  • Range management is the art and science of obtaining sustainable animal production on native rangeland while also maintaining the natural resources.
  • There are four basic principles of range management:
    • Balance the number of animals with available forage supply.
    • Obtain a uniform distribution of animals over the range.
    • Alternate periods of grazing and rest to manage and maintain the vegetation.
    • Use the kinds of livestock most suited to the forage supply and the objectives of management.

  • The principles of range management are based on two fundamental ecological principles:
    • Physical factors, plants, and animals function as a unit and any change in one factor, such as that caused by fire or grazing, changes the whole system.
    • Vegetation changes are natural phenomena, which follow certain patterns.

  • Soil and vegetation on native rangelands developed together over time under the prevailing climate. The vegetation community that develops on a specific soil under a specific climate is called the climax community. This plant community is relatively stable, capable of perpetuating itself, and fully uses the available moisture, nutrients, and solar energy.
  • Four natural laws help explain range ecology:
    • If we keep down the shoot, we kill the root. Green leaves make the food that sustains plant roots. If too much leaf area is repeatedly harvested, the root starves and shortens, limiting the plants ability to reach moisture and soil nutrients. Eventually plants die.
    • Native stands abhor a vacuum and try to keep soil covered with vegetation. If grazing removes taller, more productive grasses, forbs, shrubs and unpalatable plants and low-growing grasses will fill the empty spaces.
    • Changes in vegetation proceed until there is a combination of plants that fit the soil and climate so perfectly that no other plants can move in. This is the climax community.
    • The principal factor limiting growth in grassland climates is water supply. More water is stored in soil covered with vegetation or a mulch of old growth than in bare soil. Bare soil increases moisture losses from evaporation and run off. Moisture conservation is critical on rangeland.
