The relationship between the weight of forage dry matter per unit area and the number of animal units at any one point in time; a forage-to-animal relationship. The inverse of grazing pressure. May be expressed as forage mass per animal unit (forage mass/animal unit at a specific time). This definition can be appropriately altered to be specific to herbage or browse by substituting these terms in place of forage.
