The response of soils, streambanks and instream coliform bacteria levels to grazing management in a riparian area

Creator:

Bohn, Carolyn C.

Abstract:

This thesis describes a case study of the effects of five systems of grazing on watershed values in a deteriorated riparian area. Soil infiltration, bulk density and penetrability, streambank edge movement and coliform bacteria were monitored for seven years along a stream in the Blue Mountains of northeastern Oregon. For...

Infiltration, soil erosion, nitrogen loss and soil profile characteristics of Oregon lands occupied by three subspecies of Artemisia tridentata

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....

Watershed response to western juniper control

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...
