It includes all vegetation,whether or not it is palatable to grazing animals. It includes the current year's growth of leaves,twigs,and fruits of woody plants. It does not include the increase in stem diameter of trees and shrubs. It is expressed in pounds per acre of air-dry vegetation. In a normal year,growing conditions are about average.Yields are adjusted to a common percent of air-dry moisture content. In areas that have similar climate and topography,differences in the kind and amount of vegetation produced on rangeland are closely related to the kind of soil. Effective management is based on the relationship between the soils and vegetation and water.
