The land imprinter and rangeland drill were compared for revegetation of a wildfire burn in the Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) vegetation type. Seeding trials were conducted on strips 152 m wide and 1.6 km long. Seeded species were fairway wheatgrass (Agropyron cristatum), luna pubescent wheatgrass (A. trichophorum), Russian wildrye (Elymus junceus), and Ladak alfalfa (Medicago sativa). Severe wind erosion on the study area occurred the first spring. Total seeded plant densities and cover were significantly higher with the imprinting treatment. Production of seeded plants was higher on the imprinted areas the first 2 years; thereafter, compensatory growth within the thinner drilled stand resulted in similar production levels between treatments. There was little difference in seeded plant establishment between soils.
