Analysis of hydrology and erosion in small, paired watersheds in a juniper-sagebrush area of central Oregon

Creator:

Fisher, Michael, (Michael Patrick), 1966-

Abstract:

Current research indicates that the expansion of western juniper can inhibit soil water retention, storage and prolonged releases from watersheds. This phenomenon is of great importance in eastern Oregon, as western juniper is encroaching into sagebrush/grass communities with a correlated reduction in herbaceous ground cover, resulting in reduced infiltration rates...

Paired watershed ecological analysis

Creator:

Fisher, Michael, (Michael Patrick), 1966-

Abstract:

This study was designed to provide a physical and ecological analysis of paired watersheds in the semi-arid western juniper (Juniperus occidentalis) woodlands of Central Oregon. Instrumentation and monitoring was accomplished in Jensen and Mays watersheds as the preliminary portion of a longer term project. Instrumentation was designed to address changes...

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...
