• A 3-Year Evaluation of Taste Aversion Coyote Control in Saskatchewan

      Gustavson, C. R.; Jowsey, J. R.; Milligan, D. N. (Society for Range Management, 1982-01-01)
      Taste aversion programs using lithium chloride (LiCl) in sheep baits and carcasses have been applied in Washington to one sheep herd for 2 years; applications have been made in California and in Saskatchewan on 46 herds over 3 years. Ten of these 46 herds were available for statistical analysis, indicating a significant reduction in the percent of sheep lost to coyotes. All applications have suggested reduced sheep losses to coyotes (Canis latrans). This method of predation control may cost less than traditional techniques, save sheep, and should allow coyotes to carry out positive functions in the ecosystem.
    • Vegetative and Reproductive Growth of Bluebunch Wheatgrass in Interior British Columbia

      Quinton, D. A.; McLean, A.; Stout, D. G. (Society for Range Management, 1982-01-01)
      Vegetative and reproductive growth of bluebunch wheatgrass in interior British Columbia has been documented for a 3-year period. Plants began growing immediately after snow melt in the spring, with measurable growth occurring where soils had warmed to 6 +/- 0.5 degrees C at 10-cm depths. Growth ceased from 7 May to 15 July and plants fully matured from 7 July to 10 August with actual dates for each particular site being dependent upon the local microclimate. Fall regrowth was not predictable, occurring only during 1973. Seed production was erratic, unpredictable from our data, and not of sufficient magnitude to sustain the grass population if improper grazing is allowed.
