Abstract:
Reported here are preliminary analyses of the impact of a 500 kV transmission line construction on seven radio collared desert bighorn sheep (Ovis canadensis mexicana) in the Dome Rock Mountains of western Arizona. Seven hundred four preconstruction relocations are compared to 365 construction period relocations. One ewe and one ram shifted their activity toward the area of transmission line construction, and two ewes appear to have slightly shifted their activity away from the construction activity. Two bighorn increased the number of times they traversed the line during the construction period.
