Introduction and Instructions for Management Tools
Sustainable livestock production depends on reliable forage resources that maintain animal health and fecundity. Temporal and spatial variation in forage production in most range and pasture systems are closely linked to the timing and amount of precipitation.
Grazing management decisions are often based on a producer’s knowledge of past or average forage production levels with little certainty that sufficient precipitation will fall in time to produce what is anticipated. The cumulative effects of inaccurate grazing management decisions include poor Average Daily Gain in livestock, loss in soil fertility, increased rates of soil erosion, and establishment of weeds. Thus, development of a rainfall and forage production index that accounts for temporal and spatial patterns in precipitation inherent to a given locale will greatly improve the management decision process.
