A study conducted by a group of four researchers in Mongolia finds the quantitative effects of grazing on a grassland structure. To quantitatively asses the effects of grazing, these researchers divided the grassland in two types of plots; one fenced and the other where grazing was kept continuing. They also installed cameras for photography after every ten minutes. This study was continued for three years (2016-2018).
The new method developed by these researchers calculated the Grazing Intensity (GI). They quantitatively assessed the seasonal and inter-annual variation and spatial differences in GI.
Their results indicated that;
The structure and function of grassland were significantly affected by goats, more than any other livestock.
With increase in GI, soil organic carbon, CO2 fluxes, total nitrogen and above ground biomass were decreased.
