Restoring Tallgrass Prairie and Grassland Bird Populations in Tall Fescue Pastures With Winter Grazing
Restoration of grasslands dominated by tall fescue (Schedonorus phoenix [Scop.] Holub) to native tallgrass prairie usually requires burning, herbicides, or reseeding. We tested seasonal grazing by livestock in winter, combined with cessation of fertilization, as a restoration tool for modifying the competitive dynamics among herbaceous plants to restore tallgrass prairie communities in southeas...
متن کاملThe Impacts of Global Climate Change on Grassland Ecosystems
Global climate change, induced by increase in the concentration of greenhouse gases in the atmosphere, can affect the growth and community structure of grassland ecosystems in two ways. The first is directly through changes in atmospheric concentration of CO 2 and the second is indirectly through changes in temperature and rainfall. At higher latitudes, where growth is largely temperature limit...

Soil Sci. 82: 1–8. Livestock trampling impacts have been assessed in many Alberta grassland ecosystems, but the impacts of animal trampling on Aspen Boreal ecosystems have not been documented. This study compared...
متن کاملFire and grazing in a mesic tallgrass prairie: impacts on plant species and functional traits.
Fire is a globally distributed disturbance that impacts terrestrial ecosystems and has been proposed to be a global "herbivore." Fire, like herbivory, is a top-down driver that converts organic materials into inorganic products, alters community structure, and acts as an evolutionary agent. Though grazing and fire may have some comparable effects in grasslands, they do not have similar impacts ...
