Role of seed mixes, biochar soil amendment, and the soil seed bank in improving Palouse Prairie restoration
… native species, and biochar increased native plant cover. In swale plots, native species richness was highest in low diversity perennial mix and annual seed addition treatments. However, neither treatment affected nonnative species cover. Species composition differed across topographic …

Riparian vegetation and the soil seed bank five years after dam removal on the Elwha River, Washington
… the former dam sites. To do this I surveyed plant species richness, community composition, and soil seed bank species richness and seed abundance on three riparian landforms (bars, floodplains, and terraces) located above, between, and below the dams. I surveyed the above ground vegetation in …

Variability in water use by phreatophytic Banksia woodland vegetation of the Swan Coastal Plain, Western Australia
… δ2H) were used to distinguish among potential plant water sources. Isotopic ratios from vascular water of the study species were compared with those of potential sources of precipitation, soil moisture and groundwater. The primary assumptions of this method were validated for the study species …

Remnant assessment and soil inoculation to inform large-scale prairie restoration at Eastern Washington University
… are relatively few studies of remnant prairie plant communities or soils, particularly in the Northern Palouse. From north to south in the Palouse Prairie Ecoregion, there are gradients in precipitation and temperature that affect plant communities. In addition, the Prairie is intersected by …

Land Use and Topography Impacts on Rangeland Soil Seed Bank Composition on Standing Rock Indian Reservation
<p>The purpose of this study was to contribute to the knowledge of community dynamics and the planning of restoration projects for degraded native prairie rangeland on Standing Rock Indian Reservation by utilizing the seeds stored naturally in the soil seed bank. The objectives of this study were: …

The Effects of Gibberellic Acid, Smoke Water, and Cold Stratification on the Germination of Native Perennial Seed
… evaluated the germination rates of twenty native plant species and their response to cold stratification as well as four chemical solution treatments—water (control), gibberellic acid, smoke water, and gibberellic acid with smoke water. Seeds were evaluated and counted twice a week. Of the twenty …
