AbstractResearch was conducted on topsoiled strip mined lands at Colstrip, Mon., over a 6-year period to evaluate germination, survival, productivity, and cover characteristics of Eski sainfoin (Onobrychis viciaefolia), Lutana cicer milkvetch (Astragalus cicer), birdsfoot trefoil (Lotus corniculatus), and ranger and spreader alfalfa (Medicago sativa). Nitrogen and phosphorus fertilizer were applied at a low rate during the first year of study. None of the experimental units received irrigation. Lutana cicer milkvetch and both varieties of alfalfa demonstrated good establishment, survival, canopy cover, and productivity characteristics. Eski sainfoin showed good initial establishment but declined in following years. Birdsfoot trefoil appeared to be unsuitable for revegetation of mined lands at Colstrip. Spreader alfalfa was superior to ranger alfalfa in the parameters evaluated. Lutana cicer milkvetch showed much potential for mined lands revegetation in the study area because of site stabilization, persistence, palatability, nitrogen fixation, and productivity characteristics.
