Abstract Grazing significantly affects the distribution, growth, and productivity of shrubs. In this study, we evaluated effects grazing disturbance on spatial distribution patterns interspecific relationships two desert shrubs, Ammopiptanthus mongolicus Sarcozygium xanthoxylon . Three types conditions were considered, including enclosed area (EA), seasonal rotational (SRGA), (GA) (100 m × 100 ...

Free and uncontrolled pasture grazing by animals may decrease soil aggregate stability through reductions in plant cover and subsequent soil organic C, and trampling. This could expose the soil surface layer to degradation and erosion. The objective of this study was to determine the influence of pasture management (free grazing, controlled grazing and long-term non-grazing regimes) on aggregat...

Research was initiated at the Texas Experimental Ranch in 1981 to quantify the effects of 2 stocking densities, equivalent to 14 and 42-paddock rotational grazing (RG) treatments, on aboveground biomass dynamics, aboveground net primary production (ANPP), and harvest efficiency of forage. Baseline data were collected in 1981 from 3 adjacent 30-ha paddocks in a lepaddock, cell designed RG treatm...
