Phenological changes within a growth season were investigated in two grazed, seminatural grasslands in southern Sweden. On four occasions during the growth season, two independent observers recorded plant frequency and percentage cover. The vegetation data sets were analysed with ordination methods. The temporal changes were highly significant, but accounted for only a small part of the total v...

Fire and grazing, key determinants of structure and function of savanna grasslands worldwide, have been extensively altered by humans. We used existing long-term manipulations of fire and grazing in North American and South African mesic savanna grasslands, as well as new experiments, to determine whether the impacts of fire and grazing by large herbivores differed between these systems. We fou...

The effect of nitrogen deposition on the species richness of acid grasslands in Denmark: a comparison with a sudy performed on a European scale Journal Article How to cite: Damgaard, Christian; Jensen, Lennarth; Frohn, Lise Marie; Borchsenius, Finn; Nielsen, Knud Erik; Ejrnæs, Rasmus and Stevens, Carly J. (2011). The effect of nitrogen deposition on the species richness of acid grasslands in De...

The immediate need to understand the complex responses of grasslands to climate change, to ensure food supplies and to mitigate future climate change through carbon sequestration, necessitate a global, synthesized approach. Numerous manipulative experiments have altered temperature or precipitation, often in conjunction with other interacting factors such as grazing, to understand potential eff...

The Central Plains of Western Canada comprise the Prairies Ecozone and the Boreal Plains Ecozone. The former has the most grasslands and is divided into seven ecoregions: Mixed Grassland, Cypress Upland, Moist Mixed Grassland, and Fescue Grassland in southern Alberta and Saskatchewan; Aspen Parkland, which extends in an arc from central Alberta and Saskatchewan southeast to southwestern Manitob...

In a cultural-ecological perspective of New Zealand pastoralism the amount and form of energy supplements at different stages of pastoral development are characterized and prospects for sustainability discussed. The history of the pastoral exploitation of the tussock grasslands of South Island, New Zealand is reviewed with particular attention to physiognomic changes brought about by early fire...

Many western grasslands and scrublands are being overrun by Mediterranean annual grasses that are a limiting impediment to grassland restoration throughout the western United States (Kay et al. 1981; Dyer and Rice 1997, 1999; Brown and Rice 2000). Conserving and restoring these invaded ecosystems are important biodiversity goals. Restoring perennial grasslands can also increase the forage quali...

On account of their ecological, economical and cultural significance, grasslands are an important mark and a unique heritage in Jammu and Kashmir. However, the details of distribution of vast reserves of soil organic carbon (SOC) in these ecosystems are not well known because most of the previous investigations on these ecosystems have been devoted towards highlighting their importance as repos...

Resulting from centuries of traditional animal husbandry, extensive grasslands belong to the most important natural tourism resources in Central Europe adding to the amenity values of many landscapes. Facing agricultural market pressures, they are endangered by agricultural intensification as well as by abandonment. Both developments threaten grassland values for tourists and recreationists. Ho...
