Many weeds are primarily a problem in pastoral areas. They have often been introduced through the movement of stock and feed, and are able to spread readily into disturbed and overgrazed areas. Weeds in pastoral areas decrease productivity through displacing useful species, and in some cases can poison or injure animals.

Most weeds of pastoral areas are unpalatable to stock, or are eaten only when young, and can outcompete the more palatable plants, especially if there is heavy grazing pressure.
