Technical Abstract: We have previously collected, evaluated, and released germplasm of Dalea ornata and Astragalus filipes. We also determined the optimal seed scarification techniques, planting depths, and soil types for seedling emergence. However, these results are just a couple of steps in the path to their utilization in revegetation. In this study we planted the two species in three dryland sites in Oregon, and tested if fall and spring planting leads to higher seedling emergence rates. We found that for Astragalus filipes fall plantings are generally more successul while early spring plantings were more successful for Dalea ornata. During dry years, neither plant germinated. Even when climates were more suitable and many plants germinated and emerged from the soil, summer aridity thinned the stands to just a few plants per row.
