This paper analizes the human management of animal spaces in a rural area of Western Spain: the Sayago region (province of Zamora). This land is well known in the Spanish ethnographical literature because of its agrarian collectivist uses, in spite of the many changes that have happened in the last three decades. The author studies the traditional structures and contemporary Systems, as well in the smallholding exploitations as in the large rural states, the so-called dehesas.
