Spanish ranching as it was practiced in Texas formed the basis for the American cattle industry, which drew many of its original cattle from the mission herds. The Spanish also brought to the San Antonio valley a specialized method of farming that used irrigation. Livestock, including cattle, horses, mules, sheep, and goats, was brought to Texas by the early settlers, such as Jose de Escandon. The Franciscans in Texas were the primary caregivers of the livestock. They were successful in the San Antonio area, but the settlements in East Texas were not.
