3. Rotation grazing to permit forage growth periods for natural restoration of vegetative cover, on a regular sequence.
When specific herdsmen are assigned well-defined grassland areas for their sole use, then it becomes feasible to establish a pattern of rotating the grazing herd over the available areas. By dividing the total areas into four or more sectors, the livestock herd maybe grazed for a few weeks on each sector in rotation. This provides every sector with a rest period for regrowth. If the season when rains occur, for example, is four months, the grazing herd should not be kept on any single sector for more than one month. The concept is to control grazing pressure so that all sectors are used about equally during the full grazing season.
It is highly desirable to select a different sector each year, for protection from grazing throughout the entire growing season so that natural seed production and seedling establishment can occur. It is desirable that each sector be protected in this manner for natural rejuvenation about once every three to five years. Experience on several continents has shown that forage production and livestock carrying capacity can be markedly increased by this practice.
