Thesis (M.S.)--University of Wyoming, 2015.

The ecological effects of roads and the science of their restoration have been extensively studied and documented. Efforts to close and restore obsolete roads are taking place on private, state and Federal lands. Although numerous restoration methods and treatments have been explored, the nuances of individual sites present their own challenges and learning opportunities. This study took place on The Nature Conservancy's Tensleep Preserve, in north central Wyoming where a majority of roads had been closed to vehicle traffic for 6-10 years. We measured the effects of several known restoration methods (raking, seeding, mulching and imprinting) on vegetative and soil communities. Eight months after planting, the average emerged seedling density for all four species (Idaho fescue Festuca idahoensis, Western wheatgrass Pascopyrum smithii, Mountain lupine Lupinus alpestris and Green needlegrass Nassella viridula ) was low (<0.5%). Green needlegrass and Idaho fescue showed significant effects among treatments while Western wheat and Mountian lupine did not. There were no significant treatment effects on bulk density, soil microbial community (phospolipid fatty acids, PLFA), infiltration or vegetative cover. Bare ground was significantly higher in plots that were raked and seeded (Treatment 2) and plots that were raked, seeded and mulched (Treatment 3) than in the control. There was not a significant difference in bare ground between the control and plots that were raked, seeded, mulched and imprinted (Treatment 4). We concluded that long-term monitoring would provide a more accurate assessment of vegetative and soil quality response to treatments.
