Restoration prospects for Heitutan degraded grassland in the Sanjiangyuan [PDF]

Journal of Mountain Science, 2013
Abstract In many ecosystems ungulates have coexisted with grasslands over long periods of time. However, high densities of grazing animals may change the floristic and structural characteristics of vegetation, reduce biodiversity, and increase soil erosion, potentially triggering abrupt and rapid changes in ecosystem condition.

Input of nitrogen from N2 fixation to northern grasslands [PDF]

, 2005
Forage legumes form N2-fixing symbioses with rhizobia and may thus make substantial contributions to the N pool in grasslands. However, to optimize their use as sources of N, it is important to elucidate the effects of management factors that influence ...
