The area around each water source is grazed more heavily. Placing additional water sources in more lightly grazed areas of a paddock can result in both reduced overgrazing around the original water source and increased grazing in less utilized areas of the paddock.

Many different grazing schemes can be used to maximize livestock grazing while protecting vegetation and water. All rotations involve providing a period of rest for the vegetation to recover after grazing. When designing a rotation, consider the following:

• length of time required for vegetation to recover (will change over the course of the growing season)

• frequency of rotation• ease of moving livestock between paddocks• livestock production goals• environmental and ecological goals

(water quality, wildlife habitat)
