sheep (Ovis aries)
Sheep are used for conservation grazing. In mosaics of grass, tall herbs and scrub they prefer the grass and tall herbs, and graze very close to the ground to create lawns. They can control the regrowth of scrub to some extent, but (unlike goats) also need to eat grass to be fully nourished. Sheep were one of the first animals to be domesticated, and are thought to be descended from the mouflon (O. orientalis) which persists in the Near East in mountainous terrain.
