Creator:: Frissell, Christopher Andrew, 1960-
Abstract:: As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...

Creator:: Zernel, John Joseph, 1945-
Abstract:: John Wesley Powell worked actively for public land system reform while a director of geographical and geological surveys in the West from 1869 to 1894. Although this has won him acclaim as a conservationist, the basis of Powell's linkage of reform with scientific work is poorly understood. A study of...

Creator:: Jensen, Mark E.
Abstract:: Relationships between sagebrush-dominated plant communities and soil-site characteristics were examined on 372 relatively undisturbed rangeland sites of the Humboldt National Forest, in northeastern Nevada. Plant species production data were analyzed by TWINSPAN to develop a hierarchical, floristic-based community type (C.T.) classification. Seventeen C.T.s were identified in this analysis and named...

Creator:: Everett, Richard L.
Abstract:: Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...

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...

Creator:: Harris, Norman Rex
Abstract:: Small herds of cows were observed and spatially mapped over continuous twenty-four hour periods. Treatments were implemented that investigated the effect of water site and supplementation on animal distribution patterns. A series of six observation periods constituted each observation series. Observation series were repeated winter (January) and summer (July) for...

Creator:: Crane, Stuart R.
Abstract:: The indiscriminate release of fecal bacteria to the environment can present a public health hazard when pathogenic species gain access to drinking and recreational water sources. The extent of bacterial contamination of surface and ground waters associated with animal production units and waste application areas seems largely dependent on the...
