Core Ideas Forage density has a linear relation to pasture height. The regression of forage density to pasture height is a measure of plant morphology within the sward. Forage mass is the product of forage density and pasture height resulting in a second‐order relation with zero intercept. The form of the second‐order relation of forage mass to pasture height can be diminishing return, linear, or exponential, depending on the distribution of forage density within the pasture.
