17 Road verges have been proposed as refuges for vulnerable grassland species in the 18 modern, changing landscape, but little comparative knowledge exists on how 19 management regimes affect population dynamics of such species. We compared the 20 effects of various management regimes on population dynamics of Pimpinella saxifraga 21 in road verges and pastures, using elasticities and LTRE-anal...

The importance of managing land to optimize carbon sequestration for climate change mitigation is widely recognized, with grasslands being identified as having the potential to sequester additional carbon. However, most soil carbon inventories only consider surface soils, and most large-scale surveys group ecosystems into broad habitats without considering management intensity. Consequently, li...

Grassland is the first land use in the agricultural areas (AA) of Europe, covering, with rangeland, 56 million ha (33% of AA in EU). Grasslands are characterized by multiple functions and values but one of the most important is forage production for ruminants. In the “grassland region” milk production is connected with grassland management and proper utilisation, whereas in other parts of Europ...

Grassland, as one of the most important ecosystems on Earth, experiences fires that affect the local ecology, economy and society. Notably, grassland fires occur frequently each year in northeastern China. Fire occurrence is a complex problem with multiple causes, such as natural factors, human activities and land use. This paper investigates the disruptive effects of grassland fire in the nort...

Establishing grasslands has important implications for wildlife, especially in areas historically rich in grasslands that have since been converted to row crop agriculture. Most grasslands established under farm conservation programs have replaced annual crops with perennial cover that provides year-round resources for wildlife. This change in land use has had a huge influence on grassland bird...

This circular provides an overview of the use of fire in grassland management. It describes the history and importance of fire in the grassland ecosystem, how plants respond to fire, and the uses and potential benefits of prescribed fire. It also summarizes fire planning and legal and safety considerations. And finally, it provides guidance on some special uses of fire. when burning conditions ...

Grassland introduction into intensively managed agricultural landscapes may enhance soil organic matter (SOM) content and ecosystem services. However, the magnitude of this effect depends on grassland management practices, and their influence on the soil system. The aim of this paper is to highlight these impacts and their consequences for SOM dynamics and element cycling. We focused in particu...

Studying the responses of soil respiration (Rs) to soil management changes is critical for enhancing our understanding of the global carbon cycle and has practical implications for grassland management. Therefore, the objectives of this study were (1) quantify daily and seasonal patterns of Rs, (2) evaluate the influence of abiotic factors on Rs, and (3) detect the effects of soil management ch...
