Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Creator:: Swanson, Sherman R.
Abstract:: Infiltration, soil erosion, nitrogen loss and soil profile characteristics were measured on 36 sites representing land occupied by Artemisia tridentata ssp. tridentate, wyomingensis, and vaseyana. Infiltration, soil erosion, and nitrogen loss were strongly correlated but highly variable. Soil loss, but not infiltration or nitrogen loss was significantly different between subspecies....
