Cím:Legacies of past land use challenge grassland recovery : An example from dry grasslands on ancient burial mounds / Balázs Deák, Orsolya Valkó, Csaba Albert Tóth, Ágnes Botos, Tibor József Novák

Megjegyzések:Due to large-scale agricultural intensification, grasslands are often restricted to habitat islands in humantransformed landscapes. There are approximately half a million ancient burial mounds built by nomadic steppic tribes in the Eurasian steppe and forest steppe zones, which act as habitat islands for dry grassland vegetation. Land use intensification, such as arable farming and afforestation by non-native woody species are amongst the major threats for Eurasian dry grasslands, including grasslands on mounds. After the launch of the Good Agricultural and Environmental Condition framework of the European Union, in Hungary there is a tendency for ceasing crop production and cutting non-native woody plantations, in order to conserve these unique landmarks and restore the historical grassland vegetation on the mounds. In this study, restoration prospects of dry grassland habitats were studied on kurgans formerly covered by croplands and Robinia pseudoacacia plantations. Soil and vegetation characteristics were studied in the spontaneously recovering grasslands. The following questions were addressed: 1; How does site history affect the spontaneous grassland recovery? 2; Do residual soil nutrients play a role in grassland recovery? In former croplands, excess phosphorus, while in former Robinia plantations, excess nitrogen was present in the soil even four years after the land use change and grassland vegetation was in an early or midsuccessional stage both on the mounds. The results showed that, without proper management measures, recovery of grassland vegetation is slow on mounds formerly used as cropland or black locust plantation. However, restoration efforts, focused on the restoration of mounds formerly covered by croplands, can be more effective compared to the restoration of mounds formerly covered by forest plantations.

Cím:Cultural heritage and biodiversity conservation - plant introduction and practical restoration on ancient burial mounds / Valkó Orsolya, Tóth Katalin, Kelemen András, Miglécz Tamás, Radócz Szilvia, Sonkoly Judit, Tóthmérész Béla, Török Péter, Deák Balázs

Megjegyzések:Linking the conservation of cultural heritage and natural values provides a unique opportunity for preserving traditional landscapes and receives an increased awareness from stakeholders and society. Ancientburial mounds are proper objects of such projects as they are iconic landscape elements of the Eurasiansteppes and often act as refugia for grassland specialist species. The aim of this project was to reintroducegrassland plant species to burial mounds for representing them as cultural monuments with the associatedbiodiversity for the public. The effectiveness of seed sowing, transplanting greenhouse-grown plantsand individuals from threatened populations on burial mounds in Hortobágy National Park, Hungarywas tested. The following questions were answered: (1) which method is the most effective for speciesintroduction? (2) which species can establish most successfully? (3) how does management affect thespecies establishment rates? It was found advisable to use a combination of seed sowing and transplantinggreenhouse-grown plants. Sowing was found as a cost-effective method for introducing large-seededspecies, whilst introduction of greenhouse-grown transplants warranted higher establishment rates for alarger set of species. Transplanting adult individuals was more reliable regardless of management regimes,however this method is labour-intensive and expensive. Intensive management, like mowing with heavymachinery and intensive grazing, should be avoided in the first few years after introduction. The authors highlighted the fact that introducing characteristic grassland species on cultural monuments offers a greatopportunity to link issues of landscape and biodiversity conservation. This project demonstrated that, bythe revitalisation of cultural monuments, cultural ecosystem services can also be restored.
