This professional paper reviews both the technical and policy aspects of the Forest Service practice of aerially seeding grass to rehabilitate areas burned by forest fires. Assessment of the state of knowledge covers four main questions : Does seeded grass establish and grow ? Does grass seeding reduce erosion ? What impacts does grass seeding have on native flora andsuccessional patterns ? How might grass seeding affect site productivity ? Recent literature suggests that the effectiveness of grass seeding is still in doubt, and that potential adverse consequences on natural processes are poorly understood. As a case study, postfire monitoring on the l<^j£&iyon Creek Fire shows that ever with a good growing season, establishment of seeded grass is highly variable across a wide range of site conditions. Seeded grasses produced the most cover on aoist aspect sites, at lower elevations, and on the gentler slopes. An evaluation of the monitoring methods employed suggests many refinements : notably the need for paired treatment and control plots. arid the need to integrate,research-into operational monitoring of land management practices. A critical review of the implementation and administration of emergency burn rehabilitation traces its fiscal and statutory foundations and current adminstrative framework. The main flaw in the policy is that it fails to provide ; for evaluation of its " : effectiveness in meeting its objectives. Recommendations include revision of the Forest Service rehabilitation Handbook to improve costeffectiveness analyses, and establishment of coordination, technical assistance, and funding of operational monitoring studies across the Region.
