Residual biomass refers to the weight of vegetation remaining after grazing is concluded. Residual biomass has important rangeland management ramifications because it acts as the source of future plant growth and as soil protection. For these reasons, residual biomass is a useful goal upon which to interpret utilization and base decisions concerning stocking rates. Residual biomass can be directly sampled using any of the methods to determine biomass.
