    Abstract
    Alteration of stream channel morphology by cattle and associated streambank erosion is a concern on rangeland watersheds. The objective of this study was to determine changes in stream channel morphology in response to 5 grazing treatments applied to 0.4 ha pastures and replicated on 3 intermittent streams at the San Joaquin Experimental Range in the central Sierra Nevada foothills of California. Baseline stream channel morphology parameters were determined along 10 transects in each pasture in June 1994. Seasonal grazing treatments (no grazing, wet season moderate, wet season concentrated, dry season moderate, and dry season concentrated) were repeated annually over 4 years beginning in July 1994. Stream channel morphology parameters were measured annually from 1995-1998. When stream morphological responses were averaged across years, there were no detectable effects of grazing on the parameters measured. Year effects and their interaction with grazing were significant, primarily for stream morphological parameters that included channel depth in their measurement or calculation. Channel depth increased significantly in the ungrazed controls, but did not change due to any grazing treatment. These results indicate that grazing had little effect on the morphology of these bedrock limited, intermittent stream channels.

      Development and Evaluation of Habitat Suitability Criteria for Native Fishes and Assessment of the Relationship Among Riparian Areas and Stream Macrohabitats Type and Fish Presence in Four Central Arizona Streams

      Bonar, Dr. Scott A.; Nemec, Zach; Bogan, Dr. Michael T.; Wissler, Craig A. (The University of Arizona., 2018)
      Habitat loss is an important reason for fish fauna declines in the southwestern U.S. Several studies have defined habitat conditions for selected native fish species in Arizona, yet habitat use can vary across streams due to a variety of biological and physical factors. In addition, previous studies have focused on effects of instream habitat characteristics and less on how riparian areas structure aquatic communities of the Southwest. Riparian areas affect aquatic communities in a variety of ways, including structuring instream habitat. Macrohabitat (riffle, run, pool) is an important determinant of fish use, and little is known about the effect of riparian vegetation and associated land use activities on the formation of macrohabitat. Therefore, the objectives of my study were to 1) evaluate suitable habitat for native Arizona species, and 2) to investigate the relationships among riparian vegetation and stream macrohabitats type and fish presence in four central Arizona streams. Fish and habitat data were collected in four streams along the Mogollon Rim in Arizona during the 2017 summer field season at base flow conditions. I used the National Hydrography Dataset (NHD) and National Agricultural Imagery Program (NAIP) aerial imagery to estimate the amount of vegetation cover within the riparian areas of each stream. I developed habitat suitability criteria for four native species in three streams. Most generalized criteria did not transfer among study streams, similar to finding from past studies suggesting that stream-specific criteria were more accurate. I found that Smallmouth Bass and Red Shiner had a negative relationship to canopy cover, possibly explained by high temperature tolerances of both species. Desert Sucker and Speckled Dace presence were positively related to presence of riffle habitat, as has been noted in previous habitat studies. Riffle habitat was positively related to increases in riparian vegetation cover. These results can inform researchers, agencies and stakeholders who study and manage Arizona’s riparian areas and instream habitat.

      Optimal Placement of Off-Stream Water Sources for Ephemeral Stream Recovery

      Rigge, Matthew; Smart, Alexander; Wylie, Bruce (Society for Range Management, 2013-07-01)
      Uneven and/or inefficient livestock distribution is often a product of an inadequate number and distribution of watering points. Placement of off-stream water practices (OSWP) in pastures is a key consideration in rangeland management plans and is critical to achieving riparian recovery by improving grazing evenness, while improving livestock performance. Effective OSWP placement also minimizes the impacts of livestock use radiating from OSWP, known as the ‘‘piosphere.’’ The objective of this study was to provide land managers with recommendations for the optimum placement of OSWP. Specifically, we aimed to provide minimum offset distances of OSWP to streams and assess the effective range of OSWP using Normalized Difference Vegetation Index (NDVI) values, an indicator of live standing crop. NDVI values were determined from a time-series of Satellite Pour l’Observation de la Terre (SPOT) 20-m images of western South Dakota mixed-grass prairie. The NDVI values in ephemeral stream channels (in-channel) and uplands were extracted from pre- and post-OSWP images taken in 1989 and 2010, respectively. NDVI values were normalized to a reference imagine and subsequently by ecological site to produce nNDVI. Our results demonstrate a significant (P<0.05) increase in the nNDVI values of in-channel vegetation within 1 250 m of OSWP following their implementation. The area of piospheres (n=9) increased with pasture size (R2=0.49, P=0.05) and increased with average distance to OSWP in a pasture (R2=0.43, P=0.07). Piospheric reduction in nNDVI was observed within 200 m of OSWP, occasionally overlapping in-channel areas. The findings of this study suggest placement of OSWP 200 to 1 250 m from streams to achieve optimal results. These results can be used to increase grazing efficiency by effectively placing OSWP and insure that piospheres do not overlap ecologically important in-channel areas.
