No Action Alternative (Alt. B): Under the existing condition for reptiles and<br />

amphibians there are 42 miles of motorized routes in the Mexican gartersnake analysis<br />

area, 138 motorized routes in the Arizona toad and narrow headed gartersnake analysis<br />

area, and 25 miles of motorized routes in the Reticulate Gila monster analysis area.<br />

These routes continue to cause habitat loss and the potential for direct effects like vehicle<br />

collision, poaching, and collection. The potential disturbance zone for Mexican<br />

gartersnake is 2,330 acres, 6,858 acres for Arizona toad and narrow headed gartersnake,<br />

and 3,905 acres for Reticulate Gila monster. Within these potential disturbance zones<br />

motorized routes continue to cause the potential for disturbance, displacement, avoidance<br />

and harassment.<br />
