Rangeland drills to re-establish native plants
Sagebrush ecosystems of the Great Basin are rapidly being converted to annual grasslands dominated by invasive weeds such as cheatgrass (Bromus tectorum L.) which thrives following wildfire and competes with native plants. Restoring diverse plant communities containing perennial grasses, shrubs and forbs is an important priority in this region. Scientists in Boise have partnered with public and private agencies to evaluate the effectiveness of seeding techniques designed to re-establish native plants following fire.
This study examines the efficacy of seed zones for bluebunch wheatgrass to ensure successful establishment and allow for long-term adaptation by maintaining genetic diversity.
The cycle of annual weed invasion and wildfire has altered large expanses of western shrublands, disrupted ecosystem functioning, and increased wildfire size, intensity, and frequency.  These impacts are costly in terms of losses to native species and ecosystems, and also in risks to human life and property and wildfire-associated expenditures.  Post-fire rehabilitation provides an opportunity to stabilize and revegetate at-risk shrublands.
