| US93 Bighorn Sheep Study: Distribution and Trans-Highway Movements of Desert Bighorn Sheep in Northwestern Arizona. | |

| 英文摘要 | Desert bighorn sheep were monitored via satellite telemetry, ground observations, and track beds between 2004 and 2006, primarily to determine distribution and movements relative to mileposts (MP) 3 to 17 of U.S. Highway 93 in the Black Mountains of northwestern Arizona. Bighorns were distributed and moved throughout the study area, but locations of trans-highway movements were not random. Construction of a highway bypass structure between MP 0 and 3 had no apparent effects on permeability of the right-of-way corridor to bighorns. Bighorns concentrated trans-highway movements in the area of proposed highway realignments between MP 3 and 17 at five locations. The research team identified five continuous, linear, elevated guideways (ridgelines) in this area where bighorns concentrated trans-highway movements. Specifically, these ridgelines were located near MP 3.3, 5.1, 7.7, 12.2, and 15.3. Eighty-two percent of highway crossings between MP 3 and 17 occurred near ridgelines at MP 3.3, 5.1, and 12.2, and the research team concluded highway crossing structures at these locations likely would promote highway permeability at a level ensuring genetic heterogeneity and vigor of the resident desert bighorn sheep population. |
