed documentation on locals' perception of fungal ecology which covers a large mycophilous region of Europe (Mazovia, Poland). Methods: A total of 695 semi-struc...

A tölgylisztharmat (Erisyphe spp.) a tölgyek (különösen a kocsányos tölgy) erdész szakma által jól ismert kórokozója. Az európai növénykórtan és erdészettudomány is hatalmas tudást halmozott már fel arról, hogy milyen károkat képes okozni csemetekertekben, tarvágás vagy fokozatos felújító vágást követõ felújításokban, pótlá- sokban vagy éppen fiata...

European countries are far from the 15% restoration target to be reached by 2020, partly due to the lack of large-scale studies at the national level that would help prioritize restoration efforts. We investigated the regeneration capacity and the determining environmental factors at the national level for three Pannonian sandy habitat types. The a...

Introduced pathogen microorganisms are important drivers of ecosystem change. This paper highlights the impact of the non-native pathogen mildew multi-species complex on the natural regeneration dynamics of pedunculate oak (Quercus robur). Pedunculate oak is a European keystone tree species, hosting a great amount of biodiversity, but its future ro...

Indigenous Peoples’ lands cover over one‐quarter of Earth's surface, a significant proportion of which is still free from industrial‐level human impacts. As a result, Indigenous Peoples and their lands are crucial for the long‐term persistence of Earth's biodiversity and ecosystem services. Yet, information on species composition on these lands glo...

Including local and indigenous knowledge in the work of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Global Assessment: Outcomes and lessons for the future.

Species reintroductions aim to re-establish populations of locally extinct, often keystone species. As a consequence of the reintroduction and protection of the Eurasian beaver (Castor fiber), the species has recolonized the suitable habitats (including floodplains) across Europe in the past few decades. Floodplain habitats have already been signif...

We examined the knowledge of local nature conservationists and researchers associated with the Eurasian beaver through interviews. In the first part of our study (Juhász et al. 2019), we reported the spread of the beaver, recognisable beaver signs, possibilities of human-beaver coexistence and causes of mortality. In the second part (present paper)...

Background Forests have been grazed for millennia. Around the world, forest grazing by livestock became a controversial management practice, gradually restricted in many countries over the past 250 years. This was also the case in most Central and Eastern European countries, including Hungary, where forest grazing was a legally prohibited activity...

Wetland grazing by livestock, once widespread throughout Europe, is increasingly used in conservation management. To avoid conflicts and enable cooperation between wetland users and conservationists, habitat quality indicators relevant to both stakeholder groups would be useful. We aimed to identify which indicators of grazed wetland habitat qualit...

Broader understanding of stakeholders' perceptions of landscape changes is needed to cope with global environmental challenges locally. In this study, farmers' and conservationists'-researchers' perceptions of landscape changes were compared by analyzing interviews conducted in the Danube-Tisza Interfluve region of Hungary through a combined quanti...
