(Encyclopedia of the Great Plains) The pastores are a little-known Hispanic sheepherding group whose homeland was the grasslands of north-central New Mexico (Quechero, or Mescalero Plains).

... Economically, the pastores were part of either the partido system of herd management or a family business that owned and managed the flock. The New Mexico partido system, adapted from that of Spain, was a means of lending capital at interest that allowed a sheepherder to build up his own flock, thereby moving to the family business system.
