Title: Effectiveness of Postfire Seeding to Reduce Cheatgrass (Bromus tectorum) Growth and Reproduction in Recently Burned Sagebrush Steppe

Project Proposal Abstract: The positive relationship between cheatgrass (Bromus tectorum) and fire frequency is a major concern for land managers in semi-add shrublands throughout western North America, particularly in Great Basin sagebrush steppe. Management tools are needed to break this cycle, and in this project we will evaluate the use of postfire seeding to suppress the growth and reproduction of cheatgrass in low elevation sagebrush steppe dominated by Wyoming big sagebrush (Artenzisia tridentata ssp. wyomingensis). We will specifically evaluate the seeding of introduced versus native seed mixes, and grasses versus grasses plus leguminous forbs. We will also evaluate the postfire soil conditions, such as nutrient level and seedbank composition, that may influence the effectiveness of postfire seeding treatments. Effects of seeding on the species composition and abundance of native plants will also be evaluated. These data will be compiled during the initial 2 years after experimental burning. We will present this information as a set of recommendations for land managers to use when designing postfire seeding protocols, and as a set of working hypotheses for research scientists to use when formulating new studies to improve our knowledge of fire and invasive species ecology and management in sagebrush steppe.
