Preliminary Results for the Bat Survey Along the Gardiner-to-Golden Gate Road Corridor, Yellowstone National Park, Wyoming, 2002
Mao J. 2002. Preliminary Results for the Bat Survey Along the Gardiner-to-Golden Gate Road Corridor, Yellowstone National Park, Wyoming, 2002. Yellowstone National Park, WY
A realignment of the road between the Golden Gate and the North Entrance of Yellowstone National Park (YNP), Wyoming, is being planned because of the instability of the current road portion along the Gardner River canyon. Possible construction plans include improving the existing Gardiner-Mammoth road, paving and diverting traffic to the Old Gardiner road, or building a new road over Mt. Everts (Fig. 1). Road construction, including alterations of cliff sites and rock formations, could adversely affect local bat populations. Previous bat surveys along the Mammoth-Norris road (Martinez 1999) and the Norris-Madison road (Hendricks 2000) identified 7 bat species (Long-eared myotis [Myotis evotis], Little Brown myotis [M lucifugus], Fringed myotis [M thysanodes], Big Brown bat [Eptescicus fuscus], Silver-haired bat [Lasionyteris noctivagans], Townsend's Big-eared bat [Corynorhinus townsendii], Hoary bat [Lasiurus cinereus]), as well as undifferentiated Myotis species. A known maternity colony exists in Devil's Kitchen in the Mammoth Terraces and is important for the Townsend's Big-eared bat, a species of special concern (Martinez 1999). In the current bat survey for the Gardiner/Mammoth area, we documented areas of bat activity and recorded bat foraging calls using ultrasonic detectors along the existing Gardiner-to-Golden Gate road and the Old Gardiner road.
