    • Coyote Control: the Public Response

      Arthur, L. M. (Society for Range Management, 1981-01-01)
      A nationwide survey of public attitudes toward coyote control was conducted in 1976. Results from a set of questions addressing related wildlife issues revealed opposition to the killing of animals for food or for population control of predatory species. Forty-five percent also disapproved of legal game hunting. Only incident specific predator control was endorsed by most respondents. Two-thirds of the respondents were aware of the coyote control issue or interested in it and were asked questions about coyote control in particular. Control killing of coyotes, even at risk to nontarget animals, received increasingly more approval as lamb losses were said to increase. However, given a choice of control methods, most respondents preferred the experimental, nonlethal methods. Of currently used lethal methods, fast acting poisons and shooting from the ground were judged more acceptable.
    • Autumn Mule Deer Foods on Heavily Grazed Cattle Ranges in Northwestern Colorado

      Lucich, G. C.; Hansen, R. M. (Society for Range Management, 1981-01-01)
      The botanical composition of the diets of domestic cattle and mule deer (Odocoileus hemionus) was estimated by microscopically examining fecal samples collected on deer winter ranges heavily used by cattle. Diet overlap ranged from 1 to 22% (x = 12%) on the nine areas studied. When cattle are forced from a grass dominated diet to browse forage on overgrazed ranges, diet overlap and therefore forage competition increases between deer and cattle.
    • A Comparison of Continuous and Rotational Grazing

      Walton, P. D.; Martinez, R.; Bailey, A. W. (Society for Range Management, 1981-01-01)
      Continuous and rotational grazing of a brome-alfalfa-creeping red fescue pasture was compared at the University of Alberta Ranch in 1975, 1976, 1977, and 1978. Productivity, in terms of animal weight gain and dry-matter consumption, was studied together with changes in the sward composition. In 1977 and 1978 the weight gains from the rotationally grazed areas were nearly double those obtained from continuous grazing (218 vs 119 kg/ha). The percentage by weight of alfalfa in the sward increased under rotational grazing from 23 to 47%. The herbage in the rotationally grazed field was more digestible and contained more calcium, magnesium, copper, and crude protein than did that in the continuously grazed area. Animals in the continuously grazed fields spent 2.4 hours longer per day grazing than did the animals which were rotationally grazed.
