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.

This synthesis discusses that fire can be used to either control invasive species or to restore historical fire regimes. However, the decision to use fire as a management tool must consider the potential interrelationships between fire and invasive species. Historical fire regimes did not occur in the presence of many invasive plants that are currently widespread, and the use of fire may not be a feasible or appropriate management action if fire-tolerant invasive plants are present. The management of fire and invasive plants must be closely integrated for each to be managed effectively.

This study highlights that vast areas of the arid shadscale zone have been rehabilitated through management, but direct plantings of both native and introduced species usually have failed. Future success will likely be with native plants, including shrubs, adapted to the particular site.
