Monitoring the reaction of grassland canopies on fertilizer application is of major importance to enable a well-adjusted management supporting a sustainable production of the grass crop. Up to date, grassland managers estimate the nutrient status and growth dynamics of grasslands by costly and time-consuming field surveys, which only provide low temporal and spatial data density. Grassland mapp...

Land-use and management are disturbance factors that have diverse effects on community composition and structure. In traditional rural grasslands, such as meadows and pastures, low-intensity management is maintained to enhance biodiversity. Maintenance of road verges, in turn, creates habitat, which may complement traditional rural grasslands. To evaluate the effect of low-intensity disturbance...

SOC sequestration on cropland and grassland is an important mitigation option with potentially significant cobenefits for food security. At a carbon price of 20 $/tCO2eq, Paustian et al. (2016) identified a technical mitigation potential of 3-8 GtCO2eq/yr related to improved cropland and grassland management, biochar application, enhanced root phenotypes, and restoration of degraded lands and o...

Plant communities and their ecosystem functions are expected to be more resilient to future habitat fragmentation and deterioration if the species comprising the communities have a wide range of dispersal and persistence strategies. However, the extent to which the diversity of dispersal and persistence traits in plant communities is determined by the current and historical characteristics of s...

The possibilities for research and restoration of the often damaged fragmented historic gardens in Hungary were relatively limited past, but thanks to funds provided by European Union, more than 20 reconstructed between 2007 2013. Since then 18 further sites had chance partial (covering at least surroundings mansions) framework National Mansion Castle Programme. Historic have an outstanding imp...

Severe declines in biodiversity have been well documented for many taxonomic groups due to intensification of agricultural practices. Establishment and appropriate management of arable field margins can improve the diversity and abundance of invertebrate groups; however, there is much less research on field margins within grassland systems. Three grassland field margin treatments (fencing off t...

Fire suppression in grassland systems that are adapted to episodic fire has contributed to the recruitment of woody species in grasslands worldwide. Even though the ecology of restoring these fire prone systems back to grassland states is becoming clearer, a major hurdle to the reintroduction of historic fires at a landscape scale is its social acceptability. Despite the growing body of literat...
