Postfire seeding for erosion control: Effectiveness and impacts on native plant communities
Less than half of the studies reviewed in this synthesis showed reduced sediment movement with seeding. In all vegetation types, successful growth of seeded grasses—enough to affect erosion—appears to displace native or naturalized species, including shrub and tree seedlings. In burned sagebrush range, postfire seeding is frequently used to replace non-native cheatgrass (Bromus tectorum) with native or introduced bunchgrasses, with at least short-term success. In recent years, native species and sterile cereal grains have increasingly been used for seeding. Use of aerially applied straw mulch has increased as well, with the risk of weed introduction from contaminated bales.
