Much of Arizona can be characterized as having a bimodal (occurring twice per year) pattern of forage production which accompanies the seasonal summer monsoons and winter rains or snows. Forage quantity and quality decreases during the winter dormant season and the “summer slump” preceding summer rains (Figure 1). However, forage quality during any given month can be quite variable, depending upon the timing, frequency, amount of moisture, and the forage type selected.
