Revegetation Trials in the Pinedale Anticline Project Area.

摘要

Critical wildlife habitat supporting mule deer, antelope, and sage grouse in high elevation rangeland and sagebrush ecosystems of southwest Wyoming is threatened by energy development and residential sprawl, resulting in a declining forage base. Restoring disturbances with diverse plant communities is needed. Our objectives were to assess establishment and persistence of native grass, forb, and shrubs, and to test seed mixtures and seeding techniques. In October 2005, 72 entries of 50 native species were drill-seeded on a reclaimed well-pad site, in single-species plots in a randomized complete block design with four replications. Also, two seed mixtures were broadcast- and drill-seeded, and one seed mixture was hydroseeded on disturbed areas adjacent to the plots.
