Plant H"2O relations and soil moisture depletion and recharge were followed in a stand of Artemisia tridentata near Washtucna, Washington during 1973 and 1974. Precipitation during the 1972-73 recharge season was 14.5 cm, 11 cm below normal. The 1973-74 precipitation was 35.7 cm, or 10 cm above normal. The 2 yr were therefore ideal for comparing plant behavior on wet vs. dry years. Soil moisture was depleted to around -70 bars in 1973 and -60 bars in 1974 to depths of 2.5 m. Leaf H"2O potentials were -10 bars in the spring and decreased to -50 to -60 bars in the summer of 1973. In 1974, summer leaf H"2O potential was -30 bars. Osmotic potentials were around -20 bars in the spring of 1973 and throughout the spring...

The basic factors controlling competitive relationships between perennials and annuals on our ranges must be thoroughly understood if more than trial and error attempts at restoration are to be made. It is the objective of the present study to increase such understanding. Published in Ecological Monographs, volume 37, issue 2, on pages 89 - 111, in 1967.
