Cím:Better safe than sorry - Understanding the attitude and habits of drivers can help mitigating animal-vehicle collisions / Sándor Borza, Laura Godó, Orsolya Valkó, Zsolt Végvári, Balázs Deák
Dátum:2023
ISSN:0301-4797
Megjegyzések:The rapidly growing global road networks put serious pressures on terrestrial ecosystems and increase the number and severity of human-wildlife conflicts, which in most cases manifest in animal-vehicle collisions (AVCs). AVCs pose serious problems both for biodiversity conservation and traffic safety: each year, millions of vertebrates are roadkilled globally and the related economic damage is also substantial. For a comprehensive understanding of factors influencing AVC it is essential to explore the human factor, that is, the habits and attitude of drivers; however, to date, comprehensive surveys are lacking on this topic. Here we addressed this knowledge gap and surveyed the habits of drivers and their experience and attitude towards AVCs by a comprehensive questionnaire covering a large geographical area and involving a large number of respondents (1942 completed questionnaires). We aimed to reveal how driving habits affect the chance of AVC, and explored the attitude of the drivers regarding AVC. We found that the number of lifetime AVC cases was higher for male drivers, for those who drove longer distances per year, had more driven years, used country roads or drove large vehicles. Our results showed that almost half of the drivers surveyed had experienced at least one AVC in their lifetime. Drivers' attitudes towards the importance of nature conservation or traffic safety in the aspect of AVC, and fear of collision showed a significant correlation with experienced AVC cases. Drivers' opinions indicated that the most trusted and desired AVC prevention measures were physical objects such as fences and wildlife crossings. Our research provides guidelines for developing targeted initiatives in the future to increase awareness about the significance of AVC and target those drivers who are most vulnerable to AVC.

Cím:Grassland fires in Hungary : experiences of nature conservationists on the effects of fire on biodiversity / Deák Balázs, Valkó Orsolya, Török Péter, Végvári Zsolt, Hartel Tibor, Schmotzer András, Kapocsi István, Tóthmérész Béla
Dátum:2014

Megjegyzések:Fire as a natural disturbance has been present in most European grasslands. Controlled burning was also an important component of the traditional landscape management for millennia. It was mainly used to reduce litter and woody vegetation and to maintain open landscapes suitable for farming. Due to socio-economical changes traditional and sustainable use of fire was ceased and replaced by arsons and technical fires in Europe. Despite its wide application in the past and the considerable extension and frequency of current grassland fires, the impact of fire on the grassland biodiversity is still scarcely documented in Europe. The aim of this study is to offer a perspective on the issue of fire impact on grasslands, by overviewing published information and practical experiences from Hungary. Our results suggest that fire can be detrimental for several taxa (e.g. insects or ground-dwelling birds), but can also promote population growth of several endangered species by reducing litter or by creating and maintaining open habitats. We also found that fire may be effective in controlling invasive plant species. The effect of fire on grassland biodiversity may be rather context-dependent. There is a critical need for developing robust evidences on the context-dependence of fire effect on biodiversity. For this, well designed prescribed burning experiments are crucial.

Cím:Effects of Land Use and Wildfires on the Habitat Selection of Great Bustard (OTIS TARDA L.) : Implications for Species Conservation / Zsolt Végvári, Orsolya Valkó, Balázs Deák, Péter Török, Sándor Konyhás, Béla Tóthmérész
Dátum:2016
ISSN:1085-3278
Megjegyzések:Increasing agricultural activities have been shown to affect soil and vegetation changes leading to serious biodiversity declines throughout the world. These effects are amplified in dry grassland areas, where resulting changes in habitat structure affect threatened animals on long temporal scales. Great bustards (Otis tarda) inhabit open landscapes where fire and grazing have been a part of the natural disturbance regime since historical times. Even fire and grazing are hypothesized to be important factors in the lifecycle of the species, studies are still missing on disturbance-related lekking distribution patterns of great bustards. We analyzed the importance of fires and grazing on the spatial distribution of lekking bustards controlling for habitat types, habitat diversity, distance from roads and social effects. Our standardized dataset spanned 31 years, being one of the largest datasets on bustard lekking. During the 31 years we observed 10 118 individuals at 639 observation points in Hortobágy National Park, East-Hungary. One of the most important predictors for total number of birds and number of males was the area burnt in previous years. We found that increased habitat diversity had a positive effect on female numbers. Models fit on second- and third-year burn data detected no substantial role of burning on lekking distribution. Our results suggest that introduction of a patch-burning management system in lekking areas could increase the availability of optimal lek sites for bustards. As an effective management tool, we suggest applying patch-burning annually in a spatially mosaic structure inside the area occupied by each sub-population unit.

Cím:The Eurasian crane (Grus grus) as an ecosystem engineer in grasslands: Conservation values, ecosystem services, and disservices related to a large iconic bird species / Orsolya Valkó, Sándor Borza, Laura Godó, Zsolt Végvári, Balázs Deák
Dátum:2022
ISSN:1085-3278
Megjegyzések:Large bird species, such as cranes are involved in human-wildlife conflicts as they often forage in croplands. The Eurasian crane (Grus grus) is a large bird species, protected across Europe, which, thanks to conservation programmes and its ability to utilise croplands for foraging, shows a strongly increasing population trend. This exaggerates the existing conflicts between crop farmers and cranes and is spilling over to natural habitats, where foraging by large flocks can lead to land degradation. No studies have evaluated the effects of foraging cranes on grasslands, despite the fact that these habitats provide important feeding grounds for cranes across their whole range. To fill this knowledge gap, we evaluated the ecosystem engineering effect of foraging Eurasian cranes on the vegetation of dry grasslands in Hungary. We used indicators of vegetation naturalness, forage quality, and floral resource provision to evaluate the ecosystem state from multiple aspects. We sampled 100 quadrats in disturbed patches and 100 in undisturbed grasslands in two seasons and 2 years (800 observations). Cranes created distinct vegetation patches with different species composition from undisturbed areas. We identified important trade-offs between the positive and negative effects of the foraging activity of cranes on different structural and functional components of the ecosystems. The crane-disturbed early-successional patches increased plant diversity and floral resources but decreased the area of undisturbed grasslands. Although crane-disturbed patches could provide forage for livestock early in the season, the forage quality became poor later in the year. We highlight the importance of monitoring the landscape-level extent of the disturbed areas.
