Abstract: Pinyon-juniper woodlands are not normally considered a high water-yielding type largely because of the low precipitation amounts and high evapotranspiration rates encountered. Nevertheless, a recommendation was made in the 1950s to evaluate the effectiveness of increasing water yields by converting pinyon-juniper overstories to herbaceous covers. A series of process and plot studies and watershed-level experiments were carried out in acting upon this recommendation. It was concluded, however, that the potentials for increasing water yields through conversion treatments is "poor" in the region. A summary of these research findings is presented in this paper.
