Book Description
Riparian zones can be identified by the presence of vegetation that requires free or unbound water or conditions that are more moist than normal (fig. 1) (Franklin and Dyrness 1973, Minore and Smith 1971). Riparian zones can vary considerably in size and vegetative complex because of the many combinations that can be created between water sources (fig. 2) and physical characteristics of a site. Such characteristics include gradient, aspect, topography, soil, type of stream bottom, water quality, elevation, and plant community (Odum 1971). All riparian zones within managed rangelands of the western United States, however, have the following in common: (1) they create well-defined habitat zones within the much drier surrounding areas; (2) they make up a minor proportion of the overall area; (3) they are generally more productive in terms of biomass-plant and animal-than the remainder of the area; and (4) they are a critical source of diversity within rangelands (fig. 3). Carothers (1977), Carothers and Johnson (19751, and Curtis and Ripley (1975) have prepared summary papers on the subject of riparian habitats as associated with both range and forest areas.

Book Description
Plant communities in the Great Basin of southeastern Oregon are described, and a field key is provided. The value of a plant communitys vertical and horizontal structure and the seasonal availability of its forage are examined in relation to wildlife habitat in managed rangelands. Further, the importance of individual and combined plant communities to wildlife in managed rangelands is discussed, and management alternatives are presented.

Book Description
"Southeastern Oregon has a variety of fish habitats which include major rivers, tributary streams, large and small reservoirs, lakes, and springs. These habitats are directly related to and highly dependent on the conditions of the surrounding rangeland watersheds. Satterlund (1975, p. 22) put it this way: "Rangelands may yield little water, but they are second only to cultivated lands as a source of water quality problems." It may be fairly stated, therefore, that man's agricultural activities in rangelands of southeastern Oregon have altered aquatic habitats more than any other land use."
